Hi Jonas,

I’m working to get numbers based on both historical data and from fuzz tests but I’m in the middle of updating the code to match the doc, I should have it finished before the end of the week.

We estimate that 100 blocks is safe from reorg, that is the same policyfor spending coin base transactions, in the PR I add a compressrawtransaction RPC endpoint that has that limit built in and will warn the user that the TxIdis uncompresssed due to it not being old enough. That said I’ll add it into the doc in case anyone adds onto it.

Thanks for the feedback!-

Tom.
