Blockchains have change into extremely common applied sciences for funding and funds. This is because of their decentralized nature, safe networks and ease of funds. The most typical type of blockchain is named layer 1 blockchain. Nonetheless, L1 blockchains undergo from scalability points, which result in community congestion and large prices. One doable answer to it is a layer zero community.
Introduction to Layer 0
Common layer 1 blockchains are self-sufficient techniques, which might deal with community safety, validation and full transactions with none exterior help. However this additionally means there are a number of totally different duties the identical community should carry out, slowing down the efficiency significantly.
Layer 0 as a substitute consists of the underlying community on high of which a blockchain is constructed. This contains options like protocols, community construction, {hardware} and validator nodes. Layer 0 blockchains permit a number of layer 1 blockchains to be constructed on high of them, enabling them to make use of the identical underlying techniques and protocols.
How Does Layer 0 Blockchain Work?
A layer 0 protocol requires three fundamental parts to operate seamlessly.
Mainnet
The primary chain or mainnet of layer 0 is what consolidates and shops knowledge from the assorted layer 1 blockchains constructed on high of it. This helps preserve a community state and ensures knowledge integrity is maintained throughout the protocol.
Sidechains
This element contains the various layer 1 blockchains constructed on high of layer 0. They will have their very own nodes and consensus mechanism however nonetheless profit from cross-chain compatibility and safety supplied by L0.
Cross-Chain Operations
An enormous benefit of constructing on layer 0 is that your dApp will preserve compatibility with each different blockchain in the identical community. That is accomplished by way of the inter-blockchain switch protocol, which ensures all belongings and data will be shared between the mainnet and different sidechains.

Layer 0 Scalability
The issue of scalability stems from the “Blockchain Trilemma”, a time period coined by Ethereum founder Vitalik Buterin. This idea says that blockchains expertise a tradeoff between decentralization, safety and scalability. Normally, blockchains can solely carry out 2 of the three capabilities satisfactorily.
L0 protocols can’t course of transactions by themselves. That may be a function carried out by the principle chain and varied sidechains constructed on the blockchain. Scalability on an L0 thus means including extra unbiased blockchains and purposes to the community. Every one operates independently of the others, which ensures one blockchain is just not slowed down by exercise on one other.
What are some Layer 0 Blockchain Tasks?
The three hottest Layer 0s are Cosmos, Polkadot and Avalanche.
Cosmos
This challenge is making an attempt to construct an “Web of Blockchains” as an alternative choice to older techniques like Bitcoin and Ethereum. The community is cut up into the Cosmos Hub – its predominant chain – and hundreds of unbiased sidechains that may launch their very own purposes.
Cosmos’ operations are enabled by way of the Tendermind consensus mechanism. It additionally makes use of a novel inter-blockchain communication protocol to allow knowledge sharing between its sidechains. Lastly, the Cosmos software program improvement package makes it straightforward for builders to launch their very own sovereign blockchain to construct an software.

Polkadot
Polkadot is a layer 0 protocol on which a number of specialised blockchains often called “parachains” are constructed. Below this method, Polkadot can present scalability to all tasks by way of a standard validator pool. Thus, the price of transactions is unfold throughout a number of parachains.
You’ll be able to construct a singular blockchain on the protocol in minutes with the Substrate framework. The community is extremely environment friendly, utilizing the power equal of simply 7 households per yr. Its operations and governance are additionally decentralised, the place all of its tokens are given a voice.

Avalanche
Avalanche is a decentralised good contract platform for dApp creation. It permits you to simply construct Ethereum-compatible dApps that may course of hundreds of transactions every second.
The primary promoting level of this platform is that it takes lower than 2 seconds to finalize a transaction. This quantity will be as excessive as 60 minutes and 6 minutes with Bitcoin and Ethereum respectively. Customers may also stake their AVAX tokens or run nodes with the {hardware} they already personal.
What’s The Way forward for Layer 0 Blockchain?
Layer 0 protocols are unbelievable options to the blockchain trilemma that cater to consumer wants higher than older blockchain tasks. L0s additionally supply unbelievable flexibility to builders by permitting them to create unbiased blockchains for decentralized purposes.
This answer might be able to permit for infinite scalability of a community to match demand at any time when required. It additionally attracts extra customers to blockchains by resolving long-standing problems with excessive prices and congestion.
