Blog Source - Cryptomantraa.com whatisblockchain.com ethereum.org According to xinchaincaijing.com , due to the impact of the Snowfall Agreement, the prices of Dogecoin (DOGE) and Shiba Inu (SHIB) have plummeted recently. Dogecoin (DOGE ) and Shiba Inu (SHIB) have suffered the most in the recent market crash, so cryptocurrency enthusiasts have turned to coins with strong marketability. Snowfall Protocol (SNW) has seen an influx of investors into its network. Snowfall Protocol (SNW) enhanced existing DeFi operations and wowed crypto enthusiasts around the world with its massive pre-sale growth. The value of Snowfall Protocol (SNW) has mainly increased during its pre-sale round that is about to complete. Markets Drag Dogecoin (DOGE) Down The world’s largest memecoin, Dogecoin (DOGE), has failed to weather the blow of market bears. The price of Dogecoin (DOGE) fell by about 27% in the last week . Even on the weekly chart, Dogecoin (DOGE) is down more than 5% . These declines caused the price of Dogecoin ( DOGE ) to drop to $0.0719. There are many reasons why Dogecoin (DOGE) crashed. The two biggest, however, are Elon Musk ’s tweet saying he’s stepping down as CEO of Twitter , and a recent report suggesting a sea change in the Dogecoin (DOGE) ecosystem . The report suggests that Dogecoin (DOGE) will abandon the proof-of-work consensus mechanism in favor of a proof-of-stake consensus mechanism that crypto enthusiasts dislike. Shiba Inu (SHIB) in extremely cold water Shiba Inu (SHIB) is a blockchain-based altcoin built on top of the Ethereum network. However, Shiba Inu (SHIB) was primarily developed as an alternative to Dogecoin (DOGE) . Shiba Inu (SHIB) has since become one of the most traded cryptocurrencies. Shiba Inu (SHIB) was in the news recently when its developer, Shytoshi Kusama , announced that Shibarium was coming soon. Shibarium will be a layer 2 solution that will increase transaction volume on the platform. However, recent developments by Shiba Inu (SHIB) developers have not received much support from the market. Shiba Inu (SHIB) prices continue to fall frictionlessly. Shiba Inu (SHIB) is down more than 11% over the past month . Therefore, Shiba Inu (SHIB) is currently trading at $ 0.00000817 . What is a Snowfall Protocol? Snowfall Protocol (SNW) is a blockchain-based cross-chain communication platform. With the Snowfall Protocol (SNW) , a unique interoperability model emerges. A favorite among investors looking to invest in projects with guaranteed growth prospects. The Snowfall Protocol (SNW) was created to remove technical barriers that hinder communication between different blockchain networks. Snowfall Protocol (SNW) is the first blockchain platform designed to facilitate the cross-chain transfer of fungible and non-fungible tokens (NFT) . To enable the exchange of non-fungible token chains, the Snowfall Protocol (SNW) uses an exchange protocol. However, to enable fungible token chain swaps, the platform uses a canonical token bridge. The platform also promises that cross-chain transactions will remain error-free on its network. The platform allows its users to share assets between popular non- EVM and EVM networks. The Snowfall Protocol (SNW) allows users to exchange crypto across other blockchain networks without any technical issues. Snowfall Protocol (SNW) can be used in all market segments, so it has a large ecosystem that helps it build a large user base. Snowfall Protocol (SNW) can be used in DeFi , infrastructure cryptocurrency, stable currency and NFT fields. Snowfall Protocol (SNW) successfully raised $ 3 million during the pre -sale period, and the commercial price of Snowfall Protocol (SNW) has now increased. However, experts expect the project to surge another 5,000% in the coming months . Blog Source - https://whatisblockchain.com/ What are IPFS NFTs ? In NFT creation, blockchain is an excellent way to handle minting, bookkeeping, immutable metadata across multiple nodes. At the same time, it is difficult to store large amounts of data on the blockchain due to the high cost of replicating data among thousands of nodes in the network. Therefore, the necessity to store and secure NFT data off-chain marks the beginning and launch of IPFS (Interplanetary File System). IPFS can help solve these problems and ensure the durability and accessibility of NFT data stored on the decentralized network. IPFS is a peer-to-peer version-controlled file system and hypermedia protocol for storing and retrieving data.
