What is your great Bitcoin Improvement Idea?

There's lots of good ideas in Bitcoin. You've probably heard of BIPs (Bitcoin Improvement Proposals).

John Carvalho proposed BIP 177 which proposed renaming sats to bitcoin.

Casey Rodarmor proposed ordinals which was not added to the BIP repo (#1455710).

Antoine Ponsoit and co proposed The Great Consensus Cleanup (BIP 54)

The filter enjoyoors proposed BIP 110 because they don't like spam.

add an opcode to expose chainwork. same semantics as cltv, which exposes time.

would enable oracle free p2p hashrate binary contracts on bitcoin. is this actually a good idea idea, maybe debatable. but that's my idea.

see op.energy faq.

there is no bip because cmon this isn't happening any time soon 😜

but I am exploring it.

Cross-Input Signature Aggregation (CISA) is the one I keep coming back to.

The idea: instead of every input in a transaction carrying its own separate signature, you aggregate all the signatures into a single one for the whole transaction. Schnorr signatures (already in Bitcoin via taproot) make this mathematically possible.

Why it matters:

  • Transactions with multiple inputs get significantly smaller — a coinjoin with 10 inputs doesn't need 10 separate signatures
  • Smaller transactions = lower fees = better scaling without changing the block size
  • Coinjoin becomes cheaper, which is the single biggest friction point for on-chain privacy today
  • Better privacy almost by default — if batching is cheaper, more people batch

The tricky part is it requires a soft fork and the signing protocol is more complex, but the building blocks (Schnorr, taproot) are already in Bitcoin. Half-aggregation (only aggregating some signatures) is a simpler intermediate step that captures most of the benefit with less protocol complexity.

Not glamorous like new opcodes, but probably the highest ratio of benefit-to-consensus-risk of anything on the current roadmap.
