Bitcoin: How can I tell who mined a certain block? [duplicate]

The deciphering block extracted by the Bitcoin node

As the largest cryptocurrency network in the world, understanding how bitcoin blocks are extracted for anyone interested in blockchain and mining technology. In this article, we will deepen in the determination process from which has extracted a certain block on the Bitcoin blockchain.

Decoded hexagonal value: a simple approach

An ordinary method to identify which has a block implies the analysis of the decoded value hex a
op_return (referral of the output parameter) in the first transaction which created the block. Op_return is a special exit type that allows minors to create personalized transactions without storing the blockchain.

Here’s how it works:

• In each block, there are two types of transactions:
  Normal transactions and
  transactions OP_Turt

  .

• Normal transactions contain the data necessary to create new or active parts, while OP_RTNR transactions have a single objective.

• When a minor creates a new block, select an NP (new price) which can be used to extract new or active parts.

• The first transaction in the new block is called
  Pré-Mineur transaction , which contains NP and other necessary data.

Decoding of transactions op_return

To analyze the transactions OP_Preturn, you must decode the value of the hexagon of each output address:

• Open a Bitcoin client or use an online tool that accepts the decoding of hexadecimal values.

• Search for the first transaction in the new block (generally the transaction
  pre-minor ) and identify the output addresses.

• Analyze the hexagonal values ​​of these addresses to determine which belong to the transactions OP_RETT.

Identification which extracted a block

To find out who has extracted the block, you must consider more factors:

• Block header : Check the “Merkle Root” hash for the block header to identify potential mining candidates.

• The number of transactions and hashs : Look at the number of transactions in the new block and their hashs (i.e. hexagonal values).

• Hash Power distribution: Analyze the distribution of hash power on different nodes, because it can indicate who has the necessary calculation resources for me.

Conclusion

The deciphering Bitcoin blocks implies the analysis of the OP_return transactions and the understanding of the role of the blocks, the number of transactions and the energy distributions of the hash. Given these factors, you can determine who has extracted a certain block on the Bitcoin blockchain. Although this method is not unexpected, it offers a good starting point for anyone interested in knowing more about Bitcoin exploitation.
