@binance: Over a month has passed since #Binance released the OTC Trading Portal. During this time, we’ve seen the Bitcoin halving event come and go and thought it would be interesting to share what users were buying/selling on the portal post-Bitcoin halving. https://t.co/OfMaa0Xgaa
My local bank in India doesn’t allow to transfer funds to international/foreign trading portal. Neither does it allow to buy bitcoin directly. Please help me by pass this shitty system.
Although there is one Indian Portal, but you have to keep bitcoins on their wallet online only... can’t transfer bitcoin to my hardware wallet or paper wallet... Also funds from my country to outside are highly monitored by shitty government we have.. any way to by pass it??? Need a solution to buy 0.1 bitcoin per week or so
Hi fellas, this is my first post on the darknet. I read today about the Empire Market and decided to post here about a tech that might help to end this charade of constant exit scams. My post is about a DLT-based open source decentralized marketplace that will hopefully initiate a paradigm shift in the free and private trade between individuals and ends the exit-scams and leaky databases problem once and for all. It is called the Open Marketplace V3.0 and is set to be released after 3 years of hard development work by Particl Project, including one year of public beta testing. My personal belief is that they are releasing to the world a game-changing/breaking product. At minimum, due to the open source nature of the project, this is a proof of concept that is bound to shift the global eCommerce paradigm into DeCommerce. I hope my own description below of the marketplace and its technology will fuel your interest to read more about it. My even bigger hope is that some of you will decide to become first-hand beta testers as soon as the Open Marketplace v3.0 hits the testnet (eta: a few weeks). The marketplace: The Open Marketplace is designed to be private by default and decentralized with no middlemen/intermediaries whatsoever. The trades are protected by two-way automated escrow via smart-contracts that de-incentivize and penalize dishonest behavior on both sides. The Open Marketplace takes no sales commissions and charges only a tiny listing fee (<0.01$) to prevent listing spamming. All the marketplace generated fees go to the nodes that provide the hardware infrastructure for the p2p network to operate. The nodes can be public or you can run them as Tor hidden services. The V3.0 that is set to be released will be the first version open to the wider public. It will allow anyone to create easily a decentralized personal storefront or a community market or simply buy and sell goods on the already existing markets. The user-created markets/storefronts can be visible on the marketplace if the access key is publicly announced or absolutely invisible to anyone that doesn't know the access key (held by the creator). This is an intentional privacy feature and simply put without going into many technical details, if you dont have market access key there is absolutely no way to see/detect that some market exists. The technology: The Open Marketplace is crypto-agnostic and currently supports payments in BTC, PART, ZCoin (DAI, NIX are next in the pipeline and many more to come). It uses as a settlement layer its native blockchain, which is an up-to-date Bitcoin codebase with added privacy features like CT, RingCT (up to 32 mixins), Stealth addresses, etc. These privacy features are used in combination to keep the financial data like escrows, transactions, etc private and most importantly un-linkable to the actual market buys/sells. For the actual user or markets related data exchange like posted listings, buy/sell flows, encrypted user communication, built-in cryptocurrency exchange, etc, the Open Marketplace uses a custom Bitmessage variant called SMSG, which allows metadata stripped encrypted data exchange. Last but not least the Open Marketplace client has a built-in option for using Tor network via proxy. The important people: The cypherpunks behind Particl's Open Marketplace have been passionate pioneers and OGs in the privacy DLT field. For example, they were the first ever to implement features like RingCT, Bulletproofs, PoS, cold staking, etc on a Bitcoin codebase. Their privacy features implementations have been audited successfully by several respectable academics and security R&D providers, like QuarksLab. The team has been so far focused on building without any marketing and thus have remained intentionally in the shadows but the latter is planned to change with the v3.0 release. One of the steps towards that will be the initiation of the long-planned Vendor On-boarding and Outreach Program and the release of the Particl Academy, an easy to understand and learn about the project portal. Me: I am a passionate freedom and privacy advocate that discovered the project 1.5 year ago and since then has become a member of their small but like-minded community ([email protected]/discord).
