It is the Base58Check encoding of the version byte 0 and the 20-byte RIPEMD-160 hash of the SHA-256 hash of a public key, so it always starts with 1. Most such addresses have 33 or 34 characters; each leading zero byte of the hash adds a 1 and makes the address shorter. Testnet P2PKH addresses start with m or n and are not matched. - Parent datatype: `crypto_address` - Personal data (PII): no - Categories: Cryptocurrency (cryptocurrency) - Countries: global - Languages: Common to most languages (common) - Classification: identifier ## Detection Regular expression (Python `re`): ``` ^1[1-9A-HJ-NP-Za-km-z]{25,33}$ ``` Check digit algorithm: `base58check` ## Examples - `1PMycacnJaSqwwJqjawXBErnLsZ7RkXUAs` — Address derived step by step in the Bitcoin Wiki article on version 1 addresses - `1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2` — Example address of the Bitcoin Wiki article on invoice addresses - `1PMycacnJaSqwwJqjawXBErnLsZ7RkXUAt` (invalid example) — last character changed, the checksum fails - `3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy` (invalid example) — P2SH address (p2shaddr) ## Mappings - autotype: `bitcoin` - presidio: `CRYPTO` - stdnum: `bitcoin` ## Metacrafter rules 2 rules: 1 match the field name, 1 match values. - `p2pkhaddr` (data, `common/cryptocurrency.yaml`) - `p2pkhaddr_by_field` (field, `common/cryptocurrency.yaml`) ## Supported by tools - `autotype` - `dataprep` - `greatexpectations` - `metacrafter` - `openmetadata` - `presidio` - `pythonstdnum` ## Translations - ru: Адрес Bitcoin P2PKH ## Sources - other: - other: ## Quality Score 93/100.
