Is Ethereum ERC-20 or trc20?

I'm trying to understand the difference between Ethereum ERC-20 and TRC20, but I'm a bit confused. Could you please clarify for me? I've heard that ERC-20 is a standard for tokens on the Ethereum blockchain, but what about TRC20? Is it related to another blockchain platform? If so, which one? Also, I'm curious about the similarities and differences between these two token standards. Could you outline the key points for me? I'm eager to learn more about this fascinating area of cryptocurrency and finance.
