Please explain blockchain basics in detail

Blockchain basics can be explained in detail from the following aspects:

1. What is blockchain? Blockchain is a distributed database technology characterized by data stored in encrypted form in a decentralized network. These data are organized into “blocks” and linked to each other through encryption algorithms to form a continuous “chain”, which is the origin of “blockchain”.
2. Core Features of Blockchain

• Decentralization: Blockchain data is stored on multiple nodes throughout the network, and there is no single central control point. This reduces the risk of a single point of failure and improves system stability and security.
• Immutable: Each block contains a cryptographic hash of the previous block, so once the data is written into the blockchain, it will be very difficult to modify or tamper with the data as it would require recalculation of all blocks after that block The hash value of the block.
• Data transparency: The data on the blockchain is open to all network participants, and everyone can view and verify transaction records, ensuring data transparency and credibility.
• Smart contract: A smart contract is a computer program that automatically executes the terms of a contract. It runs on the blockchain to implement decentralized automated business logic.

3. Blockchain type

• Public chain: The public chain is open to everyone, and anyone can participate in the operation, transaction and verification of its network. Bitcoin and Ethereum are well-known public chains.
• Consortium chain: Consortium chain is a blockchain jointly maintained by multiple organizations, which only allows specific members to participate in the verification and consensus process. For example, financial institutions, government departments, etc. may use alliance chains.
• Private chain: A private chain is a blockchain that is completely controlled by an organization and only allows specific members to access it. It is commonly used in internal networks to enable data sharing and business logic automation.

4. Consensus algorithm Consensus algorithm is the mechanism to achieve data consistency in the blockchain network. The main consensus algorithms include:

• Proof of Work (PoW): Miners are required to solve a complex mathematical puzzle, and miners who solve the problem will be rewarded with blocks. Bitcoin uses the PoW consensus algorithm.
• Proof of Stake (PoS): The verifier is selected based on the amount of currency held and the time of holding the currency. The verifier needs to pledge a certain amount of tokens. Ethereum is moving from

Transition from PoW consensus algorithm to PoS consensus algorithm.

• Delegated Proof of Stake (DPoS): Allows token holders to entrust their interests to other nodes, and these entrusted nodes will perform transaction verification. Blockchains such as EOS and TRON have adopted the DPoS algorithm.
• Other consensus algorithms: including Byzantine fault tolerance (BFT) series algorithms (such as PBFT, SBFT, IBFT, etc.), proof of authority (PoA), sharding technology (Sharding), etc.

5. Tokens and cryptocurrencies Digital assets in a blockchain network are called tokens or cryptocurrencies. They can be used for value transfer, payment, investment, etc. in the network. Common cryptocurrencies include Bitcoin (BTC), Ethereum (ETH), and Terra (Terra).
6. Wallets and keys Wallets are tools for storing and managing cryptocurrencies. A wallet includes two parts, a public key and a private key. The public key is similar to a bank account and can be disclosed to others; the private key is the key to controlling asset permissions and must be kept properly.
7. Blockchain application fields Blockchain technology has penetrated into many fields, such as finance, supply chain, medical care, Internet of Things, copyright protection, etc. Key applications include:

• Cross-Border Payments & Remittances: Fast, low-cost global remittances via cryptocurrencies.
• Decentralized Finance (DeFi): Using smart contracts to realize financial services without intermediaries, such as lending, trading, insurance, etc.
• Non-Fungible Tokens (NFT): Represent unique and indivisible digital assets, used in fields such as artworks, collectibles, and virtual land.
• Identity management and data sharing: Blockchain-based identity authentication, data sharing and privacy protection solutions.

The above is a detailed explanation of the basic knowledge of blockchain, which will help you better understand blockchain technology and its applications.

