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. NewTribe Capital reached a strategic cooperation with the blockchain query node framework Subsquid: According to news on February 12, the blockchain venture capital fund NewTribe Capital reached a strategic cooperation with the Substrate query node framework Subsquid. It is reported that Subsquid is an open source framework for building a custom GraphQL API for the user's blockchain state history. [2022/2/12 9:47:44] 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 Pallets include: 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. Gate.io will provide support for SubDAO to bid for Polkadot parachain slots: According to official news, Polkadot infrastructure SubDAO has reached a strategic cooperation with Gate.io, and Gate.io will provide support for SubDAO to participate in the first round of Polkadot parachain slot auctions. At the same time, SubDAO will soon announce more platforms that support SubDAO slot auctions. It is reported that SubDAO is Polkadot's DAO infrastructure, which allows any decentralized organization to quickly create and manage DAOs, and provides tools and services such as blockchain-based electronic agreement signing, DAO socialization, and asset management. The founding team of SubDAO is composed of the former Technical Team Leader of IBM Group and Polkadot early developers and Polkadot community promoters. It has completed hundreds of projects including Huobi Ventures, OKEx Blockdream Fund and dozens of institutions, as well as Messari founder Ryan Selkis. million dollars in financing. [2021/11/2 21:19:08] 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 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. Decentralized data indexing tool SubQuery announced the roadmap: The decentralized data indexing tool SubQuery announced the roadmap, milestones include: 1. Internal test network; 2. Public test network; 3. Incentivize public test network and TGE; 4. SubQuery Foundation and liquidity mining; 5. Mainnet and online CEX; 6. Launch your own parachain and DAO. [2021/10/28 21:05:50] The Identity pallet allows users to publicly state 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. The Kusama network is currently using the Society pallet to build Kappa Sigma Mu (Body Blockchain Project), where members get tattooed to join and help take initiatives that bridge the gap between humans and machines. 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. News | Plasm Release Testnet Based on Plasma and Substrate Technology: Plasm Release Testnet, a scalable DApp platform based on Plasma and Substrate technology. Due to the use of Parity's Substrate technology, the Plasm network can be compatible with Polkadot after it is fully released. Sota Watanabe, co-founder of Plasm, said that Polkadot’s relay chain does not support smart contracts, so DApp developers participating in the Polkadot ecosystem need to choose parachains that support smart contracts, and have very high demand for scalability , so this is the positioning of Plasm. In addition, Plasm also utilizes Ethereum's two-layer network technology Plasma technology and Bitcoin's two-layer network technology Lightning Network (to be implemented in the future). The test network is the first phase of proof of concept (PoC-0) in the Plasm roadmap. In the PoC-3 phase, the second version of the test network will be launched and the design of tokens will be implemented. The main network is planned to be launched in February next year. [2019/11/11] In order to make off-chain data integration secure 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. Voice | Gavin Wood: Polkadot has successfully run a Substrate-based parallel chain: Dr. Gavin Wood, co-founder of Ethereum and founder of Polkadot and Parity, tweeted: Polkadot has successfully run a Substrate-based parallel chain, and Cumulus will soon later. [2019/10/23] Off-chain worker code 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. On the Substrate Developer Hub, you can dive into all the technical documentation, tutorials, and resources to get started.
