Today, we are excited to open source Reth Alphanet.

Reth AlphaNet is an OP Stack-compatible testnet rollup that maximizes Reth performance and enables experimentation of bleeding edge Ethereum Research. You can find the full announcement below.

Introducing Frog 🐸 – A *Frame*work for Farcaster.

Frog is an open-source framework for @Farcaster_xyz developers to build high quality, performant, & lightweight Frames in just a few blocks of code.

Built as part of the @wevm_dev x @paradigm collab. Read on! .@Farcaster_xyz’s programmable feed, enabled by Frames, is one of the most exciting things happening in web3. We felt like this deserved a world-class devtool experience.

You can find our post below:

6 useful projects I’d (selfishly) love to see built during #ETHDenver 🧵 OP-Reth

The OP Stack implements an Optimistic Rollup design that aims to be as close to Ethereum. See @protolambda's diff here: op-geth.optimism.io

Would love to see an implementation in Reth: github.com/paradigmxyz/re…

@refcells is already working on this, reach out

Excited to be open-sourcing Reth, an Ethereum execution layer in @rustlang 🦀

Reth is a new Apache/MIT-licensed full-node implementation of Ethereum by @paradigm and the community, focused on contributor-friendliness, modularity, and performance.

paradigm.xyz/2022/12/reth We are building Reth for 3 reasons:

1. Building a performant node for power users
2. Contributing to Ethereum’s stability by improving client diversity
3. Giving back to Ethereum by contributing to the roadmap

.@paradigm is building Reth, a Rust Ethereum Execution Layer.

Reth is not a fork or a rewrite of any other client implementation.

It is a new Apache/MIT-licensed full node implementation of Ethereum focused on contributor friendliness, modularity, and performance. 1/8 Reth does not include code from any existing client but stands on the shoulders of giants including Geth, Erigon and Akula.

We sponsored the project in the interest of client diversity, so we are sorry to see any other project ceasing development. It is a loss for the space. 2/8

NEW @paradigm Research (& Engineering)!

This time, @a_kirillo and @jneu_net and I teamed up to see if we can bring Narwhal & Bullshark, a novel mempool & consensus algorithm, to the Cosmos ecosystem 🧵 1/18

paradigm.xyz/2022/07/experi… As more and more blockchain systems get deployed to production, two problems are frequently encountered:

1. Achieving consensus with high throughput and low latency paradigm.xyz/2022/07/consen… (cc @LefKok)
2. Building a distributed application on top of that consensus

🔥⚒️ NEW FOUNDRY RELEASE 🔥⚒️

Announcing Solidity Scripting & Deployments!

This is a game changing feature we've been designing since January, with @brockjelmore starting it and @joshie_sh getting it over the line last week.

Read on to learn more.

github.com/foundry-rs/fou…

1/N @brockjelmore @joshie_sh Scripting & Deployments are critical for making Foundry more than just a testing framework, and expanding on ChainOps.

Following our Solidity-centric philosophy, we introduce a new set of cheatcodes (`broadcast`), which make any calls affected by them to be posted onchain.

tl;dr:
1. proposer boost (was created to counteract balancing attacks (arxiv.org/abs/2203.01315, eprint.iacr.org/2021/1413.pdf) on Ethereum PoS
2. only some nodes had upgraded
3. reorg caused due to boost applied by some but not all nodes
4. not an issue as all nodes eventually upgrade

🔥⚒️ NEW FOUNDRY RELEASE 🔥⚒️

Announcing Anvil, a blazing-fast local testnet node implementation, in Rust!

You can consider Anvil a drop-in replacement for `ganache-cli` or `hardhat node`, for deploying & testing your contracts from frontends or interacting over RPC. 1/N In the spirit of all Foundry tools, Anvil is fast! ~3.5x faster than Hardhat on @uniswap/v3-periphery.

This is still an early release, so more testing is welcome here, so that we can further improve performance and/or identify edge cases!

Domino effect of now uncollateralized loans against wormhole ETH severely undermentioned Worth noting that criticisms against @wormholecrypto security model are quite irrelevant here. This is a smart contract bug, can happen to anything, whether it is a multisig or a rollup bridge. We need better critics as usual :)

IMO problem is that there's too many junior tutorials (any dev can learn basic Solidity syntax in a weekend) vs more advanced ones for senior ppl, some examples being gas optimizations, patterns for vault/staking/governance/asset transfer contracts, fuzzing/testing workflows etc.

Fullstack intro to Solidity + React tutorials = missing the point

Solidity guides CANNOT include "btw here's how you learn to write mocha tests in javascript"

Excited to announce Foundry!

Foundry is a portable, fast and modular toolkit for Ethereum application development 🧵

paradigm.xyz/2021/12/introd… Foundry is a reimplementation of the testing framework @dapptools, written in Rust to be blazing fast, easy to install, and friendly to a wider set of contributors.

While our codebase is not a fork, a huge THANK YOU to the DappHub team for creating and maintaining DappTools.

I’m excited to announce LootLoose.com.

LootLoose lets you unbundle your @lootproject bags into individual ERC1155 NFTs or rebundle them into their original Loot bags.

@_anishagnihotri built the frontend, and I did the smart contracts.

⬇️Thread 1/10. Each @lootproject bag is an ERC721 NFT containing 8 individual items.

However, we’ve seen user demand gravitate towards select items like Divine Robes or Katanas.

With LootLoose, you can open a bag and unbundle its items into individual ERC1155 NFTs. 2/10

Sober thread on EIP-1559 by Taylor, agree & disagree with many of the points brought up. Thoughts below..

https://twitter.com/tayvano_/status/1397725861575421953

It indeed smooths out gasprice vol, not 'make fees low'

Periods of rapidly increasing demand are controlled via the BASEFEE's exp. increase

Miner incentives remain the same, the EIP does not introduce any new attacks! That's a good thing!

The Berlin Ethereum network upgrade (aka hard fork) is scheduled to happen on mainnet in block 12,244,000, ~41 days from now (etherscan.io/block/countdow…)

EIP-2929: Gas cost increases for state access opcodes (eips.ethereum.org/EIPS/eip-2929)

State access opcodes have historically been underpriced as found by @danhper in arxiv.org/pdf/1909.07220….

This EIP increases the gas cost for the first time a slot or account is accessed. 2/14

Here's an example of how traders can use Flashbots' APIs to submit 0-gasPrice transactions directly to MEV-GETH-enabled miners.

Each bundle must include a tx that pays the miner either directly or via a contract call to `block.coinbase.transfer(amount)`

SIDECHAINS ARE NOT LAYER 2

Let's put a myth to bed.

Thread on the history of sidechains, their security properites, concluded by their differences to Layer 2 solutions.

(there’s a lot of resources, feel free to skip/bookmark for later!)
