In a tweet today, Charles Hoskinson, the founder of Input Output Global (IOG), the team behind the Cardano network, slammed Ethereum founder Vitalik Buterin’s assertion that the network should tolerate solo validator censorship.
Buterin’s logic, according to Hoskinson, follows the logic behind the “DAO hack,” adding that the Ethereum founder is crossing lines in the name of crypto adoption and progress.
While it is unclear which DAO hack Hoskinson is referring to, it is worth noting that Mango DAO lost over $113 million in an exploit last Tuesday. As a result of the DAO’s insolvency, it negotiated a $47 million bounty with its attacks to receive $66 million from the loot.
Notably, Avraham Eisenberg claimed to be a member of the group responsible for the exploit on Saturday that their actions were legal and justifiable as a risk-free trading strategy.
Hoskinson’s latest comments came after an ADA stake pool operator (SPO) drew attention to Buterin’s comments and stated that if Hoskinson made the same comments, crypto media would be less favorable. According to the SPO, Ethereum appeared to be devoid of guiding principles, making things up as they went along.
It is worth noting that since Ethereum switched to proof-of-stake (PoS) in September, concerns about centralization have reached a fever pitch. Morgan Stanley, the most recent commentator, noted that 65% of Ethereum’s nodes are cloud-hosted, with Amazon Web Services hosting half of these. Furthermore, only four companies own 60% of the network’s validators.
Among all of this, Ethereum’s Vitalik Buterin has stated that it is acceptable for solo validators to select the transactions they want to include in their block within a certain margin.
As previously stated, this is unlikely to cause any harm because the network will still include these weakly censored transactions in the chain as long as one validator approves it. However, it is different if these validators decide not to attest to blocks containing transactions that do not correspond to their personal beliefs.
Notably, this debate is not limited to Ethereum; experts have debated whether it is ethical for non-mining Bitcoin nodes to refuse to validate certain transactions and whether these nodes ultimately matter.
It is worth noting that censorship is widely regarded as incompatible with crypto ethics and the Bitcoin vision.
It is worth noting that no love is lost between the Cardano and Ethereum communities, and Hoskinson continues to criticize Ethereum PoS at every opportunity.
