Block version number

The version number is basically telling the wallet what a block can contain and how it is contained. This number changes each time a block gets a new format.

List of Transaction ID

A List of all transaction IDs that are included in this block

Payload Hash

This is the Sha256 hash of all the data in the payload of the block

Timestamp

A timestamp that will describe when the block was forged; derived from the birth of the blockchain. Birth date: 11 August 2014, Time: 02:00:00

Total amount of coins

This is the sum of all transactions in the block

Total amount of fees

This is the amount of fees that will be given to the block forger for generating this block.

The length of the payload

This is a number in bytes representing the length of the payload.

Public Key

This is a public key for the account that forges the block.

Generation Signature

The 32byte generation signature that was used to forge the block.

Previous block hash

A Sha256 hash of the contents from the previous block.

Previous block ID

This is the first 8 bytes in the previous block hash converted to a number.

Cumulative Difficulty

Used to prevent Nothing at Stake problems during potential forks. Calculated: Previous Cumulative Difficulty + (18446744073709551616 / base target)

Base Target

The base target used when forging this block

Height

This block’s height value

Block ID

This is the first 8 bytes in block’s hash converted to a number

Nonce

The nonce number used to forge this block.

AT

If an AT is added to this block, this is the payload bytes for that AT.

Block Signature

This is a 64byte hash generated with the forger’s private key and block contents. When this is done, it will be announced to the network. The wallet will connect to all peers and send the block over to them. The peer will receive the block and verify that all information is not spoofed.
