Columbia University
-----
Blockchain technology creates the abstraction of a “computer in the sky”---a global and shared programmable virtual machine that combines the general-purpose functionality of a computer with the decentralization and fault-tolerance of the Internet. A blockchain protocol plays a role similar to that of an operating system---an intermediate layer that insulates the application layer (i.e., smart contracts) from the hardware layer (i.e., the Internet) and acts as the “master program” that coordinates the execution of all the virtual machine’s system and user-installed programs. Blockchain technology can be viewed as adding state and data processing capabilities to traditional Internet infrastructure and, among other applications, it enables stronger forms of ownership of digital assets than society has ever had before.
Blockchain protocol design requires innovation in and the synthesis of a number of technically challenging fields, including distributed systems, game theory and mechanism design, cryptography, and more. The Columbia-Ethereum Center for Blockchain Protocol Design brings together the multi-disciplinary expertise at Columbia to advance the performance, security, robustness, and economics of this societally important technology.
The Center’s activities include research grants for Columbia faculty, students, and their collaborators; postdoctoral and graduate student fellowships; an industry research-in-residence program; and several events, including the Columbia Cryptoeconomics Workshop and an annual summer school.

Newcastle University; School of Computing; Newcastle, UK
Fully-funded competitive PhD studentship, highly suitable for UK candidates, is available.
Brief Description: Weather forecasting and environmental prediction are vital for managing risks such as flooding, extreme temperatures, and poor air quality. However, most forecasting systems rely on centralised data processing, raising concerns about privacy, data ownership, and resilience to cyber attacks or system failures. These challenges have been largely overlooked in both the UK and globally.
This project builds on recent work by Dr Aydin Abadi and colleagues at Newcastle University, who developed a decentralised weather forecasting framework combining Federated Learning (FL) and blockchain. The approach enables multiple organisations to train shared forecasting models without exchanging raw data. Blockchain ensures transparent model validation, while privacy-preserving methods protect sensitive local observations.
The PhD will extend that research by improving the scalability, accuracy, and security of decentralised environmental forecasting. It will explore advanced cryptographic techniques such as secure aggregation, privacy-preserving consensus, and private set intersection (PSI) to protect participants’ data and evaluate performance on real and synthetic meteorological datasets.
The goal is to deliver a scalable and secure collaborative forecasting framework that strengthens environmental resilience and benefits society.
