Ethereum Classic is an open, decentralized, and permissionless public blockchain, that aims to fulfill the original promise of Ethereum, as a platform where smart contracts are free from third-party interference. ETC prioritizes trust-minimization, network security, and integrity. All network upgrades are non-contentious with the aim to fix critical issues or to add value with newly proposed features; never to create new tokens, or to bail out flawed smart contracts and their interest groups.
A global multi-asset cross-chain social and financial operating system: broaden ecosystem, engage community, bring in developers, create decentralized applications and expand users and network via SPOs
Native Custom Tokens in the Extended UTXO Model : User-defined tokens—both fungible ERC-20 and non-fungible ERC-721 tokens—are central to the majority of contracts deployed on Ethereum. User-defined tokens arenon-native on Ethereum; i.e., they are not directly supported by the ledger, but require custom code. This makes them unnecessarily inefficient, expensive, and complex. On Ethereum, ERC-20 and ERC-721 tokens are fundamentally different from the native crypto-currency, Ether, in that their creation and use always involves user-defined custom code — they are not directly supported by the underlying ledger, and hence are non-native. This makes them unnecessarily inefficient, expensive, and complex. Although the ledger already includes facilities to manage and maintain a currency, this functionality is replicated in interpreted user-level code,which is inherently less efficient. Moreover, the execution of user-code needs to be paid for (in gas), which leads to significant costs. Finally, the ERC-20 and ERC-721 token code gets replicated and adapted, instead of being part of the system, which complicates the creation and use of tokens and leaves room for human error... The alternative to user-level token code is a ledger that supports native tokens. In other words, a ledger that directly supports (1) the creation of new user-defined token or asset types, (2) the forging of those tokens, and (3) the transfer of custom token ownership between multiple participants.
UTXOma: UTXO with Multi-Asset Support : A prominent use case of Ethereum smart contracts is the creation of a wide range of user-defined tokens or assets by way of smart contracts. User-defined assets are non-native on Ethereum; i.e., they are not directly supported by the ledger, but require repetitive custom code. This makes them unnecessarily inefficient, expensive, and complex. It also makes them insecure as numerous incidents on Ethereum have demonstrated .
Make summaries of research papers for devs/users and videos from Shelley summit, put them on iohk.io/blog (just like you did for Hydraand Ourobors)
Clean up github repositories, docs, and avoid information duplication and outdated info to make it easy for learning and also for accountability
Explain clearly and transparently to the devs (current and future) what's IOHK/Emurgo building right now to avoid overlaps. For example, I just watched Project Atlas video again where it is stated that this is gonna be a "DApps store" while Charles clearly stated during his AMAs that he sees Daedalus as a DApps store:
With Atlas all users can:
Explore the blockchain
Cast ballots and vote.
Interact with the light wallet.
I recommend to watch video on Goguen (see below) because it tells you basically what kind of devs are they looking for, just skip from slide to slide to speed up the process. "The key elements of Goguen and the high-level deployment plan for the rest of 2020. Goguen represents the next major roll out of functionality for the Cardano ecosystem, bringing multi-asset standards and smart contracts. Shelley is laying the ground work to establish a robust, decentralized network, powered by stake pools and delegation. Targeting Q4 2020, Goguen will start to empower developers and app builders to create further value and utility on Cardano, to drive further adoption. Our bespoke languages Plutus and Marlowe make it easy to create secure smart contracts, without extensive blockchain knowledge. Goguen will enable you to:
Build decentralized applications, smart contracts and new businesses
Define, forge, and transfer new assets on the Cardano blockchain
This is basically a long TL;DR version ;)! It's important to see what others are doing (like Ethereum), what's missing on our side, what community is thinking and how to engage them and how to get more people into our ecosystem. So, today, if you ask me: "can you easily start building on Cardano today"? The answer is definitely maybe. Anyway, let me know your comments or your TL;DR version :-)!
The Gods Unchained DeFi Challenge – ETH prizes for the top 5 ideas!
You! Yes, you! We want you to open that big brain and share your ideas around Gods Unchained assets, DeFi and the wider crypto space! Submit your entry before September 26th, 2020 for your chance to win a slice of $3,000 USD in ETH alongside Genesis Chests. We’re constantly looking for new ways to give more utility to our in-game assets and thus power to the users that wield them – it’s why Gods Unchained exists. We’ve got plenty in the works in this space – with a new season and our game-changing exchange on the way – but what better way to put the power in your hands than to hear the interesting ideas you have around blockchain assets and the Ethereum ecosystem (and maybe even have some funded in the future 😉)? Gods Unchained is built to change the way in-game assets are viewed forever – a huge goal, sure – but your input could help bring this closer to reality.
