EIP-8363 Criticized: Issuance Cut Lacks Model Support, Called 'Shelling Point Meme'

banteg · x · 2026-08-15

Ethereum developer banteg criticizes EIP-8363, arguing it works backwards from a chosen policy endpoint (canceling issuance when staked ETH reaches 50%), which is not derived from security optimum, staking supply curve, or validator composition model, but defended as the 'last natural stopping place'—essentially a shelling point meme. The proposal claims favorable effects on validator composition and behavior without modeling cohort responses. banteg contrasts with more rigorous 2024 issuance debate, noting EIP-8363 invokes Elowsson's work while treating as settled several effects his FAQ classified as unresolved. He emphasizes we don't know the staking supply curve, so optimal staking ratio cannot be derived from first principles. Elowsson modeled multiple supply curves and considered MEV, variance, economies of scale, solo staker costs, but concluded whether lower issuance worsens solo staker share is unknown. EIP-8363 extrapolates mathematical properties into claims about real-world behavior (self-limiting large operators, resistance to capture, decentralization protection) without credible models. banteg concludes unresolved questions from 2024 haven't disappeared; discussion quality has cratered, uncertainties promoted to assumptions.
