If you mean storing your private key on Bitcoin's blockchain, technically it's possible by storing encrypted private key, seed, mnemonic or wallet file on Bitcoin's blockchain with lots of OP_RETURN.
You also can replace it with any P2P protocol such as IPFS or BitTorrent
So much so that no one really knows what he's talking about. Everyone is trying to comment but it is unclear what interpretation.
I think, he need to edit and give some details for us that post.
Hi All,
If someone already opened this topic please give me link. If not, is it possible? I mean it is easier to access it right than a cold storage?