Decentr ($DEC) - foundational cross-chain and cross-platform DeFi protocol
Decentr is a protocol designed to make blockchain/DLT mainstream by allowing DeFi applications built on various blockchains to “talk to each other”. Decentr is a 100% secure and decentralised Web 3.0 protocol where users can apply PDV (personal data value) to increase APR on $DEC that users loan out as part of of our DeFi dLoan features, as well as it being applied at PoS when paying for stuff online. Decentr is also building a BAT competitor browser and Chrome/Firefox extension that acts as a gateway to 100% decentralised Web 3.0
Allows DeFi Dapps to access all Decentr’s dFintech features, including dLoan, dPay. Key innovation is that the protocols is based on a user’s ability to leverage the value of their data as exchangeable “currency”.
Decentr is building foundational chain-agnostic protocols that will support “true” 100% DeFi Dapps, a 100% secure and decentralised, user-centric alt economy. DeFi dApps inter-connected by Decentr can talk to each other and share PDV (personal data value) of their users. PDV is best described as a personalized “exchange rate” (in a sense social reputation where more effort leads to more rewards and NOT more capital to more rewards. ) between currencies that users apply at point-of-sale to make the cost of goods and services cheaper online. PDV is applied to the APR users earn on $DEC (native token) that they hold that they loan out as part of the investing pool. PDV will also allow uncollateralized loans on their dLoan platform, and also on platforms like Aave and Compound.
Decentr will implement ZKsync to get super cheap and super fast transactions across the ETH network. It is also working with HoloChain and Tomochain to allow connect their DeFi ecosystem to the Ethereum DeFi ecosystem. Decentr has DEEP TIES and a PARTNERSHIP with Holochain: https://medium.com/@DecentrNet/decentr-holochain-ama-29d662caed03
Decentr is also building a browser and Chrome/Firefox extension - a gateway that “transitions” Web 2.0 into a 100% decentralised Web 3.0 via their suite of decentralised dFintech and dCommunications features. The browser adds a 100% decentralised “user layer” to current blockchain protocols so that applications built on blockchain can actually “talk to each other”. The browser uses encryption all the time and the power of blockchain to keep private keys safe. Browser will offer a more robust and innovative type of blockchain storage and caching that is much faster than VPN or TOR. It will allow surfing .onion addresses as well as the regular ones. >>BAT browser 400m marketcap, DEC marketcap 4m<<
Decentr is researching a hardware application, powered by Decentr software, that would greatly enhance current IoT networks. It’s called a “Smart Chip Node” (SCN) and will adhere to 4G LTE standards (with in-built 5G capability), which means connectivity between devices will match or exceed current speed and connectivity, dramatically improving stability and coverage of standalone devices, such as a laptop or tablet, as well as IoT devices, such as home routers and modems.
Decentr uses Coinbase API to optimise integrated implementation of the user layer and Blockchain as a Service (BaaS) to allow users to leverage cloud-based solutions to build, host and use their own blockchain apps. Tierion’s technological infrastructure, the Chainpoint Proof protocol, will come into play whenever a user adds something in Tierion’s data store. Hyperledger Fabric and R3 Corda private blockchains are used as an immutable transaction database for data transfers, including the following tech: R3 Corda, Hyperledger Fabric, Ansible, Bitbucket Pipelines, AWS, Node.JS, GoLang, Kotlin and CouchDB.
Implements a system of layered security protocols based on a radically-new software architecture that combines Elliptic Curve Cryptography (ECC)4 and Sobol sequencing with a n-dimensional chain as part of AI-enhanced, platform-wide community consensus mechanism — a mechanism that assigns mutually agreed value to data and user security protocol upgrades (further encouraging enhanced data integrity) by deploying a Delegated Proof of Stake (DPoS) protocol.
Bank of England has reached out to Decenr to discuss the potential of a UK CBDC upon hearing about the potential of their tech. Decentr is consistent with their own R&D into a "dGBP" and they requested a top-level document for review >> Decentr created this proposal: https://decentr.net/files/Decentr_Consultancy_Doc_UK_CBDC.pdf
A fee is charged for every transaction using dPay whereby an exchange takes place between money (fiat and digital) and data, and vice versa, either as part of DeFi features or via a dApp built on Decentr. They are launching pilot programmes in the following industries:
Banking/PSP Industry: On Product launch, due to Decentr’s powerful PSP connections (including the worlds #2 PSP by volume), a medium-scale pilot program will be launched, which will seed the network with 150,000 PSP customers in primarily the Spanish/LAC markets, generating revenue from day one.
