More Than Faster Bitcoin
Liquid is a platform for building financial applications on Bitcoin, with capabilities that the base layer does not support.
The Bitcoin base layer optimizes for decentralization and security. That design choice means slower confirmation times (~10 minutes per block), publicly visible transaction amounts, and no native support for assets other than bitcoin. These are deliberate tradeoffs, and they limit what can be built directly on Bitcoin's base layer.
Liquid operates as a layer-2 sidechain. It inherits Bitcoin's monetary properties (fixed supply, permissionless access, cryptographic security) while adding features that serve specific use cases: faster settlement, private transactions, asset issuance, and programmable contracts. The security model differs from the base layer. Instead of proof-of-work mining, Liquid uses a federation of operators (exchanges, financial institutions, and infrastructure providers) that collectively sign blocks. This federation structure enables the faster block times and additional features.
The result is a Bitcoin-native financial layer where you can do far more than send bitcoin faster. Here is what that looks like in practice.
LBTC: Bitcoin on Liquid
Liquid bitcoin (LBTC) is the native asset of the Liquid Network. It is pegged 1:1 to bitcoin on the Bitcoin mainchain: one bitcoin locked on the base layer equals one LBTC on Liquid. The peg is managed by the Liquid Federation through a multisig process, and users can move bitcoin between the two layers through peg-in and peg-out transactions.
How the Peg Works
To move bitcoin onto Liquid, you perform a peg-in: send bitcoin to a federation-controlled address on the Bitcoin mainchain. After 102 confirmations (roughly 17 hours), the equivalent amount of LBTC becomes available on Liquid. This confirmation threshold exists to provide strong finality guarantees before issuing LBTC.
Moving LBTC back to the mainchain (a peg-out) reverses the process. The federation releases the locked bitcoin back to a mainchain address. Peg-outs typically complete faster than peg-ins because the federation can authorize the release without waiting for the same depth of confirmations.
What LBTC Enables
Once your bitcoin exists as LBTC on Liquid, it gains all of Liquid's features:
- Faster transfers: ~1-minute block times instead of ~10 minutes. Two confirmations on Liquid provide settlement finality equivalent to six confirmations on the base layer.
- Private transactions: Every LBTC transfer uses Confidential Transactions by default, hiding both the amount and asset type from outside observers.
- Trading: LBTC is the base trading pair on Liquid. You can swap it for USDT, security tokens, or any other Liquid asset.
- Payments: Merchants and payment processors use LBTC for faster settlement without waiting for multiple Bitcoin mainchain confirmations.
- Inter-exchange transfers: Exchanges that are Liquid Federation members can settle LBTC transfers between each other in minutes instead of hours.
The Blockstream app supports Bitcoin, Lightning, and Liquid in a single interface. You can hold bitcoin, LBTC, and Lightning balances in a single self-custodial wallet and move between layers using built-in Lightning ↔ Liquid and on-chain ↔ Liquid swaps. For hardware security, pairing the Blockstream app with Jade gives you offline signing for both Bitcoin and Liquid transactions from the same device.
USDT on Liquid
Tether's USDT stablecoin runs on multiple blockchains: Ethereum, Tron, Solana, and Liquid, among others. The Liquid implementation offers a distinct set of advantages that has driven real-world adoption.
Why USDT Runs on Liquid
Settlement speed. USDT transfers on Liquid confirm in approximately one minute. On Ethereum, confirmation times vary from minutes to hours depending on network congestion and gas fees. On Tron, settlement is faster than Ethereum but still lacks the privacy features Liquid provides.
Lower fees. Liquid transaction fees are consistently low, typically a few cents or less (roughly 25 satoshis for a confidential transaction after the ELIP 200 fee discount, about $0.03). Ethereum gas fees fluctuate dramatically. During high-congestion periods, a single USDT transfer on Ethereum can cost $10-$50 or more. Liquid fees remain stable regardless of network demand.
Privacy by default. Every USDT transfer on Liquid uses Confidential Transactions, hiding both the transaction amount and the asset type. On Ethereum and Tron, USDT transfers are fully visible on public block explorers. Anyone can see who sent how much to whom. On Liquid, outside observers can verify that a transaction occurred, but they cannot see the amount or determine whether the transfer involved USDT, LBTC, or any other Liquid asset.
