What Are the Key Features of Liquid Network?

✨
Confidential Transactions
By default amounts and asset types are hidden, protecting investors sensitive financial data from third parties and front running, while still providing selective audit trail for regulatory compliance.
⚡
Fast Block Confirmation
On average, the time it takes to validate a Bitcoin transfer using the Liquid Network was approximately two minutes. In comparison, validating a Bitcoin transfer typically takes 10 minutes, enabling institutional investors to complete rapid exchange deposits and withdrawals.
💳
Native Asset Issuance
Institutions can use the Liquid Network to issue utility tokens, security tokens, stablecoins (such as USDT and DAI), and non-fungible tokens (NFTs) with all of the same compliance and private features as ERC-20 tokens.
✨
Peg-in/Peg-out Mechanism
Conversion between Bitcoin on the mainchain and Liquid Bitcoin (L-BTC) can be done seamlessly, with a 102-confirmation security lock on each transaction to prevent any chain reorganization attacks.
✨
Federated Consensus Model
Rather than using proof-of-work mining to generate new blocks, functionaries sign blocks through a round-robin system. This enables institutional-level transaction finality, while maintaining the overall integrity of the blockchain.
👥
Asset Management Platform (AMP)
The Liquid Network offers an extensive set of APIs that enables the creation and administration of digital assets through multiple methods of equity and/or debt distribution, and complete control over the asset lifecycle.
🔒
Bitcoin-Based Security Model
The Liquid Network is built using Bitcoin’s UTXO model and codebase, thus preventing any invalid transactions from being confirmed and streamlining both auditing and regulatory requirements.

What Technology Stack and Infrastructure Does Liquid Network Use?

What Are the Best Use Cases for Liquid Network?

Cryptocurrency Exchanges
By allowing customers to hold their own assets on the Liquid Network, we can offer customers faster deposit and withdrawal options and reduce the risk of custodial concentration in one institution, enabling customers to transfer assets rapidly between exchanges without the delay of confirming transactions on the Bitcoin main chain.
Institutional Market Makers
Through the use of Confidential Transactions (CT), we enable institutional traders to execute large volume Bitcoin transactions and trade complex financial derivatives, providing them with competitive pricing without revealing sensitive order flow information.
Digital Securities Issuers
We can issue and administer regulated security tokens with selective audibility, white listing capabilities and full life cycle management while protecting the identity of investors.
Stablecoin Issuers
We can also issue stable coins such as USDT with confidential transactions and fast settlement; enabling our clients to engage in continuous trading (24/7) versus the traditional banking hours of 9-5 Monday through Friday.
Financial Asset Traders
Our users have access to decentralized peer-to-peer trading of tokenized securities and financial instruments, which are accessible via a permissionless distributed ledger system that is operational 24 hours a day, 365 days a year.
NOT FORRetail Bitcoin Users
Liquid Network is limited in its applicability, as it was developed with institutional high volume traders in mind and not retail micro payments or general daily transactions.
NOT FORDecentralized Finance (DeFi) Developers
The federated model of the Liquid Network and the enterprise focused design of the Liquid Network are opposite to the governance models typically found within Decentralized Finance (DeFi) ecosystems.
NOT FORPrivacy-Focused Individuals
While Confidential Transactions do provide the user with the ability to maintain their anonymity, the federated trust model of the Liquid Network still allows functionaries to view metadata related to each transaction and therefore the users will have to be willing to trust the functionaries who are part of the federation.

How Does Liquid Network Compare to Competitors?

vs Bitcoin Mainchain

The Liquid Network is a sidechain/Layer 2 to the Bitcoin mainchain and has significantly reduced costs and increased speeds ($0.01-$0.50 vs $10-$40+). The security of the Liquid Network is provided by a federated peg mechanism and the cost savings and speed increase are offered without sacrificing the security of the Bitcoin mainchain. The primary advantage of the Bitcoin mainchain is its level of decentralization and larger settlements.

