Aiden McClelland proposed a new BIP for a modular mempool/relay policy.

He's developing it using QuickJS, facing challenges due to a C++ hiatus.

The proposal aims to unify Bitcoin community relay policy disagreements.

Brandon Black proposes a Bitcoin soft fork to limit ScriptPubkey size for security reasons.

The rule affects a small fraction of outpoints, aiming to improve scalability and performance.

The proposal also anticipates challenges but invites community feedback for balanced innovation.

AdamISZ explores embedding data in Schnorr signatures' tuples, questioning the security without revealing private keys.

Concluding data embedding compromises private key secrecy, challenging the security of blockchain UTXO sets.

Invites critique on his findings, directing readers to his research on GitHub for further discussion.

Bitcoin nodes and miners have adopted new mempool policies, including full RBF and spam filters.

Compact block relay significantly reduces block propagation times, enhancing network efficiency.

Solutions like weak blocks and template sharing improve network robustness and transaction privacy.

Bitcoin's fee estimation process is complex and uncertain due to unpredictable miner actions.

Efforts to standardize mempools for predictable fee estimation could undermine Bitcoin's decentralization.

The focus should shift to broader network heuristics, embracing inherent transaction uncertainties and variabilities.

The study exposes Bitcoin network vulnerabilities, showing eclipse attacks via BGP hijacking are feasible.

Attackers manipulate BGP routes to control Bitcoin traffic, enabling potential financial abuses.

Proposed mitigations include peer rotation, dynamic port negotiation, and route-aware peer selection in Bitcoin Core.
