Celer Network (CELR)
A Interoperability Protocol For Cross-Chain Fund and Message Transfers.
Share this article
Celer Network is an interoperability platform that supports cross-chain fund transfers and generic message passing.
CELR is the native token of the project. The current use cases include:
Staking: Users can delegate CELR to stake with validators to participate in the network consensus, and in return are rewarded with CELR.
Network Fees: Celer stakers on the SGN can share the value captured by the State Guardian Network when the network sync, store, and sign messages.
The project consist of the following major components:
State Guardian Network (SGN): A Proof-of-Stake (PoS) blockchain built on Tendermint with CELR as the staking asset, and offers L1-blockchain level security.
Celer cBridge: A cross-chain asset bridge, which support over 20 networks including Ethereum, BNB Chain, Polygon etc. The cBridge SDK allows new and existing applications to integrate features that are available in the cBridge.
Celer Inter-chain Message (IM): A Framework that supports generic message passing and cross-chain function calls. Developers can build inter-chain-native dApps using the Celer Inter-chain Message SDK to gain access to efficient liquidity utilization, coherent application logics, and shared states.
As at April 29th 2022, the total and maximum token supply of CELR is 10,000,000,000, and the circulating supply upon listing will be 6,840,000,000 (~68.40% of the total token supply).
1. What is Celer Network (CELR)?
Founded by four PhDs from MIT, Princeton, UC Berkeley and UIUC, Celer Network is an interoperability platform that supports cross-chain fund transfers and generic message passing.
Celer enables anyone to easily build inter-chain-native dApps using the Celer Inter-chain Message SDK to leverage efficient liquidity utilization, coherent application logic, and shared states, while users of Celer-enabled dApps can access a diverse multi-blockchain ecosystem with the simplicity of a single-transaction UX.
The Celer State Guardian Network (SGN) is a Proof-of-Stake (PoS) blockchain built on Tendermint that serves as the message router between different blockchains.
Validator nodes stake CELR tokens to join the consensus process of SGN. The CELR staking process is a crucial part of the economic security of the Celer Inter-chain Message Framework and Celer-enabled dApps like Celer cBridge.
To use SGN's message routing service and to store the multi-signature attestation, users must pay a fee to SGN for these services. These usage fees are distributed to the CELR stakers and validators for their work in securing the network on top of regular PoS block rewards
2.2 Celer cBridge
The Celer cBridge is a decentralized and non-custodial asset bridge, which allows users to transfer a variety of tokens across different blockchains in a fast, secure and low-cost fashion. It currently supports 100+ tokens across 30+ blockchains and layer-2 rollups. Built on top of the Celer Inter-chain Message Framework, cBridge has processed over $6B cross-chain asset transfer volume on 30+ blockchains for more than 140K unique users, and is quickly growing and expanding into more blockchains and layer-2s.
In July 2021, cBridge v1.0 was launched to support token transfers between Ethereum, Arbitrum, Polygon and BNB Chain. Transfers were enabled by liquidity provided by node runners.
In November 2021, cBridge v2.0 was launched on mainnet with support extending to over 80 tokens and over 20 blockchains and rollups. Transfers are enabled in two models, one requiring liquidity and the other via canonical mapping. With the two models, Celer fulfilled the goal of supporting different token deployment scenarios.
By the end of March 2022, Celer cBridge has surpassed $5.3B in total transaction volume, serving over 120K unique user addresses.
2.3 Celer Inter-chain Message Framework
Launched in January 2022, the Celer Inter-chain Message Framework (Celer IM) supports generic message passing and smart contract calls across different blockchains. With Celer IM, developers can build inter-chain-native dApps with efficient liquidity utilization, coherent application logic, and shared states. Users of Celer IM-enabled dApps will enjoy the benefits of a diverse multi-blockchain ecosystem with the simplicity of a single-transaction UX.
By making cross-chain composability possible, the Celer IM framework opens up an entire galaxy of opportunities for inter-chain-native applications like cross-chain DEXes, yield aggregators, NFT marketplaces, metaverse games, NFT bridges, etc.
Celer IM uses smart contracts that are deployed on each chain paired with the State Guardian Network in order to enable seamless multi-blockchain interoperability.
To send a message or invoke a smart contract function cross-chain, a user or a dApp will first send their intention as a message with a structured header and arbitrary binary payload to a Message Bus smart contract on the source chain.
Then the validator, the State Guardian Network, will first reach a consensus on the existence of such a message and concurrently generate a stake-weighed multi-signature attestation.
This attestation then is relayed to the destination via an Executor subscribing to the message.
On the destination chain, the same Message Bus contract exists to check the validity of the message and triggers the corresponding logic associated with the message either immediately or after a timeout.
Layer2.finance was launched in April 2021, and was built to tackle the two largest challenges preventing DeFi from reaching mass adoption: (i) The extraordinarily high transaction fees, (ii) Being very difficult to navigate and use.
Layer2.finance is a novel solution that allows people to access all existing DeFi protocols at a fraction of the cost by acting like a “DeFi Public Transportation System”.