Use Liquid for everyday bitcoin transactions and capital market applications. For ultimate settlement and maximum decentralization, use the bitcoin mainchain.

vs Lightning Network

The reason for instant, zero cost, micropayments and regular commerce using lightning is because liquid supports higher volume transactions, asset creation and institutional type projects. Both are complementary to one another in the bitcoin ecosystem as well as providing trustless swap capabilities between both platforms.

For institutional or capital markets use liquid. For consumer payments and micro-payments use lightning.

vs Ethereum Layer 2s (Arbitrum, Optimism)

Ethereum L2s allow for broader smart contract usage with more developer focus, however, Liquid has the advantage of supporting the entire bitcoin security model and can natively issue assets. Additionally, Liquid’s Simplicity smart contract language also has the formal verification benefits over Ethereum L2s which have a much greater DeFi ecosystem.

Use Liquid when developing bitcoin native applications and capital markets, use Ethereum L2s when developing DeFi applications and more broad applications.

vs Stacks (Layer 1 on Bitcoin)

Although both Liquid and Stacks build on top of bitcoin, they differ in their design approach. Liquid is a side chain that allows for faster settlements than bitcoin and has existing merchant infrastructure to support USDT, whereas Stacks is utilizing proof of transfer and attempting to create smart contract parity with ethereum. Liquid is more developed and has a total value locked (TVL) of $3.27B.

When you want to make a payment or create a stablecoin, use Liquid. If you want to create a bitcoin native smart contract or DeFi application, use Stacks.

What are the strengths and limitations of Liquid Network?

Pros

  • Dramatic reductions in transaction fees -- .000001 BTC per byte (.1 satoshis) compared to $10-$40+ on the bitcoin mainchain. This represents a 99% reduction in cost for all but the largest transfers.
  • Faster confirmation times -- 2 minute block time versus 10+ minute confirmation times on the bitcoin mainchain. This enables users to make time sensitive transactions.
  • Utilizes bitcoin security model -- shares the same open-source code base as bitcoin and utilizes the same proven cryptography to secure the network.
  • Natively issues assets -- supports stable coins (USDT), tokenized securities, and bonds all without requiring additional token standards to be created.
  • Provides enhanced privacy -- Confidential transactions are built into Liquid to provide privacy for the user which bitcoin mainchain does not have.
  • Infrastructure ready to be institutionalized -- merchant payment solutions, integration with exchanges, and Business API’s.
  • Capability to perform formal verification – the ability to mathematically prove a contract is correct prior to executing it using Simplicity, the smart-contract language.
  • Ecosystem already established – first sidechain of Bitcoin (2014), $3.27 billion in total value locked, widely adopted by exchanges and platforms.

Cons

  • Federated security model – uses Multisig Federation as opposed to full decentralization; introduces trust assumptions in contrast to the mainchain of Bitcoin.
  • Lower network effect than Bitcoin -- smaller user base and less liquidity than mainchain, limits adoption.
  • Complexity of sidechain peg-in -- requires an understanding of L-BTC conversion and on-chain fees for mainchain peg-ins.
  • Smaller smart-contract ecosystem – smaller developer community than that of Layer 2’s of Ethereum, fewer smart-contracts have been deployed.
  • Uncertainty surrounding regulations -- asset issuance and stablecoin support may encounter evolving regulatory pressures.
  • Delays in bridge/peg-out – peg-outs from Bitcoin mainchain are subject to mainchain confirmation time and fees.
  • Merchant adoption of Liquid is less prevalent -- fewer merchants accept Liquid directly in comparison to the growing number of merchants who accept the Lightning Network.

Who Is Liquid Network Best For?

