Charles Hoskinson Criticizes Ethereum Researchers for Failing to Study Cardano's Advancements

Charles Hoskinson, the founder of the Cardano blockchain, criticized Ethereum researchers for failing to study the project's advancements over the last seven years.

Charles Hoskinson, founder of the Cardano blockchain, has taken aim at Ethereum researchers for failing to study seven years of advancements made by the project.

The comments follow an interview on the Paul Barron Network, a crypto-focused podcast, where Ethereum researcher Justin Drake discussed Cardano’s security.

According to Drake, risks arise from Cardano’s consensus mechanism, Ouroboros, due to the lack of penalties such as slashing, where validators lose a portion of their staked cryptocurrency for malicious behavior. This, Drake argues, allows attackers to act without facing consequences.

Hoskins has since refuted these claims in a post on X (formerly Twitter), highlighting that Ouroboros provides strong security without relying on slashing. He also emphasized Cardano’s inspiration from Bitcoin’s decentralization principles, which are adapted to its Proof of Stake (PoS) design.

Highlighting the differences between Ouroboros and classical BFT models, Hoskinson explained that classical BFT protocols, which are used to some extent by Ethereum’s PoS, require validators to agree in rounds to finalize blocks and include slashing penalties for misbehavior.

However, Ouroboros does not rely on such rounds and instead provides security through incentives and an innovative staking process. Notably, Cardano’s consensus mechanism can tolerate up to 50% Byzantine resistance, meaning it remains secure even if half of the network participants act maliciously—without the need for slashing or traditional BFT methods.

This capability, according to Hoskinson, sets Cardano apart and is a crucial aspect of its design.

At the time of writing, ETH had gained 6.87% in the past 24 hours, and was trading at $3,920 with a market capitalization of $472 billion. Meanwhile, ADA had surged 13.78% during the same period, reaching $1.15 with a valuation of $40.4 billion.

Cardano’s partnership with Ripple and the Ethereum Foundation’s continued focus on zero-knowledge virtual machines (zkVMs) highlight the competition between the two. Both blockchains are expected to see further price rises as they expand their ecosystems.
