Post 95 blockchain boom
blockchain technology has the following four ways to make money:
1. Hardware and infrastructure. A typical one is mining machinery proction and distribution chain, where you can make money by buying mining machinery and digging
2. The underlying platform of blockchain and common technologies, such as Ethereum and other public chains, and the privacy protocol nucypher, where you can make money by investing in its token, building applications on the chain, and providing services for users
3. Various vertical applications, such as supply chain traceability and Finance Based on blockchain, right confirmation and trading, can be used or invested to make money
Service facilities, such as digital asset exchange and wallet, media procts, etc., you can make money by making your own exchange

extended data:
type of blockchain
1. Public blockchain
refers to: any indivial or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, Anyone can participate in its consensus process
public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain, and there is only one corresponding blockchain in the world
2. Consortium block chains: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction
3. Private blockchain
private blockchain: it only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and only enjoys the write permission of the blockchain. This chain is not very different from other distributed storage schemes
generally speaking, bitcoin and cryptocurrency tokens provide you with more control. You effectively cut the middleman between you and your money. No bank can decide how long a transaction will take and how much it will cost. You can also control where funds are stored and how they are accessed. Of course, control brings corresponding responsibilities
2. Affordability
since the middleman is not in the picture, you can save some transfer fees. Moving bitcoin from one wallet to another costs a negligible amount of money. It is cheaper for businesses to accept bitcoin payment than credit card payment
3. Speed
in addition to saving international transfer fees, you can also enjoy higher transaction speed. What does it take your bank a few days to do? Bitcoin can do it in a few minutes
4. Convenient
with bitcoin, online payment is easier and faster. If you want to donate or pay for something that will not be delivered, you do not need to disclose any personal details. Just send bitcoin to their wallet address
5. Security
it is safer for businesses to accept bitcoin than fiat money. When businesses accept credit card payments, they risk fraud and reverse payments. Bitcoin payment is irreversible, so there is no risk of reversal
6. Privacy
one of the main advantages of using bitcoin is that it provides privacy and relative anonymity. You don't need to provide any personal details to access the bitcoin wallet. All you need is a device to store it - even a piece of paper. Bitcoin transactions are only linked to your wallet address
7. Reliability
bitcoin network is essentially a point-to-point payment system. This allows you and you to remit money to anyone who participates in the party. You don't have to rely on the bank to do the work to make the transaction effective. In Ethernet, the risk of payment loss is small, which eventually makes it a more reliable way of payment
8. Investing in
bitcoin wasn't worth a lot of money ten years ago. Let's see where it has been since 2009. From a few dollars in December 2017 to nearly $20000. At the time of writing, it is now stable at around $6000. As more and more people adopt bitcoin, bitcoin will not be everywhere. Investing in it may be risky, but it's absolutely profitable.
first of all, blockchain is a kind of chain data structure that connects data blocks in sequence according to the time sequence, and it is a kind of tamper free and forgery free distributed ledger guaranteed by cryptography
secondly, the concept of blockchain is brought out through bitcoin. It is a kind of technology. How can technology be realized? It must be combined with practical applications in life and create practical value before it can be used to make money
so the best way to do something we don't know about is not to touch it.
