During Paris Blockchain Week Summit, Coin Rivet had the exclusive chance to sit down with Cornell University Professor, Emin Gün Sirer, about many topics around network consensus for protocol changes on Ethereum and Bitcoin.

Speaking on the topic of the much publicised UASF movement that lead to eventual soft fork implementation of the Segwit protocol for Bitcoin, the academic stated that “in some sense, I am, the grandfather of the UASF movement”.

He went on to say how Bitcoin maximalists would find it hard to admit that consensus was not initially with them as they pushed for the Segwit scaling upgrade, instead of changing the block size limit to increase transaction capability on the layer one Bitcoin blockchain.

Hash power was not enough

Emin said that back when Core was pushing their narrative, and back before they had Jihan Wu on their side, “I was the lone person saying it is not enough to just have hash power with you”.

At the time of the scaling debate, we could see that Jihan and other major Bitcoin miners (prior to the split of Bitcoin Cash) were not prepared to signal their support towards Core’s scaling roadmap if it did not directly benefit the miners in terms of network fees paid to process more transactions on the Bitcoin blockchain.

The academic said that, in his opinion, “hash power does not determine the contents of the chain, the users determine the contents of the chain. My writings on this stuff go back to 2014, so about half a decade ago I was making the case for UASF”.

Flipping the narrative

Gun Sirer then told us how “Luke-dash Junior and friends came up after me” and “once Core lost miner support, they flipped their narrative entirely”.

He went on to tell us how you “don’t really see principled people flipping and flopping like that. It makes you kind of lose respect, I was steady with the same principles and set of scientifically backed things”.

He also made the case that instead of just the core developers or miners on the Bitcoin network, “the rules that are enforced are determined by the users, and the rules that are adopted are determined by the economic majority. That has never changed”.

Specifically on UASF, he said that it “played a role in determining the date of the fork, but deep down what was happening was a fundamental split in the community”.

Stay tuned for part two of this exclusive interview where Gun Sirer shares his views on the Segwit 2x fiasco and Ethereum’s move to a Proof-of-Stake network.
