How do smart contracts enable trustless energy trading and settlement without a central operator?
A set of Trading Smart Contracts acts as a shared, tamper-resistant information board that automatically matches buyers to sellers and settles payments — with no distributor in the middle.
A smart contract is self-executing code on the blockchain. Here, Trading Smart Contracts (TSC) serve as an on-chain information board for the energy auction:
- Each endpoint's Transaction Controller posts its sell offers and buy requests to the board.
- The TSC matches buyers and sellers by price.
- It performs periodic market settlement (e.g. daily), transferring tokens and stabilising supply-demand balance.
Because the contract runs on a ledger jointly maintained by all participants, no single party (like the LPD) controls matching or can quietly favour itself — the transparency, fairness, and automation come from the code and the shared ledger, not from trusting an operator. Offloading this from the LPD is exactly what decentralises the market.
