Celer Network is a blockchain interoperability protocol that delivers a seamless, one-click user experience for accessing tokens, DeFi, GameFi, NFTs, governance, and more across various chains. Developers can create inter-chain-native decentralized applications (dApps) using the Celer Inter-chain Messaging Framework, which provides access to efficient liquidity utilization, synchronized application logic, and shared states. Users of Celer-enabled dApps can experience the advantages of a diverse, multi-blockchain ecosystem while enjoying the simplicity of a single-transaction user experience, all from a single chain.

Celer Network was established in 2018 by a highly skilled team of engineers with extensive technical expertise. The four co-founders of Celer hold PhDs in Computer Science from prestigious institutions such as MIT and UC Berkeley and have professional experience with leading technology companies. * Dr. Mo Dong earned his Ph.D. from UIUC. He served as a founding engineer and product manager at Veriflow, specializing in network formal verification. He is an expert in the application of algorithmic game theory to protocol design and instructs full-stack smart contract courses, with hundreds of students having graduated. * Dr. Junda Liu obtained his Ph.D. from UC Berkeley. In 2011, he joined Google to develop its datacenter networking infrastructure and later became a founding member of the Project Fi mobile service in 2014. He was also the Android Tech Lead for carrier services, operational on more than 1.5 billion devices. * Dr. Xiaozhou Li received his Ph.D. from Princeton University. His research has been published at leading conferences in distributed systems, networking, storage, and data management. His contributions have become integral components of Google TensorFlow, Intel DPDK, and Barefoot Deep Insight. * Dr. Qingkai Liang completed his Ph.D. at MIT. His research primarily addresses learning and control challenges in networked systems, particularly focusing on online learning algorithms in adversarial networks, which have been successfully implemented at Raytheon BBN Technologies and Bell Labs.

Celer significantly transforms the construction and utilization of multi-blockchain decentralized applications (dApps). Rather than deploying multiple isolated instances of smart contracts across various blockchains, developers can now create inter-chain-native dApps that leverage efficient liquidity utilization, consistent application logic, and shared states. Users of dApps enabled by Celer can experience the advantages of a diverse multi-blockchain ecosystem while enjoying the ease of a single-transaction user experience, eliminating the need for complex manual interactions across multiple blockchains. Celer employs smart contracts deployed on each chain in conjunction with the State Guardian Network, a blockchain based on Tendermint, to facilitate seamless multi-blockchain interoperability. To send a message or invoke a smart contract function cross-chain, a user or a dApp initially sends their intention as a message with a structured header and arbitrary binary payload to a Message Bus smart contract on the source chain. The State Guardian Network, acting as the validator, reaches a consensus on the message's existence and simultaneously generates a stake-weighted multi-signature attestation. This attestation is then relayed to the destination via an Executor that subscribes to the message. On the destination chain, an identical Message Bus contract verifies the validity of the message and executes the corresponding logic tied to the message, either immediately or after a designated timeout.

CELR has a maximum supply of 10 billion tokens, allocated as follows: 25% for PoLC mining rewards and off-chain ecosystem development; 20% for the team (18.3%) and advisors (1.7%); 17% for the foundation; 5% for marketing and ecosystem initiatives; and 33% for sale. CELR is an ERC-20 standard token developed on the Ethereum blockchain. It serves to manage the network's economy and has several applications: * Staking CELR in the State Guardian Network (SGN) to attain the status of State Guardian. State Guardians are responsible for status monitoring, responding to disputes, and ensuring security and efficiency within the network. * Staking CELR in the SGN or delegating it to SGN nodes to receive PoS staking rewards and transaction fee earnings sourced from Celer cBridge and Celer IM-based inter-chain decentralized applications (dApps). * Participating in and voting on network governance.

Celer's cornerstone—the State Guardian Network (SGN)—is a decentralized Proof-of-Stake blockchain that functions as a message router across various blockchains. SGN enables seamless message passing and cross-chain fund transfers while offering Proof-of-Stake security, rapid finality, and cost efficiency for applications utilizing Celer. Celer has successfully undergone three independent smart contract audits conducted by CertiK, PeckShield, and SlowMist. Additionally, Celer maintains a $2 million bug bounty program on Immunefi to incentivize community and whitehat contributions aimed at enhancing and securing the network.

The architecture of Celer Network is supported and secured by its proprietary blockchain, the State Guardian Network, which employs a variation of the Proof-of-Stake (PoS) consensus known as Delegated Proof of Stake (DPoS). This algorithm allows participants to stake their coins for rewards while delegating the responsibility of transaction validation to "delegates." The Celer State Guardian Network (SGN) is constructed on Tendermint and acts as a message router between different blockchains. Validator nodes are required to stake CELR tokens to participate in the SGN's consensus process. The CELR staking process is a fundamental element that underpins the economic security of the Celer Inter-chain Messaging Framework. To utilize the SGN's message routing service and store the multi-signature attestation, users are required to pay fees to the SGN. In addition to block rewards, these usage fees are distributed to CELR stakers and validators as compensation for their role in securing the network.
