It houses your crypto and is protected by the requirement for your personal key to enter or do any transaction. It can be a hardware wallet, a hosted wallet, even a wallet on paper. when it is used, it is verified by nodes collectively and any transaction made entered on the blockchain - ledger. A hosted wallet is a wallet that is managed by an agency/company like Coinbase for instance, which will house many customers coins in the wallet. You donāt want your personal key to ever be used on the internet as your crypto it could be jacked/hacked and disappeared. that is why a hardware wallet serves best as it has far higher security.

- That depends on the type of the wallet that one has. However, every bitcoin wallet stores your private key/s which are used for signing the transactions.
Types of wallets that we learned about and their features in short:
- A full node: has a wallet which stores private keys and also has the always up-to-date copy of entire blockchain
- SPV (Simplified Payment Verification): stores the private keys but pings full nodes to retrieve the information about the blockchain that it needs
- Paper wallet: stores the private key; usually one time usage; offline - most secure in that sense; not recommended to burn before use; place in the bin dedicated to paper waste
- Hardware wallet: stores private keys; transactions are confirmed on the device itself and never on userās computer, thus it keeps the private keys offline, stored and used on the device itself. doesnāt have the full copy of the blockchain but queries it when needed. The most flexible and secure option IMO.
- Hosted wallets (like on Coinbse accounts, Binance, etc.): NUT YEER KEYZ NUT YEER BTC

A Bitcoin wallet is a storage place for oneās private key. That private key can then be used for signing transactions that are sent over the Bitcoin network of nodes to be validated by those nodes, whereby funds can be sent or received meaning that changes occur in the blockchain database.

A bitcoin wallet has the goal of signing transactions with a private key. Basically it stores the private key to perform any operation: e.g. Signing a transaction prior to encryption and broadcasting it to the network.

A Bitcoin wallet stores the private key to your bitcoin address. Using this private key it can sign transactions, thus spending your funds connected with your bitcoin address. Hardware wallets are the most secure as they store the private key safely offline on the device. Hosted wallets are not really wallets in the sense that you do not have the private keys yourself, and as the saying goes: not your keys, not your crypto!! There are apps that store your private keys on your computer, these are somewhere in the middle - you have your keys, yet they are vulnerable because they are accessible via the internet and so could possibly fall victim to malware or viruses.

It stores your private key which is needed to sign transactions which are sent to the bitcoin network/to connected nodes. This transactions are also created by the wallet. Also it reads the blockchain or queries a node which contains the blockchain to check if the transaction is accepted by the network and inserted in a block. A bitcoin wallet does not contain or store any bitcoin.

A bitcoin wallet is sending and receiving data. It stores your private key and connects it to your public key. When I make a transaction to someone, it is signed by my wallets private key, confirming my transaction and intention.
It connects to several Nodes, either directly or through SPVs, that searches the blockchain (or several Nodeās blockchain history if itās an SPV) for validation until it gets picked up by a Miner (who is also running a Node) who then confirms the transaction and adds it to the Blockchain.
There are no physical coins in a wallet, itās pure data of your total history of supply.

It creates your private key which is used to create your public key which is then used to create your bitcoin wallet address. The beauty of the private to public key relationship is its one way nature. The private key can easily generate the public key but it is borderline impossible to generate the private key from the public key.

The wallet āreceivesā bitcoin via itās bitcoin address which in turn allows it to send said bitcoin to other bitcoin addresses by signing the transaction with its private key. If you lose your private key you lose access to the bitcoin wallet.

It also ensures you have enough bitcoin to send the amount specified by adding up your UTXOs.

wallets store private keys. when you want to send BTC is will create and sign the transaction. it then broadcasts the transaction to the network. your wallet also monitors the network for transactions involving your public key.
i have a question though. since a wallet like trustwallet that is a mobile app and is connected to the internet, is it just as unsafe to store your funds on that as it is on an exchange?

If a wallet has good enough security it is considered safer than having funds on an exchange. You are the owner of private keys and a wallet should ensure they are encrypted on your phone.
However I would still use the mobile wallet as a hot wallet where you donāt store a majority of funds and own a hardware wallet where I store the majority of my coins.
