A survey on the current situation of family education for primary school students points out that half of parents only use learning as the main content of parent-child communication, while parent-child communication, children generally reflect that not only the content of communication is not pleasing, the method also has problems.
In parent-child relationships, they are always more meticulous and lost than others. For example, if a child does something wrong, they will record the process. Then step in and think about ways to solve the problem.
o?child node, a list (path suffix, hash code for child BMJT node) pair, so that the path of each child node is the path of the parent node and the corresponding path suffix connection. No two path suffixes can share the same first element.
As mentioned earlier, OP_RETURN data from the data is TXhash of its parent node, which is the data from which it can be found by whom. Although this data is written on the child node, but can not be dedested, without the permissions of the parent node, the resulting child node is illegal, then how to determine whether the child node is really generated by the legitimate parent node, this will be used in Bitcoin's own public key system. The child node is labeled with the hash of the parent node, and the metanet transaction of the parent node can be found through hash, the parent node transaction must have the public key (Pparent) that the parent node is used to prove its identity, and metanet requires that the child node be considered to be produced only if the input of the child node has the public key and signature of the parent node. In other words, only the parent node has the right to produce child nodes, which is guaranteed by Bitcoin's signature system. This is also in input in the image above.

Popular wallet developer Electrum has released an emergency patch for a key vulnerability in Bitcoin wallets.
The main reason for the Trezor vulnerability is that it does not have built-in multi-signature functionality, so its multi-signature implementation is to support Electrum extension. This led to an attack on electrum, and Trezor was affected.
Like Bitcoin's core wallet, Electrum Wallet allows users to control their own funds and private keys. Electrum wallets' private keys can also be exported and used on other supported wallets to access funds. Electrum apps are available for Windows, Linux, OSX and Android, but do not support iOS and browser clients.
A botnet with more than 140,000 machines has launched a DoS attack on the server of Bitcoin wallet Electrum in an attempt to direct users to counterfeit software that steals bitcoins. Security researchers say that if a user installs a fake version of Electrum, all funds contained in the fake version will be lost immediately.
The problem was not fixed. So he had to contact Electrum to highlight the urgency of the issue, and Electrum released Emergency Response Version 3.0.4 a few hours later.Tags: electrum won't open

Because the front end often attaches and rewrites HTTP request headers, such as X-Forwarded-Host and X-Forwarded-For, as well as many custom headers with names that are often difficult to guess. Our smuggling requests may be missing these headers, which can lead to unexpected application behavior and failed attacks.
