Arbitrum Nova and Nitro

Recently, the Arbitrum team announced that it has opened Arbitrum Nova, which is open only to developers, to all users.

Arbitrum Nova is a new chain developed for very high transaction volume projects that require high security, aiming to further reduce costs for gaming and social applications, and more than 100 projects have already been applied.

It also announced that they will be working together to bring Reddit's community points system to the Ethereum network. The Reddit community points system will be built on the Arbitrum Nova chain and will leverage Arbitrum AnyTrust technology to decentralize the Reddit community.

For further information, check the announcement. You can use Arbitrum nova bridge from here and RPC information can be found here.

Are you ready for Nitro speed Arbitooooors? According to the last announcement, Arbitrum One will migrate to Nitro on 31 August. The team also published the Arbitrum Nitro whitepaper. Let’s dive deeps into Nitro!

Nitro’s design approach consists of four elements:

  • Sequencing, then deterministic execution: First, put transactions into the sequence in which they will be processed, and publish that sequence. Second, apply a deterministic state transition function to each transaction, in sequence.

  • Geth at the core: Nitro uses Geth (Go-Ethereum), which is the most popular Ethereum client, for core execution and state maintenance functions.

  • Separate execution from proving: Nitro compiles the code of its state transition function for two targets: native execution and generates fraud proofs if needed. This dual-target approach assures that execution is fast, while proving is based on structured, machine-independent code.

  • Optimistic Rollup with interactive fraud proofs: Nitro is an improved Optimistic Rollup protocol based on an optimized dissection-based interactive fraud-proof protocol.

You can imagine Arbitrum’s Nitro software designed like a sandwich. The top and bottom layers rely heavily on code from Geth. Yes, it’s a Geth sandwich :)

The base layer and a portion of the middle layer compile codes to WASM for proving. This the where we use deterministic STF (State Transition Function). Because of this determinism, nodes need not communicate and no consensus is necessary among them, in order to agree on the correct state and history. The only thing we have to know is the transaction sequence which is visible to all (Real-time feed + batched data with brotli).

Arbitrum seems to gain momentum with the new Nova solution and Nitro update.

Hepton

Looks like we have a new L2 network. Hepton announced its PoS Sidechain and zkRollup solution.

Hepton PoS will be a separate blockchain that works independently of Ethereum as an EVM-based Ethereum Sidechain and is connected to the Ethereum mainnet by a two-way bridge.

Hepton Standra will be an open-source zkRollup optimized for secure, low-cost, and token transfer on Ethereum. Standra can help centralized institutions involved in the crypto space such as Centralize Exchange in reducing the cost of service.

There is also a testnet for Hepton PoS Sidechain. You can check out the article to experience the testnet. Also, if you want to review the roadmap and tokenomics, you can access them from the links.

Is Optimism Multi-sig Hacked?

on 18 August, $450m worth of OP tokens was transferred out from multi-sig address without any notice.

CT thought that Optimism multi-sig hacked and drained. However, it was routine transfers from multi-sig to VC wallets. OP token price was down nearly %10 after that happened. The Optimism Foundation had to issue a statement to clear up the confusion.

We're seeing some confusion about recent transfers of OP out of a multisig. This is expected—today we executed a series of planned standard transfers to the Coinbase Custody wallets of various investors in OP Labs PBC.

ImmutableX has jumped Solana in daily NFT dollar sales volume, ranking second only to Ethereum. The volume increase has been led by Gods Unchained, DC Comics, and Illuvium Land.

We're psyched to support Nucleo in enabling private multisigs on Ethereum. Currently in beta, Nucleo enables privacy across transactions, DeFi, and fundraising, while providing auditability via shared viewing keys. A huge step toward on-chain privacy for DAOs and organizations.

Progress continues to be made on EIP-4844, summarized in the 3rd and latest community call. It provided an update on the public devnet (with demo!), fee market design, blob sync design, KZG Library support, verification optimization, test coverage, and next steps.

The most underrated feature of validity proofs is they make data availability a strict 1-of-N assumption Invent a permissionless 1-of-N data layer and validiums will be materially as secure as rollups Once that happens, danksharding could be canceled:
polynya.mirror.xyz4844 and DoneAt EthCC yesterday, Vitalik joked “should we cancel sharding?”
