How long does it take to farm a block?
Your success in farming Subspace Credits will be determined by the amount of storage space you have allocated to the network.
During the initial phase of the Aries testnet, everyone was required to archive one (1) full copy of the history of the blockchain (during the stress test challenge, the size of this history was approximately 5 gigabytes.)
This meant that everyone on the network was allocating the same amount of storage space, 5 gigabytes, and therefore everyone had an equal chance of winning the next block.
With a 6 second block time, and 1,000 nodes for example, it should take on average 6,000 seconds or 1 hour and 40 minutes for every one of the 1,000 nodes to win an additional block. Of course there are slight variations due certain factors like network speed and connectivity and luck, but over the course of time this calculation should hold true.
Since every farmer only had the option to store one (1) full replica of the blockchain history, there was no way to increase your chances of farming a block. That is why we created multi-replica farming.
With multi-replica farming you will be able to store multiple copies, or replicas, of the blockchain history. If you want double your chances of winning a block by allocating 10 GB instead of 5 GB, you will be able to by storing two (2) whole copies of the blockchain history.
The same situation works in the opposite direction. With partial replica farming, if you want to only allocate 1 GB to the network, and the size of the history is 5 GB, you will only store a partial replica of the history. In this case you will have a 20% chance of winning a block compared to someone who allocates 5 GB.
