DLT for Smarter Energy Communities

DigiBlocks leverages the interconnection between the Internet of Things and Distributed Ledger Technology to enable trusted interaction in smart energy communities.

What is DigiBlocks?

DigiBlocks is funded by the Sustainable Energy Authority of Ireland (SEAI) under their 2018 RD&D Programme, grant agreement number 18/RDD/262. DigiBlocks will provide a suite of tools that provides an integrated innovative solution for district energy management, which considers the interaction and integration between the district buildings, the users/citizens and the wider energy system. The DigiBlocks platform, tools, and pilots considered will illustrate Blockchain’s potential both to upset current business models in the energy sector and to redefine stakeholder positions

DigiBlocks Ambition

DigiBlocks will help facilitate the transformation of the energy sector through digitisation and support the fundamental shift in the energy landscape from a rigid centralised infrastructure towards decentralisation and energy-based communities, motivated in part by the increasing penetration of renewables and need for cities to move towards being positive energy districts.

Extracting Value from Data

To make good decisions you need knowledge, to achive knowledge you need reliable data.

Distributed Ledger Technology

Distributed ledgers provide immutable records of data and interactions between independent entities

Network of Trusted Entities

By being part of a permissioned based Blockchain network enables trusted interaction and shared governance

Novel Applications & Services

DigiBlocks supports the automation of data processes, auditability and interaction between entities
