Could you build this?
No Deploying self-custodial Lightning Network nodes inside Trusted Execution Environments (TEEs) involves complex cryptography, confidential computing hardware enclaves, and Lightning protocol (BOLT) channel state management where any bug risks permanent fund loss. This requires specialized cryptographic, hardware security, and Bitcoin infrastructure engineering.
What it would actually take: The architecture comprises AMD SEV-SNP or AWS Nitro Enclaves running an isolated Rust Lightning Development Kit (LDK) node, backed by remote attestation protocols and replicated channel-state storage. The hardest challenges are ensuring zero-latency channel updates while preventing stale-state broadcast (punishment transactions) and securely persisting encrypted key state across enclave lifecycles without human intervention. This requires specialized cryptographic systems engineers and Bitcoin Lightning protocol experts.
Discussion
3 comments analyzed.
Competitors mentioned: Breez mobile wallet, Phoenix mobile wallet, Custodial wallets
Concerns raised: Performance extremely slow (1000x slower for getting current time), Memory bottleneck storing entire Lightning Network graph, Lightning reliability historically problematic, Offline receive failures in mobile wallets
