Aelf is a decentralised cloud-computing network that has self-evolving governance, utilising a “one main chain + multiple side chains” structure. Aelf is designed to be a complete business solution, allowing developers to run and deploy dApps on these multiple side chains to maximise resource isolation for smart contracts. Aelf adopts a unique Proof-of-Stake consensus mechanism known as AEDPos which achieves high throughput, as well as highly efficient, multichain parallel-processing. Aelf uses scalable nodes and allows for secure and accurate cross-chain communication between the main-chain and the multiple side-chains. The native token of the Aelf network is the ELF token. The ELF token is used as the main incentive system on the Aelf network. The ELF token is also used for the network fees paid by developers or side-chain creators, resource fees for smart-contract deployment and cross-chain data transfers, system upgrades, token-holder voting rights, and for token staking by nodes.
