Transactions

A transaction is a signed request to execute work on the blockchain. The executable payload can be an ordered sequence of instructions, a contract call, IVM bytecode, or a proved IVM execution. See Smart Contracts for the current contract execution model.

All interactions in the blockchain are done via transactions.

All transactions, including rejected transactions, are stored in blocks.

For privacy-preserving asset movement, see Anonymous Transactions. Anonymous transactions use shielded asset notes, commitments, nullifiers, and zero-knowledge proofs instead of public account-to-account balance changes.

For proof evidence over selected transparent execution effects, see FastPQ. FastPQ consumes execution witnesses after normal transaction execution and builds deterministic proof batches for supported state transitions.

Here is an example of creating a new transaction with the Grant instruction. In this transaction, Mouse is granting Alice the specified role (role_id). Check the full example.

let grant_role = Grant::account_role(role_id, alice_id);
let grant_role_tx = TransactionBuilder::new(chain_id, mouse_id)
    .with_instructions([grant_role])
    .sign(mouse_private_key);
