Base58 to Bytes

Category: Data Conversion & Encoding · Node Type ID: converter-base58-to-bytes

Decodes Base58 string into raw byte array

Overview

Decodes a Base58 string back into a raw byte array (Uint8Array) using the selected alphabet (bitcoin or flickr). Leading 1 characters (in the Bitcoin alphabet) are restored as leading 0x00 bytes in the output buffer.

When to Use

Decoding Base58-encoded public keys, addresses, or identifiers into raw Bytes for signature verification or hashing.

Parameter Configuration

Parameter (ID)	Type & Default	Visibility Condition	Description & Options
Alphabet `alphabet`	`select` Default: `btc`	Always visible	Must match the Base58 alphabet used during encoding (`bitcoin` or `flickr`). `btc`: Bitcoin (BTC / IPFS) `flickr`: Flickr

Port I/O Specification

See Ports & Connections for general wiring rules, data type colors, and dynamic port creation.

Input Ports

Port Nature: Fixed Input Ports (1 total).

Port Name	Port ID	Data Type	Required	Visibility Condition	Description
`Base58 In`	`string`	`String`	Required	Always visible	Base58 string to decode.

Output Ports

Port Nature: Fixed Output Ports (1 total).

Port Name	Port ID	Data Type	Visibility Condition	Description
`Bytes Out`	`bytes`	`Bytes`	Always visible	Decoded raw byte array (`Uint8Array`).

Error Cases

When any of the following conditions occurs at runtime, this node transitions to an ERROR state and downstream nodes connected to its outputs do not execute.

Error Code	Default Engine Message	Trigger Condition
`INVALID_BASE58_CHAR`	Base58 string contains an invalid character	Raised when the input string contains characters not present in the selected Base58 alphabet.

Examples

Decoding a Base58 Public Key

Convert a Base58 address back into raw bytes.

Connect the Base58 string to Base58 String, set Alphabet to Bitcoin / IPFS, and wire Bytes to Ed25519 Verify.
