Thread 8 of 10, over the past couple of months we have talked and highlighted the various threads written and reported by PlatON with regards to token confidentiality and privacy report, from what it entails to why the need for token confidentiality and it's various technical approaches.
Thread 8 of 10, like the previous threads from 4 to 7 also entails more technical approaches towards token confidentiality and today's writeup is on Solution Deep Dive — TEE & Canton.
Before diving further, what does Tee and Canton entail?
TEE — private contract and asset logic in a trusted execution environment
Canton — data minimization for institutional finance; participants only see relevant data
Based on previous writeup where we highlighted various approaches are somewhat thesame and opposite in terms of EVM compatibility and not, on today's writeup, Tee is a bit more closer to EVM compatibility as it is based on privacy contract where it is handled in an in-house environment from execution to decrypting. Whereas, Canton is a based on the need to know approach with data compacted to it's minimum variable.
Why Tee or rather it's major takeaways?
✅ Performance and developer experience usually better than pure cryptographic approaches
✅ Easier to align with EVM, Solidity, and existing business logic
✅ Suitable for quickly building confidential ERC-20, private order books, permission fields, and risk-control logic
Depends on hardware security and remote attestation
Requires handling TEE node election, key management, and fault recovery
For high-value financial assets, additional governance and audit mechanisms are required.
Canton and it's major takeaways?
✅Very close to the compliance and privacy requirements of financial institutions
✅ Emphasizes permission boundaries, auditability, and participant visibility
✅ Suitable for bonds, RWAs, settlement, and interbank business
Not an open EVM public-chain path
Application ecosystem and development model differ significantly from ERC-20
More suitable as an institutional architecture reference than as a direct technology stack for existing public chains.
The thread further gives recommendations on when to apply both in various scenarios and you can read it's entirety on PlatON official X page
That ends thread 8 and catch up with thread 9 on next writeup, do have fun and stay bless.
