Liquid is a cutting-edge blockchain network designed to deliver enhanced privacy, speed, and functionality for digital asset transactions. Built as a sidechain to Bitcoin, Liquid enables fast, secure, and confidential transfers of Bitcoin and custom-issued assets—making it a preferred choice for exchanges, institutions, and advanced users seeking efficiency and discretion.
At the core of Liquid’s innovation lies Confidential Transactions (CT), a cryptographic breakthrough that ensures transaction privacy by default. Unlike transparent blockchains where every detail is publicly visible, Liquid hides both the amount and type of asset being transferred from all third parties—including federation members and network validators.

This means that when LBTC (Liquid Bitcoin) or USDT-Liquid is sent across the network, only the sender and receiver can view the transaction details. Even nodes validating the transaction cannot see the values involved. However, the underlying cryptography ensures that no new assets are created out of thin air—nodes can still verify that inputs equal outputs without knowing their actual amounts, preserving monetary integrity.
How Confidential Transactions Work: Blinding and Verification
The mechanism behind this privacy is called blinding. Each transaction uses cryptographic "blinding factors" to obscure the amount and asset type. These factors ensure that while the data is hidden, it remains mathematically verifiable. Only the recipient holds the key to decrypt the value they’ve received.
Importantly, the receiver has full control over disclosure. They can choose to share the private blinding key with auditors, regulators, or counterparties who need to verify transaction authenticity. This selective transparency supports compliance without sacrificing default privacy.
For example, an auditor reviewing financial records can be granted access to unblind specific transactions using tools like Blockstream Explorer. By applying the blinding key, the full details—including asset type and amount—become visible only to authorized parties.
Liquid transactions include confidential addresses, which combine a base address with a public blinding key. This structure enables end-to-end encrypted value transfer while maintaining compatibility with existing wallet infrastructure.
Transaction Fees and Network Efficiency
Every Liquid transaction includes a minimal fee—starting at 0.1 satoshi per vByte—to prevent spam and denial-of-service attacks. While fees may increase slightly during periods of high demand, they remain low due to the network’s efficient consensus model.
Due to the inclusion of range proofs in Confidential Transactions, Liquid transactions are slightly larger than standard Bitcoin transactions. Range proofs cryptographically confirm that no output has a negative value (preventing inflation), without revealing the actual amount. These proofs are optimized so that all possible transaction values up to 21 million BTC (in satoshis) appear indistinguishable on-chain.
Since Elements 0.18.1.6, the default range proof size is 52 bits, allowing full confidentiality for all practical transaction sizes. Earlier versions exposed larger transactions by generating bigger proofs, but this limitation has been resolved—ensuring uniform privacy across all transfers.
Issued Assets: Programmable Digital Tokens on Liquid
Beyond private Bitcoin transfers, Liquid empowers users to issue and manage custom digital assets through its Issued Assets feature. These tokens can represent real-world assets such as fiat currencies, equities, commodities, or even NFTs—all secured by Bitcoin-level cryptography.
Each issued asset receives a unique 64-character hexadecimal identifier stored on-chain. Additional human-readable metadata can be registered via the Liquid Asset Registry, enhancing usability across wallets and explorers.
Key metadata fields include:
- NAME: The display name (5–255 characters).
- TICKER: Optional symbol or serial number (3–24 characters).
- DOMAIN: A verifiable domain proving issuer ownership.
- ASSET AMOUNT: Quantity issued, typically in satoshi units.
- TOKEN AMOUNT: Number of reissuance tokens created.
- PRECISION: Decimal places for display (0–8; 8 = BTC-like divisibility).
- PUBKEY: Public key for verifying future registry updates.
- COLLECTION: Optional grouping for NFT sets.
For instance, issuing 100 units of a token with precision 2 will show as “1.00” in registry-aware apps. With precision 8, it mirrors BTC formatting exactly.

Reissuance and Supply Control
Issuers can optionally generate reissuance tokens, granting authority to mint more of an asset later. These tokens support multisig schemes ("m-of-n"), enabling institutional-grade governance over supply changes.
Assets can also be verifiably destroyed, reducing circulating supply—a critical feature for redemption mechanisms or deflationary models.
Real-World Use Cases of Liquid’s Technology
1. Tokenized Fiat Currencies
Financial institutions can back tokens with real fiat deposits held in trust. Each token represents a 1:1 claim on underlying currency. Users deposit funds, receive tokens instantly via Liquid, and redeem them anytime. Auditors can verify reserves match outstanding tokens using unblinding techniques—ensuring transparency without compromising daily privacy.
2. Security Tokens & Asset-Backed Instruments
Liquid supports issuance of regulated financial instruments like bonds, stocks, or derivatives. Combined with platforms like Blockstream AMP, issuers can enforce transfer restrictions, enabling compliance with securities laws while leveraging blockchain efficiency.
3. Cross-Exchange Settlement
Exchanges use Liquid to enable near-instant deposits and withdrawals. Instead of waiting hours for on-chain confirmations, funds settle in under three minutes with just two confirmations—reducing counterparty risk and enabling rapid arbitrage opportunities.
Traders no longer need to pre-fund multiple exchanges. They can hold funds in personal Liquid wallets and deploy capital within minutes wherever opportunities arise—shifting custodial risk from individual platforms to the decentralized federation.
4. Collateralized Cryptocurrency Tokens
While Liquid natively supports only Bitcoin via its peg mechanism, other cryptocurrencies can be represented through collateralized tokens issued by trusted parties. This allows safe trading of altcoin exposure without integrating additional blockchains—simplifying operations for exchanges and traders alike.
Frequently Asked Questions
Q: Can anyone see my transaction amounts on Liquid?
A: No. By default, all transaction amounts and asset types are hidden using Confidential Transactions. Only you, the recipient, and anyone you explicitly authorize with a blinding key can view the details.
Q: How do I prove a transaction occurred to an auditor?
A: You can share the private blinding key or generate an unblinding link that allows third parties to view specific transaction data in explorers like Blockstream Info.
Q: Can I issue my own token on Liquid?
A: Yes. Anyone can create an issued asset with customizable supply, name, ticker, and divisibility—all secured by the Liquid Network’s robust infrastructure.
Q: Are Liquid transactions faster than Bitcoin?
A: Yes. With block times of approximately one minute and final settlement in under three minutes (after two confirmations), Liquid offers significantly faster processing than mainchain Bitcoin.
Q: Is there a limit to how many assets I can issue?
A: There is no technical limit. You can issue as many unique assets as needed, each with its own properties and metadata registered in the global Asset Registry.
Q: What happens if I lose my blinding key?
A: Losing your blinding key means you cannot view transaction amounts in certain wallets or prove ownership to third parties. Always back up keys securely during issuance or receipt.
