As a stable 、 Efficient 、 Secure blockchain underlying platform ,FISCO BCOS On the one hand, we are committed to ensuring the stability of the system 、 Compatibility 、 Robustness 、 Ease of use , On the other hand, it focuses on improving the performance of the underlying platform of blockchain 、 Extensibility .

since FISCO BCOS v3.0 Start , The community adheres to open source 、 to open up 、 The principle of joint construction , Focusing on gathering the strength of the community will FISCO BCOS Build a more perfect blockchain underlying platform .

Now ,FISCO BCOS v3.0-rc4 Has been released , Of interest LTS The version is also in preparation , Under the active joint construction of community partners , I'll meet you soon , Coming soon .

this FISCO BCOS v3.0-rc4 Iteration launched FISCO BCOS Max edition , It aims to improve the scalability of the underlying platform of blockchain , So as to achieve the goal of supporting massive transactions on the chain .

IFLYTEK and Sun Yat sen University are both deeply involved in the development and co construction of this version .

IFLYTEK is v3.0-rc4 A group ring signature contract verification interface is developed 、 Realize the function of data falling disk encryption 、 Design and implement the blockchain monitoring system , Enrich the privacy computing power on the chain 、 While ensuring data security , It provides a layer of monitoring guarantee for the stability of the blockchain system .

The blockchain and intelligent finance research team of Sun Yat sen University jointly developed and implemented the conflict domain analysis function of smart contracts , It's solved FISCO BCOS v2.x In the version, developers need to manually identify the conflict domain , The pain point of parallel execution of smart contracts , It greatly simplifies the development threshold of parallel contracts .

Let's take a look FISCO BCOS v3.0-rc4 New features .

Max edition FISCO BCOS

In order to support massive transactions on the chain ,v3.0-rc4 Launched Max edition FISCO BCOS, Aims to provide Mass storage services 、 High performance scalable execution module 、 Highly available fault recovery mechanism .

Max edition FISCO BCOS The nodes of adopt distributed storage TiKV, The execution module becomes a service independently , Storage and execution can scale horizontally , And support automatic active and standby recovery .

Here's the picture , In order to achieve a highly available fault recovery mechanism ,Max edition FISCO BCOS Under the architecture , Introduce etcd Clusters are used to support multiple Max Node automatic active / standby switching .

Max Nodes mainly include BcosMaxNodeService、BcosExecutorService and TiKV colony ：

• BcosMaxNodeService: Including the trading pool module 、 Consensus module and synchronization module , Mainly responsible for packaging consensus transactions , The service can include multiple processes , Multiple processes are primary and standby to each other , adopt etcd The cluster chooses the master node .

• BcosExecutorService: Execution services , Multi service , Mainly responsible for executing transactions and blocks , A service can include multiple processes .

• TiKV: One Max The node needs to build a TiKV The cluster is responsible for storing 、 Access the ledger data in the node .

Max Node module

 FISCO BCOS v3.0-rc4 New characteristics

Besides ,FISCO BCOS v3.0-rc4 Still on security 、 Ease of use 、 Many optimizations have been made in terms of stability and performance , It mainly includes ：

Security 、 Ease of use

• newly added CRUD Contract interface , Simplify the threshold of blockchain application development

• Support group ring signature contract verification interface , Enrich the privacy computing power on the chain

• Support contract lifecycle management , Can be frozen 、 Unfreeze the contract

• Support data encryption

• Update the Authority Governance contract , Manage node roles 、 System configuration modification 、 Contract lifecycle management and other functions are incorporated into the governance framework

• Optimize Pro edition FISCO BCOS Chain building script , Support the configuration of organization dimension RPC、Gateway、BcosNodeService Etc

• Design and implement the intelligent contract conflict domain analysis function , Simplify the threshold of parallel contract development

Stability optimization

• be based on mtail + prometheus + grafana + ansiable Build a blockchain system monitoring system

• be based on Rip Protocol principle , Realize network forwarding function , Improve network robustness

Other performance optimizations

• introduce KeyPage Mechanism , Read at page granularity 、 Store status data , Optimize read storage performance

• Optimize DMC Performance of the execution framework , Support batch distribution transactions

• Optimize RPC and P2P Network processing performance of the module , The network performance can expand linearly with the number of network connections

Cross platform support

• Support linux aarch64 platform
