What is IPFS? What is the future of IPFS?

Let the blogger introduce IPFS today!

To understand IPFS, you must first know what HTTP is, because the emergence of IPFS is iterative HTTP.

I think everyone is familiar with HTTP. When we need to open a website to search and download certain information, we use HTTP. It is the underlying hypertext transfer protocol. It was released in 1996, and it has been 25 years since its contribution to the world is obvious to all. But over time, people gradually discovered his shortcomings. His operating principle is to concentrate all data on a central server. The server must be on for 24 hours. The load pressure is extremely high, which can easily cause the system to crash and be vulnerable to DDOS attacks. Once the above problems occur, data loss and irreversibility will occur. I believe that when you search for a 404, it means that data is lost, deleted, or maliciously tampered with.

It is for this reason that the smart brains in the world begin to collide with each other. So in May 2014, Juan Benet, who graduated with a master's degree in computer science from Stanford University, founded the protocol laboratory. The protocol laboratory is a laboratory for research, development and deployment of network protocols. It is committed to building protocols, systems, and tools to improve the way the Internet works, and it focuses on how to store, locate, and transmit information. Its goal is to solve the shortcomings of the traditional Internet through new technologies, good user experience and open source methods, and IPFS was born.

The Chinese translation of IPFS is "Inter Planetary File System" (Inter Planetary File System), which is a basic point-to-point hypertext file transfer and storage protocol. Simply put, HTTP puts eggs in a large basket, while IPFS puts eggs in baskets all over the world.

The purpose of the birth of IPFS technology is to iterate HTTP technology to solve the above-mentioned drawbacks. IPFS stores files in multiple nodes close to users, and the storage is fragmented. Traditional DDoS attacks are invalid, files are more secure, the closer the distance, the faster the download speed, and the storage cost will be reduced. What's more advanced is that due to the use of blockchain technology, historical versions can be traced back and theoretically can be stored forever. So the emergence of IPFS is iterative HTTP, its technology is more advanced, the use cost is lower, and the operating conditions are more convenient.

Over time, IPFS technology has been used in many applications around the world. Internet giants are deploying IPFS, foreign countries such as Google, Microsoft, Oracle, Amazon, Facebook, Huawei, Ali, Tencent, JD, Baidu, etc., this also illustrates a problem. The global consensus on the value of IPFS is unified, because the emergence of this project is to replace HTTP, that is, to provide humans with safer, more efficient, and cheaper storage technology. Data is an important cornerstone for recording the development of human civilization and a weather vane for the development of human civilization in the future. Without data, there is no future. With the exponential growth of data generated by the rapid development of civilization and technology, data storage technology is also constantly iterating, just as the technological revolution develops to the information revolution. IPFS is the future of data storage.

How is IPFS mining different from BTC/ETH mining?

1. The relationship between the IPFS system and the FIlecoin system: ① IPFS is just a protocol, not the mining software itself; ② The Filecoin system is the mining software itself, the token name is FIL, and Filecoin uses the IPFS protocol to run the system; ③ Filecoin and IPFS protocols are both developed and maintained by Protocol Labs. 2. How are FIL tokens distributed? There are a total of 2 billion FIL tokens, and the distribution plan consists of four parts: ① 70% as the return of mining: like Bitcoin, it is gradually distributed according to the progress of mining; ② 15% reserved Protocol Labs: as research and development expenses, the ban will be gradually lifted in 6 years; ③ 10% is allocated to ICO investors: according to the mining progress, the ban will be gradually lifted; ④ 5% is reserved for the Filecoin Foundation: as long-term community construction, network management and other expenses, the ban will be gradually lifted in 6 years.

3. How to mine?

The Filecoin system has created two mining markets: ① Filecoin Storage Market (Filecoin Storage Market) Hard Disk—Yes, it’s the size of the hard disk. What you need to contribute to the data storage market is hard disk storage space. The more hard disk space you have, the higher your mining capacity. Storage) prove that FIL will be distributed to everyone proportionally according to the size of the data you store. So everyone knows what to do: students who want to dig the first pot of gold, get your disks ready. ② Filecoin's Retrieval Market (Filecoin's Retrieval Market) Bandwidth-Provide network bandwidth. If you have bandwidth resources, you can consider mining in this market and allocate FIL according to your bandwidth. Of course, you can also participate in the two markets at the same time. It's up to you. After the Filecoin system is released, students who want to mine should act quickly and try to dig the first pot of FIL. The earlier you intervene like BTC, the higher the profit. . 4. The main technical difficulties of Filecoin: ① Proof-of-Spacetime (Proof-of-Spacetime): Proof that miners use characteristic storage space to store specific data (used for mining) within a period of time; ② Proof-of-Replication: Proof that specific data has been copied to the user's storage space; ③PFT (Power Fault Tolerance): The upgraded version of Byzantine fault tolerance, a classic problem that cannot be avoided by the communication protocol, the Byzantine Generals problem.

