- Would It Be Technically Possible To Delete Old Blocks From A Blockchain . . .
From what I understand, a cryptocurrency mine needs to store a copy of the entire blockchain in order to be able verify transactions, which is why most wallet owners are not miners The more centra
- sha 256 - How to deal with collisions in Bitcoin addresses . . .
Well, I know that occurrences of such collisions will happen with a very low probability And, this is fine for me But, at least, I would have expected that, during the creation of a BTC address, one would check that the current address does not appear in the blockchain But, still, this is not enough as the creation should occurs in a decentralized manner, so two addresses in collision
- Public key decryption? - Cryptography Stack Exchange
In the article How Does the Blockchain Work? the writer makes the following statements: Since only you should be able to spend your bitcoins, each wallet is protected by a special cryptographic method that uses a unique pair of distinct but connected keys: a private and a public key
- Is it bad to expose the public key? - Cryptography Stack Exchange
Yes, hypothetical quantum computers usable for cryptanalysis would allow an adversary to attack a known public key of the kind we use now (and in the blockchain) On the other hand Currently, available quantum computers are less useful for cryptanalysis than available lightsabers are to break into a bank's safe room
- Using a blockchain for secure communication - Cryptography Stack Exchange
I've recently heard of the idea of using a blockchain for secure communication No details were given so it's a little hard for me to say that it can't be done But as far as I know: Secure communi
- Downsides of not using deterministic ECDSA signatures for blockchain . . .
I've noticed that in many Bitcoin wallet implementations, as well as other blockchains, deterministic ECDSA signatures are being used (generally based on RFC 6979) There seems to be some benefits
- Whats the purpose of key-rotation? - Cryptography Stack Exchange
Key rotation doesn't decrease the risk of keys being breached It mainly limits the amount of data encrypted under a certain key, so one may say it's done to so if a future key gets breached past comms are safe (r)
- Zencash uses your passphrase to identify AND unlock a wallet - how is . . .
Well, if you have a deterministic procedure to generate a private key (s) from a master secret, then you can create the wallet and subsequently re-create the wallet whenever you log back in, just with the difference that the server has the blockchain for your transactions
- aes - Does this PBKDF2-SHA1 payload hint at a cryptographic security . . .
Does it looks like “correct” PBKDF2-SHA1 or does AAAAAA… indicate that something was broken? During the login attemp to blockchain info I get a response with a base64-encoded payload, that in fact authorizes my encrypted PBKDF2-SHA1 wallet I have had no success trying to decrypt this (original BCI server utils)
- 19 out of 24 words of BIP39 passphrase (brute-force last 5?)
I have managed to lose 5 words of my 24 word Ledger Nano S recovery phrase I have words 1-19 but I am missing words 20-24 I have significant holdings on the wallet so would very much like to reco
