A big thank you to the HRF who proactively and quietly donated $20,000 USD to Bitcoin Optech for expenses related to the Optech newsletter and podcast 🧡

I get the impression that this is pretty common for Optech readers. Would some periodic less-technical “Optech decoded” or “Optech translated” summary be helpful?

Gloria Zhao, Niklas Gögge, and b10c discuss 3 recently announced Bitcoin Core vulnerabilities: - DoS vulnerability in headers sync - DoS vulnerability in inventory send queue - Crash vulnerability in compact block relay High severity: An attacker could provide a peer with a chain of low-difficulty headers, which could be used to remotely crash the node. Medium severity: Increased network activity affected block and transaction propagation and dropped connections. High severity: An attacker could remotely crash Bitcoin Core nodes by triggering an assertion in the blocktxn message handling logic.

What is Brink up to? We published a 23pg report on what engineers are working on in 2024 and got done in 2023. I hope the report is informative and transparently showcases the important work Brink is funding and our engineers are executing on.
