【Casa Joint Creation: It is not recommended to rely on artificial intelligence to explain the technical details of Bitcoin】 In response to Grok's post stating that "the Bitcoin block size is approximately 664 GB, growing about 72 GB per year, and removing the OP_RETURN limit could increase the block size by about 20%", Casa co-founder Jameson Lopp responded on the X platform, stating: If you rely on artificial intelligence to explain the technical details of Bitcoin, your experience will definitely be terrible; this answer is complete nonsense. The block size data based on OP_RETURN is actually much smaller than that based on witness information records.
