Technology Behind Lightspark

Lightning Network Integration

Lightspark leverages the Lightning Network, a second-layer solution built on top of the Bitcoin blockchain, to facilitate fast and low-cost transactions. The Lightning Network operates by creating off-chain payment channels between users, allowing them to conduct multiple transactions without recording each one on the blockchain. This significantly reduces congestion and transaction fees on the main Bitcoin network.

Payment Channels

When two parties open a payment channel, they lock a certain amount of Bitcoin into a multi-signature address. This address requires both parties’ signatures to release the funds. Transactions between the parties are then conducted off-chain, with each transaction updating the balance of the locked funds. Only when the channel is closed are the final balances recorded on the blockchain. This method ensures that transactions are both fast and cost-effective.

SDKs and APIs

Lightspark enhances the Lightning Network process by providing a suite of SDKs and APIs that allow businesses and developers to integrate Lightning Network capabilities into their applications easily. These tools simplify the process of opening and managing payment channels, making it accessible even to those with limited technical expertise. The SDKs and APIs are designed to be user-friendly, even for those with limited technical expertise.

How Lightspark Extend Works

1.Pre-payment Verification

• Compliance Checks: Prior to the transaction being authorized, Extend enables both the sending and receiving financial partners to conduct all required compliance, BSA/AML, and OFAC checks on the relevant customers before any funds transfer can be initiated.
• UMA Setup: Both the sender and receiver can be enabled with UMA, either created on their behalf by their virtual asset service provider (VASP) or created using the Extend flow, to send and receive funds via Lightspark Extend.

2.Payment Initiation

• Payment Request: The sender enters the receiver’s Universal Money Address (UMA) into the sending virtual asset service provider’s app to initiate a payment. The virtual asset service provider then sends an UMA request to the receiving virtual asset service provider — in this case, Lightspark Extend.
• Transaction Data Exchange: The UMA standard contains provisions to exchange information about the transaction such as amount, FX rate, and required compliance data like Travel Rule.
• Invoice Issuance: As part of the UMA flow, Lightspark Extend provides the sending VASP with a Lightning invoice (denominated in bitcoin) that they can use to fulfill the payment.

3.Digital Asset Exchange

• Asset Holding Setup: Lightspark Extend integrates with relevant partners to hold Bitcoin and fiat omnibus accounts at a licensed Digital Assets Exchange. The Bitcoin account maintains a float balance to support timely exchange of bitcoin.
• Asset Liquidation: Upon receiving the Lightning payment, the Digital Asset Exchange is instructed to liquidate the digital assets from the Bitcoin account. These liquidated assets are deposited in the fiat account.
• Bitcoin Transfer: Bitcoin is withdrawn in batches from the Lightning Node to the Digital Asset Exchange to manage float balance.

4.Recipient Payout in Fiat Instantly

• Fiat Payout: After liquidating digital assets, Lightspark Extend immediately initiates an instant payout from the refunded partner bank omnibus account.
• End User Receipt: End users receive local fiat currency of their choice in their denominated bank account.

Universal Money Address (UMA)

The Universal Money Address (UMA) is an open-source standard Lightspark uses to enable human-readable addressing for payments. It leverages the Bitcoin Lightning Network to enable fast, low-cost, and efficient payments across different platforms and currencies. UMA helps reduce errors and enhances the overall user experience by providing a straightforward way to manage payment addresses.

Key Features of Universal Money Address (UMA)

• Human-Readable Addresses: UMAs are unique, easy-to-remember addresses similar to email addresses, making them simple to share and use.
• Interoperability: UMA works with any UMA-enabled wallet, exchange, or bank, allowing seamless transactions across different platforms.
• Real-Time Payments: UMA enables near-instant settlement of transactions, providing a reliable and efficient payment experience.
• Global Reach: Supports cross-border payments, allowing users to send and receive money in their preferred currency, regardless of location.
• Open Source: Any wallet, exchange, or bank can integrate UMA, fostering innovation and new payment solutions.
• Always On: Transactions can be conducted 24/7, ensuring continuous availability.
