Encoding & Hashing Reference

This page collects small protocol references that are useful for integrators and indexers.

Address format

Dusk wallet addresses are Base58-encoded bytes of compressed public keys.

Address type	Underlying key(s)	Encoding
Moonlight (public)	1x `BLS12-381 G2` compressed (96 B)	`Base58`
Phoenix (shielded)	2x `Jubjub` points (`A`, `B`) compressed (2 x 32 B)	`Base58`

If you are building in Rust, the most reliable way to validate/parse addresses is to use rusk_wallet::Address::from_str() (it performs Base58 decoding, decompression, and structural checks).

Hashing algorithms

High-level map of what hashes are used for what (internal details live in rusk):

SHA3-256
- Block hashes, Merkle roots, and various consensus-related IDs.
BLAKE3
- Contract bytecode hash and contract event bloom filters.
BLAKE2b
- Contract IDs.
- Transaction IDs and hash_to_scalar-style hashing (hashing bytes, then mapping into a BLS scalar).
SHA2-256
- Integrity checks and some key-derivation primitives in the wallet stack.
