Neo Blockchain Toolkit
The Blockchain is a data structure. The block is composed of block header and block body. As each block has a crpytographic hash of the previous block, a timestamp, and transaction data generally represented as a merkle tree root hash , a chain structure is formed. The block header contains the basic information of a block and provide verification of a block.
The first 10 attributes of the block constitute the header. Block hash and index can be used to identify a block. The hash value is obtained by concatenating the first seven attributes of the block header and performing SHA operation twice. Normally, NEO has only one chain, and each block will be added to the blockchain after it is confirmed by more than two-thirds of all the consensus nodes. Therefore, the height of the each block is unique. From Wikipedia, the free encyclopedia.

Great talking at Geneva Blockchain Annual Congress with more than industry participants! NextConsensus is a hash of multi-signature contract, which needs more than two-thirds of the signatures of all the consensus nodes as parameters. The example script is as below. Each block, with the NextConsensus field, locks the nodes participating in the next round of consensus activity.
In the previous round of consensus activity, the Speaker calculated the consensus nodes of the next round based on the voting at that time, generated the multi-signature contract, and assigned the hash value of the contract to the block's NextConsensus field. Witness is the verification script of the block, it contains InvocationScript and VerificationScript. The InvocationScript provides the parameters for the VerificationScript to execute. The block body is a transaction list.
In one round of consensus activity, the Speaker selects all the transactions in the memory pool, have them sorted and filtered by plugins, and then package them into a new proposal block. For more details about consensus, please read "Consensus Mechanism" section. The first transaction of each block must be a MinerTransaction , which is used to record all transaction's network fee in the block.
At present, a block can hold up to transactions in total, including up to 20 free transactions and a MinerTransaction as the first transaction in the block. When a block is persisted, it stores a hash list of transactions that belong to the block. And the transaction data is stored separately to facilitate query.
