Bitcoin Notes

UTXO

UTXO stands for Unspent Transaction Output. It represents electronic money, as ownership of UTXO means you have money.

About Public and Private Key Pairs

A public-key cipher has a pair of keys for sending messages. Both the keys in the pair belong to the person receiving the message. One key is a public key and may be given to anybody. The other key is a private key and is kept secret by the owner. A sender can encrypt a message using the public key and once encrypted, only the receiver with the private key is able to decrypt it.

A document's digital signature is the result of applying a hash function to the document.

Key tampering is a major security weakness with public-key cryptography.

Storing Bitcoins Locally

Technically you don't store bitcoins anywhere, what you store are the keys used to access your public bitcoin addresses and sign transactions. This information is stored in a Bitcoin wallet.

Types of Bitcoin Wallet

Online wallet - This is a service provided to you by another party, and stores your private keys online. This has the convenience factor of being a service provided to you, i.e. you don't have to take care of all the technical aspects of running a Bitcoin wallet yourself. Being online, it also offers convenient access. However, technically someone else is in charge of your private keys, which means you aren't in ultimate control of your Bitcoins.
