In the WeChat Index, we can see that the popularity of Swarm is much higher than that of BTC and ETH, almost 8 times that of BTC and 10 times that of ETH, and continues to climb, with a daily increase of 54.2%. So, what is it that supports and promotes the popularity of the Swarm project? Next, let’s explain in detail what Swarm is? Why Swarm, together with Ethereum and Whisper, is known as one of the three pillars of Web3.0. What exactly is Swarm? Swarm is a decentralized content storage and distribution network , Is a Web 3.0 stack, it is decentralized, secure and motivating. Swarm provides point-to-point storage and service solutions. It has the characteristics of DDos resistance, zero downtime, fault tolerance, anti-censorship and self-maintenance. It has a built-in incentive system that allows users to pay for transaction resources through point-to-point accounting. , And uses different protocols and technologies in the Ethereum blockchain, which contributes to the decentralization of the web. The core architecture layer is divided into four layers, which are the underlying P2P network, distributed storage, components that provide high-level data access and define APIs for basic layer functions, and the application layer.

We all know that we are entering a digital society, and data information is becoming the basic layer of the social structure. Swarm is committed to building a distributed storage system with three core highlights:

  • It is more friendly to DAPP: Swarm has built-in privacy protection, communication and redundancy. It can guarantee the integrity and availability of data even when a single node is offline. Swarm can assist DApp storage and storage without interfering with the information on the blockchain. Distribute code, data and content.
  • Users have data ownership and management rights: The Swarm network divides data into small pieces and stores them in the entire network. Swarm is a decentralized network. Node operators cannot know what content is stored on the node, and they still need to pay for storage. , That is, users have data ownership and management rights.
  • Achieve zero-cost economy: Swarm is a decentralized network. All node operators (miners) participate in the realization of a fair data economy, instead of relying on intermediaries to ensure the availability and integrity of data. Without intermediaries, there is no need to pay for the first Three-party expenses.

Swarm’s long-term vision is to give data freedom to the entire Web. Swarm-one of the three pillars of Web3.0

Swarm was launched in 2015 and was promoted by Ethereum founders Vitalik Buterin, Gavin Wood and Jeffrey Wilcke. Among them, Swarm’s protocol labels bzz and shh were created by God V, and Swarm’s white paper was also written by God V.

Swarm allows data storage, bandwidth and computing resources to support applications based on the Ethereum network. From the beginning, Swarm is considered to be the three pillars of Web 3.0 components together with Ethereum and Whisper. Ethereum’s smart contract Realized distributed logic, Constructed a huge underlying ecology of the blockchain , With the rapid development of DeFi in the past two years, the ecology on the Ethereum chain has become more and more prosperous, and the demand for data storage has become more urgent; the identity communication system in Ethereum Whisper A communication protocol designed for interaction between DApps, Constructed a message transmission channel between DApps. Swarm, which can provide solutions for storing and distributing DApp code data and blockchain data on the Ethereum chain ; This means that, because of the blessing of Swarm, the DAPP application on Ethereum realizes the storage, calling and circulation of data on the Ethereum network. The data storage on the Ethereum network can be simply and conveniently stored on Swarm, which not only helps the development of DApps, promotes the growth and prosperity of the Swarm network ecology, but is also conducive to the efficient growth of the entire Ethereum network and promotes the development of the entire blockchain. Application landing. The history of Swarm On June 4, 2021, the official Twitter of the Swarm Foundation released the latest news that the soft launch of the Bee mainnet will take place on June 13. At that moment, we felt the cheers and boiling of all Swarm fans.

The Swarm network was founded in 2015 and has been diving for 6 years. It has released Swarm Alpha version, Swarm summer version, Swarm Beta version, Swarm Live version and many other versions.

Now, the moment of the mainnet launch is coming soon!

Swarm mining logic

The Swarm network has a concept of bookkeeping.

When data enters the Swarm network, Swarm will cut each file into 4K file fragments, and then store them in different nodes. For example, if node A stores data once, it will keep an account once. Similarly, node B is the same.

As the number of bookkeeping increases, the concept of a checkbook will emerge. Every data transmission and return will be clearly displayed in the checkbook. Finally, the node (miner) can exchange the checkbook for the corresponding denomination of BZZ. In other words, the Swarm network is equivalent to a coordinating role. When there is an order for data, the data is divided into pieces, and then the content is distributed to the nodes. Therefore, if a node wants to get more orders, it can only transmit more data and obtain higher revenues if it is associated with more nodes and interacts.

In general, if we want to get more storage order probability and get more mining rewards, we not only need good hardware equipment and high-quality broadband resources, but also a strong technical team for blessing, including but not limited to Excellent bandwidth conversion efficiency, excellent ability to grab orders and take orders, and have a deep understanding of the nature of the Swarm network.

The last one makes you unbelievable because this dish is a favorite of many people.
You know, vegetables are inherently good for health because they are low in calories, rich in vitamins, minerals and fiber. However, there are some vegetables that are not as good as we think but contain dangerous toxins, which can cause cancer or death if eaten in excess. Here are 5 types of vegetables that contain many toxins that many families do not pay attention to, still eat Pi Pi every day.

1. Green tomatoes Ripe red tomatoes are delicious, but that doesn’t mean it’s unripe, you can still cook it temporarily. Because tomatoes when green contain large amounts of alkaloid elements. This substance only decreases and disappears when the tomatoes are ripe and red. So if you eat green tomatoes, the amount of alkaloids still there will cause poisoning. If it’s light, you’ll see “baby lily”, dizziness but severe can be life-threatening, so it’s better to “eat it” 2. Old pumpkin, keep for a long time Like potatoes, pumpkin is also a family favorite food, especially families with small children. However, pumpkin contains high sugar content. Moreover, if stored for a long time, it is easy to cause anaerobic respiration – fermentation and metamorphosis inside the fruit, so eating is not good for health. 3. Gourd, bitter squash In the summer, if you have a delicious soup with gourd and cooked shrimp, it will not take long to run out of rice. However, there are some gourds and squash that taste bitter when ingested, which is an alkaloid toxin such as cucurbitacin and cucurbitin B. If you eat it, the body will show symptoms such as abdominal pain, diarrhea, vomiting and diarrhea. Other, more severe reactions can cause body spasms, even death. So to be safe, before processing, you should dip a small piece of gourd and squash on the tip of your tongue first to feel the taste. If you feel bitter, leave immediately and always, but don’t regret it. 4. Sprouted Potatoes This is also a familiar food, every family eats and loves it because it is easy to prepare and good for health. But eat whatever you want, you should stay away from sprouted potatoes, but don’t regret cutting them off and cooking them with all kinds of stir-fries. Because during the sprouting process, the inside of potatoes produces a lot of solanin. If you eat a lot of this substance into the body, it can cause food poisoning. Eating regularly if there is no immediate poisoning, but in the long run, it will accumulate, increasing the risk of cancer. So better, sprouted potatoes are only planted for “green” home. 5. Pickles are still green This sour dish ensures that everyone’s tray of rice is not lacking, and every family is fascinated by eating “not the right form”. Salt cooked yellow or salt, green, are very easy to eat. But in fact, eating too much pickle is not good, but eating it when it is green, has a pungent taste, it is not good. Because the green melon is easy to contain a lot of nitrosamines, a compound that can cause cancer. You should only eat melon when it has turned bright yellow, sour, crispy, fragrant and no matter how much you crave, you should still sip a little to protect your health.
