The technological solutions are provided by the market leader TensorFlow.

UBCOIN MARKETPLACE PRODUCT
Product Value Foundation

Their product is founded on the following cornerstones:

Cryptocurrency mass adoption. They promote mass adoption of digital assets that are both a means of settlement and an investment vehicle, thereby enlarging benefits for all parties to everyday buy-and-sell interactions.
Peer-to-peer interaction. Cut out as many intermediaries from the value chain, as possible. The platform facilitates smart contract execution between independent parties. The Ubcoin Marketplace does not own any goods for sale, it is not biased in its search results, and protects fairness of smart contracts.
Legal marketplace. They pay special attention to ensuring the legitimacy of goods and services sold on the Ubcoin marketplace. They are developing an advanced AI technology to help pre-screen seller postings for any potential infringements of reason, morality, safety and due care. Seller profile transparency and verification will be strongly encouraged and promoted.
Decentralization of transactions and settlements. Blockchain allows for decentralized initiation, settlement and fulfillment of transactions. Payments are immediate upon performance under carefully crafted smart contracts.
Impeccable interface. Their interface design brings a harmonious and seamless experience of buying and selling goods globally. They will strive to open our API to the community in order to develop the best adaptation of the platforms for specific local needs of the global community.
Open community. Some transactions may, in the future, require additional KYC/AML procedures for execution of smart contracts for certain types of deals involving third-party providers (i.e. delivery companies, couriers, notaries). Ubcoin platform envisions seamless engagement of these parties.