NFT , NFT stands for file and NFT metadata Non-fungible tokens, or NFTs , are a special kind of crypto asset. Unlike fungible tokens, they are not fungible because each NFT has a unique on-chain signature. So it's no surprise that NFTs are being used to represent digital art and digital collectibles. However, it's worth pointing out that NFTs can represent any unique digital or physical item. This representation is usually done by assigning an NFT representation file to the NFT . However, it is important to note that these files are not stored on the blockchain. After all, this has economic and technical consequences, since blockchains were not designed to store large files. Instead, developers use cloud storage solutions to store files representing NFTs . IPFS is one of the best decentralized options for this purpose (more on that below). Also, after the files are properly stored, the developers fetch their URLs and add them to the NFT metadata. Additionally, the latter includes some other details about the NFT , usually in the form of a JSON file. Just like the files representing NFTs , developers tend to store NFT metadata files in the same way. Therefore, IPFS NFT metadata storage tends to be the most common solution. The actual detail contained in the NFT smart contract is a link to the NFT metadata ( URI ). Of course, smart contracts also include other standardized information. However, the exact details depend on the type of NFT ( ERC-721 , ERC-1155 , SPL , etc.). Finally, once Web3 developers deploy the NFT smart contract, they create (mint) the NFT . During this process, the on-chain transaction stores the NFT metadata link ( URI ) on the blockchain. What is IPFS ? The Interplanetary File System or IPFS is a distributed system for uploading, storing and accessing websites, applications, data and files. Furthermore, Protocol Labs developed this peer-to-peer (P2P) hypermedia protocol to preserve and grow human knowledge. After all, IPFS makes the web more resilient, scalable, and open. Additionally, as a P2P file-sharing protocol, IPFS enables users to host and access content in a decentralized manner. Additionally, user operators host a portion of the overall data, which creates a unique and innovative system for storing and sharing files or other content. Also note that IPFS is not location-based like traditional HTTP systems. Instead, it uses a content addressing strategy. Therefore, all content in the IPFS ecosystem has a unique hash value as a content identifier ( CID ). Therefore, IPFS users can find any file, website, data, etc. based on content rather than location. Essentially, in order to find specific data, IPFS utilizes a cryptographic hash unique to the requested content. Additionally, IPFS also identifies content by linking it together. How IPFS Works If you want a more in-depth look at how IPFS works, be sure to check out the documentation for the protocol. However, a quick understanding of the following three principles will help you appreciate IPFS NFTs : Identification through content addressing - with IPFS , content is found by "what's in it" rather than "where it is located". This is possible because every piece of content in the IPFS protocol has a CID (a unique hash of the content's origin). Content linking via DAG (Directed Acyclic Graph) - IPFS uses a Merkle DAG where all nodes have an identifier in the form of a hash of the node's content. Additionally, IPFS typically splits user content into parts of blocks to build a Merkle DAG representation. This means that different file parts can come from multiple sources and still be authenticated effectively. In a way, this is similar to using BitTorrent , which allows you to get files from multiple peers at the same time. Content Discovery via DHT (Distributed Hash Table) - IPFS uses DHT to find out which nodes are hosting the content queried by the user. Also, since a hash table is essentially a key-to-value database, a DHT is a table split across peers in a distributed network. So to find something, you need to query these peers. What are IPFS NFTs ? At this point, you know what NFT and IPFS are . So, you probably already have a solid understanding of what an IPFS NFT is . However, since the term " IPFS NFT " can be a bit confusing, it may not be enough to know what an NFT is and what IPFS means. Therefore, an explanation is needed. IPFS NFTs are not non-fungible tokens "owned" or "minted" by IPFS. Instead, the term " IPFS NFT " refers to all NFTs that use IPFS to store files representing NFTs , NFT metadata, or both . Also, in the same way, " IPFS NFT Metadata" focuses on NFT metadata files stored using IPFS . IPFS and NFTs : the relationship Most NFTs function by storing data off-chain. In NFTs , URLs are used to point to data somewhere on the internet. As you know, links may change, disappear, or take you somewhere completely different than you expected. Here's an example scenario from above: March 11 , 2021 , is the day Mike Winkelmann made history. Most people know him by the name Beeple , who sold the “ Everydays : The First 5000 Days ” NFT for $ 69 million . Imagine you bought that NFT and can access it via URL , the data is stored off-chain. You open the link expecting to see your beautiful NFT art, but what you see is: That would be a problem, especially since you just paid $ 69 million for it. Most of us wouldn't buy an NFT at anywhere near that price , but it could happen to anyone who buys an NFT regardless of its price . So, what's the easy solution? IPFS . As a network that uses cryptography and is related to the blockchain, your file doesn't come from a standard URL , and you can be sure it's always there, no matter what. For example, Beeple 's work is stored on IPFS , and many other NFTs use IPFS as primary or secondary storage. With IPFS , you use a network of different hosts to help store your files (as long as someone is hosting them on the network), rather than accessing content from a specific domain or server like plain HTTP . If you've heard