# Summary
|
|
This is the algorthm used in Hyperledger Iroha.
|
|
|
|
# Extracts
|
|
|
|
1. A client forms a transaction with commands and signs it with their private key.
|
|
2. The client sends the transaction to a peer. The peer receives the transaction, performs stateless validation (i.e., verifies that it is not malformed), and relays it to the OS.
|
|
3. The OS generates a proposal and sends it to the peers. The proposal contains an ordered list of transactions that will be potentially added to the blockchain in this round.
|
|
4. The proposal is sent to the voting peers. Peers enter the collaboration phase, during which they exchange votes across the network and decide on a block. More details on the collaboration phase are provided in Section V.
|
|
5. The peer commits the block to their local block store.

# Notes
|
|
Consensus [7] should guarantee liveness of the system, security, and convergence (consistency) of data stored in the ledger
