FAQs
What is Paycoin and how does it work?
Paycoin (pci) is a blockchain-based virtual asset payment service developed by Danal, a South Korean payment giant. It allows users to make simple and fast payments at online and offline merchants. Users download the Paycoin app, purchase or convert cryptocurrency into pci, and then use it for payments via QR codes or in-app methods at over 130,000 partnered merchants. This e-commerce solution integrates blockchain into daily transactions, aiming for widespread cryptocurrency adoption.
What problem does Paycoin solve?
Paycoin addresses critical inefficiencies within traditional payment systems, specifically high transaction fees and slow settlement periods. By integrating blockchain technology, Paycoin streamlines payment processes, significantly reducing unnecessary verification costs and minimizing the financial burden for service providers. This innovative approach offers an infrastructure-free payment solution, making digital asset transactions more accessible and efficient for both users and merchants, particularly in e-commerce and retail environments.
What are the main use cases for pci token?
The primary use case for the pci token is facilitating real-world payments at a vast network of participating online and offline merchants, from coffee shops to convenience stores. Users utilize the Paycoin app to charge or convert other virtual assets into pci for instant transactions. Beyond payments, Paycoin plans to introduce advanced services such as DEX-linked Crypto Swap and staking opportunities, further expanding the utility of the cryptocurrency within its growing blockchain ecosystem and rewarding users for their payment history.
How does PayProtocol ensure transaction privacy for merchants and customers?
PayProtocol leverages Hyperledger Fabric's private data collections feature, which encrypts transaction details so only involved parties (customer, merchant, regulator) can access specific data fields. Additionally, validator nodes operate under strict KYC protocols, limiting network participation to vetted entities. For public transactions like PCI↔KRW conversions during card usage, zero-knowledge proofs validate balances without exposing wallet addresses.
What advantages does the Paycoin Mastercard offer over traditional crypto cards?
Unlike conventional crypto cards that incur 1-3% foreign exchange fees, Paycoin Mastercard uses atomic swaps via Uniswap to convert PCI→USDC→24Tokens in real-time with zero conversion fees. Its integration with Web3 identity (Account NFTs) eliminates password requirements while maintaining banking-level KYC. The card's Swiss banking partnership ensures regulatory compliance across 180+ countries, and its $1,000 CHF monthly limit avoids typical debit card restrictions.
How does PayProtocol's tokenomics model prevent inflation?
PCI emissions are algorithmically tethered to network transaction volume; rewards decrease when payment activity drops, creating deflationary pressure during low usage. The PAY token employs a three-pronged deflationary mechanism: 1) 5% of transaction fees are burned; 2) staking locks the circulating supply (45% of PAY is staked for governance); 3) merchant settlement fees fund buybacks. This dual-token structure isolates governance value (PAY) from transactional velocity (PCI).
Can developers build on PayProtocol's infrastructure?
Yes, PayProtocol offers modular SDKs for JavaScript, Python, and Java supporting: 1) e-commerce plugin integration; 2) custom POS interface development; 3) mobile wallet creation. The testnet replicates HLF's production environment with faucets for PCI/PAY tokens. Notable is the Merchant Analytics API—providing anonymized transaction data for dApp development—and Web3 ID toolkit for incorporating Account NFT authentication.
How does PayProtocol handle regulatory compliance across different markets?
The platform employs a region-layered compliance engine: 1) KYC/AML through Fiat24's banking license for European users; 2) Danal's Korean financial licensing for Asian markets; 3) Mastercard's global payment framework for transaction monitoring. Smart contracts dynamically apply jurisdiction-specific rules, for example, PCI↔fiat conversions trigger enhanced ID checks in high-risk regions while maintaining frictionless UX in approved zones.