of Filecoin , it's a coin mined by users who dedicate storage servers to the IPFS network and act as an incentive for hosts to keep the network up and running. Currently, it’s a bit murky as to who is responsible for storing NFTs — the artist or the buyer. Anyway, if you ever buy an NFT , I would recommend using IPFS to back up your files. Should you use IPFS for NFT storage? There are certain projects and NFT utilities that can actually provide additional value to users by using a centralized storage solution for NFT representation files and / or NFT metadata files. However, everyone involved in Web3 development should strive for an appropriate level of decentralization. Therefore, we believe that decentralized storage solutions are the way to go. When it comes to these solutions, IPFS is often the best choice. Now, before you start using NFT IPFS solutions, make sure you understand the main pros and cons of using IPFS for NFT storage. One of the main disadvantages of IPFS is that it does not store files permanently because it does not use blockchain technology. However, this is where Filecoin neatly complements IPFS . On the other hand, IPFS has some distinct advantages: Inefficient – IPFS ’s P2P system retrieves content from multiple nodes at the same time, which makes it very efficient. This can also save a lot of bandwidth. After all, increased efficiency helps reduce system costs. Resilience - IPFS provides a highly resilient system by simplifying the creation of networks for mirroring data. Additionally, IPFS content is self-versioning due to content addressing. Decentralization - Information censorship and single point of failure issues are at the heart of centralized storage solutions and Web2 in general. Therefore, the decentralized nature of IPFS eliminates these problems by providing a flat and open network. Availability - By facilitating the creation of a resilient network, IPFS enables more durable availability. For example, this increases connectivity in developing countries or those with slower coffee shop WiFi connections. How does IPFS store NFT data? IPFS is an open-source hypermedia protocol that allows peer-to-peer (p2p) decentralized data storage through: simplified sharing , censorship resistance , and easy retrieval . IPFS decides to move data around the web and uses its content address and its file versioning advanced functions and data structures to find what you ask for. The following three interdependent basic steps constitute a complete IPFS ecosystem. Step 1 : Content Addressing via Unique Identifier Once a user uploads NFT data on IPFS , they receive an IPFS hash of the content, known as a CID . A CID is a unique identifier or address used to refer to NFT data of content, regardless of how and where it is stored. CIDs are created from content. Therefore, using CIDs to reference NFT data prevents issues like weak links and rug pulling. IPFS follows specific data structure preferences, conventions, and IPLD , from original content to IPFS addresses, which uniquely identify content on the IPFS network . The next step is to explore how to embed links between content into the content address through the DAG data structure. Step 2 : Content storage and linking via DAG IPFS provides a decentralized data storage and retrieval method to preserve NFT data for a long time. The Persistence layer in IPFS uses cryptographic proofs to ensure the persistence and persistence of NFT data over time. In terms of NFT data links, IPFS uses a Merkle DAG optimized for representing directories and files . Merkle DAGs can be built in a number of ways . To build a Merkle DAG representation of stored NFT data , IPFS initially splits it into blocks. Splitting it into chunks means different parts of the file can come from different sources and can be authenticated quickly. Merkle DAGs also provide another important property: if you have two similar files, parts of different Merkle DAGs are used to refer to the same subset of data. It makes it easier to transfer different versions of large datasets (such as genomics studies or weather data). The reasoning behind this is that you only need to transfer the newly changed parts instead of creating completely new files each time. Therefore, the entire NFT data is linked and represented through Merkle DAG . Step 3 : Content retrieval via Distributed Hash Table (DHT) IPFS uses a distributed hash table to find which nodes host NFT data. A hash table represents a key-value database. This hash table is distributed across all peers in a distributed network, where libp2p handles connections and interactions between peers. libp2p queries the DHT to understand and find which nodes store each block that makes up the NFT data. Once you have found the content, you need to connect to that content ( NFT data) and retrieve it. IPFS uses the Bitswap module for this purpose to establish a connection with a peer and send a demand list (a list of all blocks containing the desired NFT data). After receiving the requested content blocks, they can be verified by hashing and comparing their CIDs . These CIDs also help with block deduplication. How does Libp2p support connection multiplexing? It is not easy to establish a connection and maintain its fee. With