April 24 news, chain data shows that in the past 12 hours, the average transaction fee on the Bitcoin mainnet has surged from about 2 sats/vByte to 25 sats/vByte, with a short-term peak once reaching 120 sats/vByte. On-chain monitoring has found that a large number of P2SH UTXO Bundling transactions are being initiated, attributed to the Bitcoin Thunderbolt “Boostpad” limited-time airdrop event and Alkanes inscription release that went live last night, causing a significant increase in miner fee bidding. Previously, on April 15, HSBC's official press release first disclosed that Bitcoin Thunderbolt introduced UTXO Bundling and OP_CAT instructions through a mainnet soft fork, supporting on-chain native asset issuance, transaction acceleration, and smart verification. The network's tested efficiency is improved by 100–200 times compared to the original chain.
