Researcher Hopes Cosmos-Style ‘Checkpoint’ Could Fix Ethereum’s Data Problem – CoinDesk – CoinDesk

Ethereum developers are aspiring to launch Eth 2.0 in 2020. But that doesn’t mean all the technical details have been spelled out yet.

The sum of account balances maintained by the network’s nodes – called the state – continues to grow larger and larger as applications and projects transact. Adoption is good, but runaway growth is bad. Independent developer Alexey Akhunov may have a solution – one pulled from Cosmos, the interoperability blockchain.

His new proposal, dubbed “ReGenesis,” posted on EthResearch on June 24, would bring stateless client research to the current Ethereum chain (also known as Eth 1.x) by “nuking” certain nodes’ states and swapping them with a math proof on a rolling basis.

The purpose? Make Ethereum’s data set scalable with minimal sacrifices to security. 

“Some of the older nodes will forget about the state,” Akhunov said in an interview with CoinDesk. “At this point in time, all the nodes will forget what the state was. They will only remember the hash.”


Nuking the blockchain isn’t a novel idea. In fact, the idea is mentioned in the Ethereum yellow paper by co-founder Gavin Wood.

Akhunov said he drew inspiration for his interpretation of ReGenesis from Cosmos, which has undergone a similar procedure Source…
