Bitcoin is the first crypto-asset developed based on a blockchain, the consensus protocol used for its mining process is the Proof of Work, which proved to be very efficient at the moment, but later it would also show its big disadvantages. This protocol is part of the group of consensus protocols that require an effort from the participants in the sorting to determine who proposes the next block of the chain.
Bitcoin’s Proof of Work works by performing some kind of work with a cost that is easily verified by the server, which consists of making a calculation in the customer’s computer in order to prevent undesired behaviors. However, these conditions to operate the PoW are what represent the greatest disadvantages to mine BTC, due to the excessive energy consumption that computers require to do the calculations while looking for the hash, and the need for expensive equipment.
Proof of Play (PoP) is one of the alternative algorithms that have been developed to counter those disadvantages that mining Bitcoin and cryptocurrencies in general present. This protocol could be considered derivative of the Proof of Stake (PoS), which looks for the validation of blocks and generating crypto-assets through the assignment of challenges through a game and, instead of trusting the work performed by computers, it’s based on the work performed by the user through the game.
Instead of looking for an algorithm, PoP tries to find an entry to the game, so that the level generated pseudo-randomly from the block can be completed with this entry. Rather than comparing the hash with the objective value, it verifies the time it took to complete the level. In PoP mining, currencies can only be extracted by the load of cognitive work, being participating in a game the case here.
However, this protocol hasn’t been strongly consolidated in the market, as its main problem are the possible security failures, that’s the reason why this alternative hasn’t succeeded as prior ones.
Looking for a protocol that’s free of the disadvantages that the consensus protocols in general present, the Proof of Achievement, PoAch, emerges. A protocol developed for the Arian blockchain, which is the result of the impeccable fusion between the PoW and PoP, from which their best features are taken to create a protocol that has as a primary feature the human-machine symbiosis, to achieve the best usage of the interaction between a user and the device.
This results in a decrease in the need for expensive equipment and less energetic wear. PoAch makes mining possible from any device, from anywhere and with such simple activities as the participation in a videogame or any activity carried out from a device connected to the Internet of Things.
Arian’s Proof of Achievement (PoAch) has chosen carefully the best from the Proof of Play and the Proof of Work, raising a strategy in which the work developed by the man on the machine (i.e., computer or mobile device) is rewarded once the goal raised by the proposed challenge is achieved. That is, anyone who spends time performing the activity can get to achieve the block’s validation and thus be the winner, which will invariably translate in a real cryptocurrency reward, arians in this case.