“Bricks and Mortar” Supermarket/Grocery Industry: Decentr aims to ensure the long-term competitiveness of “bricks and mortar” supermarkets against online-only grocery retailers, such as Amazon, by a) building secure tech that allows supermarkets to digitise every aspect of their supply chains and operational functions, while b) allowing supermarkets to leverage this incredibly valuable data as a liquid asset class. Expected revenue by Year 5: $114Mn per year.
Online Advertising Industry: Decentr’s 100% decentralised platform credits users secure data with payable value, in the form of PDV, for engaging with ads. The Brave browser was launched in 2012 and in 8 years has reached over 12 million monthly active users, accented by as many as 4.3 million daily active users.
TOKEN $DEC AND SALE
Decentr recently complete their token sale on a purchase portal powered by Dolomite where they raised $974,000 in 10 minutes for a total sale hardcap of 1.25M.

Updated list of Global Beermoney opportunities (+180!) - June 2020
Updated list of Global Beermoney opportunities (+180!) - June 2020
The current, and now previous, Beermoney Global list started nearly 5 years ago. It’s been updated and has grown over all that time, but it also became a hassle to keep current. It was time to build a new list from scratch based on my experience in the Beermoney world over all these years and all the contributions all of you have been making in this sub. The lists consist of opportunities that are available in at least one country that is not the US. This means there are sites which only work in Canada or the UK. There’s sites which are open to the whole world, but this does not mean everyone can really earn something on it. It’s all still very demographic and therefore location dependent. This list should give you a starting point to try out and find what works for you. I’m not using everything myself as I prefer to focus on a few, so not all are tested by me. They are found in this sub, other subreddits and other resources where people claim to have success. I’ve chosen the format of a simple table with the bare minimum of information to keep things clean. It includes a link, how you earn, personal payment proof if available and sign-up bonus codes if applicable. Some of these bonuses are also one-time use codes specifically made for this sub! For the ones I don’t have payment proof (yet) feel free to provide some as a comment or via modmail so others know it’s legit. I am working on detailed instructions for each method that I personally use which will include things like cashout minimum, cashout options, tips & tricks,... For now I’ve split things up based on the type of earning like passive or mobile. Because of this there’s sometimes an overlap as some are both passive and on mobile or both earning crypto and a GPT (Get Paid To) website. The lists are obviously not complete so I invite you to keep posting new ones in the sub, as a comment to this post, or in modmail. Especially if you have sites or apps which work for one single specific country I can start building a list, just like I did for The Netherlands and Belgium. If you recognize things which are in fact scams or not worth it let me know as well.
Get Paid To (Surveys, tasks, offers, videos, clicking links, play games, searching)
For The Netherlands there are a few very good options next to a bunch of ‘spaarprogramma’s. There ‘spaarprogramma’s are all the same where you receive and click a bunch of e-mails, advertisements, banners,... I advise you to create a separate e-mail address or use a good filter in your inbox as you will be spammed to death. I believe they can be a nice piece of beermoney but they take quite the effort.
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
Technology and some more:
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
Down the rabbit hole
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here. Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017. Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand. Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”.Scilla design story part 1
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
“Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
Smart contract on a sharded environment and state sharding
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
Business & Partnerships
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
Marketing & Community
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!
The danger when a majority of users is relying on SPV wallets (by belcher_)
This is a repost of a post by u/belcher_ on the bitcoin-dev mailinglist (source). I think it is a good description of why relying on SPV wallets (or someone else's node) can be dangerous for bitcoin from a "macro perspective. For clarification: SPV means "Simplified Payment Verification". In very simple words, it's a wallet that doesn't verify everything on the network (as opposed to what a full node does), and can be fooled in certain attack scenarios, as described below, f.ex.
