About some balance terminology

Question

Background

when reading the code about pallet balance and some low-level code.I notice some terminology about balance.

terminology

• Burn
• Slash
• Reserve
• Lock
• Withdraw
• deposit

What is the meaning and specific difference of the above terminology, I have some doubts about this

Answer 1

• Burn: To remove some balance or asset from issuance.
• Slash: The reduce an account's balance as punishment.
• Reserve: To set aside some account's balance so it cannot be used in any other way but is still associated with the owner.
• Lock: To set a lower-limit on the account balance so a transfer or other elective balance-reducing operation cannot reduce it below this amount. Unlike with reserving, multiple locks on the same account "overlap".
• Withdraw: To reduce the balance of an account. There is an expectation that this is a counterpart to some other operation(s) which will leave a deficit of tokens and thus that by doing both/all operations, the total issuance across the system will be correctly accounted.
• Deposit: To increase the balance of an account. There is an expectation that this is a counterpart to some previous operation(s) which left a surplus of tokens and thus that by doing both/all operations, the total issuance across the system will be correctly accounted.
