Utility methods to create Ethereum Trie hashes
Available methods
trieRoot
Creates a trie hash from the supplied pairs.
trieRoot (pairs: Trie$Pairs): Uint8Array
From an Array<{k: Uint8Array, v: Uint8Array}> input, calculate the triehash and return the result as a Uint8Array.
import { u8aFromString } from '@polkadot/util';
import { trieRoot } from '@polkadot/util-triehash';
trieRoot([{
k: u8aFromString('A'),
v: u8aFromString('aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa')
}]) // => 0xd23786fb4a010da3ce639d66d5e904a11dbc02746d1ce25029e53290cabf28ab
trieRootOrdered
Creates a trie hash from the supplied values.
trieRootOrdered (values: Array<Uint8Array>): Uint8Array
From an Array<Uint8Array> input, calculate the ordered triehash and return the result as a Uint8Array.
import { u8aFromString } from '@polkadot/util';
import { trieRootOrdered } from '@polkadot/util-triehash';
trieRootOrdered([
u8aFromString('doe'),
u8aFromString('reindeer')
]) // => 0xe766d5d51b89dc39d981b41bda63248d7abce4f0225eefd023792a540bcffee3
