Adam Back, CEO of Blockstream, pushed back on renewed claims that Satoshi Nakamoto clearly supported larger Bitcoin blocks, arguing that the Bitcoin creator's comments on scaling were contradictory, context-dependent and sometimes simply wrong. The debate resurfaced after criticism of a developer interview on X prompted big-block advocates to recirculate old Satoshi posts, including a BitcoinTalk line saying block-size changes could be phased in later and a 2009 remark suggesting Moore's Law would outpace chain growth. Back argued those quotes do not settle the issue, pointing instead to Satoshi's 2008 exchange with James A. Donald, where Nakamoto said a growing network would increasingly rely on specialists with server farms and lightweight clients. Back said that record cuts both ways and that Satoshi's expectation that hardware gains would comfortably absorb blockchain growth did not hold up, with the chain now around 744 gigabytes. He framed the later remarks as closer to an early case for second layers that move activity off-chain, and said developers should reason from first principles rather than treat decade-old forum posts as binding authority. Bitcoin was trading near $64,168, about 49% below its October 2025 record of $126,080.
