LINK is based on an independent blockchain mainnet called LINK Chain, which offers exceptional performance and enough stability to handle the support of dApps to millions of LINE users. LINK Chain is a consortium-type blockchain platform where each participating service constitutes one node in a larger network. It is built on a high-performing blockchain core network that can process more than 1,000 transactions per second in a single thread. LINK Chain reflects LINE’s long experience and know-how in building platform infrastructure.

※ LINK Chain is developed by UNCHAIN CORPORATION, the joint venture of LINE and ICON Foundation.

The nodes of LINK Chain are managed by UNCHAIN CORPORATION, the technical operator of LINK Chain. UNCHAIN CORPORATION plays the role of developing and managing blockchain infrastructure technology by maintaining its neutrality within the LINK ecosystem and prioritizing safe management of the LINK Chain nodes.

What is the consensus algorithm of LINK Chain?

LINK Chain supports prompt consensus based on the LFT (Loop Fault Tolerance) algorithm supporting BFT (Byzantine Fault Tolerance). In addition, it can achieve consensus a little faster by binding a number of nodes in a trusted relationship into one group based on LFT.