Please explain in detail the origin and development of Terra

Terra is a decentralized financial infrastructure platform whose goal is to provide global users with a stable payment system and value store. The following is the origin and development of Terra:

1. Origin Terra was co-founded by Korean entrepreneurs Daniel Shin and Do Kwon. Before creating Terra, Daniel Shin was the founder of Ticket Monster (TMON), a successful Korean e-commerce platform. He saw the potential of cryptocurrencies in enabling a stable and efficient payment system, so he founded Terra with Do Kwon. The Terra project was established in early 2018.
2. Token sale and public chain startup Terra conducted a token sale (private placement) at the end of 2018 and successfully raised $32 million. Its token, called LUNA, serves as the governance and security token for the Terra ecosystem. In April 2019, the Terra mainnet was successfully launched, marking the official launch of the Terra public chain.
3. Terra stablecoin (UST) and other stablecoins Terra has issued a series of stablecoins linked to fiat currencies, such as US dollar stablecoin UST (TerraUSD), Korean won stablecoin KRT (TerraKRW), etc. These stablecoins maintain their stability through fluctuations in the value of LUNA tokens, providing users with a stable means of value storage and payment.
4. Terra Ecosystem Development With the launch of the Terra public chain, Terra began to build a decentralized financial (DeFi) ecosystem. This includes protocols such as Anchor, Mirror, etc. Anchor is a decentralized savings and lending platform that provides a stable rate of return; Mirror is a synthetic asset platform that tracks real asset prices, allowing users to invest in markets such as stocks and commodities.
5. Chai payment application Terra has realized the widespread application of cryptocurrency payment by launching the Chai payment application. Chai has cooperated with many merchants in South Korea and other regions, enabling users to use Terra stablecoins for daily payments, promoting the practical application of the Terra ecosystem.
6. Cross-chain interoperability In order to further expand its ecosystem, Terra has achieved cross-chain interoperability with other mainstream blockchain platforms (such as Ethereum, Binance Smart Chain, etc.), allowing users to transfer assets and Use various DeFi services.

In short, since its establishment in 2018, Terra has gradually developed from an idea to a platform with a complete DeFi ecosystem, a wide range of payment applications and cross-chain interoperability

Please explain the Terra protocol and consensus algorithm in detail

The Terra protocol is a decentralized financial platform based on blockchain technology. Its core goal is to provide global users with a stable payment system and value storage means. In the Terra protocol, there are two important tokens: stable coins (such as UST, KRT, etc.) and LUNA tokens. Terra’s stablecoin system maintains its stability through fluctuations in the value of LUNA tokens. The following are the main components and consensus algorithm of the Terra protocol:

1. Components of the Terra protocol: a. Stablecoins: Terra has issued a series of stablecoins linked to fiat currencies, such as US dollar stablecoin UST (TerraUSD), Korean won stablecoin KRT (TerraKRW), etc. The value of these stablecoins is maintained through the LUNA token. b. LUNA token: LUNA is the governance and security token of the Terra ecosystem and is used to maintain the value stability of the stablecoin. When the market price of the stablecoin deviates from the anchor value, LUNA will adjust the supply of the stablecoin through the exchange with the stablecoin to maintain the stable value of the stablecoin. c. Governance: The Terra protocol realizes the decentralized management of the ecosystem through on-chain governance. LUNA token holders can participate in governance votes, voting on network parameters, upgrades, and other key decisions. d. Smart contracts: The Terra protocol supports smart contracts, enabling developers to build decentralized applications (dApps) and protocols on the Terra platform.
2. Consensus Algorithm: The Terra protocol uses a Byzantine Fault Tolerant (BFT) consensus algorithm called Tendermint. The following are the main features of the Tendermint consensus algorithm: a. High performance: The Tendermint consensus algorithm has a short block time and high throughput, and can support large-scale decentralized application scenarios. b. Security: The Tendermint consensus algorithm adopts a Byzantine fault tolerance mechanism to ensure that the network can still reach a consensus under a certain degree of malicious node attacks. c. Decentralization: The Tendermint consensus algorithm performs network verification and consensus through validators. Verification nodes need to stake LUNA tokens to obtain verification qualifications. The more LUNA you stake, the higher the probability of becoming a verification node. Verification nodes are responsible for verifying transactions, producing blocks and participating in the consensus process. d. Delegate Proof of Stake (DPoS): Tendermint

please continue

The consensus algorithm adopts the Delegated Proof of Stake (DPoS) mechanism. Under this mechanism, LUNA token holders can mortgage their tokens to a verification node to increase the weight of the verification node in the consensus process. In this way, LUNA token holders can participate in network governance and consensus, and share the rewards obtained by validators.

