The body of a single account update.

Fields

public_key: CompressedPublicKey

The public key of the account that the update applies to.

update: PartyUpdate<'a>

The updates to apply to the account.

token_id: TokenID

The token ID held by the account that this update should apply to.

balance_change: SignedAmount

The change in balance to apply to the account. A Positive change increases the balance of the account; a Negative change decreases it.

increment_nonce: bool

Whether to increment the account’s nonce when applying this update.

events: &'a Events<'a>

The list of ‘events’ emitted by the snapp for this account, used to reveal auxiliary information that will not be directly stored within the snapp account. See crate::event for more details.

sequence_events: &'a SequenceEvents<'a>

The list of ‘sequence events’ emitted by the snapp for this account.

These events are accumulated in the order that a block producer selects the transactions, and are made available via a cryptographic commitment stored in the sequence_event::SequenceState data structure. A ‘supervisor’ or ‘roll-up’ rule in the snapp smart contract may use this data to apply updates in a deterministic order when there otherwise might be data races.

call_data: CallData

The opaque ‘call data’

call_depth: u8

The ‘depth’ into the call stack, used to compute the crate::call_stack for the transaction. This depth must always be > 0 and may only increase by 1, but may decrease by any amount. See crate::call_stack for more.

protocol_state_condition: ProtocolStateCondition

The condition that must be satisfied by the procotol state of the most recent block in order for this update to be accepted.

account_condition: Account

The condition that must be satisfied by this account in order for this update to be accepted.

use_full_commitment: bool

Whether to use the hash of the full transaction – including the fee payer – in the signature. If false, only the non-fee-payer updates are included in the hash, and this party must increment its nonce to prevent replay attacks.
