very interesting reading

Typically what happens on the SunContract marketplace is that producers are able to sell their surplus generation at a higher price than the regular (and ever decreasing) feed-in tariffs, while consumers lower their energy costs, buying energy at a lower rate than if they sourced it from retail energy suppliers.

But how can we establish trust without utilities?

A traditional solution in energy has been to use a central point of authority, also known as the energy utility, who acts as the trusted intermediary between energy consumers, electricity generating entities and other agencies involved in the process of power distribution.

At SunContract, we felt that this central management of utilities may not be the most efficient nor desirable way to go about energy management, as it introduces unnecessary intermediary costs to both consumers and prosumers, and requires energy customers to trust a third party to operate the system. We also felt that this centralised system has significant disadvantages due to a single point of failure, which can renders it more vulnerable to technical failures.

The primary purpose of blockchain technology is therefore to remove the need for such intermediaries and replace them with a distributed network of digital users who work in partnership to verify transactions and safeguard the integrity of the ledger. Contrary to centralised systems, every member of the blockchain network holds his own copy of the ledger or can access it in the open cloud. As a result, anyone in the network can have access to the historic log of the system transactions and verify their validity, enabling a high level of transparency. On the SunContract platform for example, users have access to their hourly transactional data, and they can verify the data provided on the platform using the blockchain explorer that is integrated into the platform.
