Remember like three years ago when crypto bros were trying to sell us this big story about how they were going to be friendly demand response players who could accelerate the energy transition by balancing load with supply? (I didn't bite.) Then how it turned out they were running 24x7 and keeping coal plants running that would have otherwise retired? And then how the DOE started tracking their energy consumption? Well, now the crypto bros are blocking DOE.

How To Save Fees in Bitcoin Smart Contracts: a Simple Optimistic Off-chain Protocol
We consider the execution of smart contracts on Bitcoin. There, every contract step corresponds to appending to the blockchain a new transaction that spends the output representing the old contract state, creating a new one for the updated state. This standard procedure requires the contract participants to pay transaction fees for every execution step. In this paper, we introduce a protocol that moves most of the execution of a Bitcoin contract off-chain. When all participants follow this prot…

A Confirmation Rule for the Ethereum Consensus Protocol
A Confirmation Rule, within blockchain networks, refers to an algorithm implemented by network nodes that determines (either probabilistically or deterministically) the permanence of certain blocks on the blockchain. An example of Confirmation Rule is the Bitcoin's longest chain Confirmation Rule where a block is confirmed (with high probability) when it has a sufficiently long chain of successors, its siblings have notably shorter successor chains, and network synchrony holds.

A Holistic Approach for Bitcoin Confirmation Times & Optimal Fee Selection
Bitcoin is currently subject to a significant pay-for-speed trade-off. This is caused by lengthy and highly variable transaction confirmation times, especially during times of congestion. Users can reduce their transaction confirmation times by increasing their transaction fee. In this paper, based on the inner workings of Bitcoin, we propose a model-based approach (based on the Cramér-Lundberg model) that can be used to determine the optimal fee, via, for example, the mean or quantiles, and m…
