Is sessia based on blockchain? I mean it is just an app for cashback, where is blockchain here?
As I understand it, Sessia tokens are based on Ethereum blockchain and all transactions are saved in the blockchain, as it happens in other projects. This is information from the official site of the project: "All transactions using Kicks are processed on blockchain technology, which ensures maximum security and safety."
For more information please read Sessia WP.
Here is a part of text for you: " We will create Sessia based on a solution with a big-data database (like
Corda and Bigchain). Then we’ll add blockchain characteristics including
decentralization, immutability and built-in support for creation & transfer of Kicks as
well as all relevant info needed for loyalty programs (like SKU#, aggregates and
promotional campaigns). The proposed solution should have a two-layer
consensus. The lower level (MongoDB, Cassandra, etc.) handles transaction
ordering and crash faults and can be very fast. The higher level (Sessia nodes)
handle double spends and malicious attacks and employs BFT consensus
mechanism (like Tendermint)."
