Bitcoin Core's standardness rules aim to mitigate DoS attacks and promote upgrades.
The Citrea bridge bypasses data storage limits using Taproot outputs for its transactions.
Proposals suggest removing OP_RETURN restrictions to prevent harmful practices in data storage.

Testnet4 aimed to improve upon Testnet3 but retained a problematic difficulty reset rule.

A proposed solution is removing the difficulty reset rule via a flag day hard fork on January 1, 2026.
