MetaMask Developer ConsenSys Brings Layer 2 Blockchain ‘Linea’ To Ethereum Mainnet


  • ConsenSys is ready to deploy Linea, its ZK-rollup community, to the principle Ethereum community.

  • Linea makes use of zero-knowledge (ZK) cryptography to supply cheaper and sooner blockchain transactions; ConsenSys says charge charges, referred to as gasoline costs, can be 15 instances much less on Linea than Ethereum.

  • ConsenSys says it doesn’t presently have plans for a Linea token.

ConsenSys, the analysis and improvement agency behind the favored Metamask crypto pockets, plans to roll out its layer-2 community, Linea, to the principle Ethereum community this week.

The so-called rollup community is called a zkEVM, which implies it depends on zero-knowledge (ZK) cryptography – one in every of this yr’s hottest blockchain developments – and is suitable with the Ethereum Digital Machine (EVM) programming surroundings, so present Ethereum-based purposes will be ported over with out vital extra work. Rollups are seen as a crucial factor of the Ethereum blockchain’s roadmap, since they provide customers cheaper and sooner transactions in contrast with the often-congested guardian community.

App builders will have the ability to deploy their tasks to Linea’s “alpha” community on Friday, with most people having access to it beginning subsequent week.

With the mainnet alpha launch, Linea joins a string of current zkEVM tasks vying to develop accessibility to Ethereum, the second-biggest blockchain by transaction quantity. Rollup networks like Linea are anticipated to ultimately turn out to be the first methodology by which customers entry Ethereum, thought-about impractical for a lot of customers and use circumstances resulting from its excessive charges.

“As a result of the gasoline costs on the layer 2 are 15 instances lower than on layer 1, many use circumstances turn out to be potential,” Nicolas Liochon, the worldwide product lead for Linea, instructed CoinDesk.

ConsenSys is led by Ethereum co-founder Joe Lubin and builds among the ecosystem’s core infrastructure, together with MetaMask in addition to Infura.

Emphasizing that ConsenSys stays “devoted to Ethereum,” Liochon stated that “by shifting over actions to layer 2, we principally are capable of enhance, by a number of orders of magnitude, the variety of folks that may have the ability to use the community.”

The primary Ethereum rollups to market, Optimism and Arbitrum, have been so-called “optimistic” rollups – based mostly on a barely completely different expertise that comes with the downside of prolonged settlement instances.

Newer ZK rollups like Linea work equally – bundling up massive teams of transactions and “settling” them in bulk to Ethereum’s ledger – however their builders are betting ZK cryptography will ultimately make them speedier, cheaper, and safer than optimistic options.

In contrast to a few of its zkEVM opponents, ConsenSys opted to make its community bytecode-compatible with the EVM – a technical nuance that would theoretically make Linea simpler to make use of with present Ethereum developer instruments.

Many present layer 2 networks, like Arbitrum and Optimism, have “airdropped” tokens to early customers after launching to the principle Ethereum community. The tokens could possibly be offered for a fast revenue or used as votes to assist govern updates to the protocol; dangling the prospect of an airdrop is seen as a approach of encouraging customers to check out new networks.

There has lengthy been hypothesis that ConsenSys would possibly ultimately launch a token for Linea. Whereas Liochon wouldn’t depend out the potential of a Linea token, he stated that if it ever does arrive, it gained’t be for some time.

“What can we wish to do? Will we wish to get wealthy shortly, or can we wish to construct one thing?” requested Liochion. “Yeah, principally, I believe that we should always construct issues.”

Ethereum’s rollup panorama

Linea’s launch comes after zkSync and Polygon, the primary two zkEVM networks to launch on Ethereum’s mainnet, launched software program improvement kits (SDKs) permitting coders to clone their code to spin up their very own rollup networks.

ConsenSys says Linea will turn out to be totally open-source within the coming weeks, that means builders will have the ability to freely use its code (although ConsenSys has no present plans to launch an SDK).

Zero-knowledge rollup expertise is new and nonetheless advancing. As Linea enters its alpha launch, it should nonetheless have sure factors of centralization in its system – which Liochon refers to as “coaching wheels” – as a strategy to shield customers from unexpected bugs and different hiccups.

For now, ConsenSys will nonetheless be the one celebration allowed to submit zero-knowledge proofs to Linea’s good contracts on Ethereum. In layman’s phrases, this implies the agency will act as a form of transaction visitors cop in the interim – directing transactions and packaging them up into the bundles that it sends to Ethereum.

“For those who’re totally decentralized, principally the concept is that anybody can submit proofs,” stated Liochon. “However it’s essential to be 100% positive that there’s no difficulty in your proof system. We’re not there but.”
