I love Bitcoin. I love how it's elegant, functional, philosophical, and radical. Unfortunately, for folks not steeped in cypherpunk ideology and network security, bitcoins are hard to understand, hard to purchase, and hard to keep safe

Trusted timestamping and proof of existence of documents have been numerously proposed on the Blockchain. Through cryptographic protocols and the irreversibility of the blockchain, document cryptographic hash inserted into the blockchain provides suf
Direct answers to your questions: I) Technically this is not too difficult. Looping through every new transaction on each received new block does not take too many resources and checking each transaction against 100,000 public keys is no problem at a
BIP38 wallets are password encrypted private keys stored on paper, and you can store the secret random password in a separate place. You can also do multisig with these wallets, I believe, so this has the potential to be much more secure. For example
Does such possibility exist in NXT ? Unlike BTC, new NXT account has to send at least one outgoing transaction to become fully initialized by the network, otherwise collisions may spoil it. Sending money to that account is not sufficient for initiali
Not completely what you asked for, but if you have a significant amount of money in bitcoin it makes sense to store them on a hardware wallet like trezor, ledger, . .
