块栈-它是什么？

To understand how Blockstack can help revolutionize the Internet in terms of allowing people to control their own data, we must first understand how this technology works. Each Blockstack node contains its own book of domain names and IP addresses to which these domains will eventually be resolved. According to the White Paper published by Blockstack in May May, domain name transactions on the network include "registrations, transfers and updates of data. These operations are encrypted in the base block chain through the transaction and use the Remote Caller Function (RPC) to perform work and update their own database " .

Blockstack aims to implement a decentralized DNS system to resolve domain name queries. As mentioned earlier, the whole platform is based on Bitcoin blockchain, which is used to register and protect domain names using a decentralised book, making the whole system more secure than a traditional DNS . The technology also promises to protect against cache poisoning and is resistant to censorship. Another important advantage of platforms such as Blockchain or Ethereum are decentralized applications or "dApps", which provide privacy and anonymity, operating on a P2P network and not on a single computer.

Blockstack is a very interesting blockchain project with SEC tokens sale approval. The company is building the first decentralized internet platform which gives users full control of their data and network apps. Blockstack offers users the platform where all decentralized apps can be run on the browser and users don’t have to upload private data (text, images, video, files).

Blockstack has its own blockchain called the Stacks blockchain which is fully compatible with Bitcoin. Blockstack re-uses Bitcoin’s computing power and its blockchain for settlement and security. The main product called Blockstack Authenticator is connecting users with one ID to all different Apps in the ecosystem. Idea behind it is utilizing single sign-on and authentication works directly on the chain on the Stacks blockchain itself. The user after using the ecosystem by signing out takes all his information with him. Blockstack combines Decentralized identity system, Decentralized domain names and Decentralized storage network. 

Instead of building the new Proof of work chain the creators decided to use Proof of transaction (PoX) consensus. Miners compete to mine blocks by sending bitcoin to participants in the network. This bitcoin becomes proof of computation, and by proxy enables the Stacks blockchain to share CPU resources keeping additional data out of the Bitcoin chain. Stacks tokens are consumed as “fuel” to register digital assets on the network and to publish/execute smart contracts among other functions on the network. One of the biggest partnership announcements by Blockstack was with Blochain.com where they promised to start integrating Blockstack’s native token into complete list of Blockchain.com products.

The Blockstack project is definitely worth looking at but their tokeneomics is very difficult to understand and the circulation supply seems infinite unless it will change in the future. Do not let my point of view to put you off this project. Also please do your own research and check the website https://stackstoken.com/ with lots of useful information about the project.

Named "Web 3.0" by some, Blockstack promises to raise the status quo of the current internet by creating a completely new, decentralized internet that allows users to control their own data by storing it locally on their own devices, instead of allowing mega-corporations to store it on their own servers and use it according to their own needs. Built on Bitcoin Blockchain, Blockstack is a key/value pair registration and transfer system that represents a dramatic departure from the way the Internet works and, if successful, will effectively end all tracking and identification activity across the Internet. .

Applications running on Blockstack are decentralized and serverless. The system eliminates intermediaries such as Google, Facebook or WhatsApp, allowing users to send information directly to each other, allowing them to control their own personal data. The digital book (blockchain), which is used to track all information, is a peer-to-peer network that is distributed to millions of computers around the world, which means that no individual has control over any personal data . The new technology aims to change the way the Internet works today by replacing current services such as DNS, Public Key Infrastructure (PKI) and cloud storage, allowing users to manage their own data and online traffic.
Like Linux, Blockstack is an open source project with GPLv3 license for basic technology. Just as non-profit organizations and commercial entities can both develop applications and services on Linux as long as they comply with the license terms, Blockstack also provides developers with the ability to build decentralized applications (dApps) and services based on existing blockchain infrastructures in a way that would give users control over their own data.

Blockstack is the company behind the blockchain Stack. Founded in 2013 and headquartered in New York City, Blockstack PBC has employees in Canada, Europe, and Asia. Blockstack's software is open source, with a global community of over 7,000 members.

Blockstack recently launched Testnet Stacks 2.0, an update that will allow developers and miners to participate in Blockstack's newest consensus mechanism, Proof of Transfer (PoX). I will discuss this topic in a moment.

What fascinates me most about BlockStack is their commitment to the bitcoin network, and the level of adoption that the network can already boast.

BlockStack gets the consensus of the network, through a simple but very clever mechanism known as Proof-of-Transfer (PoX), and it is this mechanism that uses the bitcoin network and its security, to allow the Stack layer (blockchain from BlockStack) to enjoy a similar level of security. How it works?

The native asset on the BlockStack network is the coin STX, and a consensus protocol ties BTC to STX and STX to BTX on an economic incentive basis.

Miners who want to secure Blockstack use Bitcoin as a means to give them a chance to build and propagate a block on the Stacks network.

Who builds the next block in the Stacks network is decided in the form of a competition.

In order to participate in the contest to be selected as the leader to build the next block miners must send any amount of BTC to a designated address for what is known as the Rewards Set, or prize pool.

The more BTC they deposit, the higher their chances of being selected to produce the next block. But the size of the BTC deposit itself is not the only parameter here. The other parameter is VRF, or Verifiable Random Function. This is a cryptographic function (similar functions are used by Algorand and Cardano to secure their networks) which is a kind of lottery with cryptography behind its randomness, security and verifiability.

In a nutshell we can say that the size of the BTC deposit x VRF score = determines the chances of a miner to be chosen as a Block Leader who will build a block and join this block to the Stacks network. Why would such a miner "lose" valuable BTC and take part in such a lottery? Well, in order to win 500 STX coins = because that's how much a miner is rewarded for a block in this network. 500STX is additionally generated supply (minting) in the Stack network. 

Blockstack is a decentralized computing network and app ecosystem that puts users in control of their data and digital identities. It allows users to access a wide range of applications that do not require trusting a third party with personal information. The project aims to provide a secure, private, and user-centric internet experience. I believe Blockstack has a lot of potential and could revolutionize the way we interact with the internet.
