The Lightning Community is Bitcoin’s Layer-2 scaling answer. Polkadot is a Layer-2 platform that solves Ethereum’s scalability points. In case you have paid even a little bit little bit of consideration to cryptocurrencies or blockchain, you have to have come throughout phrases like Layer-1 and Layer-2 protocols. Questioning what these layers are and why they exist within the first place? Let’s discover out.
Why Do We Want Layers?
Blockchain is a novel mixture of a number of already current applied sciences – cryptography, sport principle, and many others. – with a lot of potential functions. Cryptocurrencies are simply one among them. It brings effectivity, transparency, and safety to take away intermediaries, deliver down the prices, and convey effectivity.
The distributed ledger expertise (DLT) shops data verified by cryptography amongst a gaggle of customers, agreed by means of a predefined community protocol with out a government oversight. It’s the wedding of those applied sciences that deliver belief between individuals or events who in any other case don’t have any motive to belief each other. They allow blockchain networks to securely switch worth and knowledge straight between customers.
Blockchains should be extremely safe within the absence of a centralized authority. And so they should be extremely scalable to accommodate a quickly rising variety of customers, transactions, and different knowledge. It’s the necessity for scalability whereas sustaining top-notch safety that gave rise to layers.
The 4 Layers
Teachers haven’t finalized the conceptual fashions of blockchain networks but. However, in essence, a blockchain community contains 4 layers that every add totally different elements to the ecosystem.
Layer zero is made up of issues that kind the groundwork making blockchain a actuality. It’s the infrastructure required to assist Bitcoin, Ethereum, and different blockchain networks. Layer zero elements are the Web, {hardware}, and connections that allow clean operations of Layer-1.
That is the bottom layer that depends on its immutability for safety. When individuals say the Ethereum community, they’re referring to Layer-1. This layer is liable for consensus mechanisms, computing language, block time, dispute decision, and the foundations and parameters that guarantee the bottom degree performance of a blockchain community. It’s sometimes called the implementation layer.
One of many major points skilled in L1 is scalability wanted to accommodate a quickly rising quantity of information. As customers, transactions and different knowledge on Layer-1 improve, the pace of transactions reduces. Transactions turn into extra pricey to execute rapidly because the visitors rises.
To resolve these issues of scalability and price of transaction, whereas nonetheless sustaining the advantages of Layer-1 (safety, battle decision and many others), there’s a want for a second layer.
L2 options are the overlaying networks that lie on high of the bottom layer. Protocols use Layer-2 to spice up scalability by taking a number of the interactions away from the bottom layer. So, sensible contracts on the principle blockchain protocol solely deal with deposits and withdrawals, and confirm that the off-chain actions have obeyed the foundations.
There are a number of various Layer-2 applied sciences akin to sidechains, ZK rollups, Optimistic rollups, Plasma framework, and extra to beat the principle blockchain’s scalability limitations and operational difficulties.
To offer a sensible instance, Celer Community is a coherent Layer-2 scaling platform constructed on the Ethereum community. It’s driving mass adoption of blockchain expertise by enabling a frictionless expertise. Celer permits customers to make use of current DeFi protocols with as much as 100x decrease prices with no concern of safety points because it doesn’t trigger liquidity fragmentation or break composability.
Celer Community developed the first-ever Layer-2 State Channel Community that helps pace up transactions and cut back gasoline charges by greater than 100X on Ethereum, DFINITY and many others. It additionally helps different blockchains like Polkadot.
Layer-3 is sometimes called the applying layer. The L3 initiatives masks the technical particulars of the communication channel and function a person interface. It’s the L3 functions that create real-world use circumstances for blockchains.

🥳Less complicated UX: two-click -> one-click
💵Decrease price: lowest gasoline + environment friendly pricing
🌊 Simpler LP/X: no must run a node, single-click liquidity administration, farming built-in

Persevering with our instance of the Celer community, decentralized apps constructed on high of Celer are Layer-3. The Celer platform supplies a scaling answer enabling builders to construct quick and safe dApps with out being affected by the restrictions of Layer-1 blockchains.
Conclusion
There you’ve it: An outline of assorted layers of a decentralized community with out an excessive amount of technical jargon. L1 is the bottom infrastructure layer the decentralized programs are constructed upon. L2 resolves the scalability points by taking a number of the exercise off-chain to facilitate quick and low-cost transactions. A lot of the Layer-3 initiatives are decentralized functions that we work together with.