Best For

  • Cryptocurrency exchanges and institutional traders — Enables rapid and private transfer of assets between platforms at minimal cost -- enables rapid and private arbitrage and settlements without mainchain congestion.
  • Stablecoin payment processors and merchants — Support for USDT and stablecoins with low fees and rapid confirmations -- provides a functional payment infrastructure for merchants and exchanges.
  • Financial institutions issuing tokenized securities or bonds — Designed to serve capital market assets with privacy features, formal verification capabilities, and enterprise grade infrastructure.
  • Bitcoin holders seeking cheaper transactions — Converts BTC to L-BTC for a 0.1 percent fee, and then enjoys 99 percent lower transaction costs when making transfers or swapping assets.
  • Developers building Bitcoin-native applications — Enables developers to build secure, formally verified smart contracts using Simplicity -- builds upon the proven security model of Bitcoin, while eliminating the complexity of Ethereum.

Not Suitable For

  • Decentralization maximalists — A federated security model may require a user to have faith in Liquid Federation. For complete decentralization, a user could consider using the Bitcoin main chain or a fully decentralized side chain such as the Bitcoin Testnet.
  • Everyday retail micropayment users — The Lightning Network may be more appropriate for sub-cent transactions and consumer payments. Larger transactions and institutional usage will be supported by Liquid.
  • DeFi developers and users — The Liquid ecosystem is limited compared to the number of developers supporting an Ethereum Layer 2. If a user wants a fully functioning DeFi infrastructure, they may want to consider using Arbitrum or Optimism.
  • Extreme privacy-focused users — While Liquid does provide a degree of enhanced privacy, users requiring total anonymity should consider using a privacy coin. Liquid is still based on a traditional Bitcoin compatible transaction model.

What Are Common Questions About Liquid Network?

The Liquid Network is a Bitcoin side chain and layer 2 solution designed to support fast transactions (2 minute finality), confidential asset transfer, and secure digital asset creation, such as stablecoins and security tokens. The Liquid Network utilizes a federated peg system to achieve 1:1 interoperability with the Bitcoin Main Chain.

Peg-in: User sends BTC to a Liquid generated BTC address (102 confirmations are required), user receives an equivalent amount of L-BTC. Peg-out: User burns L-BTC and requests a withdrawal from one of the federation members (processing time can vary between 20-60 minutes). Liquid exchanges enable both of these processes.

Liquid provides fast confidential transactional capabilities with two minute settlements via side chain pegs. Lightning provides instant micro-payment capability utilizing payment channels. Both are UTXO-based L2 solutions for Bitcoin but each is used to process a different size of transactions.

Liquid uses a federated consensus model utilizing 60+ trusted functionaries (exchanges, institutions) to sign blocks. Full nodes can be run by anyone to verify the 1:1 backing and the transactions performed on the network; however, at least 2/3 + 1 of the functionaries must agree for the network to operate.

Liquid supports the issuance of a wide variety of assets including tokenized fiat, securities, stablecoins, cryptocurrencies, etc. All of these assets are created with confidential transactions and compliance features. Assets also support human readable metadata and utilize multisig security.

Security of liquid is based on the same chain as bitcoin through an equal amount of 1:1 pegged l-btc stored in a multi-sig wallet. All transactions are secure by default and have no counterparty risk with atomic swaps and do not rehypothecate any collateral. All nodes provide full ability to independently verify all transactions.

Blockstream is the company that has provided the necessary technology for the liquid network (elements platform). The liquid federation (over 60 members including exchanges, banks etc.) makes decisions about how to operate the network.

Less decentralized than bitcoin because it uses a federated model. If one of the federation members goes down when doing a "peg out" it will take 20-60 minutes. Also if 1/3 or more of the federation members go down the entire network will halt.

Is Liquid Network Worth It?

Liquid Network is currently the most developed of all the Bitcoin layer-2 sidechains and is best suited for institutional and developer focused, confidential, fast-settling transactions and tokenization of assets. It also allows the federation to rapidly deploy new features and for use in capital markets. It is best suited for financial institutions that require to issue tokens representing their assets using the security of the Bitcoin blockchain.