① Different mining principles:

PoW, the full name of Proof of Work, is proof of work.

Bitcoin/Ethereum, as well as most public chains or virtual currencies, are based on the PoW algorithm to implement their consensus mechanism. That is, according to the effective work contributed by mining, the distribution of currency is determined. The so-called mining under this principle is a process in which the computer continuously searches for the Nonce value and calculates the Hash value through exhaustive methods. Whoever finds it first will succeed in digging. Mining based on the PoW mechanism is mining that consumes a lot of computing power and electricity.

PoSt, the full name of Proof-of-Spacetime, is (storage) proof of space time.

On the basis of Proof-of-Stake consensus, Filecoin improved the consensus mechanism and became PoSt, to replace the proof-of-work PoW. In the Filecoin system, the miner completes the storage, and the user confirms that the miner completes the storage. The “confirm that the miner completes the storage” here is the Filecoin consensus mechanism (PoSt). This “confirm that the miner completes the storage” will always exist in the Filecoin network, and the user can Check it out anytime.

PoSt is generated when Filecoin verifies that miners store user data. Filecoin converts the current storage ratio of miners in the network to the storage ratio of the entire network into voting power of the miner, where the network selects a miner to create The likelihood of a new block is directly proportional to the cost of the storage they are using and the rest of the network.

Under the PoSt mechanism, miners prefer to invest in storage rather than computing power to parallelize mining calculations. Miners provide storage and reuse calculations to prove that data is stored to participate in consensus. Proof of storage (PoSt) is used to generate consensus, without wasting computing resources and energy like Bitcoin, and it can encourage miners to invest more storage space (hard disk) resources instead of computing and energy resources to contribute to the network, which is very environmentally friendly and efficient Way. Simply put, mining based on the PoSt mechanism is a mining that invests a large amount of storage space (hard disk) and bandwidth resources.

② The nature of the mining machine is different:

The essence of BTC/ETH mining machines is a data computing device.

From the initial personal computer mining, graphics card mining, and personal mining at home, mining has developed to clustered and specialized large-scale mining. Regardless of the initial CPU mining, GPU mining, or later FPGA mining, ASIC mining, large-scale cluster mining, the essence is to concentrate on improving the data computing power of mining equipment mining.

The essence of IPFS mining machine is a data storage device.

The essential difference of the mining machine makes the configuration characteristics of the storage mining machine very different from the BTC/ETH mining machine. The storage mining machine mainly used for data storage does not require too high computing power, that is, the performance of the CPU does not require too high, and the memory capacity is suitable, but it requires a large storage space, that is, the density of the hard disk per unit space is required. Large, equipped with as many hard disks as possible, at the same time, the I/O performance of data storage should be high, and the bandwidth channel should be as high as possible. Because of the special requirements of data storage, the entire mining machine must be stable, safe and not easily damaged.

③ Different mine options

BTC/ETH mine: Because it consumes a lot of electricity resources, places that can provide low-cost electricity are the first choice. Our domestic mines choose to deploy in relatively remote places such as Inner Mongolia and southwestern provinces because of the rich thermal power, wind power or hydropower resources. The internal requirements of the mine are relatively simple. As long as the ventilation and heat dissipation effect is good, the racks for placing the mining machines do not need too professional equipment, and there are no special requirements for the floor and ceiling of the mine. Mines do not require a high degree of dispersion, so such mines are relatively concentrated.

IPFS mining farm: We already know the secrets of IPFS mining: the hard disk space of the mining machine must be large, the network bandwidth must be large, and the site should preferably be in a place with high frequency of use and high population flow. Because the IPFS mining machine consumes less energy, it is not too demanding on the supply of electrical energy. Because there is a large amount of data I/O, the network bandwidth requirement is as high as possible. Because of the particularity of data storage, mining farms must be constructed in accordance with the requirements of data centers or quasi-data centers, requiring constant temperature and humidity to prevent static electricity as much as possible, and the equipment for placing mining machines must also be dedicated to professional servers. IDC data room in large cities is the first choice for large mines. It is a good choice for small mines to be placed inside residential communities. Because of the particularity of the IPFS system, the more dispersed the mines, the better. Large mines are useful, small mines are also useful, and even personal home mining equipment is as useful.

