About
What Is Loopring [LRC]?
LRC is the Ethereum-based cryptocurrency token of Loopring, an open protocol designed for the building of decentralized crypto exchanges.
In 2020, the average daily trading volume of the entire cryptocurrency market fluctuated in the approximate range of $50-$200 million. Most of that trading is conducted on centralized cryptocurrency exchanges — online platforms operated by private companies that store users’ funds and facilitate the matching of buy and sell orders.
Such platforms have a number of downsides common to all of them, so a new type of exchange — decentralized— has emerged to try to alleviate these disadvantages. However, fully decentralized exchanges are not without their own flaws.
Loopring’s purported goal is to combine centralized order matching with decentralized on-blockchain order settlement into a hybridized product that will take the best aspects of both centralized and decentralized exchanges.
LRC tokens became available to the public during an initial coin offering (ICO) in August 2017, while the Loopring protocol was first deployed on Ethereum mainnet in December 2019.
Who Are the Founders of Loopring?
The founder and current CEO of Loopring Foundation, which manages the development of Loopring protocol, is Daniel Wang, a software engineer and entrepreneur based in Shanghai, China.
Wang has a bachelor’s degree in computer science from the University of Science and Technology of China, as well as a master’s degree in the same field from Arizona State University.
Prior to starting work on Loopring, Wang has held multiple managerial and executive positions in major tech companies: he was a lead software engineer at the medical device manufacturer Boston Scientific, the senior director of engineering, search, recommendation and ads system at the Chinese e-commerce giant JD.com, as well as a tech lead and senior software engineer at Google.
Wang has also co-founded several companies: Yunrang (Beijing) Information Technology Ltd. and the cryptocurrency services firm Coinport Technology Ltd.
What Makes Loopring Unique?
The main idea behind Loopring is to combine elements of centralized and decentralized cryptocurrency exchanges to create a protocol that will enjoy their unique advantages and eliminate inefficiencies.
Centralized exchanges are currently the main mode of operation for crypto trading services. While highly popular and convenient, using a centralized exchange carries a number of risks, the chief of which is their custodial nature. Because these exchanges hold users’ funds for them between the points of depositing and withdrawing, those funds come under the risk of being partially or fully lost due to potential hacker attacks, malicious actors inside the exchange or regulatory intervention.
Another major problem for centralized exchanges is the lack of transparency: the fact that trades are not settled on the blockchain, but rather stored in the exchange’s internal records makes possible price manipulation by the exchange and allows it to use user funds for unauthorized purposes while in custody.
In order to eliminate these problems, a new type of trading service has emerged in recent years: a decentralized crypto exchange (DEX). Instead of holding user funds in custody and processing trades internally, it helps buy and sell orders connect directly with each other and settle trades on a public blockchain.
While removing the custodial and transparency risks, DEXs introduce disadvantages of their own: mainly, lower efficiency (when compared to centralized alternatives) associated with the limited capabilities of the underlying blockchains and fragmented liquidity.
Loopring protocol seeks to keep the advantages of decentralized exchanges while reducing or eliminating their inefficiencies via innovative hybrid solutions. Through managing orders in a centralized manner but settling the trades on-blockchain, and combining up to 16 orders into circular trades instead of allowing strictly one vs. one trading pairs, Loopring expects to increase the efficiency of order execution, as well as enhance the liquidity of DEXs.
How Many Loopring [LRC] Coins Are There in Circulation?
The issuance of LRC tokens is governed by the smart contracts that comprise the Loopring Protocol.
The primary way of earning LRC is via so-called ring mining: in order to improve the liquidity of the Loopring network, the orders in it are not matched strictly as pairs of two cryptocurrencies. Instead, the protocol can mix and match up to 16 orders for different cryptocurrencies in a circular trade, called an order ring.
Nodes on the Loopring network are rewarded in LRC tokens for combining individual orders into order rings, maintaining public order books and trade history, and in some cases broadcasting orders to other relays.
How Is the Loopring Network Secured?
Loopring is operable on Ethereum and Neo blockchains with plans to add support for the Qtum blockchain. Each of these networks has its own token: LRC and LRN for Ethereum and Neo respectively; when launched, the Qtum network token will be called LRQ.
These tokens are secured by the hash functions of their underlying blockchain platforms: LRC by Ethereum’s Ethash, LRN by Neo’s SHA256 and RIPEMD160 and LRQ by Qtum’s proof-of-stake PoSv3 algorithm.

What blockchain does Loopring use? Is it its own blockchain or built on top of another?
Loopring operates as a Layer 2 (L2) scaling solution built on top of Ethereum (ETH). It does not have its own independent blockchain but instead leverages Ethereum's security and decentralization while providing faster and cheaper transactions through its zkRollup technology.
Key Details:
- Layer 2 on Ethereum: Loopring is an optimistic rollup (originally) and later transitioned to zkRollup (a type of zero-knowledge rollup) to enhance scalability and security.
- ZK-Rollup Technology: Loopring uses zk-SNARKs (zero-knowledge proofs) to batch multiple transactions into a single proof, which is then submitted to Ethereum. This reduces gas costs and increases throughput.
- Ethereum as the Base Layer: All funds and smart contracts on Loopring are ultimately secured by Ethereum, meaning users can withdraw assets back to the mainnet if needed.
- Loopring’s Own Protocol: While it relies on Ethereum for security, Loopring has its own decentralized exchange (DEX) protocol and payment system, which operate on top of Ethereum.
Why Not Its Own Blockchain?
- Security: By using Ethereum as the base layer, Loopring inherits Ethereum’s robust security model.
- Interoperability: Being an L2 solution allows seamless interaction with other Ethereum-based DeFi protocols.
- Efficiency: Building on Ethereum avoids the need to bootstrap a new blockchain from scratch.
Loopring’s Future:
Loopring has also explored cross-chain solutions, such as integrating with other blockchains (e.g., Arbitrum, Polygon), but its core infrastructure remains Ethereum-based.

How much data can I store on the Loopring blockchain? Does it support on-chain data storage?
The Loopring blockchain (specifically Loopring Layer 2) is primarily designed for high-throughput, low-cost trading and payments rather than general-purpose data storage. Here’s what you need to know about data storage on Loopring:
1. On-Chain Data Storage on Loopring
- Limited Storage: Loopring L2 (built on Ethereum) inherits Ethereum’s storage limitations. Storing large amounts of data directly on-chain is expensive and inefficient due to high gas costs.
- Smart Contract Storage: You can store small amounts of data (e.g., trade orders, user balances) in smart contracts, but this is not scalable for large datasets.
- IPFS & Off-Chain Storage: For larger datasets, Loopring typically relies on off-chain storage solutions (like IPFS, Arweave, or centralized databases) and only stores hashes or references on-chain for verification.
2. Data Storage Alternatives
- IPFS (InterPlanetary File System): Store files off-chain and pin their CID (Content Identifier) on Loopring for decentralized access.
- Arweave: For permanent, pay-once storage with on-chain references.
- Centralized Storage (AWS, Google Cloud): If decentralization isn’t critical, you can store data off-chain and reference it via smart contracts.
3. Loopring’s Focus
Loopring is optimized for trading, payments, and DeFi, not general data storage. If you need large-scale on-chain data storage, consider:
- Filecoin (for decentralized storage)
- Arweave (for permanent storage)
- Ethereum L2s like Arbitrum or Optimism (with better storage options)
Conclusion
Loopring supports small on-chain data storage (via smart contracts) but is not ideal for large datasets. For scalable storage, use off-chain solutions (IPFS, Arweave) with on-chain references.
