Components
- MSP (Memberahip Service Provider)
- Leger: Record of all state transitions, result of chaincode invocations "transactions".One Leger per Channel. Ledger consists of (world state/blockchain)
- Channel:
- Smart-Contract: defines business logic
- Chaincode: SmartContracts packaged in Chaincode then deployed to blockchain-network.
- Blockchain-Network:
- Ordering-Service:
Begriffe
- Client Application: interact with blockchain network on behalf of useres.
- Wallet: contains a sset of user identities to connects to a channel
- Gateway: manges the network interactions on behalf of application.
Chaincode Deployment
- Package the chaincode.
- Install the chaincode package.
- Approval the chaincode definition.
- Commit the chaincode defintion to a channel.
Chaincode Upgrade
- Repackage the new chaincode.
- Install the new chaincode package.
- Approval the new chaincode definition.
- Commit the new chaincode defintion to a channel.
