Coin specifications

The Orbitcoin technical design is unique.
It differs from any other cryptocurrency in the world.
 
 
Keypoints :
 
  • The Orbitcoin consumes less electricty than others currencies ;
  • The Orbitcoin generates interests from holdings ;
  • With a limited total supply of 3.77 million coins, the Orbitcoin is rare.

Proof-Of-Stake
 
Orbitcoin's major distinguishing feature is that it uses proof-of-stake/proof-of-work hybrid system. The proof-of-stake system was designed to address vulnerabilities that could occur in a pure proof-of-work system. For example, there is a risk of 51% attacks in Bitcoin or Litecoin resulting from a monopoly on mining power (a 51% attack is when a single entity possesses over a half of the network hash power), which would possibly allow this entity to double spend coins. With a proof-of-stake system, a network attacker would also need to gain a large quantity of coins. This has the effect of making a monopoly more costly, and stops the risk of a monopoly from proof-of-work mining shares.
 
PoW and PoS blocks carry the same fixed reward of 1 ORB.
The 1st implementation of fixed PoS block rewards.
