Bitcoin client capacity solution

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.

2. If you want to contribute to the bitcoin network, it's a good choice to run a full node to synchronize the block data; If you just want to use bitcoin, you don't need a full node wallet at all. You just need to install a new wallet. The better one in China is the coin pack.

3. Slicing technology is one of the common methods used by developers to improve transaction throughput
in short, slicing is a partition method to divide computing power and storage workload in a point-to-point network. After slicing, each node no longer needs to deal with the transaction load of the whole network, It only needs to process the transactions in the partition (or partition)
just like the current blockchain, the information contained in the partition is jointly maintained by multiple nodes, thus ensuring the decentralization and security of the ledger. After the partition is enabled, everyone can still see all the information in the ledger, but people no longer need to process and store all the information

4. At present, the data capacity of bitcoin blockchain continues to grow. Now it's about 10g. When many friends install the system, Disk C is not set very large. Are you worried that disk C will explode one day. Now learn how to do data migration with me First, close bitcoin client)

1. Find bitcoin's data folder< br />
XP---C:\ Documents and Settings\ username\ Application Data\ Bitcoin

vista,win7---C:\ Users\ username\ AppData\ Roaming\ Bitcoin
(Note: appdata is hidden, set to show hidden files.)

2. Cut this bitcoin folder to other drives with large space, such as disk E

3. Edit the bitcoin shortcut on the desktop, the following line to the "target" column, and then save it:

& quot; C:\ Program Files\ Bitcoin\ bitcoin-qt.exe" - datadir=e:\ Bitcoin

now, double-click the bitcoin shortcut on the desktop, the client will start, and your C disk will be saved, releasing space successfully.

5. This is a drawback of bitcoin. You can't delete it. You have to resynchronize after deleting it. Of course, you can use light wallet, but its security is not as good as this one

6. I think this is the biggest problem of BTC at present. The current transaction volume is still very small. If the transaction volume increases by 100 times, the client data will become a headache, that is, the transaction volume does not rise. If the wallet keeps rising and reaches the P level, synchronization will become impossible. The designer of BTC has considered this problem, but it's a pity that the problem has not been solved after he left.

7. Only full node clients like bitcoin core need longer synchronization time. Technically, synchronization is a process of downloading and verifying all previous bitcoin transactions on the network. Some bitcoin clients need to know all previous transactions to calculate the available balance of your bitcoin wallet and complete new transactions. This step consumes a lot of resources and needs enough bandwidth and space to store the whole block chain. In order to maintain the security of bitcoin, enough users need to use the full node client, because they play the role of confirmation and relay transactions
an error has occurred, which may be e to network disconnection or incompatibility. Just update it. As a matter of fact, the online money and packet technology has developed quite mature now. It's better to put bitcoin in your own computer than in your online wallet. Of course, if you are a technology flow, you can go anywhere.

Use the software move tool in QQ computer manager to move the bitcoin client cache folder under Disk C to a large disk, or to a mobile hard disk, so that you can use it anywhere at any time

9. The birth of trusted computing, is to protect data privacy through a variety of cryptography technology, at the same time, make data to large-scale application. TCP proposed in this paper is a kind of privacy protection computing scheme based on blockchain technology and combining offline computing and tee. This scheme enables enterprises and indivials to deploy the data processing model on the blockchain, process the privacy data in the trusted execution environment under the blockchain, and finally store the verifiable results on the chain and update the status. The whole process ensures the privacy and security of the data by means of cryptography and tee.
