Everything You Need to Know About Celer Network (Updating Regularly)

14 min read

Last updated on Oct 17, 2019

Celer Network came out of stealth in Q3 2018. Though it is only less than a year, we have made so many achievements and progresses. It is without a doubt that Celer is leading the charge in the red-hot area of layer-2 scaling. We hear community’s feedback that it is sometimes hard to keep track of what has happened and what is happening right now. Thus, we decided to create this post where you can always come back to and find what you’re looking for. Think of it as a “one-stop-shop” for everything you want to know about Celer Network. This article will be updated regularly!

1. What is Celer Network?

Celer Network is the most advanced layer-2 scaling platform to build fast, easy-to-use, low-cost and secure blockchain applications at internet scale. Celer was founded by experienced entrepreneurs with PhDs degrees from MIT, Princeton, UC Berkeley and UIUC and has a fast-growing all-star team with years of engineering, product, user growth and marketing experience from tech giants like Google, Amazon, Cisco, Oracle, HP and more.

At its core, Celer is a layer-2 infrastructure on top of blockchains, the ecosystem also includes dApps and cryptoeconomic models to incentivize usage of our layer-2 scalability solution.

We continue to lead the technology innovation in the space of off-chain (or “layer-2”) infrastructure with many of the world’s first: we led the cutting-edge research and development of layer-2 scaling; we delivered the world’s first and most advanced generalized state channel network Testnet; we released CelerX: the first-ever mobile application that can access layer-2 dApps; we released first-ever mobile native layer-2 scaling SDK; we delivered on our promise to become the world’s first blockchain agonistic layer-2 scaling platform by supporting two architecturally very different blockchains, Ethereum and DFINITY, at the same time.

What are Layer-2 scaling platforms?

Layer-2 scaling platforms are built “on top of” the layer-1 blockchains like Ethereum and Bitcoin. They do not require changes to the base level protocol — rather, they exist simply as smart contracts on main-chain like Ethereum that interact with off-chain software.

What are the core technologies behind Celer?

Celer focuses on Generalized State Channel Network and Side Chain technology. It provides a coherent architecture with It enables smart contract on layer-2. To know about the underlying technology, please read our white paper. We also have a more reader-friendly summary here. To dive a bit deeper into deeper, please check out this explanatory article about Celer state channel and this three-part blog series about generalized state channel (Part 1: What Are They Good For? Part 2: How do you use state channels in a dapp?). Long term, Celer Network’s vision is to combine all layer-2 scaling technology pieces together into a coherent solution.

One simple analogy we can use is that if you compare Celer to Lightning, it’s like comparing Ethereum to Bitcoin. Ethereum introduced the general smart contract functionality layer-1 blockchain and Celer introduces the general smart contract flexibility on layer-2.

Where we are on the testnet/mainnet roadmap?

a) Alpha-Mainnet

Celer Network’s alpha-mainnet launched on July 7th, 2019. The alpha-mainnet, Cygnus, marks the beginning of the world’s first Generalized State Channel Network, starting from Ethereum. It opens up an entirely new dimension of blockchain layer-2 scalability with real-time and zero-fee interaction, instant micropayments and low-latency interoperability for decentralized Apps.


b) Testnet

Two testnets have been successfully launched so far:

1. Oct.2018:Testnet Centauri with cWallet, the first reference wallet integrated with Celer Network mobile native SDK and Centauri Testnet

2. Feb.2019:Testnet 2.0, Sirius with CelerX, the FIRST AND ONLY layer-2 application platform on iOS and Android.

We’ve shared our testnet experience and results during EDCON 2019

2. Celer’s Cryptoeconomic Model and CELR token

Celer’s Crypto Economic model (cEconomy) is a staking system that provides security, stable and abundant liquidity, and state connectivity for the Celer Network.

We introduced the first-ever layer-2 crypto economics cEconomy with the CELR token playing a central role. cEconomy is a staking-based system that provides security, stable and abundant liquidity, and state connectivity for Celer Network. To give a high-level summary:

  • CELR token can be used to pay the service fee and transaction fee to off-chain service providers and additional service provided.
  • One can stake CELR in State Guardian Network and become a State Guardian. State Guardians perform services like state monitoring, dispute response and connectivity to protect the security and improve the efficiency of Celer Network. During the service process, State Guardians receive service fee and side-chain block rewards.
  • CELR also serves as an incentive for maintaining a stable and abundant liquidity pool in Proof of Liquidity Commitment process.
  • CELR can also be used in Liquidity Backing Auction to increase the priority of liquidity backing bids and therefore statistically increase the liquidity interests payout.

Interested in learning more on cEconomy? We’ve also published a series of “How to Use CELR Token?” videos on Celer’s Youtube Channel.

We’ve finished our token sale on March 19, 2019, with Binance Launchpad. You can refer to Binance Research report on CELR token for more detailed token sale and economics information.

3. How is Celer different from other layer-2 scaling solutions?

To help everyone better understand the difference between Celer and other layer-2 scaling solutions, Binance did an independent research report and here is what was found.

Competitor Overview (Key comparables)

Celer Points of Differentiation

  • Multi-blockchain support
  • Support not only payments but also off-chain smart contracts
  • Provably optimal state routing algorithm with more than 20X performance gain
  • First and only off-chain crypto economic model to provide state availability, connectivity, dispute resolution and abundant liquidity for off-chain scaling platform, where CELR token plays an indispensable role.

4. What is CelerX?

Our consumer-facing product, CelerX is the FIRST AND ONLY layer-2 application platform on iOS and Android. Backed by the most advanced off-chain scaling platform, CelerX users can transfer instant and zero-fees payment through Celer Pay, and play diverse skill-based games. Since July the 8th mainnet launch, CelerX has reached $1.4M+ total prizes awarded, 11K players and 300K matches from 88 countries.

You can also find A series of State channel research calls we’ve been hosting with other top researchers in the area at Celer’s Youtube Channel. On August 26, 2019, together with other state channel projects we’ve announced an initiative to unify Ethereum’s State Channels projects around a single standard. Our goal is to enable the best possible user and developer experience for State Channels. All wallets, clients, or applications that use the State Channels specification will be compatible by default. Developers and users will not need to worry about supporting a multitude of competing standards, avoiding fragmentation.
