What is a Layer 1 Blockchain? A Layer 1 blockchain is a decentralized network that executes and validates transactions without a secondary network. This allows new tokens and decentralized applications to be created on the blockchain without relying on third-party infrastructure. The disadvantages of this type of blockchain include poor transaction throughput and low scalability.
Layer 1 blockchains validate and execute transactions without the need for another network
Blockchains are distributed ledgers which store and validate transactions. The main goal of a blockchain is to provide a public auditable record of all transactions, and layer 1 blockchains do this. These networks operate without the need for a second network to perform these tasks. While the blockchain trilemma is a complex issue, layer one solutions have shown promise.
While this approach is a great first step, it is not perfect. For one thing, it is expensive and requires lots of communication between machines. This slows down the transaction speed. Additionally, the PoW algorithm is environmentally damaging with each transaction. This limits the potential of Layer 1 blockchains, but the transition to proof-of-stake (PoS) is likely to make them more efficient.
Layer 1 blockchains are still not perfect, and many improvements are impossible or time-consuming. For example, Ethereum is currently developing a Proof of Stake process to reduce the scalability problem, but this is likely to take several more years. In addition, some use cases cannot be implemented on layer one, such as blockchain games. However, layer two solutions can solve these problems and improve the overall performance of the blockchains.
One of the most common layer-1 scaling solutions is sharding, a mechanism adapted from distributed databases. It partitions a blockchain network into separate datasets. Each shard is independently operated, and processes a subset of the network’s transactions. Instead of maintaining the entire blockchain, it processes each shard in parallel. This allows several transactions to be processed simultaneously without having to wait for another network to complete their processing.
They can support new tokens and decentralised applications
There are many Layer 1 Blockchains that can support new tokens and decentralised application development. Some of them have high growth rates and have proven to be popular with developers and investors. Others have fewer limitations than Ethereum and are less expensive. A list of these projects is available on DappRadar.
Layer 1 Blockchains are still relatively new, and some of the improvements they can support are still being developed. Implementing these improvements can be time-consuming and difficult. In addition, some use-cases are not suited to layer one due to scalability issues. For example, blockchain games cannot realistically use the Bitcoin network due to long transaction times. In such cases, layer 2 solutions can be built on top of the layer 1 network.
Blockchains are also becoming increasingly useful in financial services. For example, JPM Coin aims to facilitate cross-border payments between business clients. And several companies have already begun experimenting with blockchain technology, including Goldman Sachs and Citigroup. These companies are now working on a trial to implement a blockchain-based plastic recycling system. Using this technology, they can manage their data with the help of smart contracts, and create incentives for recycling.
Layer 1 Blockchains are the first layer of a decentralized ecosystem. Layer 2 Blockchains are third-party integrations of layer one networks that increase system throughput and number of nodes. While these solutions are relatively new, layer 2 technologies are gaining popularity and are proving to be the most effective solution for scaling PoW networks.
They suffer from low scalability
Despite recent improvements in blockchain technology, Layer 1 Blockchains have low scalability. This problem is one of the biggest obstacles to blockchain adoption. A new solution called Layer 2 is being developed to address this problem. This type of blockchain is built on top of an existing blockchain and allows transactions to be processed off the main chain, avoiding bottlenecks and congestion. Immutable X and Loopring are two examples of layer 2 solutions.
Both Ethereum and Bitcoin use a distributed consensus model to maintain the security of their networks. This requires multiple nodes to verify every transaction, reducing the risk of attacks. However, this approach also creates a high demand for throughput, causing users to experience a slow confirmation time and high transaction fees.
Another major problem with L2 is that it hinders the liquidity of the underlying chain. Liquidity is crucial for building a viable market for a currency like Ethereum. A stable market is important to maintain the value of the tokens and goods that users need to transact with. L2 also causes unnecessary onboarding issues, which make it difficult for users to track their funds.
While Ethereum has proven to be a successful smart contract layer 1 protocol, other smart contract layer 1 blockchains are also emerging. Some of them are focused on supply chain logistics, while others focus on international payments.
They have poor transaction throughput
Blockchains that run on Layer 1 have long had issues with scalability, latency, and transaction throughput. These problems can be mitigated by scaling. The following sections will discuss some of the current solutions and blockchain platforms. Read on to find out how to scale your Layer 1 blockchain.
The L1 provides security and consensus mechanisms. L2s are supposed to resolve these problems and add more scalability to the network. In this way, they can increase transaction throughput and security, which are important to dApps and apps. Ethereum is using L2 solutions and has been acquiring projects built on ZK-rollup.
Ethereum’s C-chain is a good example of a sharded blockchain. A specialized chain can increase the number of nodes on the network and make it more efficient. Avalanche is currently on its way to becoming a global asset exchange. However, it still faces some limitations, and investors should be aware of them.
Blockchains based on Layer 1 have poor transaction throughput, but that’s changing. Binance Smart Chain, for example, is an EVM compatible platform that offers low transaction fees and a discount on native exchange fees. The BNB Chain also offers interoperability with other blockchains and dapps. Avalanche is compatible with the Ethereum Virtual Machine (EVM), which allows developers to migrate their Ethereum dapps to it. Meanwhile, C-Chain is an Ethereum native blockchain that executes Ethereum-native dapps.
Despite these shortcomings, a layer-one blockchain is the most suitable choice for large-scale protocol upgrades. Its goal is to improve the architecture of the blockchain. However, it has limited interoperability within a network, and its users are limited to the protocol of the solution that they implement.
They use Proof-of-Stake (PoS) consensus
Layer 1 Blockchains use Proof-of-stake (PoS) as their primary consensus mechanism. This type of consensus has distinct characteristics and aims. For instance, Bitcoin is designed for fast, low-cost transactions. Ethereum, meanwhile, was the first mainstream blockchain to incorporate smart contracts. It also hosted the first wave of dApps and tokens.
PoS has many benefits. First, it reduces the amount of resources that are required to achieve consensus. Second, it allows for sharding, a scaling mechanism that allows more transactions to be processed in a given amount of time. Eventually, blockchains using this method will be much more efficient than their PoW counterparts.
In addition to the increased efficiency, PoS also eliminates the potential for collusion. In PoS blockchains, validators use their own cryptocurrency to stake on the network. Often, validators are randomly chosen to participate in the process. Once they have submitted a valid block, other validators attest it. Once this process is complete, the block is added to the blockchain. The validators are rewarded for successful block proposals and attestations.
PoS is one of the most popular consensus mechanisms. It replaces the traditional Proof-of-Work algorithm, which was first introduced with Bitcoin in 2011. PoW cannot meet the demand for increased throughput. It also requires a lot of energy.