For example, consider if bitcoin had 10000 users. 10 of them use a full node wallet while the other 9990 use an SPV wallet. If a miner attacked the system by printing infinite bitcoins and spending coins without a valid signature, then the 9990 SPV wallets would accept those fake coins as payment, and trade the coins amongst themselves. After a time those coins would likely be the ancestors of most active coins in the 9990-SPV-wallet ecosystem. Bitcoin would split into two currencies: full-node-coin and SPV-coin. Now the fraud miners may become well known, perhaps being published on bitcoin news portals, but the 9990-SPV-wallet ecosystem has a strong incentive to be against any rollback. Their recent transactions would disappear and they'd lose money. They would argue that they've already been using the coin for a while, and it works perfectly fine, and anyway a coin that can be spent in 9990 places is more useful than one that can be spent in just 10 places. The SPV-wallet community might even decide to use something like invalidateblock to make sure their SPV-coin doesn't get reorg'd out of existence. There'd also likely be a social attack, with every bitcoin community portal being flooded with bots and shills advocating the merits of SPV-coin. This is not a hypothetical because we already saw the same thing during the scalability conflict 2015-2017. Before you know it, "Bitcoin" would become SPV-coin with inflation and arbitrary seizure. Any normal user could download software called "Bitcoin wallet" which they trust and have used before, but instead of using Bitcoin they'd be using SPV-coin. You may be one of the 10 wallets backed by a full node, but that won't do much good to you when 9990 users happily use another coin as their medium of exchange.
Bittrex Review: One of the First Crypto Exchanges Part 2
3. Fiat Currency Deposits, Trading, and Withdrawals
Bittrex Global supports euro trading, deposits, and withdrawals for eligible personal and corporate accounts. Please note that euro trading is offered by Bittrex Global and subject to the Bittrex Global Terms of Service. There are three mechanisms available for depositing euros to your Bittrex Global account:
SEPA Credit Transfer
International Wire Transfer
Bittrex Global allows you to withdraw Euros to your bank account via either SEPA credit transfer or international wire transfer.
Crypto assets ensure that replenishment and all exchange transactions are kept through digital currency. Therefore, in case you need to withdraw cash, you must first convert it into Bitcoin (BTC). At the same time, there may be some other ways to refill the balance with US dollars, which entails filling a particular form for depositing in dollars—Fiat USD trading Request. To gain a digital currency on the exchange you need to visit your private account and find the Wallets section where all the wallets are shown. The platform creates a crypto address to which we transfer funds. Money can be credited to the exchange within two days, with the time required depending on the currency and mode of payment (e.g. bank transfer, credit or debit card, and so on). Therefore, after the transfer, the funds are credited to the exchange's internal wallet. In order to include a user account for depositing and withdrawing funds in dollars, Bittrex must add the user’s bank account to the white list. Therefore, to replenish the balance with fiat money, you must fill a special form.
Obtain approval for Fiat (USD) Trading, Deposits, and Withdrawals.
To do this, fill out and submit the form: https://bittrexglobal.zendesk.com/hc/en-us/requests/new?ticket_form_id=360000352300 https://preview.redd.it/jwcp2jguied51.jpg?width=861&format=pjpg&auto=webp&s=9ef519cbcf579cc3567e53b55af29fa154e342e3 Keep in mind that wire transfers can only be received from bank accounts approved through the fiat trading application. 2) Make sure your bank account has been whitelisted. Sign in to your Bittrex Global account. Go to the Holdings Tab. Type “US Dollar” in the search bar. Click the Withdraw button beneath Actions. All available whitelisted (approved) bank accounts will be shown. https://preview.redd.it/ldwmvt3wied51.jpg?width=974&format=pjpg&auto=webp&s=71d3da503e050f5b4d231184ea82f65fd477b671 3) Generate your USD deposit code. To get a USD deposit code, click the Holdings tab. Type “US dollar” in the search bar, click Deposit beneath Actions. Your USD deposit code will appear at the bottom of your Wire Transfer Instructions. Copy this code and input it in the memo/notes subject of the wire transfer form to your financial institution. https://preview.redd.it/pf7sowxxied51.jpg?width=974&format=pjpg&auto=webp&s=c99b3c10a1921254e8247c77a04f529bc60e290b Use your USD deposit code every time making wire transfers. Wire transfers cannot be processed without a correct USD deposit code. 4) Best practice: Use the wire transfer information provided in your USD wallet when asking your bank for assistance. Bittrex recommends that users resort to a local bank branch when sending wire transfers for the first time. To show wire info, enter the "US dollar” in the search bar at the bottom of the Holdings page. Then click Deposit beneath Actions. You will see all the wire information. Use the deposit data to fill out a wire transfer form correctly. In case the info does not appear or if you have questions, please contact Bittrex Global support. Make sure the wire transfer is not sent as an ACH transfer. ACH transfers aren't permitted so they will be banned. Be aware: Wire deposits (wires sent to Bittrex Global) CANNOT be initiated on the Bittrex Global webpage. Only withdrawal wires can be initiated on the webpage. All wire transfers must be processed from the bank account number that was provided to Bittrex Global, in your fiat money transfer application. 5) Wait for the amount to be credited to your Bittrex Account. All USD deposits are credited the same or next-business-day once settled in Bittrex's bank account. Wires take 5-10 days to settle. More delays will occur if the wire data does not fit the whitelist. Wire transfer charges: Bittrex exchange does not take any wire transfer fee. Please ask your bank about the commission it charges for sending or getting a wire transfer. International banks usually involve mediators so check the commission the intermediary charges for their services.

