Why we need IPFS

One, IPFS compared to the traditional underlying protocol http

1, http/https :is a bottom transfer protocol, so far has been used for 25 years, a technology used for a long time there will be drawbacks

WeChat sends a photo to someone else, you need to be uploaded to the center of the point of the server, the receiver downloads it from the center of the point of view, the photo is considered to be a successful transmission. It's like a hundred cars on a road, it's bound to be a traffic jam. Double eleven shopping is too card, Spring Festival 12306 can not buy tickets, is because of the disadvantages caused by centralization.

2. IPFS is distributed storage, fragmented transmission, did not change the nature of the Internet, only changed the traditional way of storage.

Send a photo, the file is broken up, each file everyone for 256KB, transmitted to various nodes. One road will traffic jam, build hundreds of roads to solve the problem of traffic jam.

Two, low cost

The emergence of a new technology, if the cost is too high, but also can not replace the old technology. Now HTTP is centralized, monopolized by Ali Cloud Baidu Cloud and these big heads. But IPFS is a decentralized server, it has servers all over the world, if one of the servers bid 1 yuan, the other out of home 0.5 yuan, then we naturally choose 0.5 yuan of servers, there is competition, the price is naturally not too high. Then another bandwidth costs. Now the Ali cloud Baidu cloud servers are set up in the first and second tier cities, the cost is high, so the bandwidth fee is naturally high. We watch movies in Aqiyi, a movie downloaded 10,000 times, then Aqiyi will have to pay Baidu cloud 10,000 times the download fee. Another is the cost of storage, is a hash de-emphasis, we micro credit is free, right, but if the file sent many days did not open the download to the phone, then it will show the missing file, this is because and data storage is very expensive, Ma Yun they want the server to maintain, can only delete our data. Then IPFS will not have such a problem, it will automatically de-weighting, leaving only five to two or three hundred points of backup, which saves storage space, but also saves costs.

Three, secure and naturally hacker-proof

We often get harassing phone calls because our information is leaked when we register online, which is the insecurity of centralization.

IPFS is distributed bookkeeping and distributed storage. It will break up the files, each file will have its own a hash value, this hash value is equivalent to an ID card, only with this hash value can we get the file fragments, even if we get the file fragments, it's just a fragment, the hacker comes in and doesn't know what it is, so the information won't be leaked, it's very safe.

Four, the data is permanently stored

If you put an egg in the same basket is not safe. For example, a 911 event, when the plane crashed into two buildings, the biggest loss is not two buildings, but inside the company's server room data, the server room was destroyed, the data is gone, the company suffered huge losses. This is the downside of centralized storage

But IPFS has servers all over the country, and even if there is a natural or man-made disaster and the general servers are destroyed, the remaining servers in other places still have backups, and the data can be repaired nearby, so it can be permanently saved.
