In terms of online advertising, CPA, CPC, cpm, CPO, PPC, PPL, cptm, and other abbreviations are frequently encountered. These are abbreviations of online advertising pricing methods, the following is an explanation of these concepts in Chapter 6th of network marketing basics and practices.
A group of frequently used terms on the online advertising pricing model:

Common Terms for network advertisement billing methods:Terms highlighted: CPA CPL, CPC, cpm, and CPS"1. CPA (cost-per-Action): the cost of each action, that is, the pricing model based on the actions each visitor takes on online advertising. There are special definitions of user actions, including forming a transaction, obtaining a registered user, or clicking on an online advertisement.Cpl (cost for per lead): pay commission based on successful regi
Any online advertising system, are faced with the problem of ROI, for Invest, we do not consider, because there are many ways for traffic can be bought back, also can not be optimized (of course, when RTB is optimized). Return is the main optimization direction,return= Ctr * Value created per click. For example: click-through rate is 10%, each Click brings the benefit is 5 yuan, then the profit of each hit is 10% * 5 = 0.5 Yuan.There are two very important concepts in the calculation of advertis
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

As shown in the figure, the process of signing and verifying the data is as follows:
Now to review the complete lifecycle of a transaction: At first, the Genesis block contained a Coinbase transaction. 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
