However, because of scalability challenges in blockchain, blockchain performance issues, especially slow blockchain transaction speed and high fees persists despite blockchain\u2019s potential to revolutionize industries. In scaling public blockchains, the most challenging problems are in the consensus mechanisms in public blockchains as well as the management complexity in the growing user base.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Thus, to handle the deployment, they are exploring the way towards Scaling Layer 1 versus Scaling Layer 2. Layer 1 solutions aim to solve certain aspects of the blockchain through sharding it or lowing blockchain gas fees. On the other hand however, Layer 2 blockchain solutions seek to alleviate blockchain network congestion on the basis of onchain vs offchain scaling, such as state channels in blockchain and rollup (Optimistic and ZK-rollup).<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Businesses can seek help of a trusted blockchain development company or mobile app development company to put forward the best blockchain scalability solutions. When dealing with a trustworthy blockchain app development company, it cuts down the costs involved in the development of blockchain apps and also provides superior performance. Symptoms of scalability issues can be solved by hiring blockchain developers or dedicated ones to achieve high throughput blockchain applications.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Understanding_Blockchain_Scalability\"><\/span><span style=\"font-weight: 400;\">Understanding Blockchain Scalability<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Blockchain scalability means how much transactions a network can process per second.

To deal with these problems, many developers and researchers have presented many innovative solutions to attaining blockchain scalability. In general, these solutions can be classified into Layer 1 and Layer 2 scaling methods, which have each one set of advantages and disadvantages.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Layer_1_Scaling_On-Chain_Scaling\"><\/span><span style=\"font-weight: 400;\">Layer 1 Scaling (On-Chain Scaling)<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Layer 1 scaling is a process of modification on the underlying protocol to enhance its capacity and make the transaction speeds faster. To improve Layer 1 solutions, the blockchain architecture itself must be changed through changing the consensus mechanism and the data storage.<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Blockchain Sharding \u2013 Sharding technology in Blockchain involves dividing the network into smaller parts called shards, which are able to manage the blockchain more easily. The total transactions are distributed between a set of shards, each of which applies a portion of that to overall total and operate in parallel, in order to achieve higher total throughput of the network overall. The sharding which is being implemented as a key part of the Ethereum 2.0 upgrade is meant to improve scalability.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Traditional blockchains that employ Proof of Work (PoW) are as secure as they are slow and resource intensive. The only way to increase the speed with which transactions are processed on the blockchain is to switch to an alternative consensus mechanism such as Proof of Stake (PoS) or Delegated Proof of Stake (DPoS).<\/span><\/li>\n<\/ul>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Increasing Block Size \u2013 Reducing the number of transactions per block increased the network\u2019s transaction throughput. Larger blocks however, need more storage and more computational power and that could reduce decentralization.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">High Throughput Blockchain can be developed specifically for high throughput increasing transaction capacity and speeding up the network. For that, we can use Solana\u2019s particular Proof of History (PoH) consensus mechanism to support high speed transactions.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Layer_2_Scaling_Off-Chain_Scaling\"><\/span><span style=\"font-weight: 400;\">Layer 2 Scaling (Off-Chain Scaling)<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Layer 2 scaling solutions are built on top of main blockchain network that help congest the network and leady faster transactions by offboarding transactions off the chain. With layer 2 solutions, the blockchain is able to process more transactions without overwhelming the main network, which is called layer 1.<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">State Channel In Blockchain \u2013 State channels are when two or more parties run multiple transactions without having to depend on Blockchain. The blockchain stores only the initial and final states, reducing the on chain transactions by the order of magnitude and improving the transaction speed. State channels at work are the Bitcoin Lightning Network and Ethereum\u2019s Raiden Network.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Rollups in Blockchain: Rollups are the bundling of many transactions out of chain which are then posted on main chain by a single transaction. It reduces congestion and maximizes the transaction throughput.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Rollups, optimistic \u2013 Believe that in the majority of cases, a transaction is valid and loses if a disputed transaction is challenged.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Zero-knowledge Rollups \u2013 Transaction verifications are performed using zero knowledge proofs allowing the validation of transactions quickly, without seeing what they are, improving security and scalability.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Independent blockchains \u2013 Blockchains function apart from the main chain for transactions. Fast and more scalable processing, without compromising the security of the main chain can be done with side chains. One such well known side chain is Polygon that boosts Ethereum\u2019s scalability.