Substrate 2.0 is here

With Substrate, the runtime is your blockchain canvas, providing you with maximum freedom to create and customize blockchains completely according to your application or business logic. In runtime, you can compose any state transition function with built-in database management, libp2p network, and fast and secure consensus protocol GRANDPA. Focus on your strengths by leveraging Substrate's modular design to use tried and tested libraries while building custom components that matter most. In late 2018, Polkadot co-founder Gavin Wood   demonstrated that Substrate 1.0 enables pluggable consensus and fork-free runtime upgrades, and now, with Substrate 2.0, builders can use the tried and tested framework to deploy the The desired blockchain. Substrate's modularity is part of its core design principles - you can replace many of the major components, from the network stack like the consensus and finality engines (Substrate comes with AURA, BABE, GRANDPA and a configurable PoW engine already built in), to the runtime development can be replaced. Runtime modules, or pallets, are prebuilt components that can be used to compose a Substrate runtime. Each pallet has its own logic, which can modify the characteristics and functions of the state transition function of the blockchain, so that basic functions and extended functions can be easily added. FRAME is a framework for developing Substrate pallets. FRAME makes it easier to find, select, and implement the right pallet for your custom blockchain, making it Substrate's default modular, customizable runtime development framework. Substrate 2.0 comes with a number of new pallets that will help you quickly and easily build and deploy a blockchain runtime with properties that are right for you and your network. SubDAO announced Middleware version 2.0, which will support the creation and management of multi-signatures and DAO organizations on Twitter: According to official news, SubDAO will release version 2.0 of the Twitter middleware, and the new version will iterate the latest features of the DApp Solidity version, mainly used on Twitter To create a Multi-sig multi-signature and manage DAO organization, the sponsor can issue 1155 agreement NFT as DAO token for DAO collection, and customize the release and circulation rules of DAO token. SubDAO is a DAO infrastructure protocol that helps manage digital assets through middleware, Multi-sig and other decentralized functions, and has been deployed on multiple mainnets such as Ethereum, BSC, Polygon, and Moonbeam. It is reported that SubDAO has received financing from Messari founder Ryan Selkis, Hypersphere, CMS Holdings, OKX Ventures, Huobi Ventures and other institutions. [2022/12/2 21:18:06] The number of pallets will continue to grow over time as Parity and independent teams develop and release their own Substrate-based blockchains. Substrate 2.0 comes with over 70 pallets to help you build blockchains. Now, it's published on crates.io, which lets you simplify package management with Rust's package manager, cargo. Some examples of Pallet include: BNB Chain announced the list of the fourth batch of projects shortlisted for the MVBIV incubation plan, and projects such as SubDAO were selected: On March 10th, BNB Chain’s official Twitter announced the list of the fourth batch of shortlisted projects for the MVBIV incubation plan. Cross-chain DAO protocol SubDAO, chain game association Cosmic Guild, GameFi project StarSharks, non-custodial on-chain trading market PearDAO, cross-chain NFT trading market GAT Network, decentralized trading platform Hashflow, and Metaverse streaming media platform Ceek, a total of seven projects were selected . These seven projects will receive a series of incubation support from the BNB Chain ecosystem. [2022/3/10 13:48:56] The Contracts pallet allows smart contracts to be deployed to a WebAssembly virtual machine, allowing contracts to be written in any language that compiles to Wasm, such as Rust, C++, and Go. BABE and GRANDPA are companion pallets for proof-of-stake networks that require fast, reliable block production and finality. Other methods of consensus that are compatible with Substrate include Aura (permission rotation and instant sealing). You can learn more about the BABE and GRANDPA consensus here. Democracy is a platform that implements on-chain voting mechanisms for fast, binding and transparent governance by stakeholders. The EVM is a pallet that replicates the functionality of the Ethereum Virtual Machine so that EVM applications can be quickly ported to the Substrate chain. Many existing chains are leveraging this pallet to integrate Solidity-based contracts, such as  Moonbeam and Plasm. The decentralized data indexing tool SubQuery will support the EVM beta versions of Moonbeam and Moonriver: On October 29, the decentralized data indexing tool SubQuery announced that it will support the EVM beta versions of Moonbeam and Moonriver, allowing developers of Polkadot and Ethereum to Seamlessly integrate Substrate and EVM data in one place, and