Crypto && Coffee 027
- 6 minsTechnology Recap:
Bitcoin:
- Thomas Voegtlin from Electrum, posted to the Bitcoin-Dev mailing list about creating transactions with stripped sizes (non-witness sizes) as small as 60 bytes. Bitcoin Core currently refuses to relay or mine transactions less than 82 bytes. The motivation for this rule is CVE-2017-12842 where an attacker can get a specially crafted 64 byte transaction confirmed into a block and use it to convince SPV clients that one or more arbitrary transactions have been confirmed.
Litecoin:
- David Burkett releases his May progress update on Mimblewimble (MW). His work has included implementing the AcceptBlock and ConnectBlock integration logic as well as initial work on the mempool so we could mine valid MW blocks which will allow him to test the end-to-end flow of MW transactions in a block.
