- Scalability is crucial for a network’s ability to manage growing data or transactions.
- To improve scalability methods such as sharding, off-chain transactions are investigated
Scalability refers to how well a network can manage growing amounts of data or transactions. As the network’s user base and volume of transactions grow, so does the demand for processing power and other network resources, making blockchain scalability a crucial factor for users and developers to take into account.
Slow transaction processing times, excessive fees, and a bad user experience happen when a network is unable to handle the transaction demand or needs. Blockchain developers are investigating alternatives including sharding, off-chain transactions, and alternative consensus techniques to address scalability issues.
How Is Blockchain made scalable?
When the nodes involved in the blockchain agree on a block by the established standards, a scalable blockchain will have a high TPS. Blockchain scalability may be impacted by several issues, including networking, cost and capacity, finality, throughput, and confirmation time. As a result, when a blockchain network has a high TPS, it can be said to be scalable.
In the cryptocurrency industry, blockchain scalability is seen as both a challenge and a holy grail. It is a crucial factor in determining a blockchain’s future. In actuality, an excellent scalable blockchain is capable of supporting ‘n’ blockchain use cases without suffering any performance degradation. Decreased performance, however, simply indicates that the blockchain is not scalable.
Methods investigated to improve scalability?
- Sharding
Sharding is a technique that divides the blockchain or database into more manageable, more compact pieces known as shards. A portion of the data from the entire network is stored in each shard. Through parallel processing, this method lessens the load on individual nodes that must process the full blockchain. It can greatly increase scalability and transaction throughput.
- Layer 2 remedies
A significant percentage of transaction processing from the main chain is intended to be offloaded by layer 2 solutions, which are protocols built on top of current blockchain networks. State channels (like the Lightning Network for Bitcoin) and sidechains are examples of Layer 2 solutions. These methods can significantly improve scalability by managing transactions off-chain and only committing the final result to the main chain.
- Enhanced consensus algorithms
A crucial part of blockchain systems, the consensus algorithm’s effectiveness is crucial for scalability. In place of the energy-intensive Proof-of-Work (PoW) employed in Bitcoin, protocols are investigating other consensus algorithms like Proof-of-Stake (PoS) and Delegated Proof-of-Stake (DPoS), which utilize less energy and enable faster transaction confirmations.
- Rollups that are optimistic
Rollups that are optimistic are Layer 2 scaling techniques that group together several transactions off-chain before submitting a single summary transaction to the main chain. Cryptographic proofs confirming the accuracy of the off-chain transactions are included in this report. Optimistic roll-ups can increase throughput and lower costs by reducing on-chain interactions.
- Plasma
Plasma is a Layer 2 solution that also tries to improve scalability by building hierarchical networks of connected blockchains, with the main chain serving as the root. It enables a greater volume of transactions to be performed off-chain while still preserving the main chain’s security.
- Data compression and pruning
Data pruning involves deleting extra data from the blockchain to make it smaller, allowing for more effective storage and quicker synchronization for new nodes. The amount of data that needs to be transmitted across the network can be decreased by using data compression techniques, further enhancing scalability.
- State channels
State channels enable several off-chain transactions between two or more parties, establishing the final state on the main chain only when required. State channels can dramatically increase scalability for particular use cases, such as gaming or micropayments, by avoiding on-chain transactions for every operation.
- Parallel processing
Some protocols investigate ways to make transactions process in parallel. The workload can be distributed among several nodes or processors, allowing the system to handle transactions more rapidly and effectively.