Bitcoin-native infrastructure. USDT on Liquid operates within the Bitcoin ecosystem. Users who already hold LBTC can swap directly to USDT without bridging to a different blockchain. Institutions that prefer Bitcoin's security model over Ethereum's can keep their stablecoin operations within a Bitcoin-adjacent system.
| Feature | Liquid | Ethereum | Tron |
|---|---|---|---|
| Settlement | ~1 minute | Variable (minutes to hours) | Fast |
| Fees | A few cents or less | $10-$50+ during congestion | Low |
| Privacy | Confidential Transactions (default) | Fully public | Fully public |
| Ecosystem | Bitcoin-native | Ethereum | Tron |
Real Usage
USDT on Liquid sees active use for:
- Trader settlement between exchanges (avoiding mainchain delays)
- Cross-border payments where fast dollar-denominated transfers matter
- Merchant payments where price stability is needed but Bitcoin privacy is valued
- OTC (over-the-counter) trading desks settling large USDT volumes quickly and privately
Issued Assets
The Liquid Network supports the creation and management of custom digital assets. Asset issuance lets any entity issue an asset on Liquid, and that asset inherits all of Liquid's properties: Confidential Transactions, fast settlement, and the ability to trade against LBTC or other Liquid assets.
How Asset Issuance Works at the Protocol Level
Issuing an asset on Liquid is a special transaction type defined in Elements Core. The issuance transaction consumes a regular UTXO as input and produces outputs for the new asset. Each Issued Asset receives a unique 32-byte asset ID derived deterministically from the issuance input's transaction ID and output index, making the asset ID globally unique and tied to the issuance event.
At issuance time, the creator specifies the initial supply and whether a reissuance token should be created. A reissuance token is itself a distinct Liquid asset (with its own asset ID) that grants its holder the ability to mint additional units of the original asset at any time. If no reissuance token is created during the initial issuance, the supply is permanently and provably fixed, since no future transaction can mint new units without a reissuance token to spend. This gives issuers a binary choice: a verifiably capped supply or a controlled-inflation model where the reissuance token holder retains minting authority.
All Issued Assets are protected by the same Confidential Transaction scheme as LBTC. Asset Surjection Proofs cryptographically verify that each output's asset type matches one of the input asset types, preventing asset type forgery without revealing which specific asset is being transferred. This means outside observers viewing a transaction on Blockstream Explorer cannot distinguish an LBTC transfer from a USDT transfer from a security token transfer.
Types of Issued Assets
| Asset Type | Description | Examples |
|---|---|---|
| Security tokens | Represent ownership in real-world financial instruments. Can enforce transfer restrictions, comply with jurisdictional regulations, and settle trades in minutes instead of T+1 or T+2. | Equity, bonds, fund shares, regulated securities |
| Stablecoins | Tokens pegged to a fiat currency, commodity, or other reference asset. Benefit from Liquid's fast settlement and Confidential Transactions. | USDT (most prominent), fiat-pegged tokens |
| Utility assets | Assets that benefit from Liquid's speed and privacy for non-financial use cases. | Reward points, access credentials, gaming assets |
The Liquid Asset Registry
The Liquid Asset Registry is a public directory where issuers register and verify their assets. When an issuer registers an asset, they provide metadata (name, ticker symbol, precision, domain verification) that wallets and explorers use to display the asset correctly.
Without the registry, Liquid assets appear as raw asset IDs. With it, users can see human-readable names and verify that the asset was issued by the entity it claims to represent. Domain verification links the asset to the issuer's website, providing a trust anchor that wallets display to users.
Blockstream's AMP (Asset Management Platform) provides tools for issuing and managing Liquid assets programmatically. AMP handles the technical details of issuance, distribution, and lifecycle management, making it accessible to organizations that need to tokenize assets without building custom infrastructure.
Liquid Swaps
Liquid supports trustless atomic swaps between any two assets on the network. You can trade LBTC for USDT, swap one security token for another, or exchange any pair of Liquid assets without relying on a centralized intermediary to hold funds during the trade.
How Liquid Swaps Work
An atomic swap on Liquid uses a single transaction that either completes entirely or not at all. Both parties sign a transaction that simultaneously transfers their respective assets. If either party refuses to sign, neither transfer happens. There is no window where one party has sent their asset but not yet received the counterparty's asset.
