Network (blockchain)
The environment where a cryptocurrency is issued and transferred (TRC20, ERC20, BEP20, etc.). The network affects fees, speed and address compatibility.
In more detail
One coin can travel on different networks (TRC20, ERC20, BEP20, TON), and the network choice affects the fee, speed and, crucially, address compatibility. Sending to the wrong network is the most common cause of irreversible loss for beginners. Before transferring, match the network on the sender and receiver side exactly.
