Bitcoin Signet attack blocks demonstration

April 7, 2026r/Bitcoin

In r/Bitcoin, Bitcoin Core developers plan a Signet testnet demo of deliberately slow-to-verify attack blocks, inviting node runners to observe real-time validation behavior.

a handful of Bitcoin Core developers are going to be doing a demonstration of “attack blocks” designed to take an inordinate amount of time to verify on Signet.
The demonstration will take place at 10 AM EST (2 PM UTC).
Anyone who wishes to participate can run Bitcoin Core node on Signet and watch the blocks be mined and processed by their node in real-time.
