Add sequencer getblock command

[steezeburger]

We should probably have a get_block or GetBlock or w/e casing we’re using in go land.
The reason I ask is because I’m trying to understand how various stuff works, we emit Deposit events when a BridgeLock is sent to a bridge account, would be cool if I had the ability to:

• create a bridge account
• transfer to it
• look at block
• bridge lock to it
• look at block

And observe that there is a Deposit event

Where are the Deposit events stored in the SequencerBlock?

They are there they are in the transactions of the rollup_transactions those bytes are protobuf encoded RollupData. Which has a oneof of either Deposit or bytes of sequenced_data. They are bytes that need further decoded for merkle tree verification purposes.

GetSequencerBlock

Deposit

astria-geth GetDeposit()

SequencerBlock {
  ...
  RollupTransactions: []{
    {
      RollupId: 1
      Transactions: []{
        {<rollup serialized data>},
        {<sequencer serialized deposit},
      }
    }
  }
}

The Sequencer API gives you a SequencerBlock which contains RollupTransactions which has a repeated transactions field which is implicitly the serialized bytes for RollupData.

Using the Sequencer API to retrieve a block will not give you the RollupData object, but this is protobuf encoded, so it should be able to do something like the pseudo code:

for (per_rollup_txs in rollup_transactions) {
  for (txs in per_rollup_txs) {
    for (tx in txs) {
      RollupData data = tx.deserialize()
    }
  }
}
