Analyzing the Prospects of Blockchain in Healthcare Industry
| S.no | Name of the algorithm | Year | Invented by | Purpose |
| 1 | Proof of work (PoW) | 1993 | Cynthia Dwork and Moni Naor | Creates new blocks in sequence of chain and also confirm transactions occur in each block. | 2 | Proof of stake (PoS) | 2011 | Sunny king | All blocks of chain are validated on the basis of strut of participants of network. | 3 | Delegated proof-of-stake (DPoS) | 2014 | Daniel Larimer | It works like voting system so participants vote to help the state of new block according to validators. | 4 | Proof of burn | 2014 | Lain Stewart | Works to reduce rate of energy consumption. | 5 | Proof of elapsed time (PoET) | 2016 | Intel | All participants of networks will wait for randomly time period, then who finished on time get new block and validates that block. | 6 | Proof of space | 2015 | Dziembowski. | Usage of space instead of computation is predominant in this algorithm rest of the functionality is very same as to proof of work algorithm. | 7 | Delayed proof of work (dPoW) | 2016 | Komodo project | It is a security mechanism that make use of bitcoin blockchain hashpower to enhance network security. | 8 | Proof of authority (PoA) | 2017 | Gavin wood | It delivers comparatively fast transactions through a consensus mechanism. | 9 | Leased proof-of-stake | 2017 | A variant of proof of stake | Any participant has a possibility to lease out their balance to mining nodes and these mining nodes share a profit with participants. | 10 | Proof of weight | 2017 | MIT computer Sc. & AI lab | It is a mechanism that gives users a ‘weight’ based on how much cryptocurrency they are holding. |
