On April 24, chain data showed that in the past 12 hours, the average handling fee on the Bitcoin main network has risen sharply from about 2 ats/vByte to 25 ats/vByte, and the short-term peak once hit 120 ats/vByte. On-chain monitoring found that a large number of P2SH UTXO Bundling transactions were launched in a concentrated manner, which was caused by the Bitcoin Thunderbolt "Boostpad" time-limited airdrop event and the Alkanes inscription launch last night. The bidding for miners 'fees increased significantly. Previously, on April 15, HSBC's official press release disclosed for the first time that Bitcoin Thunderbolt introduced UTXO Bundling and OP_CAT instructions through the main network soft fork, supporting native asset issuance, transaction acceleration and intelligent verification on the chain. The measured network efficiency is 100 - 200 times higher than that of the original chain.
