Exactly, so an anti-DoS mechanism that would be sufficient for a non-mempool node would be also useful for small values in -maxmempool. I think a simple cache for transaction validations should be enough. Please, review a draft for that in the newest #6448. https://github.com/bitcoin/bitcoin/pull/6448 I would be happy to rebase it back to 0.11 and even 0.10. _______________________________________________ bitcoin-dev mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
