What is Proof of Space ?
Proof of Space (#PoS) is a consensus #algorithm used in some cryptocurrencies to validate transactions and add new blocks to the blockchain. It is a type of proof-of-resource consensus #mechanism, similar to Proof of Work (#PoW) and Proof of Stake (#PoS), or Proof of Capacity (PoC), but it uses hard disk space as the resource instead of computing power or #stake.
In #PoS, participants contribute their unused hard disk space to the network, and the space is used to generate #cryptographic hashes. The more space contributed, the #higher the chance of being selected to validate transactions and earn #block rewards. To participate in the consensus process, participants must first allocate a certain amount of disk #space and generate a proof that they have stored a specific set of data on that space. This proof is then validated by the network, and the participant is added to a #pool of eligible validators.
Once a participant is selected to validate #transactions and add a new block to the blockchain, they must provide a valid #proof of space for the block to be accepted by the #network. The process of generating a valid proof of space typically requires less energy and computational resources compared to PoW, as it relies primarily on the #storage of data on hard drives.
So, What the Difference between the Proof of Stake and Proof of Space ?
In #PoC, #miners create plots, These plots are stored on the miner's hard drive. When a new #block is to be created, miners use their plots to find the solution to a #mathematical problem, and the miner who finds the solution first gets to create the next #block and receive a #reward in the form of #cryptocurrency BUT in Proof of Stake, It uses #hard disk space as the resource instead of #computing power or #stake.
