Exploring the Qitmeer Cross-Chain Bridge: Analyzing Transaction Differences and Common Misconceptions (2)
After a brief introduction to the previous article, we believe you now have a basic understanding of the Qitmeer Cross-Chain Bridge and its operational principles. This article will delve deeper into the key details of the cross-chain bridge.
Different Types of Cross-Chain Bridges
Cross-chain bridges are typically categorized into two types: centralized bridges, and decentralized bridges.
The main difference between these two types lies in who controls the tokens used to create bridged assets, involving trust in third parties or code.

Centralized Bridges
Migrating cryptographic assets to another blockchain means relinquishing control over them and entrusting the secure management of your assets to others.
While bridges based on centralized trust may be fast and cost-effective for transferring small amounts of cryptocurrency, overall, this approach poses certain risks to the security of your assets.
Decentralized Bridges
For decentralized bridges, you still need to delegate control of your cryptographic assets. However, this trust is based on code execution and relies on the liquidity provided by the cross-chain bridge for asset transfers.
Transaction Discrepancies and Common Misconceptions
The cross-chain bridge doesn’t directly transfer assets from the Qitmeer blockchain to another blockchain. Instead, it plays the role of a liquidity intermediary.
- It receives your assets on one side and transfers the corresponding on-chain assets to you on the other side.
This process is tracked by smart contracts to ensure each cross-chain interaction occurs reliably, thereby ensuring the security of assets.
Differences Between Cross-Chain Transactions and Transfer Transactions
- Common transfer transactions enable users to send and receive assets within the same blockchain network.
- Cross-chain transactions allow users to move assets from one blockchain to another. Never send assets to another blockchain without verifying network information.
Common Misconceptions
New users of Qitmeer often make a costly mistake — Send Qitmeer USDT assets to another network without going through the cross-chain operation, resulting in the loss of assets.
- As the QNG network is a cross-chain container layer compatible with EVM in the Qitmeer network，all EVM-compatible chains use blockchain account addresses starting with 0x.
When users fail to carefully distinguish networks, there’s a risk of mistakenly considering assets that require “cross-chain” conversion as “traditional” transactions. This may lead to sending USDT assets to the wrong blockchain network. Stay vigilant to avoid this common mistake.
The Security Mechanism of Cross-Chain Bridges
Cross-chain bridges are key to ensuring effective communication and asset transfer between different blockchains, so their security is crucial.
The smart contracts utilized by the Qitmeer Cross-Chain Bridge undergo rigorous security reviews and testing. With a sufficient number of validating nodes, the system’s security is well-maintained, ensuring there are no vulnerabilities during the cross-chain asset transfer process. This makes cross-chain transactions more trustworthy and reliable.
