DeFi Insight: Cresent Network — the hybrid DEX

What makes Cresent different?

In 2020 we saw the rise of DeFi, which was led by AMMs like Uniswap. These protocols became very popular with certain use cases. AMMs weren’t the first DEXs on Ethereum. One of the first DEX protocols was EthereEx which uses an on-chain order book. It quickly became clear that such a design would not work. Users had to pay a fee to the Ethereum network for every action, including placing and canceling orders. This made it cost-prohibitive for users, in particular market makers, who often make 100x as many orders as executed trades. Every action had to be mined by the Ethereum network, which meant delays until the next block was mined. After the fall of order books, AMMs dominated the space. While very good with certain use cases, there are limits for traders on AMMs: users can’t place limit orders or market orders. Cresent wants to offer users a taste of both worlds.

Relationship between Liquidity Pool and Order Book

Crescent Network utilizes the concept of an order book. For each coin pair, the protocol creates an order book. Users can then submit both limit and market orders. Liquidity pools also participate in the order book. A liquidity pool becomes an AMM, which allows investors to participate in the market-making by automatically making orders in the order book for the coin pair. In essence, each liquidity pool acts like another market participant in the order book. It calculates groups of limit orders for each tick then all integrated orders on the order book are matched to each other at once.

Other features

Miner Extractable Value(MEV) on Ethereum has been a growing problem for traders. Crescent tries to minimize MEV by adopting a method called batch execution for the order book. In batch execution, orders within a batch are treated equally without any sort of prioritization. It brings healthy competition among arbitrageurs and traders, which results in more efficient price discovery of the order book. Crescent will also include concentrated liquidity, just like in Uniswap v3. By providing liquidity within a finite range of the current price, the network can supply the same liquidity within the range as the basic pool with an infinite range, resulting in the same trading experience for users. Crescent Network also introduces the concept of liquid staking. Once a user stakes CRE through the liquid staking module, the staked CRE is locked, but the user receives bCRE (pegged staked representative tokens) instead. When the delegators want to unstake bCRE, the module will burn the bCRE and give them CRE back, which will be a larger amount of CRE thanks to the liquid staking rewards during the delegation period.

The International Token Standardization Association (ITSA) e.V.

The International Token Standardization Association (ITSA) e.V. is a not-for-profit association of German law that aims at promoting the development and implementation of comprehensive market standards for the identification, classification, and analysis of DLT- and blockchain-based cryptographic tokens. As an independent industry membership body, ITSA unites over 100 international associated founding members from various interest groups. In order to increase transparency and safety on global token markets, ITSA currently develops and implements the International Token Identification Number (ITIN) as a market standard for the identification of cryptographic tokens, the International Token Classification (ITC) as a standard framework for the classification of cryptographic tokens according to their inherent characteristics. ITSA then adds the identified and classified token to the world’s largest register for tokens in our Tokenbase.

  • The International Token Identification Number (ITIN) is a 9-digit alphanumeric technical identifier for both fungible and non-fungible DLT-based tokens. Thanks to its underlying Uniform Token Locator (UTL), ITIN presents a unique and fork-resilient identification of tokens. The ITIN also allows for the connecting and matching of other media and data to the token, such as legal contracts or price data, and increases safety and operational transparency when handling these tokens.
  • The International Token Classification (ITC) is a multi-dimensional, expandable framework for the classification of tokens. Current dimensions include technological, economic, legal, and regulatory dimensions with multiple sub-dimensions. By mid-2021, there will be at least two new dimensions added, including a tax dimension. So far, our classification framework has been applied to 99% of the token market according to market capitalization of classified tokens.
  • ITSA’s Tokenbase currently holds data on over 4000 tokens. Tokenbase is a holistic database for the analysis of tokens and combines our identification and classification data with market and blockchain data from external providers. Third-party data of several partners is already integrated, and API access is also in development.
