Atlas

Middleware for Storing Data on Multiple Blockchains

What it is?

A blockchain is a distributed database that maintains a continuously growing list of ordered records, called blocks. These blocks are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.

Our systems tries to make it simple to create links cross-chains. In other words, it allows blockchains to speak to one another in a standardized way. Cross blockchain compatibility, allows different blockchains to communicate with one another without the help of intermediaries. Instead, people will be able to transact with users from other compatible blockchains. The entire process will take place without any downtime or expensive transaction fees.

How it works?

This API helps a Mobility Observer Agent(MOA) store positioning data on a Blockchain. Each time MOA wants to create a checkpoint in a new region, it sends an id and data to Atlas. The API then creates a structure comprised of the checkpoint, a timestamp, an id, and a reference id and sends it to a lower Blockchain layer. To facilitate possible GET methods, the API stores this data in a database.

Every time a client wants to consolidate a set of checkpoints, it can send the old identification. The API is responsible for retrieving the checkpoints corresponding to the lower Blockchain layer and compiling them on a segment for the upper layer. MOA also sends the compiled data to a local database for API performance.
