PSA: Bitcoin network under attack

[Luke Dashjr]

The Bitcoin network is under attack, and block production has slowed
significantly.

The community is preparing mitigations to resolve the situation. In the
meantime, attackers are spreading misinformation and advising users to
downgrade or switch to insecure node software.

Users are strongly advised not to downgrade or switch to software that
weakens Bitcoin's consensus protections. Doing so may compromise your
security and expose you to false confirmations from blocks that are
invalid under Bitcoin's consensus rules.

If you have already downgraded, upgrade to the latest version of Bitcoin
Knots. Knots will attempt to repair the resulting chain state and return
your node to the valid chain.

Miners who restart their nodes may need to add the following to
bitcoin.conf:

maxtipage=2592000

Another announcement will be published as soon as a mitigation is ready.

A new proof-of-work algorithm will be chosen on August 11th at 14:00 UTC
in the Discord #strategy channel, based on a deterministic random choice
between candidates. A relevant hash for that proof-of-fairness:
