Loom Network is an infrastructure platform dedicated to building the expansion of Ethereum. As a set of Ethereum second-layer expansion solutions officially launched, it is a DPOS side chain network, known as "Ethereum "EOS on top of" allows highly scalable games and user-facing Dapps to run on top of it, delivering the same high scalability and throughput promised by alternative platforms like EOS, while still being fully compatible with Ethereum and its security . Its core product is the software development kit tool Loom SDK, which allows developers to focus on writing application logic, and the SDK handles blockchain logic.

1. Project introduction

Loom Network is an Ethereum-based platform-as-a-service that allows developers to run large-scale decentralized applications. This allows developers to build DApps with the trust and security of the world's most secure public blockchain, and the computing resources needed to run commercial-scale services. Like Filecoin for tokenizing disk space, Loom aims to be the protocol for tokenizing applications for the new decentralized web.

Loom Network DAppChains

DAppChains developed by the Loom team are based on Ethereum's application-specific sidechain network, where developers can run decentralized applications at scale and the community can run software on sidechains. Each DApp runs on its own blockchain, and its data is public and forkable. Loom Network focuses on the "game" and "social" platforms on the Ethereum network, which is equivalent to separating the "game" and "social" functions from the congested Ethereum network.

Project Features

Solve the problems of Ethereum network congestion and low performance:
Loom Network solves the shortcomings of the Ethereum network through the side chain protocol, and this solution is basically compatible with other scaling solutions of Ethereum such as Raiden, Plasma, etc. coexist.

Solve the problem of non-isolation of resources:
The entire DApp running on Loom's DAppChain will run on a decentralized blockchain to meet the needs of decentralized applications in reality without being overwhelmed Ethereum network, to avoid the recurrence of the ether cat incident.

Solve the problems of virtual asset depreciation, fairness, lack of reputation and trust in traditional games:
Blockchain technology uses distributed accounting and smart contract technology to make random number generation programs and automatic reporting systems no longer controlled by Instead of being managed by people, it is managed through encrypted and verifiable codes, which will greatly increase the level of trust, thereby adding value to the online interactive game industry and improving the original ecosystem.

Application scenario

Loom Network is currently focusing on games and social applications:
Games - Create games that only blockchain can achieve: verifiable scarce items, tradable tokens, eternal worlds, multi-game across the universe< /p>

Social——Get rid of the shackles of social applications that can only be driven by advertisements, and can make money through Karma tokens, expand through multiple clients, and reduce cumbersome authentication processes.

Technical Overview

Loom Network uses sidechain technology to enable large-scale and high-throughput applications to be built on Ethereum. Loom uses Ethereum as its main chain, and developers can easily build DApp chains through the Loom SDK. Each Dapp chain is a Loom side chain. And it can allow side chain platforms similar to EOS to appear, and multiple Dapps can be built on one side chain, such as the zombie chain (zombiechain) currently developed by the Loom team.

Introduced in 2014, sidechain technology is defined by a custom "rule set" that can be used to offload computation from another chain. Each sidechain can follow different rules from the main chain while still relying on the main chain for requests requiring the highest level of security. The Loom team currently positions Dapp products on social platforms and games. When decentralization, security, and high scalability cannot be satisfied at the same time (The Scalability Trilemma), the best performance can be achieved by sacrificing part of security. At the same time, the weakening of security is compensated by the economic incentive mechanism in a specific environment, such as tampering with a certain blog information or a certain game transaction with extremely low income and becoming unworthy. And the Loom ecosystem will support free forks. If a sidechain is controlled by a group, the community can choose to collectively migrate to the new sidechain.

At the value transfer level, all of these Loom sidechains use Ethereum as the supreme court, using Plasma Cash for security. Loom Network claims to be the first team to integrate Plasma at the level of developing DAppchains. The Plasma Cash implementation consists of a Plasma smart contract that lives on the Ethereum mainnet and a Loom sidechain smart contract that communicates with the Plasma contract. The user first sends his tokens to the Plasma contract. After receiving the tokens, the Plasma contract sends a Deposit event, which is received by the listening sidechain. Users are then given a special Plasma Cash token on the sidechain that represents their ownership of that token on the mainnet.

The sidechain periodically "archives" to the mainnet by submitting the Merkle root of the block to the Plasma contract, showing any changes in token ownership. When there is a security problem on the side chain, the user can submit an exit request directly to the Plasma contract on the main network, and then the token enters a "challenge period", in which the challenger can submit evidence of a signed transaction, proving that the user trying to exit the token is not its effective owner. If the challenge period is not successfully challenged, users can withdraw their tokens from the Plasma contract.

Two. Comments

Loom Network DAppChains, born for games and social applications. This is all built on a forkable, decentralized, and readable blockchain rule set. Dapp chains are a blockchain with all the features that run on Ethereum smart contracts. Each dapp runs on its own blockchain, and its data is public and forkable, just like Ethereum and blockchain. Loom Network provides an INFURA-like caching layer that makes everything simple, and at a lower level, it is a very pure blockchain: forkable, trusted, efficient, and scalable.
