What is the difference between Paradigm to develop L2 in person?

Written article: 0xjs@：

Although there are already N Mao Ethereum L2, the new big players are still entering the Ethereum L2 battlefield.

UNISWAP on October 9, 2024 announced that it would develop its own L2 Unichain.On the same day, Paradigm announced that he invested 20 million US dollars to iTHACA, and iTHACA has launched the L2 test network Odyssey.

It is worth noting that iThaca and Odyssey can be described as Paradigm.Paradigm CTO and ordinary partner Georgios will lead the ITHACA team as CEO. Paradigm founder Matt Huang will also join the iTHACA team and serve as the chairman of iThaca.

Paradigm to push iThaca what to do

According to iThaca’s official website, iThaca is a company that aims to accelerate the frontiers of encryption technology.ITHACA believes that encrypted technology must develop faster, and for this reason, it raised $ 20 million to accelerate the development of the entire stack.

IThaca said its first step was Odyssey.Odyssey is an open source L2 test network from the future, built by RETH, OP Stack, and ConduitEssence

Ithaca also saidBuilding Odyssey is to promote the innovation of a wider range of infrastructure ecosystems. It plans to reshape new features frequently, called chapterEssenceEach Odyssey chapter is similar to the development network, and new features will be launched. There is a limited duration and will not maintain the status between each chapter.

ITHACA also announced that Odyssey Chapter 1 has been launched online on SEPOLIA.

What does Paradigm push iThaca to do?ITHACA bluntly stated that “Crypto Must Go Faster”, its goal is to help other L2 accelerate cutting -edge technology.This move is considered by industry insiders to be “developers to make princes.”

Why do you say that?Please see Odyssey Chaprter 1.

Odyssey Chapter 1

Odyssey Chapter 1 has the following features:

High performance, stability and scalability through RETH SDK
The new features of the two upgrades of PECTRA and Fusaka in the next two upgrades of Ethereum are currently: EOF, EIP-7702, EIP-2537, RIP-7212.
Enter L2 without friction, users do not need to understand custom RPC, bridge ETH or browser extensions.

RETH SDK: Realize high performance, stability and scalability

Odyssey is built with RETH SDK.The RETH performance created by Paradigm is excellent, stable and scalable.Reth is not a L1 node or a L2 node, but a library for building a high -performance, stable and scalable encrypted service, which can be called RETH SDK, which allows iTHACA to use a small team at a record speed.Launched Odyssey.

Reth SDK can bring to Odyssey:

Inherited the high throughput and low -writing delay of RETH.
Inherited the RETH’s fast archive node and RPC reading function.
Due to the same code of shared running Ethereum main network, it inherits the stability of Reth.
Due to the scalability of RETH, it is very simple, & lt; 1000 LOC of Rust; including testing.

Odyssey’s goal is to 33 mega GAS per second (200 mega GAS in OP Stack, 6 elastic coefficients), the block time is 1 second, and the iTHACA plan will then increase its target GAS to the Gigabit per second.ITHACA also plans to cooperate with the ecosystem to launch new cutting -edge functions.

Paradigm said that he was very happy to continue to promote the cutting -edge of the encryption infrastructure in the next few months, and RETH SDK is an important tool for achieving this goal.

Experience the functions of Ethereum in advance to upgrade PECTRA and FUSAKA

The next two upgrades of Ethereum Network are Pectra and Fusaka, which will bring many exciting new features to the Ethereum main network.But developers do not have to wait until these features are launched and tested them.

Paradigm said,A lot of EIPs have been implemented and tested in PECTRA and Fusaka, which have been released, and they have been published in Odyssey Chapter 1 for developers to build them.

So, what EIP does Odyssey Chapter 1 contain?Specifically, Odyssey includes:

EIP-7702: Paying the road for account abstraction, which will completely change the user experience on the chain.This EIP introduces a new type of transaction that allows external accounts (EOA) to run like smart contracts.This has unlocked functions such as GAS sponsorship, account recovery, trading bundling or limited authority to awarded the sub -key.
EVM object format (EOF): represents a series of EIP designed to improve EVM.EOF introduces EVM bytecode to the version of the container format, thereby achieving a safer, more efficient and more friendly smart contract for developers.EOF particularly makes smart contracts saving GAS, easy to analyze static analysis, and eliminates the infamous “Stack Too Deep” error in Solidity.
EIP-2537: Implement pre-compilation of BLS12-381 in order to perform encrypted operations on the BLS12-381 curve.This EIP aims to improve the operational efficiency used in protocols such as BLS signature aggregation and zero knowledge certification.
RIP-7212: Introduced pre-compilation of the SECP256R1 oval curve, which is widely used in protocols such as Apple Secure Enclave and Webauthn.The curve allows users to store private keys in the hardware module and use biological characteristics to sign messages.Pre -compilation can directly verify these signatures directly on the chain. Compared with the traditional method of pre -compilation, the GAS cost can be reduced by up to 50 times.This is available on most OP Stack chains, but it has not been widely used.

Enter L2 without friction

By using EIP-7702, RIP-7212 and the new EIP-5792 Wallet_ RPC naming space (allowing sorters to sponsor transactions), Odyssey allows users to enter the Odyssey L2 test network without installing wallets, no GAS tokens, no need to and bridge.Interaction does not need to set up a new RPC.This is applicable to cross -device and cross -application programs, using the key string or password manager of the user operating system.

IThaca provided on the official website>InstanceEssenceIn the instance provided by the official website,Just click “Create”, without the need to expand or embedded wallet, you can create a smart contract wallet containing the test network tokens with the signature of the Passkey signature(Note: You need to support the Passkey device).It uses EIP-7702 and RIP-7212 to send sponsorship transactions to cast 100 EXP ERC20 token with cast experiments. All operations only need to click once.

You can also directly click the “SWAP” button to exchange the EXP test to the Odyssey test network ETH at a fixed ratio of 1: 1000.No bridge, no RPC, no need to deposit in ETH in advance as GAS feesEssencevice versa.

IThaca next plan

IThaca bluntly stated that its future plan is to help other L2 accelerate the use of cutting -edge technologyThis work has been launched in the cooperation between many companies such as Paradigm and Optimism, Uniswap, Conduit, Flashbots, SUCCINCT, Base.

Some of these tasks will be completed by iThaca, and most of them will promote the innovation of others, such as existing collaborators or broader encryption ecosystems.

Some wider areas that iThaca pays attention to includes::

Wallet final: What ideal functions should wallet have?How to operate from entering, bridge, exchange, signature aggregation, account recovery, light client verification, etc.?
Accelerate the decentralization of the second phase of the OP Stack’s route map, making each rollup a ZK Rollup.
Use Tee and other emerging technologies to improve the MEV market structure.
Deploy front -edge encryption technology and applications that support encryption: ZKPASSPORT, FHE, ZKEMAIL, TLS Notary, etc.
Accompanation and privacy standards in the scope of ecosystems.
Experimental EIP of the frontier researchers and developers: surprise us!
Through parallelization, compilation byte code, block-level access list, new EOF version, smart contracts using RISC-V ISA to innovate in the VM layer.
The new GAS cost structure (such as multi -dimensional GAS) supported by strict data -driven benchmark test.
High -performance system engineering is committed to breaking the obstacles of GAS per second GAS through new state status (such as Verkle Tries), databases, networks, and consensus.
