FON Smart Chain is a brand new public chain. The FON Smart Chain relies on a system of 21 active validators with a Proof of Stake (APoS) consensus that supports short block times and low fees. The validator candidate with the most stake will become a validator and produce blocks. Double-signature detection and other slashing logic guarantee security, stability, and chain finality. In addition to the 21 active validators, FSC will also introduce more validators, such as another 20 inactive validators, as backups into the validator set, which will be called "candidates".
Candidates will generate blocks and collect gas fees in the FSC Mainnet, but have far fewer chances than the formal validator set of 21 elections. Unavailable candidates will also be cut, albeit on a smaller scale. It is expected to remain well motivated so that candidate validators are willing to ensure quality and help secure the FSC In extreme cases, if a majority of the active 21 validators are attacked and taken offline, in the genesis block, the team set A node to ensure the normal operation of the public chain.
The FON Smart Chain also supports EVM-compatible smart contracts and protocols. Cross-chain transfers and other communications are possible thanks to native support for interoperability.
Self-sovereign blockchain：Safety and security are provided through elected validators.
EVM-compSupport for all existing Ethereum tools plus faster finality and cheaper transactions
Interoperable: Comes with efficient native dual-chain communication; optimized for high-performance dApps that require a fast and smooth user experience.
Distributed on-chain governance： Proof of Stake (APoS) brings decentralization and community participation. As a native token, FON will serve as gas for smart contract execution and as a token for staking.
Cross-chain and multi-chain ecosystem
An important lesson to learn from historical data is that "one chain" cannot cover all angles. At its peak, FSC had more than 2 million daily active users (DAU), with a single GameFi reaching 1 million DAU. This creates significant challenges for the network itself and its supporting infrastructure such as RPC/API nodes. For dApps with massive user bases, multi-chain and cross-chain should be the solution.
The FSC core team firmly believes in the future of partitioned chains and multi-chains as it can sustain the ever-increasing demand for decentralized computing power and storage. This is consistent with the multi-chain strategy in many other blockchains in the industry such as ETH2.0 as well as Polkadot, Cosmos and Avalanche.
Cross-shard and cross-chain/multi-chain interoperability will be key topics in 2022. The FSC token and developer community are committed to realizing FSC's vision of operating at the crossroads of the decentralized blockchain future. Specifically, we aim to achieve this by implementing new technologies on FSC through the FON sidechain and the FSC Partition Chain (FPC) infrastructure layer.
