ælf is a decentralized cloud computing blockchain network with high performance, resource isolation, and a more complete governance and development structure. In ælf's network, nodes are divided according to type, and specialized bookkeeping nodes (full nodes) can run on server clusters to improve the performance of the entire blockchain network; the "main chain + multi-side chain" structure effectively realizes resource Isolation, "one chain, one scene"; establishment of a token holder's entrusted voting system to ensure efficient governance and healthy development of the network.

ELF is mainly used for ælf's paid resource payment and governance decision-making. Paid resources include smart contract deployment, upgrade, and execution operations (such as transaction fees, cross-chain data transmission fees, etc.), and governance decisions include bookkeeping nodes elections, approval of new system features, and decisions on major product updates.

1. Project technology application

1. Improve system performance
ælf adopts the DPOS consensus mechanism and uses a small number of nodes for parallel processing to speed up block verification and transaction packaging. Secondly, when a chain becomes too complicated If it cannot be effectively processed, it will be divided into several parallel chains to divert; in addition, ælf will define and trigger the mechanism of system snapshots. After reaching a specific period, a snapshot will be taken of the current data, and then discarded. Detailed transaction data to alleviate the problem of system expansion.

2. Provide consortium chain templates
ælf provides a model similar to cloud services, users can quickly create an independent chain based on consortium chain templates, and exclusively handle their own business .

3. Main chain + multi-side chain structure
ælf is a "branch ecosystem", and the main chain serves as the backbone of the entire system to index multiple side chains. ælf's side chains include system-built side chains and other side chains created based on the ælf OS kernel. The main chain interacts with side chains through dynamic indexing.

4. Realize cross-chain interaction
The cross-chain interaction between ælf and Bitcoin, Ethereum and other mainstream chains will be realized through messages, and based on the cross-chain interaction, a natural Multi-level cross-chain structure, so that digital assets, users and information can be shared.

5. Sidechain dynamic index
ælf is a dynamic system, and chains interact through the Merkle Tree of the main chain and the input verification of external messages.

2. Project Highlights

1. High performance: ælf's full node can run on a server cluster
2. Resource isolation: Each smart contract has its own block Chain
3. Governance & Development: Entrusted voting system for token holders
