WHAT_SPEEDY_TRIAL_IS
Speedy Trial — at a glance
UPGRADES
Speedy Trial is a Bitcoin Improvement Proposal — a written specification of a change, a standard, or a process. A short activation window used for Taproot: miners signal within three months or activation aborts. BIPs are how Bitcoin evolves: anyone can write one, the community reviews it, wallets and nodes implement it if they like it, and adoption is the only signal that matters.
Why it exists
DESIGN
Speedy Trial exists because Bitcoin has no central authority — every change to wallet, miner, or node behaviour has to be coordinated through written specs that everyone can read, critique, and implement. The BIP process is how the community arrives at a single answer to a specific protocol question without anyone being in charge of dictating it.
HOW_IT_WORKS
Mechanism
HOW IT WORKS
BIP-? is implemented in source code that the proposer drafts alongside the text — typically against Bitcoin Core. Reviewers read both the spec and the code, and a BIP is only considered "real" once at least one independent implementation exists and is observed running on mainnet (or signet, for unactivated consensus changes).
1. Author drafts the proposal; posts a PR to bitcoin/bips or a mailing-list draft.
2. BIP editor assigns a number and merges the draft once it has a clear specification and motivation.
3. Community review on the bitcoin-dev mailing list, GitHub, IRC, conferences.
4. Reference implementation merged in Bitcoin Core or other software; alternative clients follow.
5. For consensus changes: activation parameters chosen, miners signal readiness, lock-in, eventual enforcement.
6. The BIP graduates to "final" once it's widely deployed and unlikely to change.

EXAMPLE
Full text : https://github.com/bitcoin/bips/blob/master/bip-XXXX.mediawiki
BIP repo : https://github.com/bitcoin/bips
Every BIP carries its own metadata header (Status, Type, Created, Layer, License)
before the abstract. Skim the abstract first, then jump to "Specification" for the
normative requirements, and "Reference Implementation" for the canonical code.
KEY_PROPERTIES
OPT-IN
No authority can force a BIP on anyone. Adoption depends entirely on whether the change is genuinely useful.
NUMBERED
Stable numeric reference — BIP-? means the same thing across every wallet, miner, and node that has read this spec.
NON-CONSENSUS
BIP-? is not a consensus rule — clients can implement it without coordinating with the network at large.
IMPLEMENTATION-DRIVEN
A BIP without a working implementation is just an idea. Real adoption requires code, testing, and time.
COMMON_PITFALLS
Things that catch people out
PITFALLS
- Don't confuse "draft" / "proposed" / "final" status — read the BIP header before relying on it in production.
- The BIP number is just an editorial counter — it doesn't imply correctness or stability. Always cross-reference with the latest bitcoin/bips repo.
