That’s the finding from Selfish Behavior in the Tezos Proof-of-Stake Protocol, published last November by then-Harvard researcher and current Google engineering intern Michael Neuder. The paper from Neuder and other Harvard researchers shows the profitability – albeit small – of “selfish endorsing” attacks in Tezos, a variant of selfish mining. Luckily for Tezos, the selfish mining concern can easily be patched through the network’s flexible on-chain…