Cryptocurrency’s promise is to make money and payments universally accessible– to anyone, no matter where they are in the world. The Decentralized Finance (DeFi) or Open Finance movement takes that promise a step further. Imagine a global, open alternative to every financial service you use today — savings, loans, trading, insurance and more — accessible to anyone in the world with a smartphone and internet connection. This is now possible on smart contract blockchains, like Ethereum. “Smart contracts” are programs running on the blockchain that can execute automatically when certain conditions are met. These smart contracts enable developers to build far more sophisticated functionality than simply sending and receiving cryptocurrency. These programs are what we now call decentralized apps, or dapps. You can think of a dapp as an app that is built on decentralized technology, rather than being built and controlled by a single, centralized entity or company. (Get used to this word, dapp, you’ll be seeing it a lot from here on out.) While some of these concepts might sound futuristic–automated loans negotiated directly between two strangers in different parts of the world, without a bank in the middle– many of these dapps are already live today. There are DeFi dapps that allow you to create stablecoins (cryptocurrency whose value is pegged to the US dollar), lend out money and earn interest on your crypto, take out a loan, exchange one asset for another, go long or short assets, and implement automated, advanced investment strategies.
What differentiates these DeFi dapps from their traditional bank or Wall Street counterparts?
At their core, the operations of these businesses are not managed by an institution and its employees — instead the rules are written in code (or smart contract, as mentioned above). Once the smart contract is deployed to the blockchain, DeFi dapps can run themselves with little to no human intervention (although in practice developers often do maintain the dapps with upgrades or bug fixes). The code is transparent on the blockchain for anyone to audit. This builds a different kind of trust with users, because anyone has the opportunity to understand the contract’s functionality or find bugs. All transaction activity is also public for anyone to view. While this may raise privacy questions, transactions are pseudonymous by default, i.e. not tied directly to your real-life identity. Dapps are designed to be global from day one — Whether you’re in Texas or Tanzania, you have access to the same DeFi services and networks. Of course, local regulations may apply but, technically speaking, most DeFi apps are available to anyone with an internet connection. “Permissionless” to create, “permissionless” to participate — anyone can create DeFi apps, and anyone can use them. Unlike finance today, there are no gatekeepers or accounts with lengthy forms. Users interact directly with the smart contracts from their crypto wallets. Flexible user experience — don’t like the interface to a certain dapp? No problem — you can use a third party interface, or build your own. Smart contracts are like an open API that anyone can build an app for. Interoperable — new DeFi applications can be built or composed by combining other DeFi products like Lego pieces — e.g. stablecoins, decentralized exchanges, and prediction markets can be combined to form entirely new products. DeFi is now one of the fastest growing sectors in crypto. Industry observers measure traction with a unique new metric — “ETH locked in DeFi”. At the time of writing, users have deposited over $600 million worth of crypto into these smart contracts. Intrigued? Let’s take a closer look at just a few of the popular DeFi dapps out there that you can try today. You’ll need a cryptocurrency wallet with a built-in dapp browser (like Coinbase Wallet) to connect to these dapps. You can also use most of these dapps on desktop by selecting the Coinbase Wallet option and scanning a QR code. It’s still early days for dapps, so DeFi users should do their research on new products and services. Like any computer code, smart contracts can be vulnerable to both unintended programming mistakes and malicious hacks.
