Ethereum private key 2 can be stolen

1. 1. What is the ether classic<

etc (Ethereum Classic) is a bifurcated currency that Ethereum hard bifurcates after 1920000 blocks, and its function is very similar to Ethereum. Etc adheres to the concept of decentralization and supports the consensus mechanism of blockchain guarantee. Etc firmly believes that once the blockchain starts to run, its development direction will not be controlled by any central team, but will be determined by the consensus of the people participating in the whole network and the consensus of the computing power of the whole network

the Ethereum blockchain hard branching in July 2016 aims to transfer the Dao funds stolen by hackers to an account controlled by investors, and let the old transaction records be forgotten by history. Most Ethereum developers are involved in the reversal, as are exchanges, startups and other members of the ecosystem. A few days later, the project returned to normal. But not everyone wants to forget the old record. As a result, a small number of miners continued to use the original blockchain as a protest. They described the hard fork as a capital withdrawal for the abandoned project of the Dao. So Ethereum classic (etc) was born

main features: independent cryptocurrency

2. Ethereum is a distributed computing platform. It generates an cryptocurrency called ether. Programmers can write "smart contracts" on the Ethereum blockchain, and these Ethereum smart contracts will be executed automatically according to the code

what is Ethereum
Ethereum is often compared with bitcoin, but the situation is different. Bitcoin is a kind of cryptocurrency and distributed payment network, which allows bitcoin to be transferred between users

related: what is bitcoin? How does it work

Ethereum has a bigger goal. As Ethereum says, "Ethereum is a distributed platform running smart contracts.". These smart contracts run on "Ethereum virtual machine", a distributed computing network composed of all devices running Ethernet nodes

"distributed platform" means that anyone can set up and run an Ethereum node just as anyone can run a bitcoin node. Anyone who wants to run "smart contracts" on nodes must pay the operators of these nodes in ether, which is a cryptocurrency related to Ethereum. Therefore, the person running the Ethernet node provides computing power and gets paid in the Ethernet, which is similar to the way that the person running the bitcoin node provides hash power and pays in bitcoin

in other words, although bitcoin is only a blockchain and payment network, Ethereum is a distributed computing network, and its blockchain can be used for many other things. Details are provided in the Ethereum white paper

what is ether
Ethernet is a digital token (or cryptocurrency) related to Ethereum blockchain. In other words, Ethereum is the token and Ethereum is the platform. But now people often use these terms alternately. For example, coinbase allows you to buy Ethereum, which stands for Ethereum

this is technically "altcoin", which actually means a non bitcoin cryptocurrency. Like bitcoin, ether is supported by distributed blockchain - in this case, Ethereum blockchain

developers who want to create applications or Ethereum smart contracts on Ethereum blockchain need Ethernet token to pay for nodes to host it, while users of Ethereum based applications may need Ethernet to pay for services in these applications. People can also sell services outside the Ethereum network and accept Ethernet payments, or they can sell Ethernet tokens in cash - just like bitcoin

3. If it's lost, it's better to post the lost advertisement

4. At present, there are many digital currency wallets, some of which have good personal experience

light wallets are good for imtoken, geekwallet, kcash, Cobo, etc.

5. Confinement is a thing that must be done after childbirth. If you don't take delivery, the maternal body will leave the root of the disease after pregnancy, which is difficult to cure. Pregnant women can choose to take delivery at home or in the delivery center

first of all, confinement is usually for one month. So whether at home or in the confinement center is the same, it needs to live for a month. But this time is not certain, can only be said to be at least a month's time to live. A month is a minimum time, even if the maternal recovery is fast, but also to live enough for a month. But if the maternal recovery is relatively slow, then it is not only to live for a month, it is necessary to live longer. Therefore, it is more recommended that pregnant women take delivery at home, which is more convenient and comfortable<

secondly, confinement is the key period for a newborn baby to recover. During this period, it is necessary to take good care of the baby. The time of each confinement is different, but it is generally 30 days or 42 days, so the body will recover more completely

in the end, the place to take delivery of the baby must choose a better place, a place with more complete facilities and better service. Otherwise, if the pregnant woman goes to the delivery center and no one is in charge, the delivery of the baby will be greatly reced

pay attention to diet after childbirth:

women have higher requirements for diet when they are in confinement, and many women think that there are not so many restrictions after childbirth, but as long as women are still in lactation, there are still many things to pay attention to

During lactation, women should not eat food with milk returning function, such as leek, malt, etc. Many women think ginseng tonic body is very effective, but ginseng will make maternal milk, in breast-feeding, it is best not to eat. In addition, more estrogen content of food is also easy to cause milk, such as pigeons, hens and so on

2. Women should not eat caffeinated food ring lactation. Caffeine can stimulate the nervous system. It is likely to enter the child's body through milk, causing damage to the child's nervous system and heart, and also causing indigestion

3. Eat less salt and monosodium glutamate, too much salt will increase the burden on the kidney. And monosodium glutamate will affect the development of children, eat too much monosodium glutamate will make children appear mental retardation, growth retardation and so on

women should not only pay attention to their diet when they are in confinement, even when they are out of confinement, as long as they are still in the lactation period, they can not do whatever they want in their diet, so as not to have adverse effects on their children.