IPFS , Libp2p enables connection multiplexing between peers with high interoperability and eliminates the need to set up multiple connections differently for each service. The IPFS ecosystem creates CIDs for content and links them by generating an IPLD Merkle DAG . Content is retrieved using the DHT provided by libp2p , and users can then download it using a multiplexed connection. All of these are kept together by the middle part of the stack, linked by a unique identifier. How to use IPFS to store NFT digital collections ? IPFS has received a lot of attention because of its persistence, persistence and fixed characteristics. There has been a surge in demand for data management systems and storage with easily retrievable and secure CIDs , enabling users to adopt IPFS best practices. To ensure the storage security of NFTs , it is recommended to at least start using IPFS as a secondary backup. With IPFS , creators of NFTs can immediately reap the benefits of decentralized, immutable, and verifiable storage. Creators can seamlessly push content to IPFS to create an immutable link to the NFT metadata and ensure content is permanently stored. Blog Source - https://whatisblockchain.com/ Blockchain is an important concept of Bitcoin, which uses block chain data structure to verify and store data; uses distributed node consensus algorithm to generate and update data; uses cryptography to ensure the security of data transmission and access ; A new distributed infrastructure and computing method for programming and manipulating data using smart contracts composed of automated script codes.
It is essentially a disintermediation database. At the same time, as the underlying technology of Bitcoin, it also has new application modes of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Through this application mode, blockchain technology can achieve the following three functions: first, ensure that the data on the chain cannot be tampered with or forged, and improve the credibility and credibility of the data; second, realize the traceability of transactions, do To traceability supervision and responsibility tracking; thirdly, smart contracts can be automatically executed based on contracts, thereby improving work efficiency and reducing operating costs. What is the blockchain? What is the popular explanation of the blockchain? 1. What is blockchain? The key to answering this question is: Never mind what a blockchain is. Many people don't understand what a blockchain is because they are obsessed with the concept of "what is a blockchain?" Attack", "Byzantine general problem" and other concepts are confused. For example, if I ask you "what is a mobile phone?" Don't look down, just think about it. Define "mobile phone". The answer you give must not be "a portable phone terminal that can be used in a wide range" (taken from Baidu Encyclopedia). I can't read this definition well. You will say: Mobile phones are used to make calls, send WeChat, use Douyin, and watch Moments. In the same way, let's not worry about the technical principle of the blockchain, first ask "what is the blockchain for?" Blockchains are used to collectively record public data, or more narrowly, to keep accounts. You said that you can use a computer to keep accounts, but why do you need a blockchain? Because you keep your own account and others don't believe it. Who are you? Why do others believe what you remember? For example, you recorded in your computer that Zhang San owes you 10,000 yuan, and Zhang San said that I also recorded in your computer that you owe me 1 million yuan. what to do then In the past, it was solved like this: find a notary, and the accounts of both of you will be recorded with the notary. If there is a dispute, the account book of the notary shall prevail. That's what banks do, for example. Both of you have deposited your money with him, and there are records of transfers and loans. The blockchain solves it like this: when you keep accounts in your computer, Zhang San also records the same data in your computer. After you record it, you two check each other and agree. This account will be officially recorded. up. The middle does not require the participation of a third party or the so-called "authority" or "certification agency". The way everyone keeps accounts together is also called "distributed" or "decentralized", because everyone keeps accounts, and the accuracy of the accounts is determined by a program algorithm, not an authority. This is the blockchain. After the core is over, the blockchain is as simple as that, a ledger for common accounting. Of course, in the actual application of blockchain, the number of participants can vary, and it will also be applied in many fields including digital finance, Internet of Things, digital assets and so on. For example, in the field of games, everyone records the ownership of game props, prop attributes, etc. together. Bitcoin is the largest application of blockchain in the field of digital finance and digital currency. You say: Huh? Is it that simple? Yes, it's that simple. The rest is a matter of how the technology is implemented, and you don't need to understand it. Just like you only need to know that 4G is faster than 3G, you don't need to know what 4G is. Just make myself dizzy. 