Stablecoin and Decentralized Reserve Bank: MakerDAO
Maker is a stablecoin project where each stablecoin (called DAI) is pegged to the US Dollar and is backed by collateral in the form of crypto. Stablecoins offer the programmability of crypto without the downside of volatility that you see with “traditional” cryptocurrencies like Bitcoin or Ethereum. You can try creating your own DAI stablecoin on the Maker Oasis dapp. Maker is more than just a stablecoin project, though–it aspires to be a decentralized reserve bank. People who hold a separate but related token, MKR, can vote on important decisions like the Stability Fee (similar to how the Federal Reserve’s Federal Open Market Committee votes on the Fed Funds rate). Another stablecoin with a different architecture is USD Coin (USDC), where every USDC token is backed by one US dollar held in an audited bank account. Borrow and Lend: Compound Compound is a blockchain-based borrowing and lending dapp — you can lend your crypto out and earn interest on it. Or maybe you need some money to pay the rent or buy groceries, but your funds are tied up in your crypto investments? You can deposit your crypto to the Compound smart contract as collateral, and borrow against it. The Compound contract automatically matches borrowers and lenders, and adjusts interest rates dynamically based on supply and demand. Other popular borrow/lend dapps are Dharma and dYdX. Aggregators like LoanScan track borrow/lend interest rates across the various dapps, so you can shop around for the best rates. Automated Token Exchange: Uniswap Uniswap is a cryptocurrency exchange run entirely on smart contracts, letting you trade popular tokens directly from your wallet. This is different from an exchange like Coinbase, which stores your crypto for you and holds your private keys for safekeeping. Uniswap uses an innovative mechanism known as Automated Market Making to automatically settle trades near the market price. In addition to trading, any user can become a liquidity provider, by supplying crypto to the Uniswap contract and earning a share of the exchange fees. This is called “pooling”. Other popular Decentralized Exchange platforms (DEXes) include 0x, AirSwap, Bancor, Kyber, IDEX, Paradex and Radar Relay. All have slightly different architectures. Prediction Markets: Augur Augur is a decentralized prediction market protocol. With Augur, you can vote on the outcome of events, except you put ‘skin in the game’ by attaching a value to your vote. Prediction market platforms like Augur and Guesser are nascent, but offer a view into a future where users can make better predictions by tapping into the wisdom of the crowd. Synthetic Assets: Synthetix Synthetix is a platform that lets users create and exchange synthetic versions of assets like gold, silver, cryptocurrencies and traditional currencies like the Euro. The synthetic assets are backed by excess collateral locked into the Synthetix contracts. No-loss savings games: PoolTogether The composability of DeFi lends itself to infinite new possibilities. PoolTogether is a no-loss game where participants deposit the DAI stablecoin into a common pot. At the end of each month, one lucky participant wins all the interest earned, and everyone gets their initial deposits back.
So what’s next for DeFi?