We’re looking for creative ways for Gods Unchained items to be used in the DeFi or wider crypto space. The Ethereum network is constantly presenting exciting new ways to use assets, and we’re interested in how you’d use Gods Unchained assets to capitalize on the growing potential of DeFi. We’re not looking for fully laid out plans, simply proposals of what you think would work, be cool, or add to the current Ethereum ecosystem. Your proposal can be deep and technical (if that’s how you work) or simply a great idea written down in 1–2 pages that unlocks the blockchain’s full potential. What we’d like to see from your proposal is a clarity around the following:
What’s your idea?
What problem is it solving?
Why is your idea valuable?
How would it work? (To put it another way: how do you think it might work? Broad terms are fine, no need to go full white paper on us).
Submissions will be judged based on their potential value for Gods Unchained and our community, as well as on their originality, and feasibility.
Challenge Champion: $1,000 USD worth of ETH + 2 x Genesis Legendary Chests (1 available). This goes to the best entry to emerge from the challenge. There can only be one champ, and that champ could be you!
Big-Brain Bonus Prizes: $500 worth of ETH + 1 x Genesis Rare Chest (4 available). This is for those ideas that are so. damn. good. But just fall short of being the champ. All big-brain entries deserve a prize, but only the top four can get them.
This competition will be judged by an internal panel of Immutable judges led by our Chief Technology Officer: Alex Connolly.
How to Enter:
Entry is a two step process:
Publish your proposal in a public forum online. We suggest creating your own thread in GodsUnchained.
HOT TIP: Given you can make amendments up until the cutoff, we'd recommend hustling feedback from other users to increase your chances of being chosen. Many brains make light work... uh, that’s a saying, right?
To enter this competition, you will need to submit a proposal on potential tools and applications which utilize Gods Unchained assets, related to DeFi or the wider crypto space.
You are welcome to submit more than one proposal.
Your proposal can be deep and technical, or just a great idea using the blockchain to its fullest potential!
You do not have to build the tool, but you can choose to if you wish.
The Streamr Network transports the real-time data,
The Streamr Core app is used to build and manage the DU contract, and,
The Streamr Marketplace monetises the data.
How to start a Data Union? — Here are the four steps:
Define the sort of data you’ll be streaming to your DU.
Deploy the DU contract on Ethereum.
Integrate your end user app.
Publish the DU on the marketplace.
I will briefly explain these steps, and if you prefer, you can also get to know the process by watching me create a DU in the screencast series, or by reading the DU docs. The accompanying demonstration GitHub repo of example code can also be found here.
1. Define the sort of data you’ll be streaming to your DU
As the DU creator you’ll first need to decide what sort of data will be included into the DU and how to model that data into streams. A firehose approach is typical and we have some general advice on that topic in the streams section of the docs.
Using one of Streamr’s client libraries is highly recommended. The essential functionality such as member balance checks and member withdrawals are wrapped in easy to use library method calls.
4. Publish the DU on the marketplace
If you’ve gotten this far, this step is a breeze. It’s a one-click publish Ethereum transaction to have your DU available for purchase on the Marketplace. How to Deploy a Data Union Part two (video too long for Reddit) How to integrate the Data Union contract into an existing application 🎉 Congrats! You’re all set. 🎉 The Docs go much deeper into the implementation details and we encourage you to reach out on the developer forums to share your experience with the platform. Originally published by Matthew Fontana atblog.streamr.networkon September 1, 2020.
Data Unions 2.0 smart contracts are now ready and undergoing a third-party security audit. Remaining work consists of loose ends, such as the SDKs and Core application, as well as creating an upgrade path for existing DUs.
Data Unions public beta running smoothly. Incremental improvements were made in preparation for the official launch.
Started work on the Network Explorer, which shows the real-time structure and stats of the Streamr Network.
Started work on human-readable, hierarchical, globally unique stream IDs with namespaces based on ENS, for example streamr.eth/demos/tram data.
Storage rewrite complete, now setting up the new storage cluster in production. Will fix resend problems and prepare for opening up and decentralizing the storage market.
Token economics research with BlockScience continues in Phase 2, working on simple cadCAD models.
End-to-end encryption key exchange ready in Java SDK, while JS SDK is still WIP.
Buyer whitelisting feature added to the Marketplace.
Releasing the Network whitepaper marks the completion of our academic research phase of the current Network milestone. This research is especially important to the Streamr project’s enterprise adoption track, and focused on the latency and scalability of the network, battle-tested with messages propagated through real-world data centres around the world. The key findings were:
The upper limit of message latency is roughly around 150–350ms globally, depending on network size
Message latency is predictable
The relationship between network size and latency is logarithmic.
These findings are impressive! Not only do they show that the Network is already on par with centralized message brokers in terms of speed, they also give us great confidence that the fully decentralized network can scale without introducing significant message propagation latency. We invite you to read the full paper to learn more.