2. Let’s talk about Bitcoin in detail Now it is not only you and Zhang San who have to keep accounts, but also Li Si Wang Wu Zhao Liu Wu Qi and their millions of descendants and grandchildren. Millions of people have to keep accounts together. How to record? Same as before, every time an account is transferred, everyone’s computer records it, and then checks with each other to ensure that the accounts of millions of computers are exactly the same, and the account is officially recorded. This is Bitcoin. After the core is over, Bitcoin is as simple as that. Millions of computers keep an account together, and the books are all the same. The account records how much money (bitcoin) each person has. The rest is a question of how to implement the technology. You don’t need to know how to achieve it in detail. You just need to know that the Bitcoin network has been running for 10 years without any major problems. 3. Finance is the ledger You will say, according to what you say, Bitcoin is just an account, why is it so valuable? If you think about it carefully, your deposits, your stocks, and your funds are just a series of numbers in other people's books. The difference is who owns the bookkeeping pen. Going a little further, the real reason why China and the United States are currently furious and arms race in blockchain finance is to win the pen that keeps accounts for the world. This we explain in detail later. You deposit the money in the bank, and the bookkeeping pen is in the hands of the bank. You can think about it deeply, if one day, the bank’s system goes wrong and the money balance in your account becomes 0, how can you prove that there was 38,600 in your account? Or if one day, you are framed by someone and all your bank accounts are frozen, what should you do? It is obviously your money, and if it is not deposited in the bank, it cannot be frozen. If you save it now, it no longer belongs to you. Isn't this setting weird? Of course, this kind of thing will not happen in our country with a sound legal system and advanced technology. But what about some poor and backward countries where the banks may fail at any time and the local currency may be worthless at any time? How can blockchain change this? If this account is recorded on a blockchain that is operating normally, then when the bank says that its computer is broken and cannot find your deposit record, you can tell him, it’s okay, there is a record in my computer, and Not only in my computer, but also in millions of other computers that have the same records as my computer. Likewise, on a functioning blockchain, a bank cannot freeze your account. Because your assets are no longer a string of characters that only exist in its computer, but are widely recognized in tens of millions of computers. At the same time, blockchain has extremely tenacious vitality. The reason why Bitcoin has been able to survive for so many years despite being strictly banned by many countries, and its price is getting higher and higher, is because it is too difficult to be banned. There are hundreds of thousands of computers in the world that record the same Bitcoin ledger, distributed in school computer rooms, ordinary houses, deep mountains and forests, and deep in the wilderness in dozens of countries. No matter how it is fought, as long as there is a machine in the world still running the Bitcoin ledger, it will not really die. The question of what is the blockchain is answered here. The following are some of my views on the future efforts of China and the United States in the field of blockchain finance. This is much more exciting than the blockchain itself! 4. Next Generation World Currency I am here to talk about the advantages of so many blockchains, not to sing the praises of Bitcoin. It is true that Bitcoin is a very successful experiment combining economics with computer technology. Its success has also allowed the smartest people in the world to see the possibility of blockchain subverting the current world monetary system and economic structure. Take Zuckerberg of Facebook, for example. If we want to understand the profound intentions of yesterday's news, we also need to raise our eyes to at least the same height as Zuckerberg. When we mention the money laundering risk, difficulty in supervision, and difficulty in control of the blockchain, we often unconsciously think that the country will definitely suppress it, because it is not conducive to the country's economic order. However, what if we don't always think about how to defend against its possible harm to us, but instead polish it into a sharp blade, which can be used to expand the territory and spread the Chinese civilization? If, I just mean if, we don't take Blockchain finance is used in the national economic system, but is it used in the entire world economic system? As mentioned before, compared with banks, blockchain finance has three very prominent advantages : 1. Open an account with one click, without any procedures such as identity proof 2. The circulation is open, transparent and controllable, so there is no need to worry about the sharp depreciation of the currency price 3. Anti-censorship and anti-freeze These three characteristics may have