Vitalik: We have underestimated how long it will take to implement Proof-of-Stake and Sharding


The Hashing It Out podcast recently hosted Ethereum co-founder Vitalik Buterin. During the program, he explained how he would handle the creation of the Ethereum in a different way today.

Buterin acknowledged the presence of a number of changes, both large and small, such as thinking more about gas costs. „We didn’t really do a good job of establishing them in the first place,“ Buterin said in the July 2 podcast interview.

Buterin’s biggest changes involve sharding and Proof-of-Stake

After mentioning gas prices and other minor modifications he would have made from the beginning, Buterin took a look at some of the most important changes around Ethereum.

„We definitely underestimated the amount of time it would take to finish a lot of the things we didn’t start in 2015,“ Buterin said, pointing to the Proof-of-Stake, or PoS, and sharding as the most significant aspects.

He added:

„If we had known it would take years, we probably would have designed the roadmap differently, thought about what different teams would be working on in a different way, making a lot of decisions about it in a very different way than we are now, so I think there are definitely a lot of regrets and wasted time on those aspects.
