Before we merge, I want to circle back to this and a few other things with the data modeling. What's the lifetime of the spent nullifier map? How big is a SNR? An OOM seems somewhat unlikely but I don't totally understand the approach yet.

this is a good flag, still thinking through the proposed data structure.

the spentNullifiers map is a local variable that only lives for the duration of processing a single block in processBlock(). It isn’t a class field or stored anywhere long term. SNRs are stored in the spendable_notes indexeddb table using the saveSpendableNote() storage method, and the state payload is marked as spent by appending a "heightSpent" field in storage.

SNRs are ~700 bytes.

OK this seems totally fine, round it to 1KB, that's 1M SNRs. sgtm

after reviewing the code, Map<Nullifier, SpendableNoteRecord | SwapRecord> is actually the optimal and clever approach to minimize db fetches required to understand what subaccount a particular LP position is eventually associated with.

stepping through the code, prior to calling resolveNullifiers() , indexdb stores the successfully trial decrypted spendable notes in a table who's primary key is the commitment and secondary index is the nullifier. So in theory, you have all the information to know which SNR is associated with what commitment and nullifier directly in storage, but don't yet know which transaction that commitment is associated with, because we haven't processed and saved the transaction information at this stage of the block processor.

resolveNullifiers() will subsequently query any SNR / SwapRecord stored in indexeddb that match any nullifier in the incoming compact block, and the record <> nullifier pair are stored in the spentNullifiers map.

up until this point in the block processing, we know a few things:

  • which SNR / SwapRecord is associated with the user
  • what commitment + nullifier is associated with what SNR / SwapRecord
  • don't know which transaction is associated with the SNR / SwapRecord or commitment

then, if we found a commitment or nullifier relevant to the user in that block, we request all the transactions for that block height from the full node, and filter the specific transaction relevant to the user. This is where the original spentNullifiers map comes into play. We have a spentNullifiers map (Map<Nullifier, SpendableNoteRecord | SwapRecord>) and commitmentRecords map (Map<StateCommitment, SpendableNoteRecord | SwapRecord>), and once we know which commitment / nullifier inside the transaction's actions is associated with the user's commitment / nullifier (stored in those maps in memory), we know we transaction is the user's, and we return the transaction associated with it's relevant subacount by deriving the AddressIndex from the SNR itself.

After identifying the transaction, we have a special method called processTransactions that will identify the LP position relevant to the user and save it alongside the subaccount.

anyways, if we didn't originally have this map, once we knew which nullifier is associated with the user, we'd need to perform another db query to fetch the relevant SNR from the table, and subsequently derive the AddressIndex.

thanks for this great explanation, @TalDerei! This is exactly what the PR does in the smallest details
