What is Pocketbook?

Pocketbook is a blockchain-based platform for creating, distributing, and verifying digital certificates. Built on Polygon, it combines the security and permanence of blockchain technology with the accessibility of modern web applications.

Platform Architecture

Pocketbook is built on blockchain technology, allowing you to create verifiable, tamper-proof digital certificates.

Key Components

• Smart Contracts: On-chain certificate storage and verification on Polygon blockchain
• IPFS: Decentralized storage for certificate metadata and images
• API: RESTful API for certificate management and automation
• Dashboard: Web interface for creating and managing certificates
• Smart Account Abstraction: Gasless transactions for recipients using ERC-4337
• Lazy Minting: Voucher system for efficient batch operations

How It Works

1. Create: Design your certificate with metadata, images, and attributes
2. Mint: Issue certificates as NFTs on the Polygon blockchain
3. Distribute: Share certificates with recipients via vouchers or direct minting
4. Verify: Anyone can verify certificate authenticity on-chain

Core Concepts

Certificates

Digital certificates in Pocketbook are ERC-721 NFTs that represent achievements, credentials, warranties, or any verifiable claim. Each certificate contains:

• Name: The certificate title
• Description: Detailed information about the certificate
• Image: Visual representation (stored on IPFS)
• Metadata: Structured attributes (course details, warranty terms, etc.)
• Owner: Wallet address of the certificate holder

Vouchers

Vouchers enable "lazy minting" - certificates are created off-chain and only minted when claimed. This:

• Reduces upfront gas costs
• Enables bulk certificate creation
• Gives recipients control over when to mint
• Allows gasless claiming via smart accounts

Smart Accounts

Pocketbook uses ERC-4337 account abstraction to provide:

• Gasless transactions: Recipients don't need ETH to claim
• Better UX: Email-based recovery and authentication
• Security: No need for private key management

Blockchain & Network

• Chain: Polygon (Layer 2)
• Standard: ERC-721 (NFT)
• Gas Fees: Covered by Pocketbook for recipients
• Finality: ~2 seconds transaction confirmation
• Explorer: Polygonscan
