According to Odaily, Casa co-founder Jameson Lopp has responded to claims made by Grok regarding Bitcoin's block size. Grok stated that Bitcoin's block size is approximately 664 GB, with an annual growth of about 72 GB, and suggested that removing OP_RETURN restrictions could increase block size by around 20%. Lopp, addressing these assertions on the X platform, criticized the reliance on artificial intelligence for explaining Bitcoin's technical details, calling the answer misleading. He clarified that block size data based on OP_RETURN is significantly smaller than that based on witness information records.