e. Incentive mechanism: The Terra consensus algorithm has designed an incentive mechanism to reward validators and stakers. Verification nodes obtain transaction fees and block rewards by verifying transactions and generating blocks. The tokens that LUNA token holders mortgage to the verification node can share the rewards obtained by the verification node in proportion, and also share the risk of the verification node. In addition, verification nodes need to maintain good network performance and integrity, otherwise they may be punished due to malicious behavior or being offline for a long time, and lose the mortgaged LUNA tokens.

f. Adaptability: The Tendermint consensus algorithm has good adaptability and can be easily integrated with other blockchain platforms. This allows Terra to achieve cross-chain interoperability with mainstream blockchains such as Ethereum and Binance Smart Chain, providing users with a wider range of decentralized financial services.

In short, the Terra protocol builds a decentralized financial platform through components such as stable coins, LUNA tokens, governance, and smart contracts. Terra uses a Tendermint-based Byzantine fault-tolerant consensus algorithm to ensure high performance, security and decentralization of the network. Through the Delegated Proof of Stake (DPoS) mechanism, Terra encourages LUNA token holders to participate in network governance and consensus, and jointly maintain the stability and development of the Terra ecosystem.

Please explain the Terra stablecoin (UST) introduction in detail

Terra Stablecoin (UST, TerraUSD) is a decentralized stablecoin in the Terra ecosystem, whose value is anchored in US dollars (1 UST = 1 USD). As the most important stablecoin in the Terra ecosystem, UST aims to provide stable value storage and means of payment for global users. The following is a detailed introduction about the Terra stablecoin (UST):

1. Stability Mechanism: The value stability of UST is maintained by LUNA, another token of the Terra ecosystem. When the market price of UST deviates from the anchor value, LUNA will adjust the supply of UST through the exchange with UST to maintain the stability of the value of UST. Specifically, if the UST price is higher than $1, users can use LUNA to mint UST at a price of $1, thereby increasing the supply of UST and reducing its market price. Conversely, if the UST price is lower than $1, users can use UST to buy LUNA for $1, thereby reducing the supply of UST and increasing its market price.
2. Transparency and security: As a decentralized stablecoin, UST’s minting and burning process is completely transparent and not controlled by any centralized organization. In addition, the Terra ecosystem has taken various measures (such as smart contract audits, bug bounty programs, etc.) to improve the security and reliability of UST.
3. Application scenarios: UST is widely used in various scenarios in the Terra ecosystem, such as: a. Cross-border payment and remittance: UST can be used to achieve fast and low-cost global remittance, especially in cross-border payment scenarios. b. Decentralized Finance (DeFi): Users can conduct various financial activities through UST, such as earning interest on deposits, lending, investing in synthetic assets, etc. c. E-commerce and payment: Through the Chai payment application, users can use UST for shopping and payment at offline and online merchants. d. Asset exchange: Users can easily exchange UST for other stablecoins or cryptocurrencies in the Terra ecosystem.
4. Cross-chain interoperability: Terra has achieved cross-chain interoperability with other mainstream blockchain platforms (such as Ethereum, Binance Smart Chain, etc.), allowing UST to be transferred and used between different blockchain platforms. This brings a wider range of application scenarios and user groups to UST

please continue

5. Tax Mechanism: The handling fees generated by transactions and activities in the Terra system will be converted into a mechanism called taxation. These taxes burn a portion of LUNA tokens, reducing the total supply of LUNA. This design helps maintain the scarcity of LUNA tokens and creates value for LUNA token holders.
6. Liquidity: As the core stablecoin of the Terra ecosystem, UST has received extensive market support. In many mainstream cryptocurrency exchanges (such as Binance, Huobi, Coinbase, etc.) and decentralized exchanges (such as Uniswap, Curve, etc.), UST has good liquidity, which is convenient for users to exchange and trade.
7. Community support: UST has been supported by a huge community, including developers, investors, users and other participants. As the Terra ecosystem continues to grow, the application scenarios and user base of UST will also continue to expand, further enhancing its status and influence as a stable currency.
8. Regulatory Compliance: The Terra team is constantly working to ensure that UST complies with regulatory requirements around the world. For example, Terra maintains close communication with governments, regulators, and financial institutions of various countries to ensure the legal circulation of UST within the legal currency systems of various countries.

