blockchain blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and cryptocurrency algorithm. Is a shared distributed ledger in which transactions are permanently recorded through additional blocks
2, block - block
in the bitcoin network, data will be permanently recorded in the form of files, which we call blocks. A block is a set of records for some or all of the latest bitcoin transactions and is not recorded by other previous blocks
3. Node -- a of the ledger operated by the participants of the blockchain network
Decentralization is a phenomenon or structure, which can only appear or exist in a system with many nodes or in a group with many indivials. The influence between nodes will form nonlinear causality through the network5. Consensus mechanism
consensus mechanism is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; For a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the whole network can also reach a consensus
6. POW -- proof of work refers to how much money you get depends on the amount of work you contribute to mining. The better the performance of the computer, the more money you will be given
In POS mode, your "mining" income is directly proportional to your currency age, and has nothing to do with the computing performance of the computer8. Smart contract
smart contract is a kind of computer protocol which aims to spread, verify or execute the contract in an information way. Smart contracts allow trusted transactions without a third party, which are traceable and irreversible
9, time stamp
time stamp refers to the string or encoding information used to identify the recorded time and date. The international standard is ISO 8601
Turing completion refers to the ability of a machine to perform calculations that any other programmable computer can perform DAPP decentralized application is an open source application that runs automatically, stores its data on the blockchain, motivates it in the form of cryptocurrency token, and operates with protocols showing valuable proof Dao, a decentralized autonomous organization, can be regarded as a company that operates without any human intervention and gives all forms of control to a set of unbreakable business rules13. Privatekey - private key
a private key is a string of data that allows you to access a token in a specific wallet. As cryptocurrency, they are hidden except for the owner of the address
14. Publickey -- public key
is paired with private key. The public key can calculate the address of the currency, so it can be used as a certificate to own the address of the currency
15, miner
try to create a block and add it to the computing device or software on the blockchain. In a blockchain network, when a new effective block is created, the system will automatically give the block creator (miner) a certain number of tokens as a reward
16. The mine pool is a fully automatic mining platform, which enables mining machines to contribute their computing power to mine together to create blocks, obtain block rewards, and distribute profits according to the proportion of computing power contribution (that is, mining machines access the mine pool - provide computing power - obtain income)
17, public chain
fully open blockchain, refers to anyone can read, anyone can send transactions and transactions can be effectively confirmed, people all over the world can participate in system maintenance, anyone can read and write data through transactions or mining
18. Private chain
write permission is only for the blockchain of a certain organization or a specific few objects. Read permission can be open to the outside world or restricted to any extent
19, alliance chain
consensus mechanism is a blockchain jointly controlled by several designated institutions
20, side chain
wedged side chains technology, which will realize the transfer of bitcoin and other digital assets between multiple blockchains, which means that users can access the new cryptocurrency system when they use their existing assets
21, cross chain technology
cross chain technology can be understood as a bridge connecting the blockchains, and its main application is to realize atom transaction, asset conversion, information exchange within the blockchain, or solve Oracle problems among the blockchains
22. The hard fork
blockchain has permanent divergence. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually the hard fork will occur
23, soft forking
when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, which will lead to temporary forking
24, hash -- hash value
generally translated as "hash", but also directly transliterated as "hash". In short, it is a function that compresses messages of any length to a message digest of a fixed length
25, main chain
the word "main chain" comes from the main network (, relative to the test network), that is, the officially online and independent blockchain network

has invested in Bond Capital, a Silicon Valley venture capital company such as Slack and Uber, and has recently told investors through e-mail that the rapid spread and impact of the new crown epidemic is similar to that of the 1906 San Francisco earthquake. Bond's most famous partner, Mary & middot; Mary Meeker, a former bank analyst, is known for her annual Internet trends report, which many investors and entrepreneurs use as a touchstone for current and future technology development. She also got & quot; The queen of the Internet; It's a great reputation. The main contents of her report are as follows:
01 the impact and aftermath of the new crown epidemic,
earthquake is like a high-speed zipper, which can tear the earth 138 miles apart in a minute; &mdash & amp; mdash; This was the case with the San Francisco earthquake of 1906. The shock brought by COVID-19's high speed communication / impact is similar to that of — mdash; China's novel coronavirus pneumonia has been diagnosed on 2 million 100 thousand days by the ninety-fourth day since the first report of overseas cases in April 16, 2020, and 145 thousand people died. P>
electronic health record, as the United States continues to promote medical centralization, weaken the status of hospitals and make patients more capable of consumption like this, we believe that many of the emerging trends in medical technology will accelerate this COVID-19. p>
< EM > 05 we will survive the crisis, but life will be different < / EM >
we are optimists and believe that the other side of despair is hope. But the other side won't come too soon. Many experts predict that the other side will come in a few months, not a few years, which is relatively good news. Although hand washing, social distance and self isolation are necessary, we still need to provide personal protective equipment for medical staff. We also need to prepare ventilators, antiviral drugs, vaccines, virus testing, virus tracking and rapid diagnosis capabilities for the next epidemic (and perhaps the next one). We also need large-scale intervention (effective deployment of resources) by the government, enterprises and entrepreneurs, so as to arrive at & lt; The other side & quot;. We all have to come together to make sure that the economy restarts and jobs are restored so that people will be able to work, have enough security, and take care of themselves. As former U.S. Secretary of state and national security adviser Henry Kissinger wrote, & lt; There was no parallel in history. The global epidemic has changed the world structure forever. The world leaders have learned important lessons from the 2008 financial crisis. The current economic crisis is more complicated. The economic contraction brought by COVID-19 is almost unprecedented in speed and scale. The United States must protect citizens from viruses and start an important task at the same time. That is to plan for a new era& rdquo;
