P2P Exchange

A Peer-to-Peer (P2P) exchange acts like a match-maker or auction service, matching the buyer and seller instead of initiating the trade right away. The matching is done on the basis of the price and what type of payment is accepted by the buyer or seller. After matching, if the buyer gets convinced with the seller’s…

Proof of Authority

In Proof of Authority (PoA), instead of offering up a resource like computing power (PoW) or a financial stake (PoS), Proof of Authority (PoA) relies on validators staking their reputation. Compared to PoW and PoS networks which allow anyone to join without revealing their identity, PoA validators must be known and trusted, thus better suited…

Proof of Stake

What is proof of stake in blockchain technology? The proof of stake consensus model was proposed in 2012 in response to the substantial amount of electricity and energy required to mine a single block under the proof of work model. Unlike proof of work, in a proof of stake model consensus is reached by a…

There is no block reward in PoS. To conduct a 51% attack, you would need to control 51% of the total stake; in proof-of-work, you would…

Proof of Work

What is proof of work in blockchain technology? Proof of work is a consensus model in blockchain technology that requires miners to solve computationally difficult math problems in order to add new blocks onto the blockchain. These functions produce data that is used to validate that a substantial amount of work has been carried out,…

Proof of Work

To add a new block to the chain, miners must compete to solve a difficult mathematical puzzle, using intense computational power via their computers, which consumes energy (electricity). The first miner who solves this puzzle and broadcasts this to the network is rewarded with an amount of Bitcoin (block reward) which is presently 6.25 BTC…
