1. How to operate the isolation witness? In fact, it's not so simple ~
isolation witness is a method of blockchain expansion, which has been successfully implemented on lightcoin and bitcoin
at present, each block in the blockchain not only records the specific information of each transfer transaction, that is, at which time point the account receives or transfers out how many bitcoins, but also contains the digital signature of each transaction, which is used to verify the legitimacy of the transaction. The miner needs to verify each transaction one by one with digital signature when packing the block. After confirming that there is no problem, the transaction will be recorded in the block
however, for ordinary users, they only care about the number of assets in each account, and do not need to verify each transaction one by one. Isolation witness is to take out the digital signature information in the block, so that each block can carry more transactions, so as to achieve the purpose of expansion.

2. Bitcoin isolation verification simply means that there is an additional side chain. The main chain and the side chain complement and support each other. Isolation verification is to solve the problem of bitcoin congestion. At the end of 2013, the problem of bitcoin congestion has appeared, and the expansion has become the consensus of the community, but there is no consensus on how to expand
in 2016, the community held a meeting in Hong Kong on capacity expansion. At the meeting, China's absenteeism and bitcoin core reached a consensus and proposed a compromise scheme, namely hard fork and isolation certification. This is the result of compromise between the two sides, but later the core went back on its words and forced absenteeism to accept the isolation scheme, but did not expand the capacity. China mostly opposes the exclusion of isolation verification.

3. The malleability of trading, also known as malleability, is the same thing (such as a lump of metal). Its essence and quality have not changed, but its shape has changed. This malleability will cause the inconsistency between transaction ID and txid, so that the user can't find the sent transaction
in the transaction data format of bitcoin, the transaction signature part is also included in the overall transaction. Finally, the overall transaction is hashed, and the transaction signature can be written in a variety of ways. If the attacker tampers with them, their functions are the same, but the byte has changed, resulting in a different signature, Some time ago, there was even a mine pool g out, which contained all the transactions that were extended attacks, bringing trouble to some applications
the change of txid may cause some applications can not find the txid when searching for it, thus affecting the status of some wallets' recharge or withdrawal, and bringing trouble to operators and users. Isolation witness is proposed to solve this problem. The transaction data and signature data are separated, so the txid of a transaction must be unique.

4. I am also a victim of this platform
fortunately, I have solved the problem of letting back the principal. How dangerous! I've been cheated by more than 100000 people, and my problem has been solved.

5. They won't sue you. It's OK. Once there is a large loss, people will call the police, and you will be miserable
6. If there is a legal will, it should be done according to the will. If there is no will, it should be done according to the legal succession procere. It is necessary to explain the specific situation of your family, who is the registered house, and the specific situation of the heir
7. Not for the time being
8. Capacity expansion is a means that when a container or load is not enough to support or carry the demand of existing things, we can expand the capacity of the container or load to meet the growing demand, so as to relieve the pressure on the current container or load
at the beginning of the birth of bitcoin, Ben Cong, the founder of bitcoin, did not deliberately limit the block size. The maximum block size was 32MB, and the average block size was 1-2kb at that time
at that time, there are few bitcoin users and the transaction volume is not so large, which will not cause block congestion. However, since 2013, with the price of bitcoin rising sharply, there are more and more users, resulting in network congestion of bitcoin and rising transaction costs of users
up to now, there is a backlog of hundreds of thousands of transactions on the bitcoin blockchain. The average transaction cost of bitcoin is 376 times higher than that in September 2010. The processing speed of seven transactions per second has obviously been unable to meet the needs of users. The bitcoin community has begun to explore how to "expand the capacity" of bitcoin
by modifying the underlying code of bitcoin, the transaction processing capacity can be improved
there are two development and design schemes for bitcoin expansion, namely, the first layer and the second layer expansion technology
· the first layer of capacity expansion technology is to improve the blockchain itself, to make the blockchain itself faster and larger. Generally speaking, it is to change the content of the consensus part of the blockchain
· the purpose of the second layer expansion technology is to move the computing to the lower chain, that is, to solve the problem through the side chain technology
expansion protocol and outcome
expansion protocol generally needs the support of miners, which can be roughly divided into modifying block size, soft fork, hard fork, isolation witness and so on
take bitcoin as an example:
bitcoin is now divided into big block bitcoin cash (BCH) and isolation witness. Isolated witness is now recognized as bitcoin in the market, while big block coin is named bitcash. It can be predicted that in the future, bitcoin will focus on off chain trading. Including lightning network and side chain. These two new things are not mature at present, but they are highly expected by many people
bitcoin will develop a large number of isolated witness transactions and make more derivative technologies on the basis of isolated witness. Most likely, bitcoin will be pushed forward by technology
bitcash will focus on the development of monetary function, rece transaction friction as the main way, and gain more extensive users on the chain as the main development direction
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China.
