Project Overview

What does the company/project do?

Celer Network aims to be the first off-chain operating network to bring Internet-level scalability to blockchains. It can scale out to billions of trust-free, secure, and private off-chain transactions per second.

Because transactions are processed off-chain by only those involved, the network’s throughput can increase almost linearly even as more nodes and applications are added to the network.

The team stands behind their off-chain solution to blockchain scalability. In their view, on-chain consensus improvements such as sharding and various Proof-of-X may make the blockchain relatively faster. However, on-chain consensus has its fundamental limitations, making it difficult to achieve Internet-level scalability (i.e. billions of transactions per second).

Celer Network is being designed to serve as an entry point for scalable decentralized applications (dApps) with a simple, user-friendly interface. For users, connecting to Celer Network could potentially be as easy as connecting to the Internet. With Celer Network’s proposed technology, blockchain applications could become more scalable and achieve mass adoption.

Celer Network’s technology architecture is called the cStack, a four-layered architecture which is based on the design principles and architecture that made the Internet successful. The cStack is comprised of: 

  • cApps: The network’s application ecosystem, which is designed to be scalable and privacy-preserving. The team has already developed one working cApp.
  • cRoute: A protocol used to route generalized states, such as conditional payments, in a trust-free manner between users. According to the team, this will enable 15x higher throughput compared to other solutions, such as the principle used in Raiden and Lightning’s routing algorithms, with high failure resilience.
  • cOS: A development framework and runtime for scalable off-chain dApps that handles the operation, storage, tracking, and dispute of off-chain states.
  • cChannel: A generalized state channel and sidechain suite that supports fast state transitions and maximizes liquidity utilization. This essentially means that Celer could go beyond supporting simple payments to various other applications including gaming, online auctions, insurance, prediction markets, and decentralized exchanges.

This diagram shows the various components of Celer Network four-layered architecture, called the cStack:

Here is the video demo of the Celer Network MVP, which showcases the project’s first scalable off-chain mobile cApp: cGomoku, a Gomoku duel game (video is 15:49 long):

What are the tokens used for and how can token value appreciate?

The CELR token is the network’s native protocol token and will be used in various ways within Celer Network to bring value and provide network effect and stable liquidity. In addition to its use as the platform currency, uses for the CELR token will include the following:

  • Proof of Liquidity Commitment (PoLC): The network features a virtual mining process that acquires liquidity for the off-chain ecosystem in order to maintain a stable and abundant liquidity pool. To participate, users will need to commit/lock their idle liquidity for a certain period of time and in exchange, will be rewarded with CELR tokens.
  • Liquidity Backing Auction (LiBA): This auction process enables off-chain service providers to solicit liquidity from lenders, which are ranked based on their interest rate, amount of provisioned liquidity and amount of staked tokens. For lenders, this means that the more CELR tokens they stake, the higher their rank/priority.
  • State Guardian Network (SGN): Before a user goes offline, he/she can submit their state to the SGN and request it to be guarded for a certain period of time for a certain fee. To become a stake guardian, CELR token holders need to stake their tokens in order to earn guarding opportunities and service fees. The more tokens that are staked, the more service fees will be earned by the stake guardian.

CELR tokens should appreciate in value as more users join and use the network. This is driven by numerous factors, including the number and type of applications available on the platform, ease of use, transaction speed, etc.

Other uses of the CELR token (i.e. PoLC, LiBA and SGN) incentivizes users by providing various rewards and fees, which should also help increase the demand for the token and therefore, its value.

  • Celer’s generalized state channels are better and more efficient than other projects tackling the same problem. It has demonstrated to be 15x faster with a much higher channel utilization ratio because of the channel balancing mechanism.
  • The founders have a very strong technical background, particularly in computer networking infrastructure, formal verification, etc., with prior experience working at major tech companies including Google, Intel, Microsoft, and Nokia Bell Labs.
  • Celer Network is blockchain agnostic and can be integrated with any blockchain, therefore the risks of the project becoming obsolete due to the blockchain that it is integrated with have reduced substantially.
  • The staking mechanism makes the network more efficient and provides good token utility. 


  • No business development or go-to-market strategy has been provided yet but this is a crucial factor in achieving and sustaining mass adoption.
  • The project faces competition from other off-chain payment networks include Raiden, Lightning Network, Funfair, Perun Network, and others. 


Our thoughts of the tokens for short term and long term are as follows:

For short-term holding: A

Considering the detailed token metrics, including the lock-up terms for private sale, we believe the project offers great short-term potential.

For long-term holding: S

We really like the long-term prospect of the project. In fact, we believe Celer is one of the most technically advanced projects that we have looked at that is led by a capable team.

We believe on-chain and off-chain scaling solutions are both needed to take decentralized applications to mainstream. No matter how robust on-chain scaling solutions become, the latency is still far higher than off-chain solutions. We believe end users care about user experience more than anything else.

Celer, being blockchain agnostic, has a much higher chance to succeed than projects that are only compatible with a single blockchain. We also like how CELR tokens help the network to become more efficient. Therefore, we believe CELR tokens have a great long-term potential.

Disclosure: We intend to enter into a position in this project.
