Celer Network (CELR) is a cleverly designed second-tier extension solution that provides off-chain transaction processing. The Celer platform provides fast, easy and secure off-chain transactions for payments and smart contracts. The project is one of the first to be developed using Substrate framework and is part of the Polkadot ecosystem.

Celer Network is committed to building a blockchain application portal platform matching the scale of the Internet based on off-chain expansion technology, so that all people can develop, run and use high-performance distributed blockchain applications conveniently and quickly on this platform.

The first-layer blockchain, such as Bitcoin and Ethereum, has poor scalability, easy network congestion and poor user experience.

Celer Network is a common state channel and side chain suite that supports fast and common out-of-chain state transitions; An efficient state channel payment routing protocol with an order of magnitude increase in throughput compared to state-of-the-art solutions; A hybrid summary side chain that provides user adjustable trade-offs in trust, performance, and functionality; A powerful development framework and runtime for off-chain applications; And a new crypto economy model that provides strong security, high availability, stable liquidity and network effects for the off-chain ecosystem.

Celer Network employs a coherent and loosely coupled architecture with clear abstractions that enable rapid evolution of each individual component.

Pay commissions for services and transactions to non-chain suppliers and pay additional fees. Lock CELR into the status guardian Network (SGN) and acquire status guardian status. The status guardian has the authority to monitor status, respond to disputes, and provide security and network efficiency. CELR tokens maintain substantial liquidity during the Proof of Liquidity Commitment (PoLC) process. CELR tokens can be used for liquidity support auctions (LiBA) to increase the priority of liquidity support applications, thereby increasing the payment of liquidity interest.

Proof of Shareholding (PoS) consensus variant of DPoS. With this algorithm, participants can bet their coins to win a prize, while shifting the responsibility of verifying the transaction to the "representative".

Celer is a networked system, not a standalone blockchain. The platform runs on top of existing and future blockchains. Developers are focusing on scalability to increase throughput of the cryptocurrency blockchain. The Celer team sees no internal solution to the decentralized blockchain of the future, but rather an off-chain platform to solve the problem.

Celer Network's architecture (cStack) is built on four elements: 1) cOS: the Network core that provides workflow. 2) cRoute. A mechanism that allows increased operational capability by streamlining routes within a network. 3) cChannel. A channel for transmitting transactions over a network. 4) cApps. An ecosystem application layer for extension and user privacy.

CELR has a maximum supply of 10 billion tokens, which are distributed as follows. 25% - PoLC mining incentives and off-chain ecosystem building; 20% - Team (18.3%) and consultant (1.7%); 17% - Foundations; 5% - Marketing and ecosystem; 33% - Sales.

Celer's highlight is that the platform allows for a second layer of extension on any blockchain. As a result, the program covers a wide range of markets, doubling liquidity potential and improving product reliability, coverage and adaptability. The four layers of the cStack architecture are evenly divided to provide several unique advantages. These advantages include: reduced transaction delays; Reducing commissions for small payments; Zero commissions in working off-chain smart contracts; Horizontal expansion of new nodes; Provide out-of-chain models for cryptoeconomics; The optimal routing algorithm for transactions; And support for various blockchains. CEconomy is a unique crypto economy model responsible for maintaining stable liquidity and availability for ecosystems while creating network effects. Mining algorithms do not require proof of work (PoW). Users simply install the software and keep CELR in their accounts to earn income as a reward for providing liquidity.

CELR holders are rewarded for providing liquidity.

As one of the leading tier 2 extension platforms, Celer incorporates a number of unique features that help differentiate itself from its competitors. These include support for a variety of different extension solutions, including Optimistic Rollups, and generalized State Channels, with the potential to support other solutions in the future, This may include Plasma, Validum, and ZK-rollup.

Positioned as an off-chain scalable solution, the project aims to bring Internet scale to blockchain. A new technical solution and economic model are proposed based on the traditional off-chain solution, and the experimental simulation results show that the performance of this solution is improved by order of magnitude.

The project development team has excellent strength, and is guided by famous researchers from famous universities and famous development engineers, which is expected to make breakthrough progress in off-chain scalability. However, state channels also have natural limitations, such as being more suitable for high-frequency interactions with multiple users than for low-frequency interactions where users change frequently. Even so, as the extensibility enhancement suite of the public chain, the off-chain state channel, once successfully broken through, will be conducive to promoting the practicalization of blockchain.

Smart contract vulnerabilities, competition with other public chains, scalability solutions.

Celer allows for a second layer extension of any blockchain. As a result, the project covers a wide range of markets, doubling the liquidity potential, providing broad coverage and long-term prospects.
