Dapp is an abbreviation for decentalized applications. Ethereum (ETH) was one of the first (if not the first) blockchains to support smart contracts which are small applications that can be deployed on the blockchain and executed from another wallet address (or contract address). The applications themselves are called dapps and are stored inside of the blockchain at unique contract addresses. Wallet addresses and other contracts can send data to the contract address by calling the public functions of the dapp through another application such as a wallet or web3 browser. These applications need to have access to decrypt the private key address of your wallet address because in order to send messages to contracts which change the state of the blockchain come at a cost of Gas. Gas is measured in a unit called gWEI and represents one, one billionith of a full unit of ETH (or HPB). Learn more about smart contracts Here. The bottomline is that the code that these dapps contain contain cannot be changed once deployed which means that their behavior is 100% predictable and their rules cannot be broken or changed. However, if not carefully designed, they can be exploited. (Contracts can be designed to call other contracts to technically allow for changes but this beyond the scope of the overview).

Q.) I am no longer able to make transactions from metamask, I have tried resetting metamask,
uninstalling and reinstalling it but keep getting an error Internal JSON-RPC error -32603. How can I fix this?
A.)Load your account inside of the HPB wallet and make a small send transaction to another address.
This will increment the nonce value and correct the issue.
