Proof of Space (PoSpace) Summary [Cryptocurrency consensus mechanisms]
Proof of Space uses hard disk space as the value used to guarantee a participant’s stake in mining. By allocating disk space, the network participant provides value to the network, which uses this space to solve computational problems. Given low network bandwidth for a lot of regions, making it difficult to transfer large amounts of […]
Proof of Capacity (PoC) Summary [Cryptocurrency consensus mechanisms]
Proof of Capacity (PoC) consensus algorithms require network participants to prove they have performed a certain amount of storage operations in order to mine a valid block. Where Proof of Work consensus requires users to prove they have performed computations in time (to guarantee a 10 minute space between Bitcoin blocks, for example), Proof of […]
Opinion: Decentralized blockchains can only survive having a valuable token, like Bitcoin, attached to them [Feb 2018]
We’ve heard this time and again, especially from folks in the financial sector: “blockchain is here to stay, Bitcoin not so much”. Is this really so? We disagree, and in this article we discuss the origins of Bitcoin and how the problem it solved only makes sense when there’s a reward for participants to join […]
ELI5 Proof of Stake (PoS) – How does PoS work?
In the cryptocurrency universe, Proof of Stake (PoS) is one of the most popular alternatives to the Proof of Work (PoW) family of consensus mechanisms. While PoW systems invest large amounts of energy to make sure transactions are legit, PoS does not require mining hardware. Proof of Stake “miners” (stakers) must lock a financial stake […]
