firestore-tx-queue v1.0.0

Transaction Queue

This piece of code is used to use firestore as a non concurrent job queue for transactions that have to be submitted to the network.

We simply create a firestore table to store transactions, a transaction can be represented as the following:

{
    "type": "payment", // "payment" or "allocation"
    "destination": "5...",
    "amount_in_pico": "100000000", // Pico units of NODL to send
    "proof": "fdde..." // Allocations only, hex encoded proof / hash
}

We also add a field paid indicating if the transaction need to be executed or not. We also have a retry field specifying how many times a transaction should be retried. Unpaid transactions with no retries left are kept for analysis purposes.

Limitations

• This is a non concurrent queue: many components can add transactions to the queue but we only support one of them executing and fetching the transactions. In a blockchain context this is good enough as we don't really have concurrent transactions anyways.
