How long does bitcoin transfer take

1. bitcoin transfer fee is a fee paid by traders to miners, which is used to encourage miners to compete for bookkeeping and provide enough computing power for bitcoin, so as to ensure the security of bitcoin network. In some places, it is also called miners' fee
when users initiate a transfer in bitcoin network, they usually need to pay a certain transfer fee to the bookkeeper. The transfer service charge is generally 0.001-0.0015 bitcoins. Due to the limited capacity of the block to hold transaction records, miners will give priority to the transaction with high service charge, so the overpaid service charge can be recorded faster
the existence of bitcoin transaction fees can improve the transfer threshold, effectively prevent the blockchain from being full of junk information, and ensure that the miners still have the motivation to maintain the bitcoin network after bitcoin is g up.

2. In recent years, e to the waste of resources, unstable block output and computing power attack of pow, although POW is recognized as the most widely used and secure consensus mechanism, there is still a great risk of being attacked for the block chain with insufficient computing power in the whole network. More and more consensus mechanisms are proposed to be used in blockchain projects for trial and experiment. Dpos is one of the mainstream consensus mechanisms, and LBTC has adopted this mechanism. Dpos ensures that the voting right is in the hands of the coin holder, so the coin holder will be able to choose whether to pass the motion by voting, so as to determine the development direction of the project. At the same time, it also means that the development direction of the project depends on the hands of the people who care about the project itself, and the power of wisdom will promote the better development of the project. At the same time, the advantages of dpos mechanism are that there is no computing power attack, strictly abide by the time block and save resources
the number of nodes of LBTC is 101. Compared with 21 or 51 nodes, the coin holder can vote for 51 nodes at most once in the wallet of LBTC, which further reces the risk of centralization; LBTC can output blocks stably in 3 seconds, and the block size of 2m ensures that LBTC is 400 times more efficient than bitcoin, and the transaction speed can reach more than 2000 transactions per second; The most important difference between LBTC and other projects is that LBTC's dpos mechanism has the rule of irreversible block. When the number of block agents reaches 90% or more in one round, or when the number of block agents exceeds 70%, the first block in the previous round can be considered as irreversible, so as to prevent bifurcation.

3. When you transfer bitcoin to fire coin, how long it will arrive at the account is decided by the transferor. Generally, it is normal to arrive at the account within one hour and within 24 hours.
4. It's usually a working day
5. Generally, only the payee can return bitcoin after 24 hours. Any bitcoin transaction is irreversible and can only be returned by the payee.

7. [information]
through the information panel, the guardian can see the current image and detailed attribute values of the character
[attribute stone]
- the guardian will drop various types of [attribute stone] when fighting in the game. After using the [attribute stone] in the backpack, you can add the corresponding attributes
★ the guardian can view the attributes currently added through the attribute stone interface
★ the guardian has an upper limit on the attributes obtained through the attribute stone. After reaching the upper limit, he can't continue to improve the attributes by using the attribute stone; When a character raises the upper limit of an attribute, the attribute stone that was previously used after exceeding the upper limit can continue to raise the attribute
★ the upper limit of the attribute stone can be increased by increasing the level of the character and the advanced level of the character
[advanced]
★ level: there are six stages of character advancement, each stage can be upgraded by 5 levels (each level is added with attributes), and each level can also improve the basic attributes of character upgrading
★ function: after upgrading, the attribute promoted by each level will be higher (the growth value of the protagonist will be increased when upgrading)
progress: Advanced requires the consumption of corresponding levels of advanced essence and gold to enhance the progress. Only increase but not decrease), and the progress will return to 0 after advanced to the next level
★ critical hit: it is possible to generate critical hit ring enhancement, and you will get more progress ring critical hit.

8. 1，4 matlab是有帮助文档的，我没有明白你所指的去中心化处理是什么，PCA的结果在数组自己的维度
以下是帮助文档，请仔细阅读
coeff = pca(X) returns the principal component coefficients, also known as loadings, for the n-by-p data matrix X. Rows of X correspond to observations and columns correspond to variables. The coefficient matrix is p-by-p. Each column of coeffcontains coefficients for one principal component, and the columns are in descending order of component variance. By default, pca centers the data and uses the singular value decomposition (SVD) algorithm.
example
coeff = pca(X,Name,Value) returns any of the output arguments in the previous syntaxes using additional options for computation and handling of special data types, specified by one or more Name,Value pair arguments.
For example, you can specify the number of principal components pca returns or an algorithm other than SVD to use.
example
[coeff,score,latent] = pca(___) also returns the principal component scores in score and the principal component variances in latent. You can use any of the input arguments in the previous syntaxes.
Principal component scores are the representations of X in the principal component space. Rows of score correspond to observations, and columns correspond to components.
The principal component variances are the eigenvalues of the covariance matrix of X.
example
[coeff,score,latent,tsquared] = pca(___) also returns the Hotelling's T-squared statistic for each observation in X.
example
[coeff,score,latent,tsquared,explained,mu] = pca(___) also returns explained, the percentage of the total variance explained by each principal component and mu, the estimated mean of each variable in X.
2. PCA 和SVD的不同是，他们分解矩阵的方式是不同的我建议你翻看wikipedia里面SVD和PCA的说明，里面公式很清晰了

9. The answer is quite a few, but not many to the point
the motherboard supports PCIe × 16, the problem is not big, in theory, the mainstream of the lower end graphics card can be used. But considering your weak small power supply, 96gso can be directly ignored. The rating should be more than 230W. The TDP of your original whole system is about 200W. Is the rating 230W? Brand machine in this respect usually (I mean usually ~ ~) will not shrink, the rating should be above 250W. The old 65nm and 55nm cards will not be considered. We recommend the enhanced version x2
of YinChi GT220 http://detail.zol.com.cn/vga/index216225.shtml
tdp60w is not available, so it is affordable and the price is reasonable
the performance is better than 95gt and 4650, slightly inferior to 96gso G94 and HD4670. It's enough for your U. And this kind of low-end small card, the size will not be very big, card body is quite short, HTPC small chassis is no problem, you can absolutely plug in.
