We are building EduLadder(ELADR) - Protocol

The Eladr Protocol is a decentralized, security and efficiency enhanced Web3 noSQL database powered by IPFS as the data storage layer https://ipfs.io/, and the Cardano block chain as the rewards token platform, https://cardano.org/. It provides a JSON based, IPFS layer 2 solution for data indexing and retrieval in an 'append only' file system built with open source Node.js API libraries.

The ELADR token was designed to incentivize and reward community members as a proof of contribution. Token holders are also granted access to EduLadder.com premium features as well as associated ELADR token enabled apps.

Image result for Explain the concept of ACID properties in DBMS?
In the transaction processing context, the ACID acronym refers to the four primary and essential properties of a transaction. These are atomicity, consistency, isolation, durability. In totality, the ACID properties of transactions provide a mechanism in DBMS to ensure the consistency and correctness of any database.

ACID properties is the combination of Atomicity, Consistency, Isolation, and Durability properties. These properties are very helpful in allowing a safe and secure way of sharing the data among multiple users.

  • Atomicity: This is based on the concept of “either all or nothing” which basically means that if any update occurs inside the database then that update should either be available to all the others beyond user and application program or it should not be available to anyone beyond the user and application program.
  • Consistency: This ensures that the consistency is maintained in the database before or after any transaction that takes place inside the database.
  • Isolation: As the name itself suggests, this property states that each transaction that occurs is in isolation with others i.e. a transaction which has started but not yet completed should be in isolation with others so that the other transaction does not get impacted with this transaction.
  • Durability: This property states that the data should always be in a durable state i.e. any data which is in the committed state should be available in the same state even if any failure or restart occurs in the system.
