Fractal Bitcoin: We are paying close attention to the "incomplete block filling" situation and will work hard to improve network performance

Fractal Bitcoin officials said on the X platform, "We received some user feedback that the blocks on the Fractal mainnet were incompletely filled. We immediately launched an investigation. Here are more details of what happened: Miners usually prioritize high-fee transactions and are subject to two block size limits: 1) Maximum block size (in bytes); 2) Maximum number of SIG operations. When faced with a large number of high-fee MULTISIG transactions, the block can reach the SIG limit of 80,000 and can no longer contain more transactions. Typically, Segregated Witness (SegWit) transactions consume 1 SIG, and in theory a block can accommodate up to 80,000 transactions (80,000/1=80,000). This is far beyond the standard, so the SIG limit is rarely observed in practice. Transactions containing MULTISIG consume 84 SIGs, which means that if a block is completely filled with such transactions, the maximum number of transactions in a block will be reduced to 80,000/84 = 952. This resulted in incomplete block byte filling. We observed that some random blocks were completely filled because they contained low-fee transactions that were not MULTISIG. These transactions filled the remaining 75% of the block space, causing the total block fee to increase by about 20%. This situation is due to the existing mechanism of the BTC mainnet and is not a defect of the Fractal browser. We will continue to monitor the situation closely and work hard to improve network connectivity and performance. "
