Libra - A Future Global Currency By Facebook
  • Name - Libra.

  • Mining rights to - Libra Association’s people only.
  • Property planning and development - Centralized.

The Libra association believes that the exchange of e-money should be safe and smooth. They have introduced a frictionless, safe, and secure way of sending and receiving assets which are even more secure way than normal messages and text are sent by.
Libra’s motto is to empower people by providing them global currency and financial infrastructure. Libra is made of three main parts which will work as a coupled financial system.

  2. It is backed by a reserve of assets designed to give it intrinsic value.
  3. It is governed by Libra Association.
It is built on “Libra Blockchain.” Talking about acceptance of Libra, the Libra association states that everyone has to trust a new trend of crypto called Libra and people need to have confidence that Libra will be a good choice for them as it secure and governed by semi-governance(Libra Association), and accepted by the government of UK central banks.
To have a stand in the digital currency market Libra will need partners companies which will push it and encourage people to use Libra as a global digital currency. The initial group of Libra consists of companies classified as below,

    • Move programming will provide sender and receiver instant proof by showing transaction’s effect on their wallets in no-time.
    • Byzantine fault tolerance will make Libra decisions stronger as it takes every individual’s view over any situation.
    • By using this algorithm association will build trust because BFT is designed to function correctly even if some validator-nodes are compromised or failed.
    • The adopted blockchain data structure will allow everyone to go through the details they need to know and will allow them to check the integrity of the data.
    • This all will be done by following some kind of authorized access to data and abstraction approach for any entity connected with Libra association. I.e- Developer,customer,managers.
