Upgrade Notice

• Upgrade node executable

  Effect: Fix bugs, and bring stability and performance improvements

  Operation: Stop the node service, upgrade the node executable to the current version, and restart the node service

  Notice: It is recommended to gradually replace the executable for a phased upgrade

  Versions supported before upgration: v3.0.0+

• Upgrade chain data version

  Effect: Can use the latest features of the current version

  Operation: First complete the upgrade of all node executables, then refer to the documentation to send a transaction to upgrade the chain data version to v3.2.2

  Notice: Be sure to back up all ledger data of the original node. If the operation is incorrect and the upgrade fails, you can roll back to the state before the upgrade using the original data.

  Versions supported before upgration: v3.0.0+

• Enable Experimental Features

  Effect: The experimental features can be controlled by the "feature" switch. All experimental features are disabled by default.

  Operation: Upgrade the node executable program and connect to the node through the console. Use the command "setSystemConfigByKey feature_name 1" to enable the corresponding experimental feature, except for RPBFT.

  Notice:

  • Feature operations are irreversible and cannot be closed once opened.
  • It is necessary to confirm that all executable program versions are the same before performing the feature enable operation.

Compatibility

Please refer to document for more details.

新架构

Air / Pro / Max ：满足不同的部署场景

• Air：传统的区块链架构，所有功能在一个区块链节点中（all-in-one），满足开发者和简单场景的部署需求
• Pro：网关 + RPC + 区块链节点，满足机构内外部环境隔离部署需求
• Max：网关 + RPC + 区块链节点（主备） + 多个交易执行器，满足追求高可用和极致的性能的需求

新机制

流程：流水线共识

以流水线的方式生成区块，提升性能

• 将区块生成过程拆分为四个阶段：打包，共识，执行，落盘
• 连续的区块在执行时以流水线的方式走过四个阶段（103在打包，102在共识，101在执行，100在落盘)
• 连续出块时，性能趋近于流水线中执行时间最长阶段的性能

执行：确定性多合约并行

实现合约间交易的并行执行与调度的机制

• 高效：不同合约的交易可并行执行，提高交易处理效率
• 易用：对开发者透明，自动进行交易并行执行与冲突处理
• 通用：支持EVM、WASM、Precompiled 或其它合约

存储：KeyPage

参考内存页的缓存机制实现高效的区块链存储

• 将key-value组织成页的方式存储
• 提升访存局部性，降低存储空间占用

继承与升级

• DAG并行执行：不再依赖基于并行编程框架，可根据solidity代码自动生成冲突参数，实现合约内交易的并行执行
• PBFT共识算法：立即一致的共识算法，实现交易秒级确认

• 功能：将合约地址与路径绑定，即可用路径调用合约

权限治理

开启后，对区块链的设置需进行多方投票允许

• 角色：治理者、管理员、用户
• 被控制的操作：部署合约、合约接口调用、系统参数设置等

WBC-Liquid：WeBankBlockchain-Liquid(简称WBC-Liquid)

不仅支持Soldity写合约，也支持用Rust写合约

• Liquid是基于Rust语言的智能合约编程语言
• 集成WASM运行环境，支持WBC-Liquid智能合约。
• WBC-Liquid智能合约支持智能分析冲突字段，自动开启DAG。

继承与升级

• Solidity：目前已支持至0.8.11版本
• CRUD：采用表结构存储数据，对业务开发更友好，3.0中封装了更易用的接口
• AMOP：链上信使协议，借助区块链的P2P网络实现信息传输，实现接入区块链的应用间的数据通信
• 落盘加密：区块链节点的私钥和数据加密存储于物理硬盘中，物理硬件丢失也无法解密
• 密码算法：内置群环签名等密码算法，可实现各种安全多方计算场景
• 更多请参考在线文档

兼容性

3.0版本与以往各版本数据和协议不兼容，Solidity合约源码兼容。如果要从2.0版本升级到3.0版本，需要做数据迁移。

更多，请参考版本与兼容性描述。

Please read our FISCO BCOS 3.x documentation.

New Architecture

Air / Pro / Max ：Support diffrent deployment scenarios.

• Air：Traditional blockchain architecture, all functions are in one blockchain node (all-in-one) to meet the deployment needs of developers and simple scenarios.
• Pro：Gateway + RPC + blockchain node. To meet the isolation deployment requirements of internal and external environments of the organization.
• Max：Gateway + RPC + blockchain nodes (active/standby) + multiple transaction executors. To meet the needs of high availability and extreme performance

New Mechanism

Pipeline Consensus

Generate blocks in a pipelined manner to improve performance.

• Split the block generation process into four stages: seal, consensus, execute, and commit.
• During block generation, all blocks pass through four stages in a pipelined manner. (103 for sealing, 102 for consensus, 101 for execution, and 100 for commitement)
• When blocks are continuously generated, the performance approaches the performance of the longest execution stage in the pipeline.

DMC: Deterministic Multi-Contract Parallelism

A mechanism for parallel execution and scheduling of transactions between contracts.

• Efficient: Transactions of different contracts can be executed in parallel.
• Ease of use: Transparent to developers, automatic parallel execution of transactions and handling conflict.
• Generic: Support EVM, WASM, Precompiled and other contracts.

KeyPage

Like the cache mechanism of memory pages to achieve more efficiency of blockchain storage.

• Organize key-value into pages to commit.
• Improve storage access locality and reduce storage space usage.

Inheritance and Upgrade

• DAG parallel execution
  • No longer rely on the parallel programming framework, can automatically generate conflict parameters according to the solidity code.
• PBFT Consensus Algorithm: An instantly consensus algorithm which can reach consensus in a second.
• For more information, please refer to our online documentation.

New Feature

BFS: Blockchain File System

Manage blockchain resources such as contracts, tables, etc. from the command line

• Commands: pwd, cd, ls, tree, mkdir, ln
• Usage: Bind the contract address to the path, so can use the path to call the contract.

Authority Governance

If turn on, multi-party voting is required during the settings of the blockchain

• Roles: Manager, Administrator, User.
• Controlled operations: deploying contracts, calling smart contract, setting system parameters, etc.

WBC-Liquid：WeBankBlockchain-Liquid

Not only supports writing contracts in Soldity, but also writing contracts in Rust

• Liquid is a smart contract programming language based on Rust language
• FISCO BCOS integrates the WASM runtime environment and support WBC-Liquid smart contracts.
• The WBC-Liquid smart contract supports intelligent analysis of conflict fields and automatically execute as DAG manner.

Inheritance and Upgrade

• Solidity: Currently supported up to version 0.8.11.
• CRUD: Use table structure to store data, which is more friendly to application development. We optimize the interface for easier-to-use in FISCO BCOS 3.0.
• AMOP: A off-chain message passing protocol, which can transfer off-chain message using P2P network of the blockchain nodes.
• Commit Encryption: The private key and data of the blockchain node are encrypted before storing in the physical hard disk, and cannot be decrypted even if the physical hardware gets lost.
• Cryptographic Algorithm: built-in group ring signature precompiled contract and other cryptographic algorithms, which can meet many security computing scenarios.
• For more information, please refer to the online documentation

Compatibility

The 3.0.0 version is incompatible with all older version's data and protocol, but compatible with the Solidity/WBC-Liquid contract source code. If you want to upgrade from version older version to 3.0.0, you need to do data migration.
