go-sequencing

go-sequencing defines a generic sequencing interface for modular blockchains

Sequencing Interface

Method	Params	Return
`SubmitRollupTransaction`	`context.Context`, `rollupId RollupId`, `tx Tx`	`error`
`GetNextBatch`	`context.Context`, `lastBatchHash Hash`	`batch Batch`, `timestamp Time` `error`
`VerifyBatch`	`context.Context`, `batchHash Hash`	`success bool`, `error`

Note: Batch is []Tx and Tx is []byte. Also Hash and RollupId are []byte.

Implementations

The following implementations are available:

centralized-sequencer implements a centralized sequencer that posts rollup transactions to Celestia DA.
astria-sequencer implements a Astria sequencer middleware that connects to Astria shared sequencer.

In addition the following helper implementations are available:

DummySequencer implements a Mock sequencer useful for testing.
Proxy implements a proxy server that forwards requests to a gRPC server. The proxy client can be used directly to interact with the sequencer service.
