Checkpoint finality verifier for Sui

Implementations

impl CheckpointVerifier

pub fn new() -> Self

Create a new checkpoint verifier with default configuration.

pub fn with_config(config: CheckpointConfig) -> Self

Create a new checkpoint verifier with custom configuration.

pub fn config(&self) -> &CheckpointConfig

Get the verifier configuration.

pub fn is_checkpoint_certified( &self, checkpoint_seq: u64, rpc: &dyn SuiRpc, ) -> SuiResult<CheckpointInfo>

Check if a checkpoint is certified.

In Sui, a checkpoint is certified when it receives signatures from 2f+1 validators. Once certified, the checkpoint cannot be reverted.

Arguments

• checkpoint_seq - The checkpoint sequence number to check
• rpc - RPC client for fetching checkpoint data

Returns

Ok(CheckpointInfo) with certification details, or Err on failure.

pub fn is_tx_finalized( &self, tx_checkpoint: u64, rpc: &dyn SuiRpc, ) -> SuiResult<bool>

Check if a transaction’s checkpoint is finalized.

Arguments

• tx_checkpoint - The checkpoint sequence number containing the transaction
• rpc - RPC client for fetching checkpoint data

pub fn latest_certified_checkpoint( &self, rpc: &dyn SuiRpc, ) -> SuiResult<Option<u64>>

Get the latest certified checkpoint.

Arguments

• rpc - RPC client for fetching checkpoint data

pub fn current_epoch(&self, rpc: &dyn SuiRpc) -> SuiResult<u64>

Get the current epoch from the network.

Arguments

• rpc - RPC client for fetching epoch info

pub fn is_epoch_passed( &self, expected_epoch: u64, rpc: &dyn SuiRpc, ) -> SuiResult<bool>

Verify that an epoch boundary has passed.

Arguments

• expected_epoch - The epoch we expect the network to be in
• rpc - RPC client for fetching current epoch
