Deep Exploration of the sequencing of blockchain/integration consensus mechanisms Service (6)

One. Overview

1. Types of consensus algorithms

The goal of the Super Ledger application scenario is an enterprise-class blockchain platform, where network nodes are generally required to be added, so the super ledger does not support the standard POW algorithm.

2. Consensus mechanism of Hyperledger Fabric1.0

The super ledger divides the consensus into 3 stages, 6-1 of which are as follows:

(1) Endorsement of the transaction

The application selects the endorsement nodes according to the requirements of the endorsement policy and sends the transaction proposal (proposal) to the nodes that need to be executed. the endorsement node calls the chain code (CHAINCODE) to execute these trading proposals .

the execution of the trading process is simulated and does not actually submit the data to the ledger. After execution, the ESCC of the chain code of the transaction endorsement system is signed and endorsed by the simulation execution result .

Two. Multi-channel for data isolation

1. Initialization of the Sort service

2. Creation of channels

3. Update of the Channel

4. Join the Channel 5. Query for channels

Three. Pluggable Sorting Services
