What input does BLAKE2b take?

Hex bytes (0x optional). Output length is 1 to 64 bytes; 32 is the common choice.

Is Base58 here the same as Base58Check?

No. This is plain Base58 with no version byte or checksum, as used for Solana keys.

Yes. It only reads public data you paste. Nothing is stored or logged, and you never need a private key or seed phrase here.

BLAKE2b with any output length and optional personalization, Substrate's twox128, and plain Base58 encode/decode, in one place.

Try an example:BLAKE2b-256 of hello twox128(System)

BLAKE2b is used by Zcash, Polkadot, Cardano and others; the output length and personalization string change the result, so both are adjustable. twox128 is the xxHash variant Substrate uses to build storage keys from pallet and item names.

Base58 is the alphabet behind Bitcoin and Solana addresses, without the checksum. Use it to turn raw bytes into a Solana-style key or to see the bytes behind one.
