Cryptocurrencies are constructed on blockchain networks. Very like a home is constructed beginning with a stable basis, a crypto community begins with its layer-1 blockchain. That is the bedrock of the complete system, dealing with processes like safety, transaction processing, and rather more.
This text will clarify precisely what we imply by layer-1 by way of cryptocurrency and blockchain know-how, from the definition of L1 blockchain to real-world use instances and examples.
What’s blockchain?
A blockchain community is a community of computer systems known as nodes which work collectively to course of data. This data is processed one block at a time, and every block is added to a everlasting ledger that can not be edited until a majority of nodes comply with make a change.
As such, blockchain networks with many nodes can turn out to be very safe and troublesome to censor or assault. This safety and the immutable, unchangeable nature of the community data types the premise for cryptocurrency networks like Bitcoin.
What’s layer-1 blockchain?
A layer-1 blockchain in crypto is a community the place transactions are executed and confirmed immediately on the blockchain.
Whereas layer-2 blockchains exist to reinforce and take stress off of layer-1 blockchains, a layer-1 blockchain community is the primary community required for a cryptocurrency to operate.
Fr instance, Bitcoin and Ethereum are layer-1 blockchains and don’t want every other blockchain community so as to perform their operations, reminiscent of confirming transactions and minting or creating new models of foreign money.
Decentralization in L1 blockchains
In cryptocurrency, layer-1 blockchains are sometimes designed to be decentralized, that means nobody authority is controlling the nodes that course of the transactions and run the community.
Entities known as miners course of transactions in change for crypto rewards, and whereas smaller L1 chains are sometimes centralized, networks like Bitcoin and Ethereum are managed by competing mining swimming pools that be certain that no central determine is making all the choices.
This relative decentralization is a significant factor within the recognition of layer-1 blockchains, and of cryptocurrency basically.
Their independence permits them to create and improvise their native safety protocols and governance hierarchies, which in flip make them extra dependable than different forms of blockchain layers like Layer-2, Layer-3, and so forth. However what key options make layer-1 blockchains so dependable and strong? Let’s discover out beneath.
Key traits of layer-1 blockchain
Layer-1 blockchains supply a number of options all of which serve a singular goal in the long run, which is to boost the performance and autonomy of the complete blockchain ecosystem. Listed here are among the most necessary options:
1. Freedom
Independence is what makes layer-1 a simple promote for an upcoming cryptocurrency venture to construct its platform on layer-1 solely. By merely creating their governance and safety protocols, layer-1 blockchains be certain that their core features don’t depend on different blockchain layers, which immediately ensures a excessive degree of safety and decentralization.
2. Native cryptocurrency
Whether or not it’s staking, governance, or transaction charges, customers of layer-1 protocols should not required to purchase every other token to do these duties, quite solely the native cryptocurrency is used. This complete course of ensures transparency and belief, which provides to the expansion of the layer-1 blockchain community.
3. Consensus mechanisms
With a custom-made consensus algorithm, each layer-1 blockchain ensures community integrity and validates transactions with the very best quantity of safety protocols. Two main examples of such mechanisms embody Bitcoin which makes use of Proof-of-Work (PoW) and Ethereum which employs Proof of Stake (PoS). With its military of nodes following the consensus algorithm, the complete transaction course of turns into clear and safe.
4. Neighborhood-driven governance
Stakeholders play a key half in driving the ecosystem progress in layer-1 blockchains. This implies collaborating in voting processes that decide key selections that influence the way forward for the venture immediately. General this course of harmonizes a way of possession and promotes decentralization which performs a key function in encouraging new cryptocurrency tasks to construct on this house.
Different options embody scalability, sensible contract performance, and potential for ongoing improvement.
Listing of layer-1 blockchains
There are at the very least 130 layer-1 blockchains that provide safety, and autonomy, together with different key options talked about above. Right here, we’ll talk about the highest three layer-1 blockchains.
1. Bitcoin (BTC)
Launched in 2009 by an nameless founder often known as Satoshi Nakamoto, Bitcoin (BTC) is the daddy of cryptocurrencies and operates on the Proof-Of-Work (PoW) mechanism. As a layer-1 protocol, Bitcoin gives autonomy by providing strong safety features, enabling peer-to-peer transactions with out the necessity for a third celebration, all of which make it essentially the most trustable blockchain community and foreign money within the web3 world.
2. Ethereum (ETH)
Ethereum was the primary blockchain that launched the world of sensible contracts within the blockchain house. It opened new gateways of improvement within the blockchain world, because it turned simpler for web3 builders to construct decentralized functions (dApps) on the Ethereum blockchain. Ethereum additionally launched the Proof-of-Stake (PoS) mannequin which additional enhanced scalability whereas on the similar time lowering power consumption by a large margin.
3. Binance Good Chain (BSC)
Binance Good Chain serves two key options, one is to keep up low transaction prices and the opposite is to be at excessive efficiency always. This layer-1 blockchain has positioned itself on the planet of DeFi as nicely resulting from its user-friendly working system and quick transaction speeds, which makes it preferrred for the typical person in addition to new improvement tasks that need to construct on this layer-1 blockchain.
The way forward for layer-1 blockchains
There’s little doubt that layer-1 blockchains play a crucial function on the planet of decentralized applied sciences. From working decentralized apps, and executing transactions on stand-alone blockchain infrastructure, to sensible contracts, layer-1 blockchains act as a foundational platform within the blockchain world. Nevertheless, we will’t deny the truth that these networks nonetheless face challenges, particularly when transaction volumes and/or person adoption will increase with time.
To beat these challenges many of those layer-1 blockchains have began experimenting and doing analysis on bettering their architectural designs and consensus algorithms.
For instance, some blockchains have added mechanisms of Proof-of-Stake (POS) and sharding, to decrease transaction charges, and cut back latency, nevertheless, regardless of these crucial improvements layer-1 blockchains reminiscent of Bitcoin and Ethereum are nonetheless shifting in the direction of layer-2 blockchains which provide a wider vary of options to the challenges poised within the blockchain world.
Sooner or later, we will count on extra evolution from layer-1 protocols as they adapt to new ecosystems, turn out to be extra interoperable, and turn out to be a mixture of intrinsic enhancements, because of layer-2 and layer-3 blockchain applied sciences.
