Author: Valentin Wustholz Many Layer 2 (L2) blockchains, including Linea, rely on zero-knowledge (ZK) infrastructure. This infrastructure is highly complex ("moon math") and critical for the correct operation of these chains. In other words, even a single bug can result in catastrophic financial and reputational damage. Even though we have not seen a catastrophic incident in ZK-based L2s comparable to TheDAO hack in 2016, it requires great engineering discipline and rigorous testing to bullet...

The first yield trading application on Linea is here! Splice Finance allows users to lock in and earn fixed yields or maximize points and variable yield from interest-bearing assets. Native yield trading allows users to split their yield-bearing tokens into two distinct components: Principal Tokens (PTs) and Yield Tokens (YTs). This approach provides flexibility and maximizes earning potential by enabling users to choose between fixed and variable yields. Here’s how it works and what you need...

On July 30th, ENS domains launched on Linea, allowing users to begin switching their 42 character Ethereum wallet addresses to a human-readable domain. In this web3 industry-first, Linea became the first zkEVM Layer 2 to adopt the EIP-3668 standard in production. So far, 350K Lineans have registered and adopted ENS domains, with the majority of users coming from Linea’s PoH audience.Ethereum Name Services (ENS) is a decentralized protocol, governed by ENS DAO and relying on immutable and tran...

In web3, decentralized applications (dapps) have gained popularity due to their ability to provide secure, transparent, and trustless services. Some of the most popular types of dapps are decentralized marketplaces, which allow users to buy and sell items directly on the blockchain, eliminating the need for intermediaries. In this tutorial, we will build a simple marketplace dapp on Linea, a Layer 2 zkEVM technology that offers a scalable and cost-efficient environment while maintaining the s...

As Ethereum continues to grow, staking is crucial to enhancing blockchain scalability, fortifying DeFi through liquidity, and fostering cross-chain innovation in web3. Traditionally, staking on Ethereum means your ETH is locked up. While it’s playing an important role enhancing scalability and security, you can’t do much else with it. But like web3 at large, this model has evolved. EigenLayer, introduced on Ethereum in June 2023, has addressed some of these limitations by introducing restakin...

Welcome to the Linea Guild Games (LGG)! Throughout Culture SZN in July, Lineans voted for their favorite web3 communities on Linea. In the end, five winners emerged, crowned as the first ever Linea Guilds. Now, four of these projects are going head-to-head as guilds in a gaming and community-first experience. The nine-day challenge kicks off on September 18. Players will choose to join one of the four guilds and mint a companion to your Game7 avatar. This fox, penguin, or frog will serve as a...

Welcome to the incredible world of Linea Prover, a solution in blockchain technology that ensures data integrity and privacy through zero-knowledge proofs (ZKPs). The prover is the backbone of Linea, a Type 2 zkEVM that aims to maintain near-complete compatibility with existing Ethereum infrastructure while significantly improving transaction speed and reducing costs In this post, we will explore the complex components that make up Linea Prover, including arithmetization, Arcane, polynomial-I...

The blockchain trilemma, proposed by Ethereum co-founder Vitalik Buterin, states that blockchain systems can only choose two of three properties: decentralization, scalability, and security. This trilemma often means making trade-offs when developing and building web3 infrastructure. Data availability is crucial for all three sides of this triangle. It ensures that all network nodes can get the information they need to check transactions, reach consensus on new blocks, validate state transiti...

Linea’s progress on the path to decentralization is accelerating. As the web3 world’s fastest-growing zkEVM L2 blockchain, Linea has already brought widespread scalability and development to the ecosystem, powering a new generation of Ethereum builders and decentralized applications (dapps). Leading web3 builder, Status, is joining Linea as the first contributor outside of Consensys to Linea’s open-source code, marking a major stride on Linea’s decentralization roadmap. The technically and co...

Blockchain technology has revolutionized many industries, from financial markets to gaming. However, this web3 revolution is dependent on significant computational resources, making scalability a persistent challenge. This is especially true for Ethereum, the leading platform for decentralized applications (dapps). zkEVMs have been introduced as a solution that aims to tackle these scalability issues while upholding Ethereum's security and decentralization. Launched in 2023 by Consensys,...

For DeFi enthusiasts in web3, maximizing rewards often means navigating a labyrinth of liquidity deposits and staking protocols. Adding yield aggregators and liquid staking into the mix only complicates things further. So, what’s the real cost of these potential boosts?Smart Contract Risk: The Hidden PitfallsPicture a futuristic vending machine powered by blockchain magic. Insert your crypto, make your selection, and—bam!—instant gratification. This is the heart of a smart contract: code that...

While Linea Culture SZN has officially come to an end, its impact on artists, communities, and the overall Linea ecosystem lives on. For a month, Lineans rallied around their favorite artists, minting NFTs from 23 creators, with almost 1 million participants. As Linea progresses on its journey to decentralization, nurturing a dynamic network where users become part of diverse communities is a priority. This was a main driver behind Culture SZN, creating a platform for both established and ris...
