The text discusses the basics of blockchain technology, focusing on BTC and ETH. It highlights the advantages of ETH over BTC, such as faster transaction speeds and support for smart contracts. It also mentions the creation of ETC after a hard fork due to an attack on the ETH network. Additionally, it mentions the use of the MetaMask wallet for storing and trading ETH, as well as learning Solidity for programming smart contracts.

1. Understanding Blockchain Technology in 2 Hours#

  1. BTC, ETH
    BTC Distributed ledger, decentralized, transactions cannot be tampered with
    ETH Advantages compared to BTC: significant increase in transaction speed, support for smart contracts (automatically executed according to code rules), while increasing transaction speed, the main chain cannot merge the specific block collected by multiple miners, hence the introduction of the ghost consensus mechanism, which evenly distributes rewards in proportions of 7/8 and 1/8.
  2. ETH was attacked on-chain, resulting in the birth of ETC after a hard fork. The soft fork was terminated due to version costs for fees and fuel, hence the adoption of a hard fork.
  3. ETH uses the web plugin MetaMask wallet for storing and trading ETH, using a 12-word mnemonic for storage. Tokens and mnemonics can both be used for account login, transfers, and operations.
  4. Learning related to Solidity: 1. Using the Remix environment 2. Using relevant basic variables.
