Principle of blockchain cold Wallet
Seeing some answers to the debate on the definition of blockchain, I suddenly realize that my answer to this explanation principle has always been directed at bitcoin. There is no specific and unique answer in the instry between the definition of blockchain. Here I first summarize the characteristics of "blockchain" according to the papers I read:
1; Hash chain & quot There are several nodes participating in the system operation (distributed)
3. Reach a consensus on the consistency of basic data (consensus agreement / algorithm) through a certain protocol or algorithm
since bitcoin is currently one of the most typical and influential applications of blockchain, it will be much easier to understand how bitcoin uses blockchain before understanding other forms of blockchain applications
cold wallet refers to the wallet where the network can't access your private key. Generally, it will take a notebook to record it. Although it avoids the risk of being stolen by hackers, it may also be lost
a hot wallet is a wallet that can access your private key on the Internet. Hot wallets are often in the form of online wallets, which are not easy to lose, but also have risks.
bitcoin wallet can be divided into cold wallet and hot wallet according to the storage method of private key
01. A cold wallet is a wallet that can't access your private key on the Internet
cold wallets often rely on "cold" devices to ensure the security of bitcoin's private key, such as computers that are not connected to the Internet, mobile phones, small notebooks with private key addresses, etc. Cold wallet avoids the risk of hackers stealing the private key, but may face physical security risks, such as computer loss and damage
02. Hot wallet refers to the wallet that can access your private key on the Internet
Hot wallets are often in the form of online wallets. When using hot money package, it is better to set different passwords on different platforms and open secondary authentication to ensure the security of your assets
wallet is actually "a management tool for private key, address and blockchain data".
transactions in bitcoin are completely anonymous. That is to say, no one knows how much money you have and where your wallet is
so even if people want to steal you, they don't know where to put their hands.
the red suit of the blaster hero can be obtained by dropping the level and opening the weapon or equipment box
among them, the higher the difficulty of level, the higher the possibility of obtaining
and the probability of high-grade box is higher than that of ordinary box
at the same time, there is a great probability that red weapons and equipment will be dropped in daily tasks
I hope my answer can help you
When it comes to cold wallets, I think this knowledge is relatively deep, and the latest procts have always been concerned. According to the more authoritative answer of the network, it is like this:
< blockquote >cold wallets refer to bitcoin storage technology developed by information technology companies that provide blockchain digital asset security storage solutions. Cold wallet integrates the functions of digital currency storage, multiple transaction password setting, publishing the latest market and information, providing hard fork solutions, etc., and uses two-dimensional code communication to make the private key never touch the network, which can effectively prevent hackers from stealing
< / blockquote >hardware cold wallet has great advantages
< blockquote >the storage function of hardware cold wallet is similar to that of hard disk, but it needs to pay password when trading, and randomly generate strong seed password to obtain private key and address, and each transaction is digitally signed and commented, which can be checked at any time; The online app can query the latest market and information online, open and transparent information, automatically detect the transaction confirmation, and never touch the private key

The Chinese name of BCC is bitcoin cash. The total number of BCCs is 8400, which is the same as that of bitcoin
bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers
bitcoin cash is a new type of block assets generated by a hard bifurcation of bitcoin. The isolation verification is removed, the block size limit of 1m is removed, and the capacity expansion roadmap of Nakamoto Tsung is continued, which is a kind of capacity expansion on the chain
extended data:
the generation principle of bitcoin:
the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
compared with RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you will have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
completely decentralizing, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
to be exact, it is 2099999.97690000. Bitcoin electronic disk market is still very good