加密货币

在过去的几年里，出现了数千种新的加密货币，都声称提供了一些不同的东西。比特币是第一个，其价值在 2017 年底上涨至 20,000 美元左右，然后在 2018 年初暴跌超过 60%。比特币用了三年时间才回到之前的高位，然后在 2020 年底，在不到一个月的时间里翻了一番。 2021 年，许多大公司正在买入，华尔街著名的怀疑论者正在改变他们的论调。

什么是加密货币？

加密货币是纯数字代币。它使用密码学来规范代币的创建方式、交易方式以及安全性。而且它不使用或不需要中央银行或政府来控制或管理它们。

比特币是第一种加密货币，由一个人（或多个人）使用化名中本聪创建，于 2008 年 10 月首次在白皮书中概述，称为“点对点电子现金系统”的概念。比特币区块链是运行比特币的网络，于 2009 年 1 月推出。（现在还有许多其他区块链。）

本质上，加密货币是：

数字：加密货币完全是互联网原生的。你不能身体接触或握住它们。（那些将比特币描述为带有 B 的实物金币的插图可能会产生误导。）

去中心化：所有加密货币交易都存储在一个公共的、全局的列表或分类账上。这意味着记录同时存储在许多不同的地方（节点）。

点对点：加密货币在各方之间以电子方式交换，无需一个中央方或中间人批准交易

加密货币是如何创建的？

大多数加密货币（但不是全部）通过挖矿过程产生新的单位或货币。在这里，个人或团体（矿工）使用昂贵的计算机来竞相解决复杂的密码难题，以验证分类帐中的交易记录（区块）包。矿工因他们的努力而获得回报，这就是创造新货币的方式。 （在比特币区块链上，挖矿奖励每四年减半，以减缓新比特币的产生。）

如何使用加密货币？

如今，关于加密货币是否真的像货币一样，或者它们是否更像商品一样存在争议。 （有些人说它们应该被称为“数字资产”而不是加密货币。）但是加密货币的诞生不仅仅是为了替代您的美元和英镑。它们可以用于许多不同的事情。这些只是跟随比特币的三个例子：

莱特币 — 莱特币区块链创建于 2011 年，是比特币区块链的一个分支（代码调整）；它的创造者查理.李打算将其作为比特币黄金的白银。它的代币是LTC。

以太坊 — 以太坊区块链于 2015 年推出，专门设计用于为其网络提供去中心化应用程序 (Dapps) 和智能合约。它的代币是 Ether 或 ETH。

Filecoin — Filecoin 网络于 2020 年推出，允许人们租用计算机存储空间，例如用于去中心化网络的 Dropbox。它的代币是 FIL。

为什么有这么多？

比特币是第一种加密货币，它解决了创建数字货币的一些关键问题。但它并非没有缺陷。因此，开发人员、企业家和程序员一直忙于尝试构建满足各种不同需求并解决不同问题的加密货币。

与政府发行的货币相比，加密货币有什么吸引力？

他们是半匿名的。可以设计加密货币以便没有人可以看到您是谁或您将加密货币用于什么 — 尽管与钱包地址相关的交易是公开可见的。

他们不受政府控制。在货币不稳定的国家，人们可以使用加密货币作为购买商品和服务的替代方式。

他们是无国界的。就像互联网一样，加密货币可以去任何地方。

他们更安全。分布式账本很难被破解，因为没有一个集中的一方在控制。

交易更便宜、更快捷。虽然加密货币交易所确实会为您购买、出售或转移您的加密货币收取费用，但这些费用往往比在现实世界中跨境转移资金的费用低得多 — 而且交易的验证速度要快得多。

它们可用于执行合同。加密货币不仅仅用作一种货币形式。它们可用于存储人与人之间的合同，并可以自动执行这些合同。

未来与前景

我们仍处于加密货币时代的开端。许多货币都会来来去去，有些会变得非常有价值，而另一些则可能会降到零。

但作为一个整体，加密货币及其周围的技术和行业将继续存在。

Here is an interesting idea: a co-worker pointed me towards FileCoin, a cryptocurrency whose defense against Sybil attacks is, not proof of computation (which tends to be wasteful) or proof of stake (which I hear doesn’t work yet), but instead proof of storage -- storage of useful data. As I understand it, the blockchain includes (a) metadata about files being stored, and (b) randomly generated challenges (and responses to them) by which storage nodes prove that they're still storing the data they claim. The miner(s?) selected to win each block is a randomly selected storage node, weighted by how much data it's storing.

I think this is really exciting! Cryptocurrency's current best defense against Sybil attacks consumes as much energy as Austria, and being able to spend that proof-effort on something useful would be really neat.

(This post is not an endorsement, exactly. The whitepaper presents a couple of “threats” that don’t seem like threats to me (”outsourcing” and “generation” attacks), and, perhaps relatedly, it seems unnecessarily complicated, at least to a dilettante like me (why does replication need to be built into the protocol?; do we really need a whole order-matching engine?), and I worry that it might have been designed by starting with an incentive system that almost worked and then repeatedly plugging holes until there weren't any obvious ones left. But it does seem like a system that at least could work, which excites me.)