Money and finance have been around in one form or the other since the dawn of human civilization. Crypto is just the latest digital avatar. In upcoming years, we might see every financial service that we use in today’s fiat system being rebuilt for the crypto ecosystem. We’ve already seen asset issuance and exchange, borrowing, lending, custody, and derivatives built for crypto. What’s next? The first generation of DeFi dapps rely heavily on collateral as a safeguard. That is, you need to already own crypto and provide it as collateral in order to borrow more crypto. More traditional unsecured borrowing and lending will need to rely on an identity system, so that borrowers can build up credit and increase their borrowing power, much like today’s SSN and FICO scores. Unlike today’s identity and credit systems however, a decentralized identity will have to be both universal and privacy-preserving. We’re also seeing innovation in the insurance space. Many of today’s DeFi loans are overcollateralized (meaning that loans seem inherently safe because of the generous cushion of assets held in reserve). But the black swan for DeFi is smart contract vulnerabilities. If a hacker finds and exploits a bug in the open source code for a dapp, millions of dollars could be drained in an instant. Teams like Nexus Mutual are building decentralized insurance that would make users whole in the event of smart contract hacks. Another trend we’re seeing is better user experience. The first generation of dapps was built by blockchain enthusiasts for blockchain enthusiasts. These dapps did a great job of demonstrating exciting new DeFi possibilities, but the usability left something to be desired. The latest iterations of DeFi apps are prioritizing design and ease of use in order to take open finance to a wider audience. In the future, we expect that crypto wallets will be the portal to all your digital asset activity, just like an internet browser today is your portal to the world’s news and information. Imagine a dashboard that shows you not just what assets you own, but how much you have locked up in different open finance protocols–loans, pools, and insurance contracts. Across the DeFi ecosystem, we’re also seeing a move towards decentralizing governance and decision-making. Despite the word “decentralized” in DeFi, many projects today have master keys for the developers to shut down or disable dapps. This was done to allow for easy upgrades and provide an emergency shutoff valve in case of buggy code. However, as the code becomes more battle-tested, we expect developers will give up these backdoor switches. The DeFi community is experimenting with ways to allow stakeholders to vote on decisions, including through the use of blockchain-based Decentralized Autonomous Organizations (DAOs). Something magical is happening in the open financial system — crypto is bringing money online, and we’re seeing a quantum leap in what’s possible when it comes to the functionality of money. It’s a rare opportunity to see an entirely new industry blossom from scratch. The DeFi space will at first play catch up with today’s financial services industry. But over time, it’s hard to even fathom what innovations will come about when the power to build financial services is democratized to anyone who can write code.

dxDAO aims to power DeFi protocols through decentralized governance
I found this article on internet. It's repost of it to help educate people about all DXDao advantages: These are positive and necessary steps for DeFi. The new governance structures are intended to help coordinate across community stakeholders and make better decisions. These dynamics are influenced by the issues covered in Dose of DeFi, but I believe they deserve their own focused analysis. Govern Thisaims to educate token holders and make them better voters. Emphasis will be placed on specific governance proposals and relaying community governance discussions on forums and weekly calls. Governance is a coordination technology that has helped countries and companies build more than the sum of their parts. Blockchains are also a coordination technology, but for computers, not humans***.*** Govern Thiswill track the development of the melding of these two over the coming years. Like governance,Govern Thisis a work in progress. I would appreciate any feedback on format, topics covered or any other suggestions to make the newsletter better. Just hit reply. The first issue ofGovern Thisis below. Pleaseclick here to subscribe. Thanks for reading, Chris 📷 dxDAO aims to power DeFi protocols through decentralized governance Gnosis launched a long-awaited DEX last week with batched auctions for low-liquidity trade pairs. The front-end, Mesa.Eth.Link is owned and operated by dxDAO, a decentralized collective that hopes to power other DeFi protocols. While dYdX does not have any specific governance plans (yet), this tweet from dYdX founder Antonio Juliano is a common approach to governance. 