Linea is a crypto network (a blockchain) that is part of the larger Ethereum family.
But instead of being a new crypto, it is what is called a layer 2 (Layer 2) of Ethereum.
đ Imagine Ethereum as a very secure main highway,
but often congested and expensive to use (gas fees can be costly).
Linea is like a fast ramp next to that highway:
she does the calculations elsewhere,
then it sends a verified summary to Ethereum,
which makes everything cheaper and faster...
while remaining as secure as Ethereum.
âïž 2. How does it work in practice
When you make a transaction on Linea (e.g., send money, buy an NFT, lend cryptos):
1. It is processed on Linea, so it is fast and inexpensive.
2. Then, Linea sends a mathematical proof (called zero-knowledge proof) to Ethereum to confirm that everything is correct.
3. So you save time and pay less, without sacrificing security.
Itâs like making a payment through a mobile app that combines several operations and then sends a single receipt to the bank.
đĄ 3. What is it used for in real life?
