The Blockchain.io project is a centralized exchange with decentralized calculations that offers both liquidity and stronger security.
This is a new generation of exchange platforms that combines the technology of centralized depository exchange with a decentralized, trust-based cross-chain fair exchange. Centralized exchange will be with low latency and full-featured, with storage services, centralized reservation of orders and effective order matching. Block.cio is a project developed by Paymium. Paymium.com is one of the oldest and safest bitcoins of stock exchanges in the world. Blockshell.io will become a platform for trading crypto-currencies, providing users with a centralized order register and decentralized calculations. The company plans to offer ICO services to entrepreneurs and institutions - from planning and execution to listing tokens on the market, focusing efforts in Europe, where the crypto-currency market lacks transparency and a regulated exchange that would allow institutions to launch ICO. In a word, everything is very wonderful and the project is very good.
