Dec 13, 2024 pm 09:38 PMThe consensus mechanism is the basis of blockchain technology, which ensures that all participants agree on the status of the ledger. In a blockchain network, the consensus mechanism is crucial as it maintains decentralization, validating transactions and updating the ledger without a central authority. Common ones are: Proof of Work (PoW): Miners create new blocks by solving complex mathematical problems. Proof of Stake (PoS): Validators create new blocks by voting based on the number of tokens they hold. Byzantine Fault Tolerance (BFT): A voting mechanism where a majority consensus of nodes is required to create a new block. Delegated Proof of Stake (DPoS): Validators are voted by token holders, and only elected validators have the right to create new blocks. The role of the consensus mechanism on the blockchain includes ensuring transaction security, maintaining network integrity, achieving decentralization and promoting transparency.
Detailed explanation of blockchain consensus mechanism
The consensus mechanism is the foundation of blockchain technology, which ensures that the network All participants agree on the ledger status. In a blockchain network, there is no central authority to control information, so consensus mechanisms are crucial to maintaining decentralization. The following are the consensus mechanisms commonly used in blockchain:
1. Proof of Work (PoW)
- Miners create new blocks by solving complex mathematical problems.
- The first miner to solve the problem and create a new block will be rewarded with tokens.
- PoW is an energy-intensive mechanism because it requires a lot of computing power to solve problems.
- Early blockchains such as Bitcoin and Ethereum used PoW.
2. Proof of Stake (PoS)
- Validators create new blocks by voting based on the number of tokens they hold.
- Validators with more tokens are more likely to be selected to create new blocks.
- PoS is more energy efficient than PoW because it does not require a lot of computing power.
- Newer blockchains like Cardano and Solana use PoS.
3. Byzantine Fault Tolerance (BFT)
- Voting mechanism where nodes need to reach a majority consensus to create a new block.
- BFT is ideal for networks that require high throughput.
- Ethereum 2.0 and Hyperledger Fabric use BFT.
4. Delegated Proof of Stake (DPoS)
- Validators are voted for by token holders.
- Only selected validators have the right to create new blocks.
- DPoS is more centralized than PoS but provides higher throughput.
- EOS and Tron use DPoS.
The role of consensus mechanism in blockchain
The consensus mechanism plays a vital role in blockchain and has the following main functions:
- Guaranteed transaction security: The consensus mechanism ensures that only transactions verified by the network can be added to the blockchain, thus preventing fraud and malicious behavior.
- Maintain network integrity: The consensus mechanism ensures that all participants have the same copy of the ledger, preventing forks and network attacks.
- Achieve decentralization: The consensus mechanism allows all participants in the network to participate in the maintenance of the ledger, eliminating dependence on a central authority.
- Promote transparency: The consensus mechanism provides transparency to blockchain transactions as all transactions are recorded on a public ledger.

Ordinary investors can discover potential tokens by tracking "smart money", which are high-profit addresses, and paying attention to their trends can provide leading indicators. 1. Use tools such as Nansen and Arkham Intelligence to analyze the data on the chain to view the buying and holdings of smart money; 2. Use Dune Analytics to obtain community-created dashboards to monitor the flow of funds; 3. Follow platforms such as Lookonchain to obtain real-time intelligence. Recently, Cangming Money is planning to re-polize LRT track, DePIN project, modular ecosystem and RWA protocol. For example, a certain LRT protocol has obtained a large amount of early deposits, a certain DePIN project has been accumulated continuously, a certain game public chain has been supported by the industry treasury, and a certain RWA protocol has attracted institutions to enter.

In cryptocurrency trading, stop loss and take profit are the core tools of risk control. 1. Stop loss is used to automatically sell when the price falls to the preset point to prevent the loss from expanding; 2. Take-profit is used to automatically sell when the price rises to the target point and lock in profits; 3. The stop loss can be set using the technical support level method, the fixed percentage method or the volatility reference method; 4. Setting the stop profit can be based on the risk-return ratio method or the key resistance level method; 5. Advanced skills include moving stop loss and batch take-profit to dynamically protect profits and balance risks, thereby achieving long-term and stable trading performance.

In the ever-changing virtual currency market, timely and accurate market data is crucial. The free market website provides investors with a convenient way to understand key information such as price fluctuations, trading volume, and market value changes of various digital assets in real time. These platforms usually aggregate data from multiple exchanges, and users can get a comprehensive market overview without switching between exchanges, which greatly reduces the threshold for ordinary investors to obtain information.

Bitcoin trading mainly includes three methods: currency trading, contract trading and leverage trading. Coin trading is to exchange one kind of digital currency for another, with no leverage and no risk of liquidation, which is suitable for beginners. The operation process includes registering an exchange account, completing KYC certification and recharge, and selecting trading pairs to set orders; contract trading allows prediction of price rise and fall, and can be long and short, which is divided into perpetual contracts and delivery contracts. The operation process includes entering the contract sector, setting leverage, selecting directions, and setting stop-profit and stop losses, but it is necessary to note that price fluctuations under high leverage are prone to trigger explosive positions and strictly control the risk; leverage trading is to enlarge positions by borrowing funds, which is suitable for short-term arbitrage workers. The operation steps include opening trading pairs, transferring assets to borrow coins, returning and closing interest after buying and selling. The three methods have their own characteristics, suitable for beginners

Recently, the total market value of the cryptocurrency market has exceeded US$3 trillion, arousing widespread attention and optimism. Such a scale shows that digital assets are gradually being recognized by more investors and institutions, and the market popularity continues to rise.

Platform coins are cryptocurrencies issued by digital currency trading platforms, which are mainly used for ecological construction and user rights incentives within the platform. Compared with ordinary virtual coins, platform coins are not only an investment asset, but also an important link connecting users and platforms.

In the currency circle, many veteran players will recommend that novices start with Bitcoin (BTC) or Ethereum (ETH). This is not a casual statement, but a consensus that has been verified by many years of markets.

Ethereum does not have an official trading platform, so it is recommended to trade through third-party exchanges. 1. Binance provides high liquidity and rich trading pairs; 2. OKX is known for its derivatives and Web3 wallet functions; 3. Huobi (HTX) has a stable operation and strict risk control; 4. Gate.io has rich currency selection and is suitable for exploring emerging assets; 5. KuCoin interface is friendly to support a variety of cryptocurrencies; 6. Kraken has outstanding security and compliance. It is recommended to choose a platform based on regional regulations, trading habits, currency needs and security preferences, and be sure to access it through official channels to ensure the security of assets.
