The trap of "permanent storage" is the stuffing mindset. Blockchain is not a dumpster. If everything continues to be forced "on-chain" in a cumbersome manner, the system will self-destruct due to exorbitant gas costs and privacy leaks. It is from the failures of carrying raw data that Hybrid Attestations of Sign Protocol emerged as an inevitable liberation.
In essence, I see this as a Filter Layer: It separates "Proof" from "Raw Data". Instead of bringing the entire warehouse on-chain, it leaves behind a lightweight cryptographic fingerprint (CID/Hash). Its role is to ensure undeniable authenticity without congesting the infrastructure. The breakthrough lies in the mindset: verifying everything without needing to own (or expose) the raw data.
You have Tamper-proof but do not have to pay an unreasonable price for every byte of data. Hybrid Attestations transform discrete data into a powerful Evidence Overlay layer. Thanks to ZK-proofs, the system allows Selective Disclosure - proving the data is correct without exposing sensitive "guts". Trust can now be "carried" everywhere (Omni-chain) from Ethereum, Solana to TON.
The builder community is using the SDK/API of S.I.G.N. to connect with real-world systems like Singpass. We no longer waste time "re-checking" outdated truths, but are operating a reliable, lightweight, and extremely Scalable infrastructure. Architecturally, it is distinctly superior. As for how it performs at scale, my backers and I will wait to see how S.I.G.N. executes it 😊
