Bitcoin Cash (BCH) cryptocurrency, which can be used on the Internet or converted to your local money.
BMP link contains the following hash (SHA-256): 535947de7669b7e17b6ceb99dc9bae22a8d076c99ae86fa8d920cd51966cb631
Corresponds to this BCH transaction. It contains the following OP_RETURN hex: 9d05000105001f80446f20796f7520737570706f727420746865206e657720636f696e626173652072756c65207468617420726564697265637473203825206f66206d696e696e67207265776172647320746f206120737065636966696320616464726573733f
Now we must find the 5 additional parameters, in order to have the voting complete.
This transaction includes the following OP_RETURN hex: 9d06535947de7669b7e17b6ceb99dc9bae22a8d076c99ae86fa8d920cd51966cb631000154686520737065636966696320616464726573732069733a2070716e7176396c74376535766a7970307738387a66326166306c39326c38727864676e6c787777396a39
The second byte 06 is the action: voting_parameter. Is used for additional metadata associated with the voting.
The next 32 bytes are: 535947de7669b7e17b6ceb99dc9bae22a8d076c99ae86fa8d920cd51966cb631
And it is the hash of the initial transaction of this vote. Both transactions have the same address as input. The same voting author. Thus, voting is defined by multiple TX and at the same time is atomic and immutable.
The next byte 00 is the type of parameter: point. This is a text that is part of the question statement, in the form of numbered points.
The next byte 01 is the point order. Specifies the order in which the numbered points should be presented.
The following bytes is the text of the point. Decoded with hex2bin() is: The specific address is: pqnqv9lt7e5vjyp0w88zf2af0l92l8rxdgnlxww
There are two more parameters of the same type, which you will find here and here.
This transaction includes the following OP_RETURN hex: 9d04535947de7669b7e17b6ceb99dc9bae22a8d076c99ae86fa8d920cd51966cb631010102
The second byte 04 is the action: vote. These are the votes. Valid when included in a block while the vote is open.
The next 32 bytes are the voting hash transaction.
The next byte 01 is the type of vote: one_election. In the future, other elements and concepts can be voted. For example, chat messages.
The next byte 01 is the validity of the voting. 00 means that the voting is not valid, 01 the voting is valid. This allows a parallel and independent vote, on the wording of the voting itself. Independent of the option you have voted.
The next byte 02 is the voted option! 00 is always Neutral. In this case: 01 is Yes and 02 is No.
This is the second vote. And it is processed in the same way.
When the voting is closed, the voting result is computed by adding up the hashpower of each option. The option with the most hashpower is the winner.
In the first vote, the input and output include the same address: bitcoincash:qpjf08mqnw5g2v4y9yta50s3exek3yp6fcwddtteak
The same address in legacy format: 1AAtD721LQekC6ncHbAp4ScKxSwR7fFeYT
It is the author of the vote.
This is a coinbase transaction. It is very special. Only a miner can do this. It is the first transaction of the block. This transaction has no inputs. It receives the fees and the block reward. This is how all Bitcoins originated.
The coinbase transaction includes multiple output addresses. Miners. The address of the first vote, ending in FeYT, is included.
It receives 0.04374541 BCH. The block total output is 6.25150088 BCH.
Then FeYT address has received 0.7% of the reward of that block.
The difficulty of that 653362 block is 359263959306.8658.
Only this number is needed to calculate the hashpower of the block with: Difficulty * 2^32 / 60 = 2571711593090800000 = 2.57 EH/s
This is 2,570,000,000,000,000,000 hashes per second for that block!
Then, if FeYT received 0.7% of the block incentive, proportionally the BMP calculates its hashpower at 18 PH/s. This signaling method, called power_by_value, is by default and it is compatible with all blocks. There are two more sophisticated methods of signaling that I will explain on another article.
The BMP block_window is the last 4032 blocks for hashpower calculation. Then, when the voting was close, it counted the hashpower of each miner, between 652951 close_block - block_window and656983 close_block.
Between these blocks, FeYT participated in the creation of: 653326 and 653435.
The BMP calculates the proportional hashpower and adds it all up. It does the same with the second participant. And since they have voted the same, it totals it, resulting in the 24 TH/s for the No option.
