Architektur

• Source: https://github.com/samerhijazi/studying/blob/main/sawtooth/sawtooth-start.yml

Key-Words

• Validator: checks and ensures that a transaction has a valid signature and directs it to the appropriate transaction processor
• REST-API:
• CLI: Command-Line-Interface
• TransactionProcessors: Applications that initiates smart contracts.
• Consensus: Each network participant waits a randomly-assigned amount of time. The first one to finish waiting becomes the producer of the next block.

Components

• Validator: @validator
• REST-API: @rest-api
• CLI: @cli
• TransactionProcessors: @settingTP, @intkeyTP
• Consensus: @devEngine (Devmode consensus engine); @engineA (PoET: Proof-of-Elapsed-Time)

Lify-Cycle

• Generating: Validator Keys (sawadm keygen) >>> @validator
• Generating: Transactor Keys (sawtooth keygen) >>> @cli
• Generating: Genesis-Batch (sawset genesis) >>> @validator
• Configuration: (path.toml, cli.toml, validator.toml) >>> @validator
• Configuration: (rest-api.toml) >>> @rest-api
• Generating: Genesis-Block (sawadm genesis) >>> @validator
• Starting: Validator (sawtooth-validator) >>> @validator
• Starting: rest-api (sawtooth-rest-api) >>> @rest-api
• Starting: settingsTP (settings-tp) >>> @settingsTP
• Starting: intkeyTP (intkey-tp-python) >>> @intkeyTP
• Starting: devEngine (devmode-engine-rust) >>> @devEngine

Explory

Contrary to how we start other blockchains, we do not start bootstrapping Hyperledger Sawtooth with the genesis block creation. We must begin by generating public and private keys for both our user and validator.
