How to change the size of a Bootstrap list?

Through its Turing-complete smart contracts, EVM virtual machines and Gas mechanisms, Ethereum has built a programmable blockchain platform beyond Bitcoin, supporting diversified application ecosystems such as DeFi and NFT; its core advantages include a rich DApp ecosystem, strong programmability, active developer community and cross-chain interoperability; it is currently implementing consensus transformation from PoW to PoS through the upgrade of Ethereum 2.0, introducing beacon chains, verifier mechanisms and punishment systems to improve energy efficiency, security and decentralization; in the future, it will rely on sharding technology to realize data sharding and parallel processing, greatly improving throughput; at the same time, Rollup technology has been widely used as a Layer 2 solution, Optimistic Rollup and ZK-Rollu

Blockchain is a distributed and decentralized digital ledger technology. Its core principles include: 1. Distributed ledger ensures that data is stored simultaneously on all nodes; 2. Encryption technology, linking blocks through hash values to ensure that data is not tampered with; 3. Consensus mechanisms, such as PoW or PoS, ensure that transactions are agreed between nodes; 4. Decentralization, eliminating single point of control, enhancing censorship resistance; 5. Smart contracts, protocols for automated execution. Cryptocurrencies are digital assets issued based on blockchain. The operation process is: 1. The user initiates transactions and signs digitally; 2. The transactions are broadcast to the network; 3. The miner or verifier verifies the validity of the transaction; 4. Multiple transactions are packaged into new blocks; 5. Confirm the new zone through consensus mechanism

ETH exchange USDC is more suitable for users who pursue liquidity and cross-platform compatibility, while redemption DAI is more suitable for users who participate in the DeFi and DAO ecosystem; 1. The centralized platform fee is 0.1%~0.2%, and the DEX commission depends on the Gas fee. The main network is about 3 to 6 US dollars, and Layer2 can be less than 0.1 US dollars; 2. In terms of account arrival speed, the centralized platform is almost real-time, with on-chain transactions on average 30 seconds to 2 minutes; 3. USDC trading pairs are richer and more liquid, DAI is highly adaptable in the DeFi protocol and the handling fee is slightly lower in some pools; 4. It is recommended to avoid peak network operations, and small redemption is preferred. DEX transactions pay attention to contract authorization security to ensure stablecoin withdrawal network compatibility. Both are in the handling fee.

In the field of digital currency, a full range of variables and opportunities, increasing the principal of 5,000 to 500,000 means that one hundred times the asset appreciation needs to be achieved. This is not a simple math game, but a comprehensive test involving cognition, strategy, mentality and execution. It requires participants not to rely solely on luck, but also to have keen market insight and extraordinary risk management capabilities.

Blockchain browser is a necessary tool for querying digital currency transaction information. It provides a visual interface for blockchain data, so that users can query transaction hash, block height, address balance and other information; its working principle includes data synchronization, parsing, indexing and user interface display; core functions cover querying transaction details, block information, address balance, token data and network status; when using it, you need to obtain TxID and select the corresponding blockchain browser such as Etherscan or Blockchain.com to search; query address information to view balance and transaction history by entering the address; mainstream browsers include Bitcoin's Blockchain.com, Ethereum's Etherscan.io, B

Bitcoin (BTC) is a digital asset created and run based on cryptography principles. It does not rely on specific central institutions, such as banks or governments, to issue and manage. Its concept was first proposed in 2008 by an individual or group named "Satoshi Nakamoto" in a paper titled "Bitcoin: A peer-to-peer electronic cash system."

Yes, SOL may explode again in 2025. 1) Technology upgrades such as Firedancer launch, which is expected to increase TPS to one million level; 2) New DePIN and AI narratives promote ecological development; 3) On-chain data continues to recover, TVL exceeds US$2 billion; 4) Institutional funds return combined with ETF expectations; 5) If fundamentals and market sentiment cooperate, the price is expected to hit US$250, but you need to be wary of the history of downtime, intensified competition and risk of token selling pressure. Investors should build positions in batches and combine on-chain data dynamic adjustment strategies. The final outbreak depends on the synergistic effect of technology implementation, ecological activity and capital resonance.

Stable coins are cryptocurrencies whose value is linked to stable assets such as the US dollar or gold. They aim to solve the problem of large price fluctuations in currencies such as Bitcoin. They achieve price stability through an anchoring mechanism and are mainly divided into three categories: 1. Stable coins with legal currency collateral, such as USDT and USDC, are supported by US dollar reserves, and users can exchange 1:1; 2. Stable coins with crypto assets collateral, such as DAI and crvUSD, are generated by over-collateralized digital assets such as Ethereum, and have decentralized characteristics; 3. Algorithmic stable coins, such as USDD, rely on algorithms to adjust supply and demand to maintain currency value, and have no direct asset collateral, and are at a high risk. The top 10 stablecoins currently ranked in market capitalization include: 1. USDT, the earliest and most liquid dollar stablecoins; 2. USDC, to comply with and
