Confidentiality Trusted computing platforms can be used to provide a mechanism by which confidentiality of transaction can be achieved on a blockchain, for example, by using Intel Software Guard Extension (SGX), which allows code to be run in a hardware-protected environment called an enclave.
Once the code runs successfully in the isolated enclave, it can produce a proof called a quote that is attestable by Intel’s cloud servers.
A Complete Guide to Understanding This Blockchain Concept
However, it is a concern that trusting Intel will result in some level of centralization and is not in line with the true spirit of blockchain technology.
Nevertheless, this solution has its merits and, in reality, many platforms already use Intel chips anyway, therefore trusting Intel may be acceptable by some in some cases.
If this technology is applied on smart contracts then, once a node has executed the smart contract, it can produce the quote as a proof of correct and successful execution and other nodes will only have to verify it.
This idea can be further extended by using any Trusted Execution Environment (TEE) which can provide the same functionality as an enclave and is available even on mobile devices with Near Field Communication (NFC) and a secure element.
Why This Matters for Blockchain Technology
Understanding Usage of hardware to provide is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
