- Abstract: The distributed consensus mechanism is the backbone of the rapidly developing
blockchain network. Blockchain platforms consume vast amounts of electricity
based on the current consensus mechanism of Proof of Work. Here, we point out
an advanced consensus mechanism named Proof of Stake that can eliminate the
extensive energy consumption of the current PoW-based blockchain. We
comprehensively elucidate the current and projected energy consumption and
carbon footprint of the PoW and PoS based Bitcoin and Ethereum blockchain
platforms.

We study the interplay between threshold cryptography and a class of blockchains that use Byzantine-fault tolerant (BFT) consensus protocols.
Existing approaches for threshold cryptosystems introduce a latency overhead of at least one message delay for running the threshold cryptographic protocol.
We propose a mechanism to eliminate this overhead for blockchain-native threshold cryptosystems with tight thresholds.

A proof of work (PoW) is an important cryptographic construct enabling a party to convince others that they invested some effort in solving a computational task.
In this work, we examine the hardness of finding such chain of PoWs against quantum strategies.
We prove that the chain of PoWs problem reduces to a problem we call multi-solution Bernoulli search, for which we establish its quantum query complexity.
