Respond to Vitalik's call for the first time, and take a quick look at L2 Redstone, a chain game that combines OP+Plasma

作者：Karen，Foresight News

Yesterday, Lattice, the team behind the full-chain open-source engine MUD, announced the launch of L2 Redstone, which is suitable for on-chain games and self-made worlds, and has now been launched on the Redstone Holesky testnet.

Redstone is a plasma-inspired Alt-DA chain built on top of the OP Stack. Plasma, a blockchain scaling solution, allows all data and computation to remain off-chain except for deposits, withdrawals, and Merkle roots.

It is worth mentioning that before Redstone’s official announcement, Vitalik Buterin published a long article “Vitalik: Ethereum scaling track is not only Rollup, why should we focus on Plasma?”, arguing that Plasma is still an underrated design space, which can completely bypass data availability issues and greatly reduce transaction fees.

What is Redstone and how does it work?

Redstone is the first Plasma implementation of the OP Stack, built by Lattice and Optimism for developers of on-chain games and autonomous worlds.

The main difference between Redstone and other OP Stack Rollups is Data Availability (DA). Redstone does not use the use of L1 Ethereum for DA, instead uses alternative DA providers and only publishes input commitments to L1.

And to ensure this data availability, Redstone has set up a separate data availability challenge (DA Challenges), which allows anyone (node) to challenge the availability of data corresponding to a given commitment on L1, and can check the commitment data and challenge the commitment on the Rollup input dashboard.

The node challenges the input commitment, and the DA provider publishes the input to L1, which increases the cost. As a result, Redstone requires nodes to pay a deposit that can solve the cost of the challenge when submitting a DA challenge, which is burned if the DA provider successfully solves the challenge, and returned to the challenge node if it fails. The purpose of this is to reduce SPAM challenges.

In this way, transaction costs can be significantly reduced (generally mainly L1 data fees) while inheriting the full guarantee of Ethereum.

Redstone’s currently released Redstone Bridge enables ETH transfers between the Holesky testnet and the Redstone Holesky testnet, with future expansions to mainnet and other asset classes (ERC20, ERC721, etc.).

Lattice: Heavyweight in the omnichain game

Lattice product development spans chains, execution layers, L2s, on-chain operating systems, EVM frameworks, tools, and applications. Among them, the complex Ethereum application framework MUD developed by Lattice is more mature, and the complexity of building EVM applications is compressed through a tightly integrated software stack in the full-chain field.

Lattice’s success would not have been possible without the hard work and support of her team members and contributors. Lattice Team and Number of Contributors The Lattice website lists 13 team members, and up to 58 contributors.

Lattice’s primary funder and incubator is 0xPARC, a research organization formed by Gubsheep, the initiator of the Dark Forest, and projects that 0xPARC funds, provides operational support, or otherwise participates in include Dark Forest, Lattice, ZKonduit, Index Supply, Zupass, ZFT, Hack Lodge, EthUniversity, and others. And 0xPARC is funded by donations from the Ethereum Foundation, Gitcoin, ETHGlobal, and more.

In the summer of 2022, Lattice promoters Ludens and Alius collaborated on zkDungeon, an on-chain game that blends board games and battle royale games, and later released MUD V1 based on the realization that building the operating system was a higher priority.

According to Github records, MUD adds conventions for organizing data and logic, and abstracts low-level complexity so that developers can focus on the functionality of the application. In other words, MUD standardizes the way data is stored on-chain. With this standard data model, MUD can provide all the network code to synchronize the contract and client state.

In 2022, Lattice also partnered with Optimism to release OPCraft, an on-chain clone of Minecraft, using MUD in a month and a half.

Currently, the Lattice team is working on MUD V2, which will provide developers with more flexibility in reading and writing to the blockchain. In addition to MUD V2, Lattice is also working on Sky Strife, a full-chain real-time strategy game (with an official testnet launch on November 27), as well as other MUD-related infrastructure products. Projects powered by MUD also include Primodium, a full-chain city-building game, and Word3, an on-chain Scrabble game.

On-chain gaming must be one of the potential areas driving mass adoption of Web3. As an important infrastructure and enabler of omni-chain gaming, Lattice is creating new gaming experiences through game engines, L2, and gaming applications.
