Before we dive deep into how plotting works we need to get familiar with all different terms used in the procedure.

Shabal

Shabal is the name of the crypto/hash function used in Burstcoin. Shabal is a rather heavy and slow crypto in relation to many other like i.e. SHA256. Because of this it makes it a good crypto for Proof of capacity coins like Burstcoin. This is because we store the precomputed hashes while it is still fast enough to do smaller live verifications. Burst uses the 256bit version of Shabal also known as Shabal256.

Hash / Digest

A hash or digest in this context is a 32Byte (256bit) long result of the Shabal256 Crypto.

Nonce

When generating a plot file, you generate something that is called nonces. Each nonce contains 256Kilobyte of data that can be used by miners to calculate Deadlines. Each nonce will have its own individual number. This number can range between 0-18446744073709551615. the number is also used as a seed when creating the nonce. Because of this each nonce has its own unique set of data. One plot file can contain many nonces.

Scoop

Each nonce is sorted into 4096 different places of data. These places are called scoop numbers. Each scoop contains 64byte of data which holds 2 hashes. Each of these hashes are xored with a final hash (we get to final hash in generating a nonce chapter).

Account ID

When you create your plot file it will be bound to a specific Burst account. The numeric account ID is used when you create your nonces. Because of this all miners have different plot files even if they use the same nonce numbers.
