SPoRA #9/20

Succinct Proofs of Random Access is the Arweave consensus algorithm. Arweave is a blockweave data structure where blocks reference both the previous block and a random (recall) block. Miners need access to recall blocks to mine a new block and are incentivized to store and quickly access historical data to increase the probability of success and reward. SPoRA represents a miner randomly accessing blocks in a blockweave and is composed of the "ar_poa.erl" source code from the Arweave protocol.