📷Antonio Juliano @AntonioMJuliano3) 0x should focus less on governance in the short term. It’s way more important to first build something with a large amount of adoption that’s worth governing December 6th 2018 3 Retweets62 Likes The tweet at the end of 2018 was in response to 0x and its native token, ZRX. The project was popular but the token had no use case outside of governance. This governance strategy – build now, decentralize later – is widely accepted in the space and is perhaps best exemplified by the A16Z’s Jesse Walden’s post, “Progressive Decentralization: A Playbook for Building Crypto Applications”, which the A16Z-backed Compound has essentially implemented (more in the section below). dxDAO, on the other hand, maintains that decentralization must come at the beginning or else the core team and investors will have an outsized influence on the project in formal (token voting) or informal ways (dictators for life). Background dxDAO was launched in May 2019, spun out of a collaboration between Gnosis and DAOstack over managing the DutchX platform. dxDAO’s key governance design is separating financial rights to the DAO (DXD) from voting power over the DAO (Reputation). It used an Edgeware-style lock drop to distribute reputation to stakeholders in May of last year. Any user could lock up ETH or an accepted ERC-20 for a month and receive Reputation, which are voting rights in dxDAO, even though it is not a token and cannot be transferred. Over 400 unique Ethereum addresses participated in the distribution scheme. Gnosis went through a pretty extensive process in July 2019 to “step back” from its involvement in the DAO, and since then, the community and dxDAO have aligned behind a mission of “putting the ‘De’ in Decentralized Finance”. Following on last week’s launch of Mesa.ETH.Link, dxDAO is conducting a fundraiser or (“DAICO”?) to help fund its new slate of DeFi products, including a prediction market platform (Omen) and a privacy-centric DeFi dashboard (Mix). Project launch is typically when a project is most centralized. Execution is hard and direction and accountability are important. dxDAO’s approach will be an interesting counterexample to the “decentralize later” trend and may provide insight into new governance strategies. Click here for more information about the dxDAO fundraiser. Here’s what is on the dxDAO docket this week:
There are no explicit plans yet, but the widely held assumption is that the COMP distribution will be determined by the interest earned and paid by users on the protocol since its inception. This is a clever way that only incentivizes more use of the protocol and is hard to game because interests accrues over time. But the question still remains, what will the COMP community look like and what values will it espouse? Can emergent cultures arise out of Silicon Valley too? Here’s what is on the Compound docket this week:
Governance AMA with Compound CEO Robert Leshner - Robert answered a variety of questions on ETH2.0 (staking yield is of great interest), Chainlink (Compound’s oracle system is better), contentious forks (Compound would signal a preference on chain) and how Covid-19 changed his mind about remote work. They also announced…
Proposal: Add USDT Support – announced on the AMA, USDT was approved by Compound users in a poll last September but had yet to be included. The proposal to add the largest stablecoin in the world is the first test for the new governance portal. (Very) notably, the proposal does not allow USDT to be used as collateral, as Compound currently does with wBTC. It’s not clear if Compound wants to be in the largest stablecoin market or not and underscores the governance challenges of straddling both worlds.
Head of Community Rich started off with a new meme for governance: the path from intent to implementation, discussing how forums, polls and other initiatives are designed to capture the intent of the community, and then “empowered people” are tasked with implementing that, foreshadowing upcoming changes.
Half of the call was devoted to the addition of WBTC as collateral with representatives from WBTC, Bitgo and CoinList in attendance. CoinList’s WBTC announcement gives WBTC the type of liquidity needed for Maker’s auctions (“can redeem WBTC in less than 2 minutes and burn less than that”). Most of the discussion revolved around the circular loop from BTC->DAI in times of high volatility. While there was some concern that WBTC liquidity was dependent on acceptance as Maker collateral, most on the call seemed to support the addition. The strongest support seemed to come from the Maker Foundation’s market making team, who is reportedly the largest market maker for WBTC. There’s more in the Maker forum thread.
State of the peg – Vishesh’s overview (graphs can be seen here) showed that the peg had come down to $1.01x area but most of the discussion was around the debt ceiling. At the time of the call it was 4 million away from its 90m debt ceiling. Vishesh advocated for a more programmatic lifting of the debt ceiling. Update: Dai hit the 90m debt ceiling Friday evening ET. Should help the peg.
Single Collateral Dai shutdown – the process has begun. A poll passed with May 12 as the official SCD shutdown. Just yesterday, an executive just passed yesterday to make the MKR oracle fee-less, which will help with migration. Many in the community think the migration of debt from SCD will do more than enough to restore the peg. 13 MIPs and 2 sub proposals – Core to the new Maker governance process is the “Maker Improvement Proposals (MIPs), which are modeled off of BIPs (for Bitcoin) and EIPs (for Ethereum). The two sub-proposals are to appoint the Smart Contracts Team and assign Charles St. Louis as the MIP editor. The 13 MIPs are listed below:
By and large, the MIPs codify many of the informal Maker governance processes. There is currently a request for comments period (MIP forum) and there will be an informal poll on Monday, April 27 on whether to proceed with the 13 MIPs and 2 sub proposals. If it’s a “Yes”, than an executive for an official ratification vote would start on May 1 and lasts for 4 days. If it passes, the official governance cycle will begin and the rest of the MIPs will likely be approved from May 4 – 6. Other Governing Things
