What Is Celer Network?

Celer Network is a scalable platform where anyone can build and utilize decentralized applications (DApps). Scalability is achieved by making nodes operate independently and making most transactions off-chain to reduce on-chain burden, also known as Layer 2 scaling. Celer Network achieves its off-chain scaling technique via its state channel solution.

A state channel refers to the process in which users transact with one another directly outside of the blockchain, or off-chain. It is a sidechain solution developed by the Celer Network team. A sidechain is a side blockchain linked to the main chain via a two-way peg, meaning that assets can be transferred to and from the sidechain and mainchain.

What is Celer Network used for?

The state channel allows parties to execute smart contracts off-chain. In addition, it can be used to support functions related to payments, auction bids, token exchanges, gaming, and more. With the state channel network, off-chain operation is prioritized to ensure faster and cheaper transactions. Additionally, on-chain responsibility is minimized to end-to-end payment for better scalability and fewer malicious attacks. The key components of the system include CelerPay, CelerApp, and Celer Node:

  • CelerPay is a payment channel that supports off-chain payment on on-chain verifiable states, utilizing on-chain smart contracts and an off-chain communication protocol.
  • CelerApps is a state channel that expresses application logic such as payment conditions. It also acts as a virtual contract for off-chain use by developers and future players. On-chain deployment happens when a dispute is issued.
  • CelerNodes join state channel networks, which enable off-chain payments to nodes within the network.

Celer Network utilizes its State Guardian Network (SGN), a decentralized sidechain to ensure off-chain security and usability for state channel users. It assists in solving off-chain issues such as losing off-chain states, malicious disputes, offline payment, and on-chain payment. In addition, it provides services involving channel state protection, payment, and app connectivity. SGN is also incentive-aligned through the CELR staking process to reward CELR stakeholders.

The SGN’s architecture consists of four components:

  • Mainchain contracts hold the CELR staking process by enforcing rules for fees, rewards, and penalties for network participants.
  • Delegators receive shares of SGN reward and service fees proportional to their stakes.
  • Validators that calculate reward distribution, trigger penalties, and receive rewards from delegators.
  • Users that pay service fees to mainchain contracts and submit a request to the sidechain.

What is CELR Token?

Celer Network’s native token is CELR. CELR is an ERC-20 standard token built on Ethereum. It was introduced within the Celer Network system as an incentive to provide stable liquidity and improve state connectivity for the Celer Network through staking. CELR token’s use cases include:

  • CELR token can be used to pay the service fee and transaction fee to off-chain service providers and additional services provided.
  • One can stake CELR in State Guardian Network and become a State Guardian to receive sidechain block rewards and service fees.
  • CELR also serves as a reward for users providing liquidity.

What Does Celer Network Offer?

Celer Network is a Layer 2 scaling platform where developers build fast, cheap, easy-to-use blockchain applications. It also offers various products in its ecosystem that seek to solve different challenges within the crypto world. These products include the cBridge and Layer2.Finance:

Celer Network’s cBridge

Celer Network launched the mainnet version of cBridge in July 2021. cBridge is an interoperable bridge that seeks to resolve the issues that come with multi-chain development. As multi-chain development progresses, it becomes more distributed over time, leading to trade-offs on latency, throughput, and security. These developments include various types such as Layer 1 blockchains like Ethereum (ETH) and Layer 2 scaling solutions like Optimistic Rollups and sidechains. Additionally, the transfer of assets becomes more and more expensive and slow.

cBridge resolves such issues by providing a network for cheap and fast asset transfers between Optimistic Rollups, Layer 1 blockchains, sidechains, and Layer 2 scaling solutions. According to Celer Network, operations across networks are performed 1 million times faster with cBridge and are completed within milliseconds. Currently, cBridge supports popular blockchains such as Ethereum, BSC, Polygon Network (MATIC), and Avalanche (AVAX). However, at the moment the bridge only allows transfers of stablecoins such as DAI, USDC, and USDT across these platforms.

Celer Network’s Layer2.Finance

Layer2.Finance is a platform that uses Optimistic rollups where users can access Ethereum’s DeFi landscape efficiently without incurring high transaction fees on Ethereum. On the platform, users can maximize their yields while keeping transaction fees low. Users can also move their funds between major DeFi protocols such as Aave (AAVE), Compound (COMP), and Curve (CRV). The platform currently only supports the Ethereum mainnet and the deposit and withdrawal of stablecoins. Users can deposit their stablecoins to the available DeFi protocols and earn rewards.

Unlike other Layer 2 solutions implemented by other DeFi platforms, Layer2.Finance seeks to avoid liquidity fragmentation. Liquidity fragmentation refers to funds being stored on various blockchains on different layers. As a result of this fragmentation, DApps cannot access most of the liquidity because they are isolated. With Layer2.Finance, users can transfer funds between different DeFi protocols and layers and manage them through a unified dashboard. However, the execution time is slower since the platform needs to batch transactions together for lower gas fees. Nonetheless, Celer Network is looking to improve execution time by fostering the growth of the user base and incorporating ZK-Rollup to bundle even more transactions together into one.

What Is the Future for Celer Network?

Since its launch, Celer has been able to forge alliances with big players such as StarkWare and Polkadot (DOT). Celer is collaborating with StarkWare to add a ZK Rollup solution to the Layer2.Finance platform through StarkWare’s infrastructure. The collaboration intends to lower the user entry barrier and accelerate DeFi adoption for the mainstream. In addition, Polkadot just partnered with Celer Network to utilize the state channel network as a Layer 2 scaling solution to ensure fast and efficient asset transfers between parachains in Polkadot.

Currently, rollup solutions are adopted to improve on-chain throughput. However, the interaction has a long delay which results in a bad user experience. As a solution, instant cross-rollup and rollup-to-Layer 2 transactions with multihop capability will be adopted. In addition, Celer will also work towards supporting Layer 2 scaling to other major blockchains.

Besides checking for security bugs on Layer2.Finance, Celer will be integrating more DeFi strategies such as liquidity mining to acquire long-term users for Liquidity mining will reward more normal users for realizing the goal of mass adoption in the DeFi space.

cBridge will be also be integrating with other Layer 1 chains and Layer 2 networks as part of its development. As cBridge has bridged $1.2 million for users across BSC and Ethereum, more parties from various DApps, blockchains, and crypto wallets are increasingly interested in integrating cBridge for seamless asset transfer across chains. Some of the major wallets that have completed the integration include imToken and TokenPocket.
