Proof of Bid as Alternative to Proof of Work

2020
Proof of Work (PoW) protocol for cryptocurrency uses an excessive amount of electricity to secure the network. Many PoW coins do not have sufficient hashing power to secure itself. There are many alternatives to PoW, such as Proof of Stake (PoS), merge-mining etcetera, which uses much less electricity.

When Proof of Work Works [PDF]

SSRN Electronic Journal, 2006
Proof of work (POW) is a set of cryptographic mechanisms which increase the cost of initiating a connection. Currently recipients bear as much or more cost per connection as initiators. The design goal of POW is to reverse the economics of connection initiation on the Internet.

Proof of Work Without All the Work

Proceedings of the 19th International Conference on Distributed Computing and Networking, 2018
Proof-of-work (PoW) is an algorithmic tool used to secure networks by imposing a computational cost on participating devices. Unfortunately, traditional PoW schemes require that correct devices perform computational work perpetually, even when the system is not under attack.We address this issue by designing a general PoW protocol that ensures two ...

Incremental Proofs of Sequential Work

2019
A proof of sequential work allows a prover to convince a verifier that a certain amount of sequential steps have been computed. In this work we introduce the notion of incremental proofs of sequential work where a prover can carry on the computation done by the previous prover incrementally, without affecting the resources of the individual provers or ...

On (Multi-stage) Proof-of-Works

2021
In this paper we analyze permissionless blockchain protocols, whose distributed consensus algorithm lies on a Proof-of-Work composed of \(k > 1\) consecutive hash-puzzles, that have to be solved sequentially. Our contribution is twofold. First, under common assumptions in the literature, we provide a closed-form expression for the mining probability of

Proof of Work

2020
The primary goal of this chapter is to clearly explain how blocks are mined in a blockchain. Indirectly, this explains how new currency comes into being, as well as how disparate people forming a network can all reach consensus (agree on the state of the blockchain).