In short, Terra Stablecoin (UST), as the core stablecoin of the Terra ecosystem, has the characteristics of stability, transparency, security, diverse application scenarios and cross-chain interoperability. Through fluctuations in the value of LUNA tokens, UST can maintain its value stability and provide convenient means of payment and value storage tools for global users. As the Terra ecosystem continues to grow, UST is expected to gain wider adoption and recognition around the world.

Please explain in detail the roles and requirements of validator nodes

In the blockchain network, validator nodes (Validator Nodes) play a vital role. They are responsible for verifying and confirming transactions and maintaining the security and stability of the network. Under the Proof of Stake (PoS) mechanism, validator nodes participate in the consensus process by holding and staking tokens.

The main roles and responsibilities of a validator node are as follows:

1. Block generation: The validator node is responsible for creating new blocks according to the rules of the consensus mechanism, and packaging the confirmed transactions into these blocks.
2. Validate transactions: Validator nodes need to validate transactions in the network, make sure they comply with the protocol, and ensure that the signatures of the transactions are valid.
3. Consensus: Under the PoS mechanism, validator nodes participate in the consensus process by mortgaging tokens. Validator nodes need to vote to confirm the blocks generated by other validators and reach a consensus. Voting weight is usually proportional to the amount of tokens staked by a validator.
4. Network Security: Validator nodes need to ensure the security and integrity of the network and prevent malicious behaviors such as double payment and replay attacks.
5. Governance: Validator nodes play a key role in the governance process of the blockchain network. They can vote on important matters such as network upgrades and parameter adjustments.

Please explain in detail how to become a validator on the Terra network

To become a validator on the Terra network, you need to follow these steps:

1. Prepare the hardware and network environment: Make sure you have sufficient hardware resources (such as a high-performance CPU, sufficient memory, and a large amount of storage space) and a stable network connection. Validator nodes need to have high availability and low latency.
2. Build a Terra full node: Follow the aforementioned tutorial to build and run a Terra full node. Make sure the nodes can sync blocks properly and keep up to date.
3. Create Authenticator Wallet: Create a new wallet using Terra Station and make sure you have backed up your seed phrase. You will use this wallet as the operating account for the validator.
4. Top up LUNA to the validator wallet: Transfer sufficient amount of LUNA tokens to the validator wallet to meet the minimum collateral requirement (usually at least 1000 LUNA is required, but the exact amount may vary with market conditions).
5. Generate a validator key: Run the following command to generate a validator key: sqlCopy code terrad tendermint show-validator This will generate a public key for consensus. Keep this public key safe, as you will need it when creating your authenticator.
6. Create a validator: Make sure your full node has been synchronized to the latest block, and then run the following command to create a validator: scssCopy code terrad tx staking create-validator \ --amount=<amount-of-luna-to-stake> \ --pubkey=<your-validator-public-key> \ --moniker=<your-validator-name> \ --chain-id=<terra-chain-id> \ --commission-rate=<commission-rate> \ --commission-max-rate=<commission-max-rate> \ --commission-max-change-rate=<commission-max-change-rate> \ --min-self-delegation=<minimum-self-delegation> \ --gas=auto \ --gas-adjustment=<gas-adjustment> \ --gas-prices=<gas-prices> \ --from=<your-validator-wallet> \ --node=<your-full-node-rpc> \ --broadcast-mode=block Please replace the variables in the angle brackets according to the actual situation. For example, <amount-of-luna-to-stake>replace with the amount of LUNA you want to stake, and <your-validator-public-key>replace with the validator public key you generated in the previous step.
7. Waiting to be selected as a validator: After creating a validator, you need to wait to be entered into the validator collection. Validators are ranked based on the total amount of LUNA staked, including your own stake and LUNA delegated to you by others. The Terra network has a limited number of validators, so you will need to compete to become a validator. Before becoming a validator, your node is considered a validator candidate.

