Eth News and Links

Mainnet execution layer

• December upgrade proposed as difficulty bomb delay only, named Arrow Glacier

• Erigon v2021.09.04: reimplements transaction pool as separable (separate process/computer and multiple processes for one node)

• Nethermind v1.11.3: performance optimization in JSON-RPC and transactions broadcasting

EIPs/Standards

• EIP3978: Gas refunds on reverts

• EIP4200: Static relative jumps

Proof of stake consensus layer

• If beacon chain consensus fails, stakers run the risk of incurring large penalties (~%75 of their balance) if they use a majority client/cloud provider/staking service and won’t be bailed out!

• Client diversity estimate from block proposal data using block attestation fingerprinting, Prysm is ~65%

• Altair upgrade of the beacon chain set for epoch 74240, October 27

• Latest What’s New in Eth2

• PoS implementers call. Notes from Ben Edgington: sync committee issues resolved

• Proto’s visualization of debugging performance of 200k+ validators on Prater testnet

• Wagyu: GUI to create and restore validator keys (offline), testnet only

• Feist-Khovratovich technique for computing KZG proofs fast

Layer2

• An exhaustive list of projects on Arbitrum (caveat emptor, as always)

• Avoid long optimistic rollup withdrawal delays: use Celer cBridge 2.0 with improved user experience and LPs have option not to run a cBridge node

• Aztec increases caps to 30 ETH, 100k DAI and 2 renBTC for private transactions on its zk rollup

• Bitfinex directly supports bridge to DeversiFi (StarkWare-based layer2), starting with USDT

• Solidity to Cairo transpiler switched from transpiling EVM opcodes to using a combination of Solidity & Yul AST

• Censorship resistance: Arbitrum and Optimism users can force transactions to layer1 whilst StarkWare layer2s use app specific mechanisms

• Geohot returns: cannon, on chain interactive fraud prover

This newsletter is made possible thanks to GridPlus’s Lattice hardware wallet!

What good is a hardware wallet if you can’t be sure of what you’re signing?  

The Lattice is the first and only hardware wallet that securely shows you a human readable version of an Ethereum transaction.  Anything else is just security theater.

Just as importantly, the Lattice is the only hardware wallet that is built to be resistant to physical tampering.  

We can’t leak your data if we don’t have it: we never store your name or address even a single day longer than we have to. 

Isn’t your crypto worth securing?  Buy a Lattice today.

Stuff for developers

• Ganache v7.0.0 alpha.1: local blockchain (formerly ganache-cli), London EIP1559 support

• Discussion on whether Solidity libraries should behave like contracts

• Hardhat Ignition: deployment system for structuring, automating, and distributing contract deployment setups, in development for 2022

• eth-hooks (TypeScript): commonly used hooks such as balances, provider, contract loader and ENS resolver, from scaffold-eth

• gas-estimation: MyCrypto EIP1559 library, uses last 10 blocks from an Ethereum node

• Moloch v3 proposal (codenamed Baal): adds Compound-style delegation, DAO controlled share and loot transferability

• nile (for Cairo): compile and manage artifacts for StarkNet projects, install Cairo language

• Guide to create ERC20 payment splitter using OpenZeppelin & Hardhat

Ecosystem

• MEV impact on gas prices, increases for priority gas and during high volatility non-priority gas but reduces the waste from pre-Flashbots

• Proposed Sign-in With Ethereum workflows
