The debate whether or not to increase bitcoin’s block size exposes how difficult it is to make changes to p2p protocols like bitcoin. Personally, I think the block size needs to be increased as recommended and pushed by Gavin Andreson. So it boggles my mind on how difficult it is to reach consensus on what seems like a no-brainer decision.
Regardless of my stance on the matter, it shows how reaching consensus becomes harder and harder as a p2p protocol like bitcoin becomes bigger and bigger and more established. Safecoin will avoid this problem because there is no blockchain and uses a very different protocol/solution.
But when safecoin and the SAFE network gets bigger and bigger, there will be no doubt changes will need to made to the protocol as it matures. So how will future changes be implemented if a consensus cannot be met? Will it only take accidents and bugs to force a change to the SAFE protocol? Will SAFE forks be required so competition will decide which version to use?
