When we're notified that a tx has been confirmed, we: - ask bitcoind for a "txout" proof i.e a proof that the tx was included in a block - verify this proof - verify the proof of work of the block in which it was published and its descendants by checking that the block hash matches the block difficulty and (only on mainnet) that the diffculty is above a given target

We can use the tx position that we compute when we verify the inclusion proof instead of explicitly asking Bitcoin Core for it. We also check that the id of the tx that is returned match what we asked for, and add min-difficulty checks for regtest and testnet.
All blocks now are BIP34 compliant commit to their height in the sig script of their coinbase tx.
