code. Import pyhash # from m/flier/pyfasthash murmur3 rmur3_32 def bloom_hash(nHashNum, data seed (nHashNum * 0xfba4c795 nTweak) 0xffffffff return( murmur3(data, seedseed) (nFilterBytes * 8) ) We setup our hash function template using the formula and 0xfba4c795 constant set in BIP37. PaymentRequest PaymentDetails Edit History Report Issue Discuss The PaymentRequest is created with data structures built using Googles Protocol Buffers. Filter bytes: 2 "b50f" #. These examples are to help you learn, not for you to emulate on mainnet. We save the resulting raw format transaction to a shell variable.

(To maintain the same false-positive rate, you would need a larger filter size as computed earlier.) Note: for a more optimized Python implementation with fewer external dependencies, see python-bitcoinlibs bloom filter module which is based directly on Bitcoin Cores C implementation. Each code block precedes the paragraph describing. Community Bounties Seeder Node Campaign decentralized through more unique volunteers, trezor Hardware Wallet Integration, ledger Hardware Wallet Integration.
