Proton Blockchain is a public blockchain platform with smart contract and (P2P) peer to peer payments functionality. Its native token cryptocurrency is XPR. The Proton Blockchain is designed to communicate with banks, payment processors and traditional fiat gateways through Proton Signing Request (PSR) with 0 gas fees. Proton Blockchain utilizes a decentralized consensus mechanism called Delegated Proof of Stake (dPoS). This mechanism balances performance with decentralization by relying on a minimized set of active Block Producers voted on by stakers of the native network asset, XPR.
History
Proton (XPR) is a public blockchain and smart contract platform founded in 2020 by Marshall Hayner and Glenn Mariën. The platform is designed for both consumer applications and peer-to-peer payments. It offers a secure and verified identity account that is integrated with a financial settlements layer, allowing users to link their identity with their fiat accounts and buy cryptocurrencies without sharing their sensitive information with merchants. Proton simplifies the process by creating a permissionless layer on top of traditional card networks and banks, eliminating the need for users to share their private keys with merchants. The platform also offers an optional KYC identity store as a security solution. The identity is stored in a PCI-compliant database and can be accessed on the blockchain for identity verification. The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards that companies handling credit card information must comply with to maintain a secure environment.
Proton was originally proposed in a white paper back in 2020, the latest version published in June 2022. This paper described a technique called "proof of stake".[1] The proof-of-stake token allows token holders to stake and bond their tokens in order to vote for block producers. Each token gets a single vote, and there is a 30-day un-staking period as a security measure. The un-staking period is used to evaluate the authenticity and expenses of block producers. The stakers vote for block producers on a one-vote, one-token basis, which can help prevent the double-spending problem. Double-spending occurs when the same digital currency is spent multiple times in a transaction.
May 8, 2020, Proton Mainnet launched with 21 Block producers. The user maintains the private key in confidence while permitting institutions who wish to authenticate the user to check with trusted institutions via public keys. The verification from the trusted institution will confirm the user’s identity without revealing the user’s associated private key.
In November 16, 2022, Proton decentralized exchange (DEX) was released.
Trading
Proton is traded under the token (XPR) on Metal Pay, Gate.io, Bithumb, and LATOKEN. Trading pairs for Proton in the market include XPR/USD, XPR/CAD, XPR/AUD, XPR/GBP, XPR/INR, and XPR/PHP. The XPR token of Proton has moderate annual inflation, which provides a short-term store of value for decentralized applications (DApps) and allows for blockchain governance. The smart contract code for XPR is based on the EOSIO dPOS model. EOSIO is a blockchain technology that uses a distributed and deterministic state machine to track transactions within a series of interconnected blocks.
