 0G Storage is the storage layer for the ZeroGravity data availability (DA) system. The 0G Storage layer holds three important features:
 
-* Buit-in - It is natively built into the ZeroGravity DA system for data storage and retrieval.
+* Built-in - It is natively built into the ZeroGravity DA system for data storage and retrieval.
 * General purpose - It is designed to support atomic transactions, mutable kv stores as well as archive log systems to enable wide range of applications with various data types.
 * Incentive - Instead of being just a decentralized database, 0G Storage introduces PoRA mining algorithm to incentivize storage network participants.

 # Proof of Random Access
 
-The ZeroGravity network adopts a Proof of Random Access (PoRA) mechanism to incentivize miners to store data. By requiring miners to answer randomly produced queries to archived data chunks, the PoRA mechanism establishes the relation between mining proof generation power and data storage. Miners answer the queries repeatedly and computes an output digest for each loaded chunk util find a digest that satisfies the mining difficulty (i.e., has enough leading zeros). PoRA will stress the miners' disk I/O and reduce their capability to respond user queries. So 0G Storage adopts intermittent mining, in which a mining epoch starts with a block generation at a specific block height on the host chain and stops when a valid PoRA is submitted to the 0G Storage contract.

 In a strawman design, a PoRA iteration consists of a computing stage and a loading stage. In the computing stage, a miner computes a random recall position (the universal offset in the flow) based on an arbitrary picked random nonce and a mining status read from the host chain. In the loading stage, a miner loads the archived data chunks at the given recall position, and computes output digest by hashing the tuple of mining status and the data chunks. If the output digest satisfies the target difficulty, the miner can construct a legitimate PoRA consists of the chosen random nonce, the loaded data chunk and the proof for the correctness of data chunk to the mining contract.

 ## Data Flow
 
-In 0G Storage, committed data are organized sequentially. Such a sequence of data is called a data flow, which can be interpreted as a list of data entries or equivalently a sequence of fixed-size data sectors. Thus, every piece of data in ZeroGravity can be indexed conveniently with a universal offset. This offset will be used to sample challenges in the mining process of PoRA. The default data flow is called the "main flow" of ZeroGravity. It incorporates all new log entries (unless otherwise specified) in an append-only manner. There are also specialized flows that only accept some category of log entries, e.g. data related to a specifc application. The most significant advantage of specialized flows is a consecutive addressing space, which may be crucial in some use cases. Furthermore, a specialized flow can apply customized storage price, which is typically significantly higher than the floor price of the default flow, and hence achieves better data availability and reliability.
