📡【Technical Anti-Fraud Revelation】Why can customized fake nodes create assets out of nothing?

Understand the underlying logic of blockchain "smoke and mirrors" in one article!

💻 Technical Breakdown: The "Parallel Universe" Scam of Fake Nodes

🔍Part 1: Balance Display Mechanism (What you see may not be real)

When you enter an address in your wallet:

The wallet sends a query request to the connected RPC node

The node returns the account status data for that address

The wallet parses the data to display the balance

❗Key Vulnerability: Nodes can selectively return data!

Malicious nodes are like a "filter camera", they can:

✅ Forge mainnet token balances (USDT/BTC, etc.)

✅ Tamper with smart contract information (show fake staking returns)

✅ Construct virtual transaction records (forge transfer receipts)

🌐Part 2: Three Forms of Fake Nodes

❶ Testnet Nodes (Beginner Trap)

• Characteristics: Network ID different from the mainnet (ETH mainnet=1, testnet=5)

• Scam: Use testnet USDT to impersonate mainnet assets (value is 0)

❷ Private Chain Fork Nodes (Advanced Scam)

• Technical Principle: Create a mirror of the mainnet

• Fatal Characteristic: Completely replicates the mainnet environment but operates independently

• Recognition Difficulty: Network ID/Chain ID exactly the same as the mainnet!

❸ Data Hijacking Nodes (Hacker Tactics)

• Operating Method: Man-in-the-middle attack alters returned data

💥Part 3: Why can't fake coins be transferred?

When you want to transfer the "received" USDT:

The transaction request is sent to the malicious node

The node packages the transaction on a private chain (creating a false impression of success)

Actual mainnet nodes never received this transaction!

When switching to the official node, the transaction record instantly disappears

🔬Technical Essence: The "Parallel Universe" Phenomenon in Blockchain

• Real Nodes: Connect to a global consensus network (thousands of nodes synchronize verification)

• Fake Nodes: Operate on a "island server" set up by scammers

• Core Difference: Whether it is recognized by blockchain explorers (like Etherscan)

✅ Three Key Elements for Node Verification

Network ID Verification (eth_chainId interface)

Cross-Verification by Blockchain Explorer (balance/transaction dual-check)

Smart Contract Address Traceability (through the verify contract feature)

Teaches you how to identify the authenticity of nodes using developer tools!

📌Remember the Golden Rule:

On-chain assets are based on blockchain explorers

Wallet balances are merely "reference answers" provided by nodes.
