# On-chain Firewall

## Introduction to On-Chain Firewall

GoPlus introduces a groundbreaking security feature: the On-Chain Firewall. This innovative solution provides real-time transaction protection on the blockchain, automatically blocking malicious and dangerous transactions that could harm users. Unlike traditional pre-transaction warnings, our On-Chain Firewall implements seamless risk control and blocking capabilities, significantly enhancing the security of the blockchain environment.

## Key Features of On-Chain Firewall

* Real-time Protection: Monitors and analyzes transactions in real-time as they occur on the blockchain.
* Automatic Blocking: Instantly stops malicious or high-risk transactions before they can cause harm.
* Seamless User Experience: Operates invisibly in the background, providing security without disrupting the user experience.

## Implementation Strategy

To provide each blockchain with native risk control and security capabilities, GoPlus implements the security service through a three-step process:

#### 1. GoPlus Intelligence Integration

* Provide GoPlus Intelligence support tailored for the specific blockchain.
* Offer APIs and SDKs to wallets and various projects on the chain.
* Enable developers to easily integrate robust security features into their applications.
* Deliver real-time security insights and risk assessments for transactions and smart contract interactions.

#### 2. Secure RPC Service Provision

* Deploy secure, native RPC nodes for the blockchain.
* Allow users to directly utilize these secure RPC endpoints for enhanced protection.
* Implement additional security layers at the RPC level to filter and analyze transactions.
* Provide a trusted infrastructure layer for secure blockchain interactions.

#### 3. Native Blockchain Integration

* Collaborate with blockchain projects to integrate a User Security Module.
* Implement an additional security layer directly into the blockchain's architecture.
* Enable native risk control capabilities at the chain level.
* Ensure that security checks are performed as an inherent part of the transaction validation process.

## Conclusion

The On-Chain Firewall represents a significant leap forward in blockchain security. By providing real-time, seamless protection at multiple levels of the blockchain stack, GoPlus is setting a new standard for security in the decentralized world. As we continue to expand and refine this technology, we envision a blockchain ecosystem where users can transact and interact with confidence, knowing that advanced security measures are working tirelessly to protect their assets and interests.