This is possible because Liquid transactions can contain multiple inputs and outputs from different parties. The swap is encoded into a single transaction that the network processes atomically. At the protocol level, one party constructs a partially signed transaction (PSET) with their inputs and desired outputs, then passes it to the counterparty, who adds their own inputs and outputs and completes the signing. Liquid wallets such as SideSwap handle this construction so users do not build the transaction by hand.
Why This Matters
No counterparty risk. Traditional exchanges require you to deposit funds, trusting the exchange to execute the trade and return your assets. With Liquid swaps, you never lose control of your assets until the moment the swap completes.
No front-running. Because Liquid transactions use Confidential Transactions, the amounts and asset types in a pending swap are hidden. Other participants on the network cannot see the details of your trade and race to exploit them.
Privacy. Completed swaps reveal nothing about the amounts or assets involved to outside observers. Only the two parties in the swap know the terms of the trade.
Cross-Layer Swaps
Bitcoin exists across multiple layers: the base layer (on-chain), the Lightning Network, and the Liquid Network. Each layer serves a different purpose: the base layer provides maximum security and decentralization, Lightning provides instant low-cost payments, and Liquid provides fast settlement with privacy and asset support.
Cross-layer swaps allow you to move bitcoin between these layers based on what you need at any given moment.
Lightning ↔ Liquid
A Lightning ↔ Liquid swap converts a Lightning balance to LBTC on Liquid (or the reverse). This is useful when:
- You have bitcoin on Lightning but need the privacy features of Liquid for a particular transaction.
- You hold LBTC and want to make an instant Lightning payment without waiting for a peg-out to the mainchain and then opening a Lightning channel.
- You want to consolidate small Lightning payments into a larger LBTC balance for trading or long-term holding.
On-Chain ↔ Liquid
On-chain ↔ Liquid swaps move bitcoin between the Bitcoin mainchain and Liquid. While the standard peg-in process requires 102 confirmations, cross-layer swaps can provide faster access to LBTC by using swap providers who already have liquidity on both layers.
The Blockstream app supports both Lightning ↔ Liquid and on-chain ↔ Liquid swaps from a single interface. You select the layer you want to move from, choose the destination layer, and the app handles the swap execution. In practice, your bitcoin is always on the layer where it is most useful, and moving between layers is a straightforward operation rather than a complex multistep process.
Private Transactions
Every transaction on the Liquid Network uses Confidential Transactions by default. Privacy is built into the protocol itself, so users do not need to turn it on.
What Confidential Transactions Hide
Confidential Transactions hide two pieces of information from outside observers:
- Transaction amounts. An observer can see that a transaction occurred between two addresses, but cannot determine how much was transferred.
- Asset types. Liquid supports multiple asset types (LBTC, USDT, security tokens, and others). Confidential Transactions hide which asset was transferred. An observer cannot distinguish an LBTC transfer from a USDT transfer from a security token transfer.
What Remains Visible
Confidential Transactions do not hide everything. The following information remains visible on the Liquid blockchain:
- That a transaction occurred
- The addresses involved (sender and receiver)
- The transaction fee (paid in LBTC)
- The number of inputs and outputs
The sender and receiver of a transaction can still see the full details. Either party can also choose to share a "blinding key" with a third party (such as an auditor or regulator) to reveal the amounts and asset types of specific transactions.
How It Works
Confidential Transactions use a cryptographic technique called Pedersen commitments. Instead of broadcasting the actual amounts, the transaction contains a mathematical commitment that proves the amounts balance (inputs equal outputs plus fee) without revealing what those amounts are. Range proofs accompany each commitment to prove the amounts are positive and within valid bounds, preventing inflation attacks.
This cryptography has been running in production on the Liquid Network since launch. You can verify Liquid transactions on Blockstream Explorer, where the amounts and asset types display as "Confidential" for outside observers.
Faster Settlements
The Liquid Network produces blocks approximately every minute, compared to Bitcoin's average of ten minutes.
What One-Minute Blocks Mean in Practice
Two confirmations on Liquid provide strong settlement finality. Because Liquid uses a federated consensus model (rather than probabilistic proof-of-work), two block confirmations on Liquid give comparable finality guarantees to six confirmations on the Bitcoin mainchain. Two Liquid confirmations take roughly two minutes. Six Bitcoin confirmations take roughly 60 minutes.
Trading settlement. When a trader moves bitcoin between exchanges using the Bitcoin mainchain, they typically wait for three to six confirmations before the receiving exchange credits their account. That is 30-60 minutes of idle time where capital is locked in transit. On Liquid, the same settlement completes in under three minutes.
