Orphaned blocks are very rare in Bitcoin.

Even if you somehow saved all this wasted hash power, you would only maybe increase hash power by less than 1%!!!

- DennisP 7y agoSounds like we vehemently agree. Orphaned blocks are indeed rare in Bitcoin, because they have ten-minute block times. GHOST only helps when block times are so short that you get lots of orphaned blocks. And that's how Ethereum gets away with 15-second blocks.
- codexon 7y agoBut you haven't proven that 1 ETH 15 second block is equal or even in the same ballpark in security to a 10 minute BTC block.
