What does BSM mean in UNCLASSIFIED

Bitcoin Signed Message (BSM) is an authentication system used in the Bitcoin blockchain to certify ownership of a particular address and message. It's a form of digital signature that allows users to send a message with an associated proof that the user had access to the private key associated with that address. This proof is what verifies the integrity of the message, preventing anyone from tampering with it.

In order to create a BSM, you have to use a program such as Electrum or Mycelium, which will store your wallet secret keys securely. Then, you can enter your message within the program and sign it with your private key (which will be hashed into a digital signature). Once it's signed, you can then broadcast your signed message via an online service or directly in the Bitcoin network if you wish.

Once your message is signed, it becomes part of the distributed ledger known as the blockchain. Anyone who wants to check its authenticity can use this signature for verification purposes. This helps ensure no one has tampered with it in any way since its creation.

Yes, you can easily verify someone else's BSM using publicly available tools such as Blockcypher or OpenTimestamps. All you need to do is enter their public key and the original text they've sent and these tools will generate a unique verification code based on their signature - allowing you to confirm whether or not it matches what was originally sent out by them.

No, there are no fees involved in signing for messages using BSM authentication system; all that’s required is an internet connection and some knowledge of how to operate programs like Electrum or Mycelium.

Yes, BSM authentication process provides quite secure guarantee that no malicious actor could tamper or modify your messages - provided that only you know your own private key! As long as this is kept confidential and stored securely, nobody but yourself can sign off on transactions made using this system.

Signing for messages using BSM helps protect both parties involved in transactions against fraud - allowing them to confidently send funds without worrying about potential theft or manipulation of funds by malicious third-parties. Additionally, BSM also serves as proof of ownership - guaranteeing whoever owns a certain address really did initiate whatever transaction they claim they did!

After sending out your BSM-signed message successfully in the blockchain network, it'll generate a confirmation code containing either 6 characters (for addresses starting with 3) or 7 characters (for addresses starting with 1). You'll need this code when verifying its authenticity later on.

Generally speaking almost any type of data including plain text document files (.txt), JSON objects and even binary documents like images (.jpg) are all eligible for signing with this authentication system.
