Blockchains, or Distributed Ledger Technologies (DLTs), can become a groundbreaking disruptive technology, capable of profoundly impacting a wide range of markets, from cryptocurrency to novel use cases in both the public sector and the private sector. Blockchains promise the ability to maintain critical information in a trustworthy repository without any centralized management. The reliability of the system is based on innate immutability properties which prevent alteration of stored data, coupled with programmatic verification of incoming transactions using executable code called smart contracts. Blockchains can alleviate friction across users, by providing transparency, efficiency, auditability, and security. Important challenges remain to be solved before blockchain technology can be widely adopted. In particular, blockchain systems suffer from performance and scalability problems. In this project, the main goal is to demonstrate the applicability and improve the utility of DLTs for applications beyond cryptocurrency, specifically in the domain of Internet of Things. We will accomplish this goal through four different vectors: (1) the study of IoT blockchain applications and an analysis of their performance requirements, (2) the design and implementation of technical innovations to various blockchain systems (e.g., Ethereum and Hyperledger Fabric) to raise their performance and scalability, (3) the development of general performance models for blockchain networks, which assist in the decision-making process of selecting the right blockchain solution for each application, and how to optimally tune it, and (4) the design of new infrastructure management protocols for large-scale data centers to efficiently support future IoT applications.As blockchain is still in its infancy, there is a tremendous chance for Canada to become a leader in its development. The research outcomes of this project will lead to greater adoption of blockchain technologies across a variety of industrial and social sectors. Furthermore, the project will train at least 8 graduate students to meet the growing demands for highly skilled blockchain experts.

区块链或分布式账本技术（DLT）可以成为一种突破性的颠覆性技术，能够深刻影响广泛的市场，从加密货币到公共部门和私营部门的新用例。区块链承诺能够在一个值得信赖的存储库中维护关键信息，而无需任何集中管理。该系统的可靠性是基于固有的不变性，防止存储数据的更改，加上使用称为智能合约的可执行代码对传入交易进行编程验证。区块链可以通过提供透明度，效率，可扩展性和安全性来减轻用户之间的摩擦。在区块链技术被广泛采用之前，重要的挑战仍有待解决。特别是，区块链系统存在性能和可扩展性问题。在这个项目中，主要目标是展示DLT的适用性，并提高DLT在加密货币以外的应用程序中的实用性，特别是在物联网领域。我们将通过四个不同的载体来实现这一目标：（1）物联网区块链应用的研究及其性能要求的分析，（2）各种区块链系统的技术创新的设计和实施（例如，以太坊和Hyperledger Fabric），以提高其性能和可扩展性，（3）为区块链网络开发通用性能模型，这有助于为每个应用程序选择正确的区块链解决方案的决策过程，以及如何优化它，以及（4）设计新的基础设施管理协议，大规模数据中心，以有效地支持未来的物联网应用。由于区块链仍处于起步阶段，加拿大有很大的机会成为其发展的领导者。该项目的研究成果将导致区块链技术在各种工业和社会部门的更多采用。此外，该项目将培训至少8名研究生，以满足对高技能区块链专家日益增长的需求。