Payment finality. A merchant accepting bitcoin on-chain might wait for one or more confirmations before considering a payment settled. On Liquid, the merchant has equivalent certainty in minutes instead of the 10-60 minute range on the base layer.
Batch processing. Businesses that process many transactions can batch them on Liquid with faster throughput. Each block can contain the same volume of transactions, but blocks arrive ten times more frequently.
The Tradeoff
Faster block times on Liquid come from its federated consensus model. The Bitcoin base layer's slower blocks are a direct consequence of its decentralized proof-of-work mining and the security guarantees it provides. Liquid complements the base layer rather than replacing it, serving use cases where speed matters more than maximum decentralization.
Securities and Tokenization
The Liquid Network supports the issuance of regulated securities as digital assets. This is one of the areas where Liquid's combination of features (Confidential Transactions, fast settlement, and programmable asset controls) creates a distinct advantage over both traditional financial infrastructure and other blockchain platforms.
Why Liquid for Securities
Confidential Transactions protect trading activity. When securities trade on public blockchains like Ethereum, every trade is visible to the entire network. Competitors, counterparties, and front-runners can all monitor trading activity. On Liquid, Confidential Transactions hide the amounts and asset types of every transaction, preserving the privacy that institutional participants require.
Transfer restrictions. Liquid supports transfer-restricted assets, meaning the issuer can control who is allowed to hold and trade the asset. This is essential for securities compliance: only verified investors in permitted jurisdictions should be able to trade a regulated security. AMP provides the tooling to enforce these restrictions programmatically.
Fast settlement reduces risk. Traditional securities settle on a T+1 or T+2 basis (one or two business days after the trade). During the settlement window, both parties carry counterparty risk. On Liquid, settlement is final in minutes, collapsing the risk window from days to single-digit minutes.
Institutional Trading on Liquid
For institutional traders, Liquid addresses several pain points:
- No front-running. Confidential Transactions mean pending orders and settlement transactions do not leak information to other market participants.
- Faster capital efficiency. Capital locked in settlement is capital that cannot be deployed elsewhere. One-minute blocks free capital faster.
- Reduced counterparty exposure. Atomic swaps on Liquid eliminate the need to trust a centralized clearinghouse during trade settlement.
Treasury Management With LBTC
Organizations that hold bitcoin as a treasury asset can use LBTC for operational transactions while keeping their long-term reserves on the Bitcoin mainchain. LBTC provides faster internal transfers (between departments, subsidiaries, or partners), private transaction amounts (competitors cannot monitor treasury flows), and the ability to quickly swap to USDT during periods of volatility.
The peg between LBTC and bitcoin means there is no exchange-rate risk between the two. One LBTC always equals one bitcoin. Moving treasury bitcoin onto Liquid for operational use and back to the mainchain for cold storage is a matter of executing peg-in and peg-out transactions.
Developer Applications
The Liquid Network is built on Elements, an open-source sidechain platform created by Blockstream. Developers can build on Liquid using familiar Bitcoin tooling, with additional capabilities that the base layer does not offer.
Building With Elements
Elements extends Bitcoin's codebase with Liquid-specific features. Developers who already work with Bitcoin Core find the APIs and data structures familiar. The key additions include:
- Asset issuance: Create, reissue, and destroy assets programmatically.
- Confidential Transactions: All transactions are confidential by default. The APIs support blinding, unblinding, and selective disclosure of transaction details.
- Multisig and timelocks: Bitcoin Script works on Liquid, enabling the same multisig, timelock, and conditional spending patterns available on the base layer.
- Federation API: Interact with the Liquid Federation for peg-in and peg-out operations.
Simplicity Smart Contracts
Simplicity is a smart contract language available on the Liquid Network. Unlike general-purpose smart contract languages (such as Solidity on Ethereum), Simplicity is designed for formal verification. Every Simplicity program can be mathematically proven to behave exactly as specified, with no unexpected edge cases.
Formal verification matters for financial applications where bugs have real monetary consequences. A formally verified smart contract provides stronger guarantees than one that has been audited but cannot be proven correct. Simplicity launched on the Liquid Network mainnet in July 2025, enabling contracts for escrow, complex multisig schemes, and conditional asset transfers.
