Blockchain-Empowered Mobile Edge Intelligence, Machine Learning and Secure Data Sharing


Aggelos Kiayias. The advent of the Bitcoin system in brought forth the promise of blockchain technology in Information Technology IT services. Nevertheless, the reality of Bitcoin and its numerous spin-off systems using the same underlying technology was and continues to be fraught with problems in multiple domains including energy efficiency, decentralization, scalability, privacy, programmability and regulatory compliance. To start with, the problem of energy efficiency is particularly jarring.

Bitcoin by itself currently has an annualized energy expenditure on a par with a whole country as large as Argentina. Similarly grim statistics are reflected in its carbon footprint and electronic wastage.

This motivated our work at the lab towards the design of new blockchain protocols that can achieve a similar level of decentralization and inclusiveness as Bitcoin but at a negligible fraction of the cost.

The resulting protocol resulting from our efforts together with our industry partner IOHK, was the Ouroboros suite of blockchain protocols. The work appeared in the flagship conferences of the International Association for Cryptologic Research , and its energy requirements can be as much as six orders of magntitude better compared to the Bitcoin blockchain.

This was achieved with groundbreaking advances in blockchain design that demonstrated how to securely employ a proof of stake blockchain discipline, as opposed to the proof of work approach used in the Bitcoin blockchain.

Decentralization is naturally one of the most critical problems in open distributed ledgers. Bitcoin has, in the course of its history, frequently come under intense scrutiny due to its tendency to centralize to large mining pools e. The developed mechanism was the first proven to exhibit equilibrium configurations that can be highly decentralized. One of the Ph. The mechanism has been deployed at the core of the Cardano ledger and verified its theoretical underpinnings yielding a thriving population of thousands of node operators active pools.

The same is true for related systems like Ethereum. Designing a multi-layered protocol stack that enables responsive transaction processing without sacrificing any of the underlying security and resilience characteristics has been an attractive direction e. Still, this was without definitive evidence regarding its ability to cover all the important use-cases of blockchain technology.

In work, recently published at the Financial Cryptography and Data security conference where the Blockchain Technology Lab had a record number of accepted papers , we proposed a novel layer 2 protocol, termed Ouroboros Hydra, that can achieve transaction processing reaching the physical limits of the underlying communication network while achieving isomorphic functionality to the main chain protocol it depends on.

Hydra has been proposed to be implemented into the Cardano ledger in Perhaps some of the earliest downsides of Bitcoin is its questionable privacy profile. While one need not reveal their identity to create a Bitcoin account, all transactions they perform are publicly shared and their spending patterns are directly reflected in the blockchain.

This left the crucial question whether it is at all possible to design distributed ledgers that are open and energy efficient while preserving the privacy of the participants. We answered this question in the affirmative with our extension of the Ouroboros protocol, Ouroboros Crypsinous, which was also the topic of the Ph. The key novelty was a new way to integrate succinct arguments of knowledge SNARKs with blockchain design.

Ouroboros Crypsinous is currently not implemented in Cardano, but with our research on the topic of cross ledger communication, which was the focus of another Ph. Programming errors in the context of a distributed ledger can be catastrophic. The infamous DAO debacle that plagued the Ethereum blockchain in was a programming bug. It goes without saying that developing programming environments that are conducive to safe and sound programming practices is of paramount importance.

This work is the topic of another Ph. Phil Wadler, also a co-investigator at the lab. The system has the potential to provide a much more principled and verifiable way to build decentralized applications. It is currently implemented within the Cardano blockchain and will serve as the foundation of its functional programming language which was co-developed and analyzed, among others, also by former lab member Chad Nester.

Finally, regulatory compliance has been and continues to be an important obstacle towards the adoption of novel distributed ledger infrastructure for financial services and other applications that are subject to regulatory oversight. The term decentralized finance, or DeFi, recently emerged to label this new class of financial technology applications that are made feasible by utilizing blockchain protocols.

While regulatory hurdles exist, the underlying technology has also an excellent potential for improving regulation compliance and effectiveness. Interdisciplinary work at the lab between Law and Informatics, jointly with Prof. Emilios Avgouleas, has highlighted this direction and systems like Cardano stand to benefit by adopting a regulatory friendly approach that will enable their interoperability with existing financial and e-government infrastructure. While there are many exciting open questions that remain in all the directions mentioned in this post, the above summary is a testament to the substantial strides the Blockchain Technology Lab has made over the last few years.

Our team has been very productive, contributing to 45 publications over the last four years, many in the most competitive venues in Cyber Security and Cryptography.

Security and Privacy on Blockchain-based AI

Blockchain transactions are recorded by multiple users, rather than by paid - and often costly - intermediaries. The model is currently best known for underpinning the functioning of digital currencies, such as Bitcoin. The committee approved on Wednesday recommendations on how to apply the blockchain model elsewhere, so as to cut intermediation costs for small firms, empower citizens and enable the EU to become a global leader in this field. Citizens could use blockchains to gain full control of their own data and decide what to share, and small firms and innovative start-ups could use them to cut intermediation costs and ensure that transactions are executed efficiently, the approved text says. MEPs advocate applying the blockchain model to areas such as energy consumption, health care, supply chains, transport, finance and the creative industries.

This relatively not-so-new blockchain technology is gaining major traction in the business world for the myriad possibilities it offers for.

Applications based on these technologies are either being developed or adopted by insurance companies. While applications based on cloud computing, telematics, and big data are already having a significant impact on the insurance industry, further applications from big data, AI, and blockchain will have a greater impact in the future. Insurers with strong technology capabilities could export their technologies to other insurance companies, financial services companies, or even non-financial services companies. ZhongAn Technology, a subsidiary of ZhongAn Insurance — the first insurer managing 6 billion policies in the cloud — was launched to export such expertise.

With the advent of the "Smart Healthcare" era, a series of cutting-edge technologies has brought new experiences to the management of chronic diseases.

Emerging technologies are technologies whose development, practical applications, or both are still largely unrealized, such that they are figuratively emerging into prominence from a background of nonexistence or obscurity. These technologies are generally new but also include older technologies that are still relatively undeveloped in potential, such as gene therapy which dates to circa but even today still has large undeveloped potential. Emerging technologies are often perceived as capable of changing the status quo. Emerging technologies are characterized by radical novelty in application even if not in origins , relatively fast growth, coherence, prominent impact, and uncertainty and ambiguity. In other words, an emerging technology can be defined as "a radically novel and relatively fast growing technology characterised by a certain degree of coherence persisting over time and with the potential to exert a considerable impact on the socio-economic domain s which is observed in terms of the composition of actors, institutions and patterns of interactions among those, along with the associated knowledge production processes. Its most prominent impact, however, lies in the future and so in the emergence phase is still somewhat uncertain and ambiguous.

Blockchain and Artificial Intelligence are two technologies which, when merged, can help each other unleash their true potential. Blockchains can secure the availability and seamless access to integrity-protected large data sets, from various domains, thus facilitating the effective and more profound learning of AI algorithms. Similarly, AI can be utilized to introduce new consensus mechanisms, and therefore, new ways of interacting with Blockchains. However, when it comes to processing sensitive data, like corporate, healthcare and finance data, several security and privacy concerns arise that should be carefully considered. The interaction with Blockchains is subject to data credibility checks, data leakages related to transaction linkability, compliance with data protection regulations, on-chain data privacy, and malicious smart contracts.