Recommended For

  • Institutional and retail crypto exchanges that require fast settlement of cross border btc transactions.
  • Financial institutions that require to issue tokenized securities and/or stablecoins on the bitcoin blockchain.
  • Traders that need to make large btc transactions confidentially.
  • DeFi platforms that want to expand into the bitcoin ecosystem.
  • Capital market firms that want to tokenize physical assets and represent them as digital tokens on the bitcoin blockchain.

!
Use With Caution

  • Projects that require full permissionless decentralization.
  • Retail users that require a simple self-custody experience.
  • Applications that require instantaneous micro payments (this is better served by lightning).
  • Jurisdictions that are uncomfortable with the concept of a federated custodian model.

Not Recommended For

  • Permissionless DeFi protocols that require miner extractable value.
  • Retail payment application that requires a very high level of decentralization.
  • Projects that prioritize absolute censorship resistance above all else even at the expense of speed.

What do expert reviews and research say about Liquid Network?

Key Findings

Liquid Network has been operating since 2018 as a Bitcoin sidechain, with over 60 federation members. Liquid focuses on Confidential Transactions (CT), which allows for near-instant settlement, and asset tokenization, specifically designed for use in Capital Markets. The Federated model that Liquid uses provides for quick upgrades, however, the trade-off is some level of centralization compared to the Bitcoin Main Chain and/or the Lightning Network.

Data Quality

Good - comprehensive technical documentation and ecosystem analysis available. Official website sparse on user-facing details. No pricing/revenue data (open network). User reviews limited as infrastructure product.

Risk Factors

!
Due to the Federated Consensus model, Liquid faces a similar Single Point of Coordinated Failure risk as other Federated models.
!
Liquid’s Peg-Out functionality is dependent on its federation members/ institutions, if one of these entities goes down, then the peg-out fails.
!
Compared to both the Bitcoin Main Chain and the Lightning Network, Liquid has lower decentralization.
!
Although there are many institutional players involved with Liquid, it appears that the primary focus is on Institutional adoption via exchanges rather than Retail or Consumer adoption.

What Are the Best Alternatives to Liquid Network?

  • •
    Lightning Network: The Lightning Network provides an immediate solution for micro-payments at a cost of 2-10 cents per transaction with Payment Channels. It is a layer 2 solution that is more decentralized than Liquid, does not provide Confidentiality, and does not allow for Asset Issuance. It is best suited for High-Frequency Small Transaction Payments. (lightning.network)
  • •
    Rootstock (RSK): RootStock is a Bitcoin side chain that utilizes Smart Contracts and DeFi capabilities. It is more decentralized than Liquid due to its Merged-Mined PoW architecture and provides full Smart Contract support. This makes it an ideal platform for Developers looking to build Ethereum compatible DApps on top of Bitcoin Security. (rootstock.io)
  • •
    Stacks: Stacks is a layer 2 solution for Bitcoin utilizing Smart Contracts through a consensus method called Proof-of-Transfer. It is more Permissionless than Liquid and provides Native DeFi and NFT capabilities. In contrast to Liquid, Stacks settlement is reliant on Bitcoin Miners. As such, this makes it an ideal platform for permissionless Bitcoin-Native Applications. (stacks.co)
  • •
    tBTC / Threshold Network: Threshold is a Decentralized Bitcoin Peg to Ethereum for DeFi. Unlike Liquid, it avoids Federated Custody allowing for Ethereum DeFi Access for Bitcoin Holders. However, it requires a more complex Peg Mechanism. As such, this makes it an ideal platform for Bitcoin Holders who want to gain exposure to Ethereum DeFi Yield. (threshold.network)
  • •
    Ark: Ark Protocol operates as a Layer 2 Bitcoin payment protocol utilizing Virtual Payment Channels. This creates a faster and more private way to send money than the current state of Lightning Network, while also creating a much simpler user experience. At this early stage, Ark Protocol is more comparable to Liquid than to Lightning Network in terms of speed and privacy. Thus, it is ideal for Mobile Bitcoin Payments that improve upon Privacy and Scalability. (ark-protocol.org)