use GraphQL to query this single source of truth. In addition, the filters introduced by SubQuery can filter non-contract transactions, transaction senders, contracts, and index log parameters, so developers can build a variety of projects that meet their specific data needs. [2021/10/29 6:19:17] The Treasury pallet provides a way to add funds to the treasury, which can be used to fund any activity the network wants to undertake. The pallet is currently live on Polkadot, Kusama, and other live blockchains built on Substrate. The Identity pallet allows users to publicly declare who owns certain accounts by providing account names and contact information. This is especially useful for validators on proof-of-stake networks. Account and key security is extremely important when handling large amounts of money. This is one of the main reasons for creating the Multisig pallet, which allows the use of one account to control different keys/devices. The Recovery pallet introduces a recovery mechanism for on-chain assets, especially useful for recovering lost keys in a user-friendly manner. Learn more about social recovery mechanics here. Polkadot Substrate framework parachains have integrated Chainlink Oracle data: According to official news, parachains based on Polkadot (DOT) Substrate framework can now integrate Chainlink (LINK) price Oracle data in the form of simple modules. The developers say this provides teams across the Polkadot ecosystem with a standardized, easily integrated oracle solution to support their DeFi applications. The new service starts as a module (or "pallet") of the Substrate blockchain framework ) form launch, which includes Polkadot, Kusama and other independent blockchains built on top of it. Various parachains can now integrate Chainlink's price oracle using a simple library. Parachain developers can choose whether to integrate Oracle data according to the situation. [2021/4/3 19:42:36] Kusama network is currently using the Society pallet to build Kappa Sigma Mu (human body blockchain project), in which , members join in through tattoos and help take initiatives that bridge the gap between man and machine. Off-chain workers are a new feature in Substrate 2.0 that allow you to securely integrate data onto your blockchain, ideal for Internet of Things (IoT) devices or through oracles ) for the actual data entry. SGB (SubGame) will be launched on the BiKi platform at 12:00 on March 12: According to the official announcement of BiKi, SGB (SubGame) will be listed on the BiKi platform at 12:00 on March 12 (GMT+8), and SGB/USDT will be open Trading pairs, and open deposit and withdrawal. SubGame is a game and payment module engine parachain for many developers to participate in Polkadot ecological construction. SubGame uses Subscript as the underlying language, follows the syntax of Javascript, and completes the packaging of the Substrate smart contract API and SDK in Assembly Script. Simply put, Subscript implements the ability to support any web developer to quickly deploy Polkadot's native smart contracts. [2021/3/11 18:35:29] In order to make off-chain data integration safer and more efficient, Substrate provides off-chain workers. Off-chain worker subsystems allow for longer-running and potentially non-deterministic tasks (e.g. web requests, encryption/decryption and signing of data, random number generation, CPU-intensive computations, enumeration/aggregation of on-chain data, etc.) to leverage on-chain data and access. An example is the "I'm online" pallet, which takes advantage of off-chain workers. In this way, validators in the proof-of-stake network who have not produced blocks can automatically send transactions on the chain to indicate that they are still available. This ensures that validators are available, so they should not be kicked or slashed for being offline. Code for off-chain workers is stored on-chain and has access to the on-chain environment, but is never executed as part of block processing. Off-chain workers can easily run the correct code and allow for longer running tasks without tying up the blockchain. However, on-chaincode allows validation mechanisms such as voting, averaging, and challenges to be implemented in the state transition functions of the blockchain on which it operates. Blockchain/oracle network designers and the nodes running on the network can determine who should do what, when, and the rewards and punishments for participants. Substrate 2.0 comes with a set of pallets that enable more efficient data integration for blockchains that rely on existing or real-world data. With Substrate 2.0, it's easier than ever to build custom, scalable blockchains that interoperate with the Polkadot ecosystem, all containing the business logic needed to achieve the team's design goals. Substrate's developer ecosystem also helps you get your blockchain production-ready with an ever-improving suite of developer tools, as well as a suite of benchmarking and monitoring solutions, as expected from a best-in-class commercial-grade software framework.
