Enhancing blockchain security: Combining Intel SGX and zk-SNARKs

Blockchain, the backbone of digital currencies and decentralized applications (dapps), has grown in popularity and adoption over the past few years. However, along with this growth comes a pressing need for enhanced security measures for protection against breaches and attacks. 

As the blockchain landscape evolves, the complexity of its security demands also increases. In many cases, networks that didn’t prioritize security have been breached, highlighting the significance of employing the best security approaches.

Understanding blockchain security

Blockchain security is multifaceted, with various methods employed to keep networks safe. Some of these approaches are more robust than others. However, the best current system often combines several technologies.

One such combination uses programmable protection technology based on Intel SGX alongside cryptographic protection technology, such as zk-SNARKs.

Intel SGX, a software guard extension, offers a powerful hardware-based encryption solution to protect sensitive data by creating secure enclaves within the processor. 

This technology has been shown to provide strong encryption capabilities, safeguarding data from potential attackers. 

However, when combined with zk-SNARKs, a cryptographic technique that allows one party to prove ownership of information without revealing it, the security platform becomes even more robust.

Exploring new frontiers and opportunities

Among the few platforms using this security combination is Swisstronik, an identity-based hybrid blockchain for web3 and traditional companies to build know-your-customer (KYC), anti-money laundering (AML), and data protection regulation (DPR) compliant products. The mainnet also maintains a balance between privacy, accountability, and decentralization. Swisstronik’s technology stack is built on Cosmos SDK and is Ethereum-compatible for smooth integration with other networks.

Swisstronik achieves this by focusing on three key areas:

• Developing an automated network of top KYC and AML providers, regulatory bodies, and other compliance partners per jurisdiction for easy yet compliant cross-border operation of clients’ Swisstronik-based applications.
• Facilitating DPR compliance by allowing clients to keep sensitive data private and hidden via a unique combination of data protection methods in programmable protection technology based on Intel SGX and cryptographic protection technology based on zk-SNARKs.
• Providing a comprehensive set of customizable non-custodial utilities, such as decentralized identity (DID), zero-knowledge (ZK) transactions, and decentralized messenger services. Swisstronik focuses on blockchain interoperability and scalability to enable businesses to deploy advanced applications with minimum costs rapidly.

Swisstronik’s approach to security demonstrates the power of combining multiple advanced security technologies to create a comprehensive solution. 

Ushering a new era of blockchain security

By employing programmable protection based on Intel SGX and cryptographic protection based on zk-SNARKs, the platform ensures high security for sensitive data while allowing for regulatory compliance and interoperability across various jurisdictions.

It becomes increasingly clear that more than one approach to security is needed. Superior blockchain security approaches must combine techniques for a more robust, comprehensive solution. Swisstronik’s use of Intel SGX and zk-SNARKs is a prime example of how a synergistic approach to security can be more effective than relying on a single technology.

Platforms and networks must prioritize the security of their systems and data. With the combination of Intel SGX, zk-SNARKs, and related techniques, a new standard in blockchain security can be set, ushering in a safer, more secure future for solutions.
