Offchain Labs acquires Ethereum core dev team Prysmatic Labs

Published at: Oct. 13, 2022

One of the core development teams behind the Ethereum (ETH) Merge, Prysmatic Labs, has been acquired by Offchain Labs, the developer of Ethereum layer-2 network Arbitrum. 

Announced in an Oct. 13 blog post by Offchain Labs, the deal's financial terms were not disclosed, but it was noted Prysmatic Labs chose to join Offchain Labs "for many reasons," but mainly because of the two companies' alignment in their core beliefs.

Prysmatic Labs co-founder Raul Jordan said the move will "build a unified team stronger than the sum of its parts."

"Merging with Offchain Labs made perfect sense to us as an Ethereum team because we develop software extensively in Go, are fully incentive-aligned with the success of Ethereum, and are focused on shipping quality software for others to use,” Jordan said.

Offchain Labs claims the future of ETH relies on layer 1 for consensus and data availability and layer 2 for execution and scalability, and its acquisition of Prysmatic Labs is a step toward combining experts in these two areas.

Despite the Prysmatic Labs team officially joining Offchain Labs, their "work will continue uninterrupted," and their work in Ethereum node client software will continue to be developed under Offchain's umbrella.

They are still developing Prysm as a fully open-source and neutral consensus client and bringing EIP-4844 data-sharding to production.

The post ends by teasing possible future collaborations between the two teams.

“There are several other joint initiatives that we plan to work on together, furthering both L1 and L2 development.”

Prysmatic Labs is one of the core engineering teams behind the Merge and built Prysm, the leading ETH consensus client that's now powering Ethereum's proof-of-stake consensus.

Offchain Labs is a venture-backed and Princeton-founded company developing Arbitrum, a suite of scaling technologies for Ethereum, with two live chains, Arbitrum One and Arbitrum Nova.

Layer-two scaling solutions solve enterprises’ public blockchain challenges
At the end of 2019, research firm Forrester and Big Four firm Ernst & Young, or EY, published a report surveying the adoption of public blockchains by enterprises. Findings revealed that 75% of respondents were likely to use a public blockchain in the future. Although this was the case, the report also found that most enterprises were still using private blockchains to ensure security, privacy and scalability. What was also noted in the survey as the top three concerns regarding public blockchain networks were a lack of maturity, security and privacy issues. Fast forward to 2021 — these concerns remain. …

Bitmain’s new Ether ASIC mining rig may not fix GPU shortage after all
Cryptocurrency mining rig manufacturer Bitmain announced the pending release of a new Ether (ETH) miner on Friday. The Antminer E9 model is an application-specific integrated circuit chip that will run on the Ethereum blockchain’s Ethash algorithm. No official release date has been announced for the E9 yet, however, the machine’s arrival may not be as impactful as first suspected. The rig faces competition in the form of Nvidia’s CMP (Cryptocurrency Mining Processor) range of GPUs designed specifically for crypto mining. Meanwhile, Ethereum’s scheduled move away from proof-of-work to a proof-of-stake consensus mechanism could mean the E9’s utility will be short-lived. …

Why Interoperability Is the Key to Future Innovation and Adoption
For years, tribalism has plagued the blockchain industry. Developers align to specific consensus protocols and defend technologies that use them, regardless of their limitations. These deeply rooted divisions are slowing the innovation needed to scale blockchain for future adoption. The enterprise market is only beginning to understand the promise of blockchain, and that promise will be difficult to achieve until blockchains can communicate and cooperate with each other. To achieve this, developers, companies and hobbyists alike must be able to leverage every platform without being locked into one simply because the platform developers are not working together. Blockchain can bring …

Ethereum advances with standards for smart contract security audits
The Ethereum ecosystem continues to witness a flurry of activity that has individuals and organizations deploying token contracts, adding liquidity to pools and deploying smart contracts to support a wide range of business models. While notable, this growth has also been riddled with security exploits, leaving decentralized finance (DeFi) protocols vulnerable to hacks and scams. For instance, recent findings from crypto intelligence firm Chainalysis show that crypto-related hacks have increased by 58.3% from the beginning of the year through July 2022. The report further notes that $1.9 billion has been lost to hacks during this timeframe — a figure that …
