Ethereum Developer Lefteris Karapetsas Opposes Validator Rewards Funding Proposal Renowned Ethereum developer and Rotki founder Lefteris Karapetsas has publicly opposed the recently debated proposal to 'fund core development using validator rewards.' He highlighted two key issues: first, this mechanism could create a cartel of large stakers, potentially redirecting up to 10% of network-wide validator rewards and deciding the allocation of funds themselves; second, he is unwilling to perpetuate a core development culture that has been out of touch with actual developer needs for the past 10 years. He also stated that if a funding mechanism is truly necessary, he would prefer using burned ETH transaction fees instead of taking a cut from validator rewards.
