The advent of secure public blockchains through Bitcoin and later Ethereum, has brought forth a notable degree of interest and capital influx, providing the premise for a global wave of permissionless innovation. Despite lofty promises, creating a decentralized, secure and scalable public blockchain has proved to be a strenuous task. 

This paper proposes Elrond, a novel architecture which goes beyond state of the art by introducing a genuine state sharding scheme for practical scalability, eliminating energy and computational waste while ensuring distributed fairness through a Secure Proof of Stake (SPoS) consensus. Having a strong focus on security, 

Elrond’s network is built to ensure resistance to known security problems like Sybil attack, Nothing at Stake attack and others. In an ecosystem that strives for interconnectivity, our solution for smart contracts offers an EVM compliant engine to ensure interoperability by design. 

Preliminary simulations reflect that Elrond exceeds Visa’s average throughput and achieves an improvement beyond three orders of magnitude or 1000x compared to the existing viable approaches, while drastically reducing the costs of bootstrapping and storage to ensure long term sustainability
