Strip them before validating the address.### 2012-12-14* Renamed the `check_bc` function to `validate` for ease of use.* Added check if the base58-re-encoded address matches the original address Relevant for short addresses with a valid check, but invalid format.bitcoin etf march 30For example: `14oLvT2` The valid version of that address is: `1111111111111111111114oLvT2`* Added alternatives for `long.to_bytes` and `long.from_bytes` for Python versions prior to 3.2* Added unit tests File Type Py Version Uploaded on Size python-bitcoinaddress-0.2.2.tar.gz (md5) Source 2013-08-12 7KB Author: Home Page: /nederhoed/python-bitcoinaddress Keywords: License: Categories Development Status :: 4 - Beta License :: OSI Approved :: GNU General Public License v3 (GPLv3) Programming Language :: Python Package Index Owner: DOAP record: python-bitcoinaddress-0.2.2.xmlbitcoin pledge

TO SEND A BITCOIN TRANSACTION WITH SOME OP_RETURN METADATA ---------------------------------------------------------- On the command line: * python send-OP_RETURN.py is the bitcoin address of the recipient is the amount to send (in units of BTC) is a hex string or raw string containing the OP_RETURN metadata (auto-detection: treated as a hex string if it is a valid one) should be 1 to use the bitcoin testnet, otherwise it can be omitted * Outputs an error if one occurred or the txid if sending was successful * / for your OP_RETURN transaction.* Examples: python send-OP_RETURN.py 149wHUMa41Xm2jnZtqgRx94uGbZD9kPXnS 0.001 'Hello, blockchain!'python send-OP_RETURN.py 149wHUMa41Xm2jnZtqgRx94uGbZD9kPXnS 0.001 48656c6c6f2c20626c6f636b636861696e21 python send-OP_RETURN.py mzEJxCrdva57shpv62udriBBgMECmaPce4 0.001 'Hello, testnet!'

1 As a library: * OP_RETURN_send(send_address, send_amount, metadata, testnet=False) send_address is the bitcoin address of the recipient send_amount is the amount to send (in units of BTC) metadata is a string of raw bytes containing the OP_RETURN metadata testnet is whether to use the bitcoin testnet network (False if omitted) * Returns: {'error': ''} or: {'txid': ''} * Examples OP_RETURN_send('149wHUMa41Xm2jnZtqgRx94uGbZD9kPXnS', 0.001, 'Hello, blockchain!') OP_RETURN_send('mzEJxCrdva57shpv62udriBBgMECmaPce4', 0.001, 'Hello, testnet!', True) TO STORE SOME DATA IN THE BLOCKCHAIN USING OP_RETURNs ----------------------------------------------------- On the command line: * python store-OP_RETURN.py is a hex string or raw string containing the data to be stored (auto-detection: treated as a hex string if it is a valid one) should be 1 to use the bitcoin testnet, otherwise it can be omitted * Outputs an error if one occurred or if successful, the txids that were used to store the data and a short reference that can be used to retrieve it using this library.

* / for your OP_RETURN transactions.* Examples: python store-OP_RETURN.py 'This example stores 47 bytes in the blockchain.'python store-OP_RETURN.py 'This example stores 44 bytes in the testnet.'1 As a library: * OP_RETURN_store(data, testnet=False) data is the string of raw bytes to be stored testnet is whether to use the bitcoin testnet network (False if omitted) * Returns: {'error': ''} or: {'txids': ['<1st txid>', '<2nd txid>', ...], 'ref': ''} * Examples: OP_RETURN_store('This example stores 47 bytes in the blockchain.')OP_RETURN_store('This example stores 44 bytes in the testnet.',True) TO RETRIEVE SOME DATA FROM OP_RETURNs IN THE BLOCKCHAIN ------------------------------------------------------- On the command line: * python retrieve-OP_RETURN.py is the reference that was returned by a previous storage operation should be 1 to use the bitcoin testnet, otherwise it can be omitted * Outputs an error if one occurred or if successful, the retrieved data in hexadecimal and ASCII format, a list of the txids used to store the data, a list of the blocks in which the data is stored, and (if available) the best ref for retrieving the data quickly in future.

This may or may not be different from the ref you provided.* Examples: python retrieve-OP_RETURN.py 356115-052075 python retrieve-OP_RETURN.py 396381-059737 1 As a library: * OP_RETURN_retrieve(ref, max_results=1, testnet=False) ref is the reference that was returned by a previous storage operation max_results is the maximum number of results to retrieve (in general, omit for 1) testnet is whether to use the bitcoin testnet network (False if omitted) * Returns: {'error': ''} or: {'data': '', 'txids': ['<1st txid>', '<2nd txid>', ...], 'heights': [, , ...], 'ref': '', 'error': ''} A value of 0 in the 'heights' array means some data is still in the mempool.The 'ref' and 'error' elements are only present if appropriate.* Examples: OP_RETURN_retrieve('356115-052075') OP_RETURN_retrieve('396381-059737', 1, True) VERSION HISTORY --------------- v2.0.2 - 30 June 2015 * First port of php-OP_RETURN to Python
