FINL CHAIN is a smart contract and blockchain application platform with advanced consensus algorithm and enhanced security, overcoming the limitations of the existing platforms. Increasing the transaction speed is a challenging task because of the complex computation involved in storing and validating transactions. In the process of considering double-spending issue, independent network operation, and security problems of blockchain mainnet, the development of the mainnet is often conducted without considering scalability. FINL CHAIN effectively solves the blockchain trilemma by providing all three properties that include scalability, decentralization, and security. Therefore, FINL CHAIN is considered a competitive blockchain model because it solves issues that are not addressed by other existing platforms.


Secure platform

The network is structured to prevent hacking through the VPOS protocol and the PRR formula verifying the trust process between the consensus nodes of the blockchain, and to implement the "autonomous decision-making" for the effective operation of the security network of the blockchain mainnet. The strongest security available is the operation of whitelist policies. However, the operation of whitelist policies increases the complexity of IT resource operations. Therefore, FINL CHAIN operates as an active whitelist system, contributing to the improvement of policy blockchain platform, such as Patch and Fork, and structured it into a secure network system.

Dualized blockchain structure

When storing transactions in blocks, we are duplicating them to separate the nature of financial transactions from the nature of smart contract. This dualization helps to separate and expand the storage structure and improves the efficiency of the block's confidence in storage speed. In synchronizing the storage of all the blocks in the transaction, various dualized storage operations and storage structure management, such as extended storage operations, depend on effectively achieving the work flow continuity of the storage system. It is designed as a model that increases the efficiency of storage structure operation and will contribute to improving the storage structure scalability of existing blockchain.

High-frequency trading technology

The transaction validation, such as the public key and the authentication key stored in the nodes of the block chain, utilizes the network's many traffic resources. By increasing the hash rate of participation in operations on block proofs in most cryptographic transaction processing, the hacker's cost is no more than 51% of the P2P proof network. In FINL CHAIN, to increase the cost of these hackers and make it difficult to damage the P2P network, reputation information of stable communication network and interpretation of trust node participating in agreement are interpreted as related to specific qualifications. This enables the advanced cryptographic network transaction environment to be operated in accordance with the conditions of the high frequency transaction-based network.