While the release of the Network whitepaper has been a long-term side project for the Network team, development of the Network continues to accelerate. As real-time message delivery is the primary function of the Network, so far we haven’t focused much on decentralizing the storage of historical messages. However, as the whole Network is heading towards decentralization, so is the storage functionality. The long-term goal regarding storage is that anyone will be able to join in and a storage node. Stream owners will be able to hire one or more of these independent storage nodes to store the historical data in their streams. The completion of the storage rewrite is another big step towards full decentralization.
Token economics research
The token economics research track with BlockScience has proceeded to Phase 2. In Phase 1, mathematical formulations of the actors, actions, and agreements in the Network were created. In the current Phase 2, the simulation code is being written for the first time. The simulations leverage the open source cadCAD framework developed by BlockScience. The models developed in Phase 2 are simple toy models, the purpose of which is to play around with the primitives defined in Phase 1 and verify that they are implemented correctly. In Phase 3, the first realistic models of the Streamr Network economy will be implemented.
Data Unions upgrade
On the Data Unions front, development of the 2.0 architecture is progressing well and the smart contracts are being security audited at the moment. Robustness and security have been the key drivers for this upgrade, and while 1.0 architecture is running smoothly, we need to be forward-thinking and prepare for the kind of scale and growth we expect to see in the future. Data Unions 2.0 will be the first big upgrade after the launch of the current architecture. Data Unions that are created with the current architecture will be upgradable to the Data Unions 2.0 architecture once available. We look forward to describing the upgrade in detail in a future blog post.
More control over your data
We released a heavily requested feature on the Marketplace — buyer whitelisting. This feature allows data product owners and Data Union admins to be in control of who can purchase and gain access to the product’s data. These features are useful in growing enterprise adoption of the Marketplace, because in B2B sales it’s often required that the transacting parties identify each other and perhaps sign traditional agreements.
Deprecations and breaking changes
A number of API endpoints need to be retired and replaced to be compatible with our vision of decentralization. This section summarises deprecated features and upcoming breaking changes. Items marked ‘Date TBD’ will be happening in the medium term, but a date has not yet been set.
The API endpoints for explicitly deleting data will be removed on the next update, because they are rarely used and are not compatible with decentralized storage. Going forward, storage nodes will expire old data based on the data retention period set on the stream.
The API endpoints to upload CSV files to streams will be removed in the next update, because the feature is rarely used and the centralized backend is unable to sign the data on behalf of the user. Storing historical messages to streams can be done by publishing the messages to streams normally.
(Date TBD): Support for email/password authentication will be dropped. Users need to connect an Ethereum wallet to their Streamr user unless they’ve already done so. As part of our progress towards decentralization, we will end support for authenticating based on centralized secrets such as passwords. Going forward, authenticating with cryptographic keys/wallets will be the only supported method of authentication.
(Date TBD): Support for API keys will be dropped. Applications integrating to the API should authenticate with the Ethereum key-based challenge-response protocol instead of API keys. As part of our progress towards decentralization, we will eventually end support for authenticating based on centralized secrets such as API keys. Going forward, authenticating with cryptographic keys/wallets will be the only supported method of authentication.
(Date TBD): Support for unsigned data will be dropped. Unsigned data on the Network is not compatible with the goal of decentralization, because malicious nodes can tamper with data that is not signed. As the Streamr Network will be ready to start decentralizing at the next major milestone (Brubeck), support for unsigned data will be ceased as part of the progress towards that milestone. Users should upgrade old client library versions to newer versions that support data signing, and use Ethereum key-based authentication (see above).
Thanks for reading! If you’re a developer interested in contributing to the Streamr ecosystem, consider applying to the Community Fund for financial backing to fast track your plans. Originally published by Matthew atblog.streamr.networkon September 15, 2020.
Once a year, the ENS team invites community members to an “unconference style” workshop, in which we discuss the current state and future direction of the project. Previously we’ve held this in London and Osaka, but this year’s workshop will be held virtually. We put out a call for participation about a month ago and just announced the date as September 29th 12noon US eastern time. To keep the discussions high quality, we ask those who wish to participate to apply. We’d love to see you there!
Both the ENS homepage and manager app are now available in 10 languages: English, Chinese, Japanese, German, Spanish, French, Korean, Polish, Russian, and Vietnamese. A big thanks to our volunteer translators! ENS is for everyone, so we’d like to have the ENS manager app and homepage in many languages to make it as accessible as possible. If you are a native speaker of another language and are interested in contributing, see the last section of our blog post on the subject.
Reclaim old deposits
If you registered a .ETH name sometime between May 2017 and May 2019 using the old auction system, you may have an unclaimed deposit. The ability to get back your old deposit has always been possible in our manager app, but to make it even easier we’ve made a standalone app where you can quickly check to see if you have any outstanding deposits and reclaim them.
