Optimal Threshold Signatures in Bitcoin
We formulate the design of a threshold signature scheme as made possible on cryptocurrency protocols like Bitcoin. The funds are secured by an m-of-n threshold signature, where at least m signatures are needed to unlock the funds. A user designs this scheme knowing that a malicious attacker can also obtain the signatures with some probability. Higher thresholds offer more security, but also risk locking the user out of his own funds. The optimal threshold balances these twin effects. Interventi…

Good Morning #Canada
We are firmly launched into October, and it's safe to start thinking about #Halloween. So, a new semi regular series on Canada’s abandoned and spooky towns seems appropriate. Today's town is Barkerville in British Columbia, where wolves howl night and day. OK, maybe not, but there's definitely some stalking of tourists in the once bustling gold rush town. After the Caribou Gold Rush ended and town residents drifted away, Barkerville was designated a historic site, and most of the buildings were preserved. Today, it's one of the largest heritage parks and museums in North America. There are hundreds of people in old timey clothes walking about, but they're not ghosts, just park staff. But the prices are scary.
A good ghost town runner-up would be Ocean Falls, abandoned after the pulp mill closed, but a sinister and mysterious Bitcoin operation still utilizes the old hydroelectric dam.

Bitcoin's consensus rules are encoded in the implementation of its reference client: "The code is the spec." Yet this code is unsuitable for formal verification due to side effects, mutable state, concurrency, and legacy design. A standalone formal specification would enable verification both across versions of the reference client and against new client implementations, strengthening decentralization by reducing the risk of consensus-splitting bugs. Yet such a specification has long been consi…

The breach was only uncovered in 2025 by Arkham Intelligence, revealing a staggering $14.5 billion worth of stolen assets that had remained untouched and undetected for half a decade

The biggest heist of all time involved over $14 billion of crypto being stolen - and it went undetected for five years

Hybrid GCN-GRU Model for Anomaly Detection in Cryptocurrency Transactions
Blockchain transaction networks are complex, with evolving temporal patterns and inter-node relationships. To detect illicit activities, we propose a hybrid GCN-GRU model that captures both structural and sequential features. Using real Bitcoin transaction data (2020-2024), our model achieved 0.9470 Accuracy and 0.9807 AUC-ROC, outperforming all baselines.

A Game-Theoretic Foundation for Bitcoin's Price: A Security-Utility Equilibrium

A Game-Theoretic Foundation for Bitcoin's Price: A Security-Utility Equilibrium
This paper introduces a structural game-theoretic model to value decentralized digital assets like Bitcoin. Instead of relying on speculative beliefs, it frames the asset's price within a Rational-Expectations Security-Utility Nash Equilibrium (RESUNE). This equilibrium is a fixed point where the market-clearing price dictates the hash rate through a free-entry mining model, which in turn endogenously sets the network's security. The security, defined as one minus the probability of a 51% attac…

Substituting Proof of Work in Blockchain with Training-Verified Collaborative Model Computation
Bitcoin's Proof of Work (PoW) mechanism, while central to achieving decentralized consensus, has long been criticized for excessive energy use and hardware inefficiencies \cite{devries2018bitcoin, truby2018decarbonizing}. This paper introduces a hybrid architecture that replaces Bitcoin's traditional PoW with a centralized, cloud-based collaborative training framework. In this model, miners contribute computing resources to train segments of horizontally scaled machine learning models on prepro…
