Eth News and Links

Eth1

  • Leading game theorist Tim Roughgarden publishes his positive analysis of 1559

  • Latest eip1559 implementation call. Beiko’s notes, with a path to mainnet

  • A code merkleization explainer

Proof of Stake launches successfully

  • The Beacon chain launched, with the first block graffiti reading “Mr F was here” (beaconscan, beaconchain) and the network participation rate quickly reaching an astonishing 98-99% (beaconchain, beaconscan)

  • Meanwhile the deposit contract is over 1m ETH, so now more than 1% of all ETH is locked for staking. That number is only going to go up, right now that puts annual staking rewards at 14.6%. That means the network is continually increasing its decentralization

  • There have been 3 slashing events, all by stakers (and a pool known as Ankr) running their keys on multiple machines. This was already a known bad idea! Slashing is bad, going offline is very insignificant in comparison

  • Before genesis, Prysmatic published slashing prevention tips. It emphasized that you should never run your key in multiple places.

  • Pre-launch what’s new in eth2

  • Superphiz: hold off on staking with trusted pools/exchanges

Proof of Stake plans

  • Latest eth2 call. Notes from Ben and Mamy

  • Shift computing costs from end of epoch to mid-epoch

Layer2

  • Loopring’s AMM is live on their zkrollup (though limited to LRC/ETH for now)

  • Golem’s latest release uses Zksync zkrollup for transfers

  • Deversifi’s validium (off-chain data held by committee) upgrades to StarkEx v2 which includes fast withdrawals and a Turing-complete STARK proof language, though non-conformant ERC20 tokens (OMG, USDT) won’t work for another month
