There has been an ongoing Bitcoin block size debate, and most recently a radical, old idea resurfaced: instead of increasing the block size from 1MB to 2,4 or 8MB, the protocol should be changed to accommodate 32MB blocks. This probably pissed off Bram Cohen.
Are 32MB Blocks Too Big?
Here’s why that’s not a radical idea: it’s how Satoshi Nakamoto, creator of Bitcoin, for a time had designed Bitcoin before settling on a 1MB transaction size — a decision which, perhaps, led to Bitcoin being christened “digital gold.”
Calls for large block sizes are not so uncommon: Gavin Andresen himself once did exactly this.
