It’s day 12 of #web3glossary

You’ve heard L1 and L2 quite commonly in the web3 space, but not sure what does it refer to? Let’s dig in👀👇

L1: Layer 1
L2: Layer 2

(L1) is the basis of the blockchain architecture - base layer or mainnet. @ethereum , @FantomFDN & @Bitcoin blockchain are all L1 blockchains.
Layer-2 is a network that is built on top of the underlying L1 blockchain.

While thousands of DApps are running on main chains like Ethereum, its blockchain often struggles with congestion issues, leading to high gas fees and slow speeds🤯
That where L2 and sidechains come in
👇👇

L2 protocols are used to improve scalability, privacy, and add cross-chain communication in the existing networks. And also to provide for better TPS speeds and lower transaction fees.

While Sidechains are a separate blockchain network that runs in parallel to the main chain.

Both L2 & sidechain help in scaling L1 networks
❗️Unlike sidechains, which rely on their own consensus mechanisms, layer 2 solutions inherit the security of their underlying mainchain❗️

@0xPolygon provides both L2 &sidechains solutions through Polygon Proof of Stake & zk-Rollups

Now that we have optimized the network, let’s take a look at nodes. Nodes are present in a network to ensure that the data which is held on the node is valid, secure & accessible to the authorized parties.

Today's star is 👉 "Light node"

Its a computer that connects to a full node to further validate the information that is stored on the blockchain. Light nodes "do not" maintain the entire blockchain & address state and are hence smaller in size💯

They store only header chain information and receive additional information upon request. They’re able to verify the validity of data but do not fully participate in block validation.🤩

Light nodes comes with benefits👇👇

It enable users to participate in the network without powerful hardware or high bandwidth required to run full nodes.
Who knows, one day light nodes might run on mobile phones or embedded devices.🚀🚀

That’s a wrap for Day 12!
I’ll be sharing information on the new vocabulary of the web for next 30 days.
It’s like a free crash course on the terms and methodolgies in Web3.
