It is the state of t+1 (account trie).

It is a state transition function, which can also be understood as an execution engine.

is a transaction

Is a state transition function at the block level.

It is a block and consists of many transactions.

Transaction at position 0.

Is the block termination state transition function (a function that rewards the miner).

The conversion relationship between the various units used in Ethereum and Wei (for example: a Finney corresponds to 10^15 Wei).

Some basic rules

• For most functions, they are identified by uppercase letters.
• Tuples are generally identified by capital letters
• A scalar or fixed-size array of bytes is identified by a lowercase letter. For example, n represents the nonce of the transaction, and there may be some exceptions, such as δ representing the amount of stack data required for a given instruction.
• Variable-length byte arrays generally use bold lowercase letters. For example, o represents the output data of a message call. It is also possible to use bold uppercase letters for some important things.

Byte sequence positive integer byte sequence length of 32 bytes

positive integer smaller than 2 ^ 256, [ ] is used to index array elements which corresponds to the first object represents a stack machine (machine's stack) is representative of the machine memory (machine's memory) the first 32 elements inside a placeholder, any character may be representative of any object

Value representative of the object to be modified intermediate state 中间状态 2 intermediate state 2 if the previous f represents a function, f * represents the back of a similar function, but a function f is sequentially executed for the inner elements.

It represents the final element of the list which is representative of the last element of the list which is
