BIP 54 Compatible Blocks

Introduction

Mara Pool mined their first BIP 54 compatible block : 940,548

What is The Consensus Clean up (BIP-54)?

The BIP proposes new consensus rules in order to fix the timewarp attack, reduce the worst case block validation time, prevent Merkle tree weaknesses, and avoid duplicate transactions without bip-0030 validation.

Changes:

1. Timestamp constraints at difficulty boundaries
2. 2500 sigops limit per transaction
3. Ban on 64-byte transactions
4. Coinbase nLockTime + nSequence constraints

Rare(-ish) 2 block reorg

https://bnoc.xyz/t/two-block-reorg-at-height-941880/97

"Per the stale-block repo, previous known two block stale chains:

788687 / 788686 - 2023-05-08 ; 153k blocks ago
656478 / 656477 - 2020-11-12 ; 132k blocks earlier
358999 / 358998 - 2015-06-02 ; 300k blocks earlier
261199 / 261198 - 2013-10-02 ; 98k blocks earlier
So perhaps every ~3 years or 150k blocks?"
