, the number of positions. For example, if the deposit is 0.1xbt and the leverage is 100 times, the amount affected by the deposit is 10 x BT, and then the weighted purchase price and sale price after the deal are calculated. A bidding commission is a buyer's Commission for a trader at a specified price and quantity. The auction delegate is the seller's sales delegate at the specified price and quantity. Then, the deep weighted purchase price is the price weighting of the deal at the buyer's pri

previous article, one of the little details we skipped was mining rewards. Now, we are ready to refine this detail. Mining rewards, in fact, is a coinbase transaction. When a mining node starts digging a new block, it pulls the deal out of the queue and appends a Coinbase transaction to the front. The Coinbase transaction has only one output, which contains the

Block hashing algorithmBitcoin Mining uses thehashcashproof of work function; The Hashcash algorithm requires the following PARAMETERS:A service string, a nonce, and a counter. In bitcoin the service string was encoded in the block header data structure, and includes a version field, the hash of the Previous block, the root hash of the Merkle tree of all transactions in the block, the current time, and the difficulty. Bitcoin stores the nonce in the Extranonce field which are part of the

In Coinbase transactions, there is no input, so there is no need to sign. The

size is limited to 1MB (a new virtual currency, called Bitcoin cash--bcc, which is currently 8MB), was just born a few days ago. Because the size of the block is limited, the number of transactions that can be accommodated in each block is limited. The current Bitcoin system provides an average of 10 minutes per block, so the way miners work is essentially collecting all the transactions generated online within 10 minutes and then filling in a block. This block is approximately as shown in the
