区块链信息保存多长时间有效,区块链信息保存多长时间失效

近几年，随着区块链技术的发展，区块链信息的保存已经成为一个重要话题。那么，区块链信息保存多长时间有效，多长时间失效呢？

首先，区块链信息的保存时间是受网络硬件和软件等技术环境的影响。一般情况下，区块链信息的保存时间可以达到几十年，甚至几百年。这是因为区块链的信息是通过分布式账本的方式记录的，这种账本可以持久化存储，不会受到网络硬件和软件环境的影响。

其次，区块链信息的保存时间也受到网络安全性的影响。如果网络安全性较低，区块链信息就会暴露在风险之中，容易遭受黑客的攻击，从而导致区块链信息的丢失。因此，要想保证区块链信息的有效保存，就必须确保网络安全性较高。

再次，区块链信息的保存时间也受到网络维护和维护的影响。如果网络维护和维护得不好，区块链信息就会受到影响，从而导致区块链信息的丢失。因此，要想确保区块链信息的有效保存，就必须确保网络维护和维护良好。

综上所述，区块链信息的保存时间受到网络硬件和软件环境、网络安全性以及网络维护和维护等因素的影响。一般情况下，区块链信息的保存时间可以达到几十年，甚至几百年。因此，要想保证区块链信息的有效保存，就必须确保网络硬件和软件环境、网络安全性以及网络维护和维护等处于良好的状态。

② The magical blockchain allows data to be retained forever

At the beginning of this year, before the Bitcoin heat wave had completely passed, another "torrent" couldn't stop the fire. This is the blockchain technology that has been hotly speculated in the financial and insurance fields recently, and has even made a strong presence in the stock trading and voting industries.

When talking about the recent hot spots in various industries, this technology must be one of them. Data illustrates: So far, the world’s largest investment projects in 2016 are all related to blockchain, with investment amounts reaching US$55 million and US$60 million respectively, while nationalThe largest blockchain project in China was also announced at the end of September this year with an investment scale of more than 20 million US dollars.

First of all, normatively speaking, this is a new application model that comprehensively uses computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. As we all know, Bitcoin, as a global encrypted Internet currency, was developed based on blockchain technology. The support of smart contracts on the blockchain has made a wider range of point-to-point transfers of digital assets other than Bitcoin a reality. It is not difficult to understand why blockchain technology has become compelling as the cornerstone of the Internet of Value.

So why is blockchain so attractive? If today’s Internet is the point-to-point transmission of information through the TCP/IP protocol, it is the information Internet, then the point-to-point transfer of value (such as electronic currency, electronic assets, etc.) without a third party is made possible by blockchain technology.

In layman’s terms, blockchain is a decentralized distributed accounting system. Nodes in the system do not need to trust each other. They jointly maintain a ledger through a unified consensus mechanism, and each node has a complete data record. Blockchain Blockchain, blocks of transactions are connected together through cryptographic algorithms, making the entire ledger open, transparent, traceable, and non-tamperable.

Compared with traditional third-party institution credit transactions, the process of blockchain in digital payment can be described as the following diagram:

③ What is the concept of blockchain

Literally understood, blockchain includes two concepts: block and chain. The blockchain itself is composed of blocks, and the network built by linking different nodes together is the blockchain. The main function of the blockchain is to store information. Any information that needs to be saved can be written to the blockchain or read from it.

Each block stores: some valid record or transaction; information involving the block; links to the previous block and the next block through the hash of each block - which can be considered a block The unique code of the fingerprint.

Each block therefore has a specific and immovable position within the chain, as each block contains information from the hash of the previous block. The entire chain is stored in every network node that makes up the blockchain, so an exact copy of the chain is stored among all network participants.

Uses

Essentially, blockchain can be used to store any type of information that must remain intact and be more secure than going through a middleman. , decentralized and cheaper ways remain available. Additionally, since the stored information is encrypted, its confidentiality is guaranteed as only those with the encryption key can access it.

Using blockchain in healthcare. For example, health records can be consolidated and stored on the blockchain. This means that every patient's medical history is secure and, at the same time, available to every authorized doctor, regardless of the health center where the patient received treatment. Even the pharmaceutical industry could use this technology to authenticate medicines and prevent counterfeiting.

Blockchain is also very useful for managing digital assets and documents. The problem with digitization so far has been that everything is easily copied, but Blockchain allows you to record purchases, deeds, documents or any other type of online asset without it being counterfeited.

④ What is the Bitcoin blockchain technology that Microsoft is interested in?

Blockchain is an important concept of Bitcoin, which is essentially decentralized. The database also serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet data. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. Lightweight Bitcoin wallets use online confirmations, which means no blockchain data is downloaded to device storage.
Many altcoins of Bitcoin also use the same design, but are slightly different in proof of work and algorithm. For example, using proof of stake and SCrypt, etc.

Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “Genesis block".
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left a sentence in the genesis block that can never be modified:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (on January 3, 2009, the chancellor was on the verge of implementing a second round of bank bailout)."
It was then that the British chancellor of the exchequer, Darling, was forced to consider a second bailout of the banks. In a time of crisis, this sentence was the headline of a front-page article in The Times that day.
Blockchain's timestamp service and existence proof, the time when the first blockchain was generated and the events that were happening at that time are permanently retained.
The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is a blockchain engraving service, using the above principles. Users can engrave text on the blockchain through this service and save it permanently.
Bitcoin, Litecoin, Ruitai Coin, and Qianjin Card are all digital currencies based on blockchain technology.
