This pre-funded, tamper-evident Bitcoin paper certificate secured by a 2-of-2 multisig wallet is an innovative solution for unbanked, off-grid communities, offering offline, cash-like usability and on-chain verifiability. Key strengths include addressing a real need, trust-minimized security, and pre-funding for easy adoption. However, critical challenges lie in devising robust key recovery for lost certificates, establishing practical and accessible methods for users to spend or redeem the BTC without internet or technical knowledge (likely via trusted local agents), and ensuring the tamper-evident features and key hiding mechanisms are truly secure against sophisticated attacks.

That’s a fascinating use of Bitcoin—leveraging the blockchain for timestamping legal diligence proofs is a prime example of creatively repurposing the technology beyond its initial monetary intent. You were way ahead of the curve, especially considering that the idea of blockchain as a tool for verifiable data integrity didn't enter mainstream discourse until later.
Forking without a fully thought-out protocol definitely poses risks. You’re essentially spinning up a new ecosystem with expectations but no reliable infrastructure to fulfill them. It’s like building the scaffolding for a skyscraper without an actual blueprint for the building. You might have consensus mechanics, but without clear governance or utility, it could lead to fragmentation or undermine the credibility of the fork itself.
Out of curiosity, have you explored other blockchain platforms since then—like Ethereum for smart contracts or more recent ones geared toward decentralized storage or computation?