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Plasma Chains \u2013 Plasma is root framework that implements chains which process transactions independently and submitted to the main chain its final state only. It reduces the loading on the main chain, however, only increases the security.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Blockchain_Gas_Fees_Optimization\"><\/span><span style=\"font-weight: 400;\">Blockchain Gas Fees Optimization<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Major blockchain scalability problems are the high transaction costs. Methods of optimization of the blockchain gas fees are aimed at minimizing the computational and storage costs associated with the processing transactions. Improving contract efficiency of smart contracts, better selection of consensus algorithms, and utilizing layer 2 scaling solutions can be some reforms.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Hybrid_Scaling_Combining_Layer_1_and_Layer_2\"><\/span><span style=\"font-weight: 400;\">Hybrid Scaling (Combining Layer 1 and Layer 2)<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">The best blockchain scalability solutions are an integration of Layer 1 and Layer 2 solutions. For instance, combining sharding (Layer 1) with rollups (Layer 2) allows Ethereum 2.0 to have high throughput and low transaction costs. Typically, scalability and efficiency of a high performance blockchain architecture is improved at the protocol and network layers.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Cross-Chain_Interoperability\"><\/span><span style=\"font-weight: 400;\">Cross-Chain Interoperability<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Interoperability amongst the different blockchains can moderate the traffic on each network, enhancing the overall capacity of the transactions. Various blockchains can communicate and transfer data to each other through platforms such as Polkadot or Cosmos, thereby increasing overall scalability and network efficiency.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Challenges_in_Scaling_Public_Blockchains\"><\/span><span style=\"font-weight: 400;\">Challenges in Scaling Public Blockchains<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">As public blockchains are open and decentralized, they have special scaling challenge issues. Public blockchains are different from private blockchains in that they have to strike a balance between scalability, security and decentralization, whereas it is easier to optimize the transaction throughput in private blockchain because only the particular group has access. To resolve these problems, solutions like sharding, rollups, and refined consensus mechanism are employed in order to make the network accurate.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Role_of_Blockchain_Development_Companies\"><\/span><span style=\"font-weight: 400;\">Role of Blockchain Development Companies<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">If a company wants to implement blockchain solutions for scalable use, they must take help from blockchain development company or blockchain app development company. Given that application setup and overall stream processing logic are handled by bolt and using bolt\u2019s comprehensive configuration, experienced developers are able to design and implement customized scaling solutions for the particular requirements of the project. A solution is supposed to be secure, efficient, and capable of handling high volumes of transaction. To do so, hiring skilled blockchain developers is essential.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Blockchain_App_Development_Cost_and_Hiring_Strategy\"><\/span><span style=\"font-weight: 400;\">Blockchain App Development Cost and Hiring Strategy<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">As essentially everyone knows by now, that the cost of blockchain app development depends on factors such as complexity of the solution, underlying technology stack, and scalability demands. If you are a business to develop blockchain deployed at scale, you have to hire blockchain developers or developers with experience in various layers of the ladder and their solutions. However, as far as many companies are concerned, the initial development costs are less than the long term benefits of increased scalability and improved performance.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/technoyuga.com\/contact-us\"><img decoding=\"async\" class=\"aligncenter wp-image-3791 size-full\" src=\"https:\/\/technoyuga.com\/blog\/wp-content\/uploads\/2025\/03\/Blockchain-development-company-cta.png\" alt=\"Blockchain development company cta\" width=\"2560\" height=\"715\" srcset=\"https:\/\/technoyuga.com\/blog\/wp-content\/uploads\/2025\/03\/Blockchain-development-company-cta.png 1920w, https:\/\/technoyuga.com\/blog\/wp-content\/uploads\/2025\/03\/Blockchain-development-company-cta-300x84.png 300w, https:\/\/technoyuga.com\/blog\/wp-content\/uploads\/2025\/03\/Blockchain-development-company-cta-1024x286.png 1024w, https:\/\/technoyuga.com\/blog\/wp-content\/uploads\/2025\/03\/Blockchain-development-company-cta-768x214.png 768w, https:\/\/technoyuga.com\/blog\/wp-content\/uploads\/2025\/03\/Blockchain-development-company-cta-1536x429.png 1536w, https:\/\/technoyuga.com\/blog\/wp-content\/uploads\/2025\/03\/Blockchain-development-company-cta-595xh.png 595w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><\/a><\/p>\n<h2><\/h2>\n<p>&nbsp;<\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Case_Studies_and_Real-World_Examples\"><\/span><span style=\"font-weight: 400;\">Case Studies and Real-World Examples<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Public and private networks are battling with a common problem: the challenge of blockchain scalability.
