TravelCoin – payment system based on blockchain technology. It is the answer to fundamental coordination problems amongst payment processes and financial relationships in the tourism business sector. By enabling decentralized exchange currency and user-friendly wallet, TravelCoin will provide a next-generation value transfer service across national borders operating between touristic companies, tour operators, hotels, reservation systems, etc. The TravelCoin payment system will consist of digital TC-wallet (wallet with exchange and messenger functions) and two cryptocurrencies – token TravelCoin (TC, Proof-of-Staked-Authority consensus) and TravelCoin cryptocurrency (TCC, Proof-of-Stake consensus). Both coins will be equivalent in the TravelCoin payment system.