Blockchain Storage: Data Integrity Certification Is the Key The blockchain currently stores many types of transaction information such as A to B transfer information, temporary information, and other information that is temporarily occupying a large space because there is no other place to store it. Commercial blockchain applications deal not only with transactions, but also the business system logic which requires more abundant data, such as resource text data, numeric data, video media data, etc., which are not stored on the blockchain.⠀ Popular Blockchain Storage Projects⠀ Sia is the earliest storage, bitcoin-based storage solution. Storj is similar to Sia in that it pulls data from a network disk. It does not provide program-accessible storage. The way to prove data integrity is by having the customer and the storage party sign a contract. Both sides are likely to be in this situation. Cheating becomes expected to provide proof of data storage.⠀ The protocol lab project first made the open source software InterPlanetary File System (IPFS), which positions itself as the infrastructure of the new transport protocol. The IPFS network is similar to the P2P network that existed ten years ago, such as eDonkey and Thunder. There is no incentive mechanism for the IPFS network, so the post-protocol lab has launched a new project called Filecoin to provide decentralized storage incentives.⠀ Lambda, however, is a program-accessible storage solution. Its underlying protocols utilizes a basic file system with object storage, Key-Value (KV) storage, and other storage types. It may be extended to provide more complex relational storage.⠀ Filecoin utilizes a more mature IPFS network. On this basis, the incentives will involve the consensus of the blockchain. Those who contribute more will be rewarded more and are imperative to prevent cheating.

What is the prospect of Filecoin mining revenue? In fact, it is the wealth myth of the next generation!

When the Filecoin project was launched, I believe everyone has heard of it, so what is the revenue of Filecoin mining? Is it worth mining? What's the outlook? Let's take a moment to find out!

"BTC" was initiated by Satoshi Nakamoto on November 1, 2008. Nakamoto developed the first client program that implements the Bitcoin algorithm, and mined the first Bitcoin on a small server in Helsinki, Finland. A block-the creation block, and get a reward of 50 bitcoins, which marks the birth of bitcoin.

BTC uses point-to-point technology to decentralize digital currency, and directly trade and distribute via the network. It is a virtual encrypted digital currency in the form of P2P. Over the past ten years, Bitcoin has been seen as an outlier, it has created a new asset class that may have accumulated wealth for generations

IPFS is the best solution to solve the blockchain problem.

Since its inception, BTC was once regarded as a Ponzi scheme and has received widespread attention from the market. Its market value continues to stage a "roller coaster" with the ups and downs of the market. The initial price of Bitcoin in October 2009 was approximately $0.00076. In November 2010, the price of Bitcoin on the Mt. Gox exchange reached US$0.5 per coin. Bitcoin reached $19,850 on December 17, 2017. The highest price of Bitcoin before 2021 is $41,900.

BTC provides a safe and fast transaction method. In the P2P network, Bitcoin uses a distributed database composed of many nodes to confirm and record all transactions, and uses cryptographic technology to ensure the safety of all aspects of currency circulation. It is the first choice of many investors.

In recent years, with the iterative technology of IPFS distributed storage, the rise of FIL coins, and the IPFS/Filecoin mainnet, more and more investors have begun to pour into this market, FIL is also known as the next Bitcoin. Filecoin is an incentive layer on the IPFS distributed storage network. It attracts people to contribute storage resources, search services, and broadband resources to the IPFS network by issuing FIL, thereby building a powerful new Internet, which we call Web3.0.

The investment advantages and value of Filecoin in the future

Storage is income, and the proof of work of Filecoin and BTC is different. Filecoin only needs to provide storage space and broadband to meet the needs of obtaining identity certificates. Therefore, Filecoin can fundamentally improve human efficiency and is a true sharing economy, which can greatly promote the use of storage resources.

Because Filecoin is based on the powerful IPFS protocol, and due to the large number of applications of IPFS, Filecoin as the incentive layer of IPFS will inevitably get more recognition, further pushing up the price of Filecoin.

Blockchain is an extension and application of encryption technology, but its shortcoming is that the ability to carry data is too small. With the advent of the 5G era, facing the rapidly growing market of data, IPFS/Filecoin fills this gap and brings blockchain Great vitality and development came.

Filecion is the wealth myth of the next generation.

Some people say that Filecoin will become the next Bitcoin that creates a new generation of financial myths! First of all, the essence of Filecoin is the sharing economy. It provides the possibility of efficiently using storage devices and networks and reducing the cost of data storage and transmission. This will be the reason for becoming the next Bitcoin. At present, Filecoin is the real digital currency application landing.

As the infrastructure of the blockchain, IPFS and Filecoin together provide the best choice for data storage, and its future status is unshakable. It is also the source of investors' confidence in Filecoin.
