BTC full block data backup

Publish: 2021-05-06 00:20:51
1. Can be transferred to other disk, or even transferred to the mobile hard disk, portable

with the increasing capacity of bitcoin blockchain data, the client wallet data is installed on Disk C by default. If Disk C is not large enough, you need to find a way to move the data from disk C to other disks
examples are as follows: (Note: close the client first)
1. Find bitcoin's data folder:
XP --- C: & # 92; Documents and Settings\ username\ Application Data\ Bitcoin
vista,win7---C:\ Users\ username\ AppData\ Roaming\ Bitcoin
2. Copy this bitcoin folder to other disk with large space, such as disk D (to avoid operation error, it is recommended to it first and delete disk C after it runs normally, so as to save disk C space)
3. Edit the bitcoin shortcut on the desktop (if there is no shortcut on the desktop, there are two ways: one is to find the installation folder, find "bitcoin QT. Exe", right-click, and select Create Shortcut to cut the shortcut to the desktop or any location; For the second method, if it is a green installation free version, you can find this installation folder, find "bitcoin-qt.exe", right-click and select Create Shortcut to cut the shortcut to the desktop or anywhere.) Right click on the shortcut, select "properties", enter the following in the "target" column and confirm:

& quot; C:\ Program Files\ Bitcoin\ bitcoin-qt.exe" - datadir=D:\ Bitcoin
(red is the target location of the added part)

now, double-click the bitcoin shortcut on the desktop, the client will start, and all data updates will be stored in disk D, and disk C will no longer occupy space. This method can also avoid data re download caused by deleting Disk C e to system re installation, and can also protect wallet files.

Blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block


the data on bitcoin blockchain, which we call the data on the chain, generally includes: bitcoin active address, new address, continuous active address, reactivated address, transaction volume on the chain, number of transactions on the chain, TSP, transaction transfer fee on the chain, large amount transfer, mining difficulty and other data



we generally query the data on some blockchains through the blockchain browser, Bitcoin's more commonly used blockchain browsers are:

    3. Bitcoin blockchain is a bitcoin blockchain? No, the block stores the transaction. In the early stage, you will get a coin if you successfully build a block. In the later stage, you can only get the fees paid by the exchange. A currency is a string of digital signatures. It is a digital signature sent by the last owner to the receiver. Everyone can see who owns the currency from the transaction
    does each node have complete blockchain data? You mean a user node? A user node needs to keep the of the block head of the longest workload proof chain, so it knows the data of all the block heads. It can move forward to know all the data on the block chain, but not all of them are saved. A block header is very small, only 80 bytes, which can be saved completely, because the generation of nodes is very slow. Even with the passage of time, the amount is not too large now.

    blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology

    extended data:

    disadvantages of blockchain technology applied to digital currency:

    first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology

    Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods

    Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements

    Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btc

    5. How to mine every day; Share mining tips every day; When the initial physical strength is tight, when it is close to 20 times, you can leave two small monsters without fighting. For example, when the number of monsters reaches 18, you can leave two small monsters, and then dig long-time gems to save your strength. When the physical strength is close to the upper limit, you can kill the two small monsters and start looking for the big boss. This can avoid that you can't find the big boss if you don't have enough medicine. Because mining is mainly for the soul crystal and the golden man, the little monster will appear in your field of vision, and the little golden man will appear in your field of vision + 1, so the larger the field of vision you open, the greater the chance of the appearance of the little monster and the little golden man. The same physical strength, in order to open a larger field of vision, the following mining method is recommended. First, one line is g to the bottom. At present, the deepest mining area is 302, which can be g to about 270. Then, four lines are opened horizontally, which are A copper tin Ruby line, about 30 deep A line of iron violet, about 65 deep Silver Emerald is a line, and other gem ores are a line at 270 depth It doesn't matter about the left and right sides. You need to dig horizontally and don't dig back. You can adjust up and down if you need minerals or rocks that need explosives. This can ensure the maximum range of vision under the same physical strength. When you need certain resources, you can dig along a certain line. In addition, if the field of vision is large, more pink gemstones such as pink diamonds will be proced, which can improve the mining efficiency. It is suggested that novices can open a miner card after digging to the depth of 270. For nothing else, the efficiency of double line mining can be improved a lot. There is no need to upgrade the types of automatic mining, because it does not improve the efficiency of mining. If there is a shortage of ore, you can buy more miners. You must order titanium Titan steel before going to bed every day. Automatic miners are the same as mining areas. Although they can't be used at present, they can't be used in the later stage. Keep at least 4 or 5 explosives, otherwise sometimes you will cry when you meet the little golden man surrounded by stones.

    1. During the first phase of the interstellar war, players only need to place the hang up location in the first and second levels of each map, and they will get a crystal ore as well as props. Because the first and second levels can get props once an hour, So players can get 24 crystal ores in one day, and 24 * 7168 crystal ores in seven days

    2. During the activity period, players only need to open any treasure box in the mining area to a certain extent to get the crystal ore reward, which is divided into five grades

    3. Electronic competition Wallet: ring the activity period, you can get rewards when you recharge to a certain amount, among which you can get crystal ore bag when you recharge more than 30 yuan, and you can get 100 crystal ore when you open the crystal ore bag

    accumulatively support 50 crystal ores to obtain: honor fragment * 1000, detonator * 5, troll statue * 5, mysterious stone * 1

    7. Unified energy systems (UES), the world's largest power supply company,

    8. Can be transferred to other disk, or even transferred to the mobile hard disk, portable. With the increasing capacity of bitcoin blockchain data, the client wallet data is installed on Disk C by default. If Disk C is not large enough, you need to find a way to move the data from disk C to other disks.

    Bitcoin core wallet is the most complete and secure wallet on the market, and it is also the earliest bitcoin client. However, e to the huge volume of blockchain data file (blockchain) that needs to be loaded in the proct and slow startup, it will be troublesome for novices to start

    bitcoin wallet

    a wallet usually has multiple private keys, and many bitcoin investors also have multiple wallets. Wallets can be placed on computers and / or mobile devices, on physical storage devices, or even on paper

    e-wallet - e-wallet can be downloaded software or hosted in the cloud. The former is just a format file that exists on your computer or device to facilitate transactions. Hosted (cloud based) wallets usually have a more user-friendly interface, but you will trust a third party with a private key

    software Wallet - installing a wallet directly on your computer can provide you with the security of your control key. Most have relatively simple configurations and are free. The disadvantage is that they do require more maintenance in the form of backup. If your computer is stolen or damaged, and your private key is not stored elsewhere, you will lose bitcoin

    Mobile Wallet - mobile wallet can be used as an application for smart phones, especially if you want to pay with bitcoin in the store or buy and sell on the road. All of the online wallets mentioned above and most of the desktop wallets have mobile versions, while others (such as Abra, airbitz and bread) are created with mobility in mind

    Hardware wallets - hardware wallets are small devices that are sometimes connected to the network for bitcoin transactions. They are very secure because they are usually offline and therefore cannot be hacked. However, they may be stolen or lost along with bitcoin belonging to the stored private key. Some large investors keep their hardware wallets in secure locations, such as bank vaults. Trezor, keepkey and ledger and the case are obvious examples

    paper wallets - perhaps the simplest of all wallets, these are all paper with the private key and public key of the bitcoin address printed on it. These wallets are ideal for long-term storage (obviously, away from fire and water) or as a gift of bitcoin, because they are not connected to the network, so they are more secure. However, they are more likely to be lost

    with services like walletgenerator, you can easily create new addresses and print your wallet on the printer. Fold, seal, and you're done. Send some bitcoin to the address and store or distribute it safely
