this is certainly my lack of understanding, but it challenge what i know about blockchain.
I created a new address p2wpkh from public key with bech32 (testnet) on 2022-11-10 : tb1q9ctu2t7zqvlevcamga9dfdhvlpeh93qdz6aawk Made one transaction on 2022-11-10 10:29
b_pubkey = bytes.fromhex(pubkey) h160 = hash_160(b_pubkey) segwit_hrp = 'tb' encoding = Encoding.BECH32 address = bech32_encode(encoding, segwit_hrp,  + convertbits(h160, 8, 5))
But in mempool it shows it has 3 transactions, goes back to 2022-11-07 15:10 https://mempool.space/testnet/address/tb1q9ctu2t7zqvlevcamga9dfdhvlpeh93qdz6aawk
aren't addresses supposed to be unique and collision resistant ?
