TechFlow reports that Taiko, an Ethereum Layer 2 network based on zkRollup technology, has announced the launch of Eldfell L3 (Alpha-4 testnet). This testnet aims to test deploying Taiko as an initial layer for L3s (rollups on a rollup) on top of Taiko itself, as well as testing a new staking-based prover economics model.
In the Alpha-3 version, Taiko's design rewarded only the first successful prover. However, in testnet scenarios, this led to many provers "wasting work" as they all competed to prove the same block, with only one ultimately receiving the reward.
In Alpha-4, the protocol selects a prover from a pool and assigns it to a proposed block. The designated prover must then submit a valid proof within a defined time window to complete block validation. If the prover fails to submit the proof on time, their stake will be slashed. The higher the amount of staked tokens, the greater the chance a prover has of being selected.
