Elrond is a complete rethinking of public blockchain infrastructure, specifically designed to be secure, efficient, scalable and interoperable. Elrond’s main contribution rests on two cornerstone building blocks: 1) A genuine Adaptive State Sharding approach: effectively partitioning the chain state into multiple shards, handled in parallel by different participating validators; 2) Secure Proof of Stake consensus mechanism: an improved variation of Proof of Stake (PoS) that ensures long term security and distributed fairness, while eliminating the need for energy intensive PoW algorithms. Our technology is aimed at developers, wide public and enterprises. Developers can use it to create decentralised applications and run smart contracts on our blockchain network. The wide public can use Elrond as a user-friendly gateway to the digital economy. Elrond is also attractive for businesses seeking an enterprise solution that can lower (human capital based) costs with benefits such as speed, security and scalability.
