Have you ever sent crypto to the wrong address and watched your funds disappear forever? Or struggled to identify or remember which deposit address goes with which exchange across different blockchains? The fragmented nature of web3 addressing has been a persistent hurdle to mainstream adoption—until Payment ID provided a solution. By offering user-friendly, standardized identifiers, Payment ID simplifies the process, reducing errors and making web3 transactions more accessible for everyone.

What is Payment ID? 

Payment ID is a unified, human-readable identifier system designed to simplify the complexities of web3 addressing including:

• Intuitive Identifiers: Use straightforward names like alice@binance instead of memorizing complex addresses

• Cross-Chain Compatibility: A single Payment ID resolves to the correct address on any supported blockchain and the system automatically selects the appropriate address based on the network being used

• Error Prevention: Transactions only proceed when addresses are correctly resolved

• Centralized Management: Users can manage all exchange and wallet addresses through one simple interface

With Payment ID, users only need to remember one customizable string that resolves to the correct wallet address on any supported blockchain or exchange, dramatically streamlining the crypto transaction process.

Upgrade from Web2 to Web3 with Payment ID for Email 

What's truly revolutionary about Payment ID is its accessibility for everyday internet users. With Payment ID, Web2 email users don't need to create any blockchain addresses whatsoever to use the system—the entire process works with just your regular email. You can register a Payment ID using your existing email address, eliminating the need to create, manage, or back up cryptocurrency wallets. Through a simple interface, you can easily set address mappings that determine which blockchain addresses your Payment ID resolves to, enabling you to start accepting crypto payments immediately without any technical know-how.

This approach removes the intimidating first steps that typically deter mainstream users from entering the crypto space. And here's what makes it even more accessible: it's completely free. All transactions on the Gravity chain are sponsored, thereby eliminating financial barriers to entry for newcomers.

The Perfect Foundation for Payment ID

With numerous blockchain platforms available, Payment ID's choice of Gravity Chain as its deployment foundation is both strategic and forward-thinking. Payment ID leverages Gravity's innovative technical architecture to enable a better user experience compared with other chains.

Technical Innovations Powering Payment ID

Parallel EVM Execution (Grevm)

Unlike traditional blockchains that process transactions sequentially, Gravity employs Grevm (Gravity EVM), a revolutionary parallel execution system:

• Concurrent Transaction Processing: Rather than executing transactions one at a time, Grevm can identify and process independent transactions simultaneously, dramatically increasing throughput.

• Benchmark-Breaking Performance: Grevm achieves an impressive 26.50 gigagas per second for conflict-free transactions—4.13× faster than sequential execution. With real-world I/O latency factored in, it reaches 6.80 gigagas/s, which is 50.84× faster than traditional methods.

• Intelligent Transaction Scheduling: The system uses data dependency hints from transaction simulations to optimize parallel execution, minimizing conflicts and reducing the need for re-executions.

This parallel architecture is crucial for Payment ID's vision of mass adoption, as it can easily handle both the high volume of transactions and the computational gas requirements needed for ZKPs verification.

Sub-Second Finality

Gravity's architecture delivers near-instantaneous transaction finality which is a game-changer for Payment ID:

• AptosBFT Consensus: Gravity uses AptosBFT, which optimally reduces consensus latency to just 3 network communication hops.

• Pipeline Architecture: The 5-stage pipelined blockchain architecture interleaves different processing stages, allowing parallel execution of multiple blocks simultaneously.

• Time-to-Finality Under 1 Second: Transactions reach finality in under a second, providing an experience comparable to centralized systems.

For Payment ID users, this means address mapping updates appear almost instantly, creating a seamless experience where changes to a user's payment destinations take effect immediately—even when accounting for the on-chain processing time required for email ZKP verification, the overall creation latency remains remarkably low.

Negligible Transaction Costs

Gravity Chain’s native token (G token) is priced extremely low, ensuring that transaction costs remain minimal:

• Free User Operations: Payment ID can sponsor all user operations on Gravity Chain, effectively eliminating financial barriers to entry.

• Address Mapping Updates: Users can update their address mappings without worrying about gas fees.

• No Hidden Fees: The entire experience remains free for users, encouraging widespread adoption.

Future-Proof Scalability

Perhaps most importantly, Gravity offers Payment ID room to grow:

• 1 Gigagas Block Limit: Provides ample computation space for validating complex zero-knowledge proofs, ensuring Payment ID can scale its privacy features.

• Omnichain Settlement: Gravity's design as an omnichain settlement layer perfectly aligns with Payment ID's cross-chain addressing needs.

• Growing Ecosystem: As part of the Galaxy Ecosystem, Gravity is expected to process over 60 million transactions monthly, creating a vibrant network effect that benefits all applications built on it.

Looking Ahead: A Thriving Ecosystem of High-Performance dApps 

Gravity Chain’s architecture isn’t just a perfect fit for Payment ID—it’s built to support a whole ecosystem of decentralized applications with similar needs for speed, scalability, and cross-chain functionality. As developers increasingly seek platforms that can handle complex computation, low-cost operations, and seamless user experiences, Gravity is poised to become a hub for the next wave of web3 innovation. From payments and identity to gaming and DeFi, expect more high-performance dApps to join Gravity’s growing network—each one benefiting from the same robust infrastructure that powers Payment ID.
