Detailed Description

class sgns::crypto::bip39::EntropyAccumulator;

Accumulates entropy tokens and exposes entropy + checksum.

Used to assemble mnemonic-derived entropy and validate its checksum.

Public Functions Documentation

function create

static outcome::result< EntropyAccumulator > create(
    size_t words_count
)
