Various Sharding Methods in Blockchain: An Overview
Ready to dive into the world of sharding blockchain types? Let's break it down and learn about different methods to scale blockchain technology!
What is blockchain sharding?
As you probably know, blockchain involves tons of data and transactions. Sharding comes into play by breaking down large databases into smaller, more manageable chunks, or shards. Think of it like multiprocessing on your computer - instead of your central processing unit dealing with everything, you break down tasks to be handled by multiple threads. This concept allows for parallel processing, improving overall efficiency and transaction throughput.
Horizontal vs Vertical Sharding
You've likely come across terms like horizontal and vertical scaling in relation to tech infrastructure. Sharding uses the same concepts:
Horizontal Sharding
In horizontal sharding, larger data tables are divided into smaller, smaller tables. These tables usually share the same schema but contain unique entries. More machines are then added to process the load, effectively increasing processing speed. It's like assigning multiple workers to complete different tasks at the same time.
Vertical Sharding
Unlike horizontal sharding, vertical sharding involves adding new tables with different schemas to the mix. This method is used when queries return only a subset of the data columns.
Types of Sharded Blockchain
Now that you've grasped the basics of sharding let's dive deeper into various types of sharded blockchains:
Network Sharding
Network sharding enables separate teams of nodes to process groups of transactions. These nodes have a synchronization mechanism to align transactions across the network, which improves the chain's overall throughput. However, it still faces the same scalability issues as vertical scaling, with increasing costs over time and the potential for sybil attacks.
Transaction Sharding
Transaction sharding doesn't modify the ledger structure; instead, it distributes the addresses structure among shards to increase transaction speeds in the same shard. You might think of it as a more streamlined approach compared to network sharding, focusing on the same overall goal: achieving increased throughput or TPS. This method also offers atomic and cross-shard composability, which is beneficial for developers building smart contracts and applications.
State Sharding
State sharding takes the division to another level, splitting the complete state into separate shards. This approach makes transaction verification and processing faster, more accurate, and secure. However, it comes with challenges: each shard must stay in constant contact and be rapidly responsive since each shard holds only a portion of the state ledger. This can lead to increased latency as new nodes join the network.
Examples of Sharding
Blockchain sharding types have made a significant impact on how we process high volumes of transactions, reducing latency and improving overall efficiency. Examples of sharding in action include:
- NEAR Sharding Near Sharding is a real-time, user-friendly sharding experience, designed to handle complex transactions without overloading the system. It supports proof of validity and allows low-end devices to act as nodes.
- Ethereum Beacon Chain Ethereum's Beacon Chain acts as the backbone for the new Casper proof of stake system. It manages tasks like crosslinks, adding storage, validator maintenance, and execution of ethereum blocks.
- Polkadot Parachain Polkadot Parachain is a unique approach to distributed database sharding, associating with the security offered by a relay chain. It facilitates efficient transaction operations and data storage for the blockchain.
- Sharding by Zilliqa Zilliqa uses network-level dynamic sharding to scale its blockchain. Transactions on Zilliqa are divided into microblocks and processed in parallel by different shards, enhancing scalability and overall network performance.