Simplicity is intentionally limited in scope compared to Turing-complete languages. It handles the financial logic that Liquid's use cases demand (conditional spending, covenant enforcement, complex authorization) without the attack surface that comes with general-purpose computation. The design philosophy: be expressive enough for real financial applications, constrained enough that formal verification remains practical. Developers write contracts in SimplicityHL (the high-level language), compile them to Simplicity's core combinator representation using the simc compiler, and Simplicity's semantics are formalized in the Coq proof assistant, so a contract's behavior can be formally proven to match its specification. Every Simplicity program has a static, pre-computable cost bound, meaning nodes can determine the exact computational resources a program requires before executing it.
What Developers Are Building
- Exchange infrastructure: Liquid-native order books and settlement engines that use atomic swaps instead of centralized matching.
- Custody solutions: Multisig vaults with Liquid's fast settlement for operational funds and Confidential Transactions for privacy.
- Payment systems: LBTC and USDT payment processors that leverage one-minute confirmations and low fees.
- Asset management platforms: Tools for issuing, distributing, and managing security tokens and other Liquid assets.
- Financial primitives: Lending, borrowing, and liquidity provision using Simplicity contracts with formally verified logic.
Hardware Security for Liquid Assets
Liquid assets, like any bitcoin, should be secured with proper self-custody practices. Jade is the only Bitcoin hardware wallet with native Liquid support. It can sign LBTC transactions, manage Liquid assets, and interact with Confidential Transactions directly on the device. Air-gapped QR code signing means the device never needs a USB or Bluetooth connection to your companion app, keeping your signing keys physically isolated from internet-connected devices.
Securing Liquid assets on hardware follows the same principle as securing bitcoin: your keys never leave the device. The Blockstream app connects to Jade as a companion app, displaying transaction details and broadcasting signed transactions to the network while the private keys remain on the hardware wallet.
Frequently Asked Questions
Is LBTC the same as bitcoin?
LBTC is pegged 1:1 to bitcoin on the Bitcoin mainchain. One LBTC always represents one bitcoin locked in the Liquid Federation's 11-of-15 multisig wallet. The total LBTC supply is publicly auditable by checking the federation's peg wallet on the Bitcoin mainchain. However, LBTC carries a different trust model: it depends on the Liquid Federation to honor the peg, while bitcoin on the base layer depends on proof-of-work mining. LBTC is bitcoin moved to a different layer with different tradeoffs, not a separate currency.
Are Liquid transactions really private?
Liquid transactions use Confidential Transactions by default, which hide both transaction amounts and asset types from outside observers using Pedersen commitments and range proofs. The addresses of the sender and receiver remain visible, as does the fact that a transaction occurred. For full anonymity (hiding who transacts with whom), additional techniques would be needed. Confidential Transactions specifically protect the financial details of each transaction. Either party can selectively reveal details to auditors or regulators using blinding keys without exposing data to the public.
How is Liquid different from the Lightning Network?
Lightning is optimized for instant, small payments with negligible fees. Liquid is optimized for larger transactions that need privacy (Confidential Transactions), asset support (USDT, security tokens), and reliable settlement in minutes. Lightning uses payment channels and routing; Liquid uses a federated sidechain with its own blockchain. They serve different use cases, and cross-layer swaps (Lightning ↔ Liquid) allow you to move bitcoin between them.
Who controls the Liquid Network?
The Liquid Federation includes more than 85 member entities (as of April 2026) drawn from exchanges, financial institutions, and Bitcoin infrastructure companies. A subset of these members, the 15 functionary operators, run the hardware that signs blocks and manages the peg. Block production and peg management both use 11-of-15 multisig among the active functionaries. No single member can control the network or access the locked bitcoin unilaterally. Blockstream created Liquid and maintains the open-source Elements Core codebase, but the federation operates the network. The federation member list is public.
Can I use Liquid without trusting Blockstream?
Yes. The Liquid Network is operated by the federation, not by Blockstream alone. Blockstream is one federation member among many. The Elements codebase that powers Liquid is open-source, and anyone can run a Liquid node to verify the blockchain independently. The trust requirement is in the federation collectively, not in any single entity.
What wallets support Liquid?
The Blockstream app supports Liquid natively on mobile, including LBTC, USDT, and other Liquid assets. For hardware security, Jade provides native Liquid signing with air-gapped QR codes. Several third-party wallets and exchanges also support Liquid assets.