a negative impact on the economic system of the country, but if they are used to enter the economic system of other countries, they are three extremely sharp knives. Let's boldly imagine what we can get with the extremely convenient and easy-to-use Alipay/WeChat mobile payment plus the unkillable blockchain finance/Bitcoin: There is no need to set up any bank outlets, and no need to reach an agreement with any country, so that people from all corners of the world can use RMB or digital currencies controlled by China to settle accounts with just a mobile phone. And the most ruthless thing is: other countries can't ban it even if they want to. We can get such a new type of world currency and new APP products: Open an account for free with one click on your mobile phone Transfer money without borders Excellent user experience Very high security Anti-censorship, anti-freeze Anti-inflation, exchange rate stability Big country endorsement Far from it, this could dramatically improve the lives of the billions of unbanked people around the world, at least immediately. They will be able to obtain their own global universal free account with one click, and the currency will not need to worry about sudden depreciation or account freezing. 5. The trumpet sounds Undoubtedly, this new type of universal currency will be a new form of currency in the future, and it will also be the ultimate spoils of war in this digital world currency war. Who will be the new world financial rule makers? The internationalization of the renminbi has been going on for many years, but after all, it is still a stock competition under the original world structure, which requires a country and a continent to conquer the city. Wouldn’t it be more interesting if we could become the rule-makers of the new world currency and subvert the entire world currency pattern from bottom to top? Just two days ago, the U.S. Congress conducted a six-hour inquiry into Facebook's digital currency Libra plan. During the period, Zuckerberg said: "I don't know if I can do it, but Alipay and WeChat are desperately working on the blockchain. The horn of the currency war in the digital world has sounded. Warriors, are you ready? After reading everyone's replies and other answers about blockchain, I would like to discuss a question: Is Blockchain Really Decentralized? How Decentralized? Let me first give my point of view. The decentralization of the blockchain is a beautiful idea. At present, in practical applications, it is far from being as decentralized as everyone imagined. In most cases, one person, or a single-digit centralized organization or individual monopolizes more than 51% of the computing power. What is the blockchain? What is the popular explanation of the blockchain? Take the familiar Bitcoin as an example. Almost everyone is saying that Bitcoin is decentralized. There are tens of thousands and hundreds of thousands of mining machines distributed all over the world, which almost eliminates the possibility of conspiracy and fraud. But is this really the case? The picture below is the 2018 Bitcoin mining pool computing power ratio I found on the Internet. I will not expand on the concepts of computing power distribution and mining pools. Both Baidu and Zhihu have good answers. But through this picture, you can clearly see that even the decentralized digital currency Bitcoin, which has been blown into the sky, is not an ideal state where everyone is equal and completely decentralized. Large mining pools and large mine owners with extremely strong financial strength have monopolized the computing power. I have no intention of attacking the owners of mining pools and mining farms, because this is actually the inevitable result of the development of things. Moreover, many of them are pioneers in the blockchain industry and have made a lot of contributions to the development of blockchain. But I just want to illustrate the fact that blockchain is not equal to extreme decentralization and complete decentralization. There is no need for this. So why is the inability to fully decentralize an inevitable consequence of Bitcoin? Because Bitcoin mining can make money, and economies of scale can improve the efficiency of making money. In the earliest days, Bitcoin could not be sold for money, so the computing power was very scattered, and everyone was just for fun. But as Bitcoin becomes more and more valuable, more and more people begin to calculate economic accounts. Bitcoin mining is all about the computing power of the machine. A good machine can mine $100 of bitcoins with only 100 kilowatt-hours of electricity, while a bad machine can mine $100 with 1,000 kilowatt-hours of electricity. And a good machine requires capital investment for research and development and production. In the same way, the electricity bill generated by mining is 60 cents per degree for the average person, but it can be 20 cents to 40 cents for large mines with economies of scale. In this case, it is inevitable that the strong will remain strong, the weak will be eliminated continuously, and the computing power will become more and more concentrated. Then you may ask, Bitcoin is like this, what about other blockchain projects? Unfortunately, more or less the same.
