How much is the service charge of off chain transfer out of Red
first of all, we should understand that this service charge is given to miners to encourage them to continue mining and provide enough computing power for bitcoin, so as to ensure the security of bitcoin network. At present, the main income of miners is to get BTC reward by creating new blocks, but the reward is halved every four years. As time goes on, bitcoin transaction fee will graally replace bitcoin reward
under what circumstances should the handling charge be paid? What's the amount
bitcoin system has a series of network rules, including the handling charge rules, which are "what the client should do". When you use bitcoin client (wallet, bitcoin QT) to send bitcoin, the whole process is roughly divided into the following steps:
1. Prepare the bitcoin you want to send
the client is responsible for collecting the balance of bitcoin in your wallet (bitcoin QT) to prepare for payment, Because every bitcoin you receive is in your wallet until you spend it
if you withdraw 3btc and 2btc twice in okcoin bitcoin, their records in your wallet are independent, that is, a 3btc and a 2btc, instead of merging them into 5btc (the wallet only records transaction details, but does not merge the balance, but you can see the total balance on the interface of the wallet), As time goes on, you will accumulate a lot of bitcoin in your wallet. It is conceivable that there should be thousands of such records in okcoin bitcoin wallet. So when you send bitcoin, the wallet must decide which of the above records are most suitable for this sending
the bitcoin you get in a transaction is called "inputs" and the bitcoin you spend is called "outputs". There are multiple inputs and outputs in your wallet
2. Prevent a large number of micro payments from impacting the network
if you recharge the okcoin bitcoin trading platform less than 0.01btc (including the fund changes inside your wallet), you must pay a handling charge of 0.0001. When preparing your payment amount, the wallet has an established rule, that is, when preparing the payment amount in many inputs, try to avoid the amount change less than 0.01btc (for example, if you want to recharge 5.005btc to okcoin bitcoin, the wallet should choose 3 + 2.005 or 1 + 1 + 3.005 instead of 5 + 0.005)
3. The larger the amount, the higher the age of the currency, the higher the priority
if the amount you send is too small or your bitcoin has just been mined, then your transfer is no longer free. Each transaction will be assigned a priority, which is determined by the degree of currency, the number of bytes and the number of transactions. Specifically, for each input, the client will first multiply the number of bitcoins by the time they exist in the block (currency age, age), and then divide all the procts by the size of the transaction (in bytes). The calculation formula is: priority = sum (input)_ value_ in_ base_ units * input_ age)/size_ in_ If the calculation result is less than 0.576, then the transaction must pay the handling fee. This is why you need to add a 0.0001 when you withdraw with okcoin bitcoin, because the bitcoin transfer in okcoin wallet is frequent, and the time of bitcoin in the block is relatively short, so you need to pay a handling charge. If you do have a large number of small inputs, such as small miners, and want to transfer them out for free, you can add a large amount of bitcoin with a large currency age, and the average priority will be increased, so that bitcoin can be transferred out for free
4. Charge per kilobyte
at the end of the transfer, the client calculates the size of the transfer (in bytes), which generally depends on the amount of input and output. The calculation formula is as follows: 148 × Input amount + 34 × Output amount + 10. If the size of the transfer exceeds 10000 bytes, but the priority meets the free standard, you can still enjoy the free transfer, otherwise you need to pay the handling charge. The cost per 1000 bytes is 0.0001btc by default, but you can also add it in the client by opening the tab "settings & gt; Options & gt; The main purpose is to adjust the handling charge. If the service charge you are setting is less than 0.0001, BTC is calculated as 0.0001. When this rule applies, it will replace the rule in step 2 instead of accumulating.
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".
XTT (Xin time token), based on Ethereum erc20 platform, is a decentralized digital currency carrier based on blockchain as payment technology
Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized Ethernet virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)
the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014
extended data:
background
bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years
the blockchain of bitcoin is actually a set of distributed database. If a symbol bitcoin is added into it and a set of protocol is specified, the symbol can be transferred safely on the database without trusting a third party. The combination of these features perfectly constructs a currency transmission system bitcoin network
however, bitcoin is not perfect, and the scalability of the protocol is a deficiency. For example, there is only one symbol in the bitcoin Network - bitcoin, and users can't customize other symbols. These symbols can represent the company's stocks or debt certificates, which will lose some functions
In addition, a stack based scripting language is used in bitcoin protocol. Although this language has some flexibility to realize functions such as multi signature, it is not enough to build more advanced applications, such as decentralized exchanges. Ethereum is designed to solve the problem of insufficient scalability of bitcoinreference source: network Ethereum
