Blocks

This module contains the structure of block storage in the Waves Enterprise blockchain.

Field order number	Field	Type	Field size in bytes
1	Version (0x02 for Genesis block, 0x03 for common block)	Byte	1
2	Timestamp	Long	8
3	Parent block signature	Bytes	64
4	Consensus block length (always 40 bytes)	Int	4
5	Base target	Long	8
6	Generation signature*	Bytes	32
7	Transactions block length (N)	Int	4
8	Transaction #1 bytes	Bytes	M1
…	…	…	…
8 + (K - 1)	Transaction #K bytes	Bytes	MK
9 + (K - 1)	Generator’s public key	Bytes	32
10 + (K - 1)	Block’s signature	Bytes	64

Generation signature is calculated based on the hash (Blake2b256) of the following fields:

Field order number	Field	Type	Field size in bytes
1	Previous block’s generation signature	Bytes	32
2	Generator’s public key	Bytes	32

The block signature is calculated based on the following data:

Field order number	Field	Type	Field size in bytes
1	Version (0x02 for Genesis block,, 0x03 for common block)	Byte	1
2	Timestamp	Long	8
3	Parent block signature	Bytes	64
4	Consensus block length (always 40 bytes)	Int	4
5	Base target	Long	8
6	Generation signature*	Bytes	32
7	Transactions block length (N)	Int	4
8	Transaction #1 bytes	Bytes	M1
…	…	…	…
8 + (K - 1)	Transaction #K bytes	Bytes	MK
9 + (K - 1)	Generator’s public key	Bytes	32
