This guide explains BIP 374 Discrete Log Equality Proofs in plain English. It covers the problem behind the BIP, why it matters and whether the proposal is part of Bitcoin today.
TL;DR
- What it is: BIP 374 is a Draft application-layer specification for 64-byte zero-knowledge discrete-log equality proofs on secp256k1. A prover show that two public relationships use the same hidden scalar without revealing it.
- Why it matters: BIP 374 supplies a compact proof for one precise equality of discrete logarithms. Safe use depends on exact transcript construction, strict input validation and treating proof success as one component of a larger transaction-authorisation decision.
- Current position: BIP 374 is a Draft application-layer specification for 64-byte zero-knowledge discrete-log equality proofs on secp256k1.
BIP 374 Discrete Log Equality Proofs in simple English
BIP 374 Discrete Log Equality Proofs: A valid DLEQ proof can show an ECDH share uses the input secret, but it does not independently verify transaction amounts, recipients or all signer policy.
Simple example
A node operator is checking BIP 374 Discrete Log Equality Proofs. BIP 374 is Draft, Specification, version 0.2.0 at the Applications layer. Their hash forms challenge e and response s combines nonce and secret.
Key terms in plain English
- BIP:
- Bitcoin Improvement Proposal: a document describing a proposed rule, standard or process. Its status must be checked separately.
- Node:
- A computer running Bitcoin software that checks data and communicates with other peers.
Status
BIP 374 is Draft, Specification, version 0.2.0 at the Applications layer. Implementations must pin the exact transcript and encoding rules.
Statement
For public points A, B, C and generator G, the prover knows scalar a such that A equals a times G and C equals a times B.
Proof shape
A nonce scalar creates two commitments. Their hash forms challenge e and response s combines nonce and secret; the encoded proof contains the challenge and response in 64 bytes.
How specialists test it
Developers test the proposal with made-up data on an isolated test network. They check normal cases and deliberately invalid cases. Different implementations should reach the same result before anyone relies on the proposal.
Randomness and messages
Generation takes 32 bytes of auxiliary random data and can bind an optional 32-byte message. Domain separation and deterministic handling must match the specification exactly.
Silent Payments
A valid DLEQ proof can show an ECDH share uses the input secret, but it does not independently verify transaction amounts, recipients or all signer policy.
