RecordsKeeper FAQ

What is RecordsKeeper?

RecordsKeeper is a Open Public Mineable Blockchain for RecordKeeping & Data Security.

You can publish your data in key-value pair format onto the RecordsKeeper Blockchain.

Is RecordsKeeper a Storage, Database or Blockchain?

RecordsKeeper is a key-value pair based database running on Blockchain. It stores every record as a key-value pair as a part of XRK transaction. In another way you can consider it an amalgamation of all the three (Storage, Database & Blockchain) as it offers storage as a Database over the public Blockchain.

How RecordsKeeper is different from traditional storage?

Since RecordsKeeper is Public Blockchain it consist of several decentralized nodes (aka Servers) which verify each and every transaction while adding a new Block into the Blockchain. Each node participates in administration: all nodes verify new additions to the blockchain, and are capable of entering new data into the RecordsKeeper. Traditional Database allows the modification of data but with RecordsKeeper Blockchain the data is secured and cannot be tampered, altered or modified once published & confirmed in the RecordsKeeper Blockchain Ledger.

How RecordsKeeper is different from Storj, Filecoin and Siacoin?

In any case the max size of record published can be upto the maximum size of 2 MB per XRK transaction.
