Service databases continually synchronised with the blockchain allow to use it as an ordinary database. For this reason developers can give up working directly with the blockchain and open up many opportunities in displaying, sorting out and massive decrypting of information and also use systems of machine learning and artificial intelligence.
TravelChain.io site is using service database developed by the team of TravelChain. When used, data from the blockchain is continuously synchronised with database of MongoDB which provides a wide functional of filters for display. Therefore, a user can resort to a wide functional of filters for information search in the register of TravelChain data.
Any developer can use API of service database, create a functional analogue and use it in a similar or alternative way.
When users work with service database their transactions are transferred from the client directly to the blockchain bypassing centralized services. Therefore, service database does not work with the user in CRUD mode but only in READ mode.
