To describe multi-organizational decision making by a smart contract, an

infinite array of possibilities exist, where a smart contract developer takes an

existing business process that governs either the financial prices or delivery

conditions and expresses the procedure in a programming language.

Policy of endorsement

A policy of endorsement that applies to all of the smart contracts defined

within it is associated with every chaincode. In order for a transaction to be

declared valid, it indicates which organizations must sign a transaction

generated by a given smart contract in a blockchain network.

Validity of transactions

A smart contract upon execution in the blockchain network runs on a peer

node owned by an organization. To read and write the ledger, a set of input

parameters is taken by the contract and used in combination with its program

logic, that is, the transaction proposal. If the transaction is valid, the changes to

the world state are captured that contains a read-write set with both the states

that have been read and the new states that are to be written as the response to

the transaction proposal. When the smart contract is executed, the world state

is not updated, which may be noted.

Channels

In Hyperledger Fabric, simultaneous participation in multiple, separate

blockchain networks is allowed to an organization through channels. To j oin

multiple channels and participate in a network of networks is an efficient way

of sharing the infrastructure by an organization while maintaining data and

communications privacy. Channels are independent enough to help

organizations to separate their work traffic with different counterparties and
