Proof of stake

Proof-of-stake (PoS) protocols are a class of consensus mechanisms for blockchains that work by selecting validators in proportion to their quantity of holdings in the associated cryptocurrency. This is done to avoid the computational cost of proof-of-work schemes. The first functioning use of PoS for cryptocurrency was Peercoin in 2012. (Wikipedia).

The Quotient Rule: Proof

This video explains and proves the quotient rule as seen in A Level mathematics and beyond. I do "borrow" a result that I don't prove, so this proof lacks a little rigour, but I'm hoping the trade-off is the video will be easier to understand. Introduction:

Bitcoin Q&A: The Game Theory of Staking

Is proof-of-stake just an elaborate Rube Goldberg machine? Is it possible for an attacker to simply buy up all the stake on a network? Could a competing network be incentivized to do this? Can staking and DeFi co-exist? Can DeFi harm a staking network by offering better returns? In this cl

Proof-of-Work — Waste of energy or useful?

Bitcoin mining uses proof of work to determine its supply issuance. Many people believe proof of work should be replaced by proof of stake due to its energy usage. But is that really the case? There is a whole other side that believes proof of work is useful. Who is right? â‚¿ Donate using

Bitcoin Q&A: Governments vs. Proof-of-Work or Proof-of-Stake

If multiple governments collaborated, could they launch a 51% attack on Bitcoin? If all it takes to attack a proof-of-work (PoW) network is enough electricity, wouldn't you want the game theory of delegated proof-of-stake (DPoS), or a hybrid system? Could chainlocks prevent 51% attacks? C
