- A bitcoin wallet only holds your private keys, i.e. no funds. The balance of your funds and the records of all your confirmed transactions live on the blockchain forever. The private keys, in a bitcoin wallet, are used to create and sign new transactions, that once signed (yet unconfirmed) can be broadcasted to the network, in order to be verified by the nodes and confirmed by a miner. And to read/query the blockchain in order to check your funds/balance (spent & received funds).

A bitcoin wallet stores your private key, signs outgoing transactions with your private key and monitors incoming funds sent to your public key. It also adds up incoming UTXO’s (unspent transaction outputs, sent from other wallets) and subtracts sent funds from that total to calculate your balance.

- Describe in short what a bitcoin wallet does.
A bitcoin wallet stores the private key that provides access to your bitcoins on the blockchain. By providing the private key, the wallet is initiating a transaction and granting permission to the Blockchain network (signs the transaction) to withdraw funds from entries on the blockchain with that address. Finally, the wallet also receives communication from the blockchain confirming the withdrawal or deposit of funds from the blockchain and updates the database on the app to reflect the new balance.

In short a bitcoin wallet is a private key and its corresponding public key. A paper wallet effectively has no other information. A wallet on the network stores your keys but also usually has software included to perform functions like broadcasting transactions, generating new address and signing with your private key. Wallets connected to the network are referred to as “hot” wallets. A “cold” wallet is a device or paper wallet which stores your keys and is not connected to the network.

And even when you need to create and sign a transaction, the private key will not ever be revealed to you PC or internet. The hardware wallet signs the transaction in the device itself, and only sends the already signed transaction back to your pc. After that your PC will broadcast the transaction and the transaction will propagate throughout the network.

Describe in short what a bitcoin wallet does.
A Bitcoin wallet holds a public and private key. You have no coins in your wallet. The nodes communicate together, determining your unspent Bitcoin, based on the blockchain ledger. A Bitcoin wallet can send and receive transactions within the blockchain network. One thing to note is, there are different types of wallets. When selecting a wallet, you should hold your own public and private key, otherwise the funds technically do not belong to you.
