How to find foreign blockchain mining
In short:
1. bitcoin is a digital currency, and blockchain is a technology
2. Blockchain is the underlying technology of bitcoin, and bitcoin is the first application of blockchain technology; As a state supported and vigorously developed blockchain technology, it will be widely used in all walks of life in the future
3. Blockchain technology is not a new technology, but a new logic of thinking, which just rearranges and combines many previously unrelated algorithm technologies
4. Blockchain means that a block is connected with a block, and thousands of blocks form a chain; To connect the next block, you need to calculate the algorithm answer (mining), and the reward for mining is bitcoin

there is a certificate generation tool makecert.exe in MS sdk6.0. You can use this tool to generate test certificates
in the first step, a self signed root certificate (issuer) is generated< br />> makecert -n " CN=Root" - R - SV rootissuer.pvk rootissuer.cer
at this time, a prompt box will pop up. First, set the private key protection password for the rootissuer.pvk file
then, enter the password again and use the private key (in the rootissuer.pvk file) to encrypt the public key (in the rootissuer.cer file)
the second step is to use this certificate to issue a sub Certificate (subject)< br />> makecert -n " CN=Child" - IV rootissuer.pvk - IC rootissuer.cer - SV childsubject.pvk childsubject.cer
in this case, a prompt box will pop up to set the protection password for the private key file childsubject.pvk of this sub certificate
then, enter the password of the private key (in childsubject. PVK) of the sub certificate to protect the public key of the sub Certificate (in childsubject. CER)
next, you will be prompted to enter the password of the private key of the root certificate (in rootissuer. PVK) to sign the whole sub Certificate (public key and user information)
if you want to issue more sub certificates, similarly, you can use this certificate to issue further certificates, provided that the childsubject certificate can also be used for issuing (as an issuer)
remarks:
(1) if you need an interactive certificate for secure communication, add the option sky exchange
(2) if you need a signing certificate to sign certificates or binary files, then add the option sky signature.
(3) if you need a client certificate to mark your identity or personal information protection (e-mail), then the E field in option - n is indispensable
examples: - N & quot; CN = company name, e = e-mail address, o = organization name, Ou = organization unit, C = country, s = province (state), P = County & quot< Other auxiliary tools:
1) public key certificate format is converted to SPC. cert2spc.exe
> Cert2spc testroot. Cer testroot. SPC
. SPC means software publisher certificate.
2) combines the public key certificate and the private key into a PFX format certificate file. pvk2pfx.exe
> Pvk2pfx - PVK testroot.pvk - SPC testroot.spc - PFX testroot.pfx
enter the protection password of testroot.pvk to merge. PVK and. SPC files. If you do not set the protection password of testroot.pfx to be merged, the protection password is the same as that of the input file testroot.pvk Note: it's OK to get the CER file directly, but it's not necessary to get the SPC file).
3) signature tool. Signature.exe
binary file digital signature. In order to ensure the integrity of binary file, digital signature is a good method
the following command starts a file signing tool wizard with graphical interface:
& gt; Signtool wizard
the following is the command line signature:
& gt; signtool sign /f " Full path of PFX file & quot/ p " Protection password of PFX file & quot/ t " http://timestamp.verisign.com/scripts/timstamp.dll" / d " Description of this signature & quot& quot; The whole path of the signed program & quot;
Can DAPP really make money? The essence of DAPP mining is to pursue the most advanced mining technology; Under the winning rate, the highest is 12068; Mining profits, not gambling. Judging whether you can make money is actually very simple: as long as the value of the game token you get is greater than the mining cost, you can make money
note: mining cost includes CPU rental cost, platform pumping cost, lost EOS, etc. At present, most of the items are 12140; On the day when Fang went online, he would go to China; Huajiao and Zhuo 63968; So, 12157; The miner according to the traffic regulations; The real-time price and mining model decide whether to mine or not. If it is profit, it will be profit; If it is, it will flow into the project to excavate and advance to 12175; It's the same as the previous one;. The simplest mining model is as follows: profit and loss EOS = (mining reward * current &? 64008; In this model, the only variable is the current - { 64008; Other numerical items will be publicized. December 28, Beijing time; 16: Dappdiscovery selected several popular projects as samples and made quantitative analysis based on the current market price
According to the table,
at present, these popular gambling projects are not suitable for mining, that is to say, mining is at a loss