8. Securing your nodes: As a validator, you need to protect your nodes from attacks and potential threats. Make sure to configure firewalls, intrusion detection systems (IDS), and other security measures. You might also consider using a hardware security module (HSM) to store keys for additional security.
9. Build and maintain community trust: maintain active engagement with the community, sharing information about your validator node operations and governance decisions. This helps build trust and attracts more users to entrust tokens to you. You can increase your visibility and credibility by participating in community forums, creating blog posts, or publishing real-time operational data.
10. Monitor node status: Regularly check the running status of the node to ensure that it is always online and in sync with the network. You can use various monitoring tools such as Prometheus and Grafana to view the performance metrics of the nodes in real time.
11. Participate in governance: As a validator, you are responsible for participating in the governance of the Terra network. Actively express opinions and vote on key issues such as proposals and parameter adjustments to ensure the long-term development and prosperity of the network.

By following the steps above, you can successfully become a validator on the Terra network. As a validator, you will take responsibility for maintaining the security and stability of the network, and earn income from validator rewards and commissions from delegators. At the same time, actively participating in governance and community building will help you build a reputation in the Terra ecosystem and attract more users to delegate tokens to you.

Please explain in detail the pledge and voting mechanism

In a blockchain network based on Proof of Stake (PoS), pledge and voting mechanisms are crucial to maintaining network security and distributing rights and interests. The following is a detailed explanation of the pledge and voting mechanism:

1. Staking: Staking is the act of users locking (mortgaging) a certain amount of tokens in the PoS mechanism to participate in the consensus process. By staking tokens, users can earn a portion of network rewards, such as block rewards and transaction fees, while providing security for the network.

During the staking process, users can choose to delegate tokens to validator nodes. Validator nodes are responsible for validating transactions, creating new blocks, and maintaining network security. Validators typically charge a percentage of commission in return for providing their services.

2. Voting: The voting mechanism is the process of reaching consensus on new blocks among validator nodes in the PoS network. Validator nodes are given voting weight based on the amount of tokens they have staked (and the amount of tokens other users have delegated to them). The higher the voting weight, the more influence the validator has in the consensus process.

Validator nodes are required to vote for candidate blocks produced by other validators. When a majority of validator nodes reaches consensus on a candidate block, that block is added to the blockchain. The voting process helps ensure the security and consistency of the blockchain.

3. Rewards and penalties: In the PoS mechanism, users who stake tokens (including validators and delegators) can get network rewards. Rewards are usually distributed in the form of tokens, derived from block rewards and transaction fees. The distribution ratio of the reward depends on the validator’s total amount of collateral and the commission ratio it charges.

However, validator nodes may face penalties if they fail to perform their duties (eg, double-sign or go offline for an extended period of time). Penalties usually take the form of forfeiture of some or all of the mortgaged assets (known as “slashing” or “slashing”). Slashed validator nodes may lose their place in the network, as well as the users who delegated to them.

In short, the pledge and voting mechanism is the core component of the PoS blockchain network. They provide security and stability to the network and incentivize users to participate in the consensus process. Users who pledge tokens can get rewards, but they also need to bear some

certain risks, including being curtailed or being affected by market volatility. The voting mechanism ensures the security and consistency of the network and ensures that all validator nodes follow common rules. In the PoS mechanism, the interests of validator nodes and users are highly related, so they all have the motivation to maintain the stability and development of the network.

In the Terra network, the pledge token is LUNA, and users can pledge it to any validator node. Validators can set their own commission ratio, but it is generally recommended to choose a validator with a lower commission to obtain a higher yield. The delegator can also delegate to the validator through the delegation service to obtain better mortgage returns.

The voting mechanism adopts the Tendermint consensus algorithm, which uses the way of taking turns to generate blocks to ensure the security and consistency of the network. In Tendermint, validator nodes jointly maintain the network state by taking turns to generate blocks. Each validator node takes turns generating new blocks according to its voting weight. Other validator nodes vote on the block, ensuring it is widely accepted.

In the Terra network, validators can set their own commission rate, but cannot exceed the maximum limit. If a validator fails to produce a block on time or fails to perform its duties, it will be punished by slashing or downgrading. Delegators also need to pay attention to the performance of validators to ensure that their collateral assets are maximized.

In short, the pledge and voting mechanism is the core component of the PoS blockchain network. In the Terra network, the pledged token is LUNA, and users can choose to delegate to validator nodes to get rewards. The voting mechanism adopts the Tendermint consensus algorithm to ensure the security and consistency of the network. Both validators and delegators need to be mindful of risks and evaluate validator performance to ensure maximum returns.
