Demystifying Dynamic State Sharding: Shardeum’s Innovative Solution for Blockchain Scalability

In a rapidly evolving crypto landscape, where the number of global cryptocurrency owners is expected to triple in 2022, the challenge of achieving mass adoption is becoming increasingly evident. Current layer one (L1) blockchains are struggling to accommodate the growing user base without compromising decentralization and security. Traditional solutions, such as increasing block sizes or implementing layer two (L2) solutions, come with their own set of challenges.

The answer to this scalability conundrum lies in sharding, a technique that has garnered much attention in the blockchain community. But what exactly is Dynamic State Sharding, and how can it be the remedy to the scalability trilemma?

What is Sharding in Blockchain?

Sharding is a technique that involves partitioning a network’s computational and storage workload into smaller, manageable segments. Each shard, or partition, distributes the transactional load across different nodes, thus enhancing the efficiency and scalability of the network.

While sharding has been explored by various blockchains, it is crucial to understand the intricacies of Dynamic State Sharding, which sets Shardeum apart in the quest for scalable solutions.

What is Dynamic State Sharding?

Note, the following contents are an excerpt from a recently published blog that comprehensively explains how Shardeum will eventually solve blockchain trilemma. To begin with, the network won’t have a static group of nodes as fixed shards. Nodes on Shardeum are free to move around and accommodate more data as dynamic shards. Dynamic state sharding will work hand in hand with Shardeum’s auto-scaling feature allowing the network to automatically adjust the number and size of shards based on the current workload. This allows the system to optimize performance and maintain high levels of scalability as it grows and evolves.

Dynamic State Sharding, often referred to as dynamic sharding, is the most advanced form of sharding designed to adapt seamlessly to changes in the blockchain ecosystem. It offers flexibility and adaptability, dynamically sharding the State, Network, and Transactions, rather than using a predetermined method. This approach involves analyzing historical transaction data and trends within the global state of the network. As the name suggests, Dynamic State Sharding allows for effortless integration of upgrades without disrupting the ecosystem’s workflow.

One of its primary benefits is the efficient scalability of a blockchain network without disrupting operations or performance. Unlike static state sharding, which relies on predefined shard groups and sequential processing, Dynamic State Sharding permits the addition or removal of shards as needed. This flexibility ensures the network’s performance is optimized as it grows and evolves.

Dynamic State Sharding vs. Adaptive State Sharding

While Adaptive State Sharding is employed by networks like MultiversX, Dynamic State Sharding takes adaptability to another level. It proactively distributes the load efficiently, considering both the current state of the network and the global state of the blockchain. This proactive approach results in more balanced load distribution and faster transaction processing.

For example, Dynamic State Sharding may predict which shards are likely to become overloaded based on historical data, enabling it to proactively balance the load. This approach ensures that the network remains responsive and efficient, even during periods of high traffic.

Sharding by Zilliqa & Polkadot: A Comparative Perspective

While Shardeum is making waves with its Dynamic State Sharding, it’s essential to consider how it stands in relation to other prominent sharded blockchains, such as Polkadot and Zilliqa.

Polkadot’s Approach:

Polkadot, often heralded as a layer zero (L0) solution, embraces a unique approach to sharding. Within the Polkadot ecosystem, multiple heterogeneous chains known as parachains attach themselves to the Polkadot base layer. These parachains execute various transactions and claim to offer enhanced security and communication across the network’s parachains. Polkadot’s design introduces an intriguing solution to the challenge of scalability.

Zilliqa’s Sharding Method:

Zilliqa boasts the distinction of being the world’s first L1 blockchain to employ the sharding method, focusing on network-level sharding. While both Polkadot and Zilliqa have made significant strides in sharding technology, it’s Shardeum’s approach that introduces a fresh perspective to the conversation.

Shardeum’s Innovative Approach:

Sharded blockchains, like Zilliqa, typically group transactions into blocks and seek consensus at the block level. While this method theoretically offers efficiency, it also comes with inherent delays. Transactions must wait until consensus is reached across multiple shards for processing, consuming more time and resources in the process.

What sets Shardeum apart is its commitment to achieving consensus at the transaction level. In Shardeum’s paradigm, a transaction need not wait for consensus across multiple shards before processing. This fundamental difference allows Shardeum to introduce a set of unique features that, when combined, truly revolutionize scalability in a linear and horizontal manner.

By achieving consensus at the transaction level, Shardeum unlocks the following remarkable features:

1. Faster Transaction Finality: Shardeum significantly reduces the time required for transaction finality, enhancing the speed and responsiveness of the network.
2. Parallel Processing: Transactions on Shardeum can proceed simultaneously across multiple shards, resulting in faster transaction processing and reduced bottlenecks.
3. Atomic Processing: Transactions are processed atomically, ensuring that they are either fully executed or not executed at all. This guarantees the integrity and security of the blockchain.
4. Cross-Shard Composability: Shardeum’s architecture facilitates seamless interaction between different shards, enabling complex transactions and smart contracts to operate across the network.

5. Shardeum’s Path to Scalability: With its commitment to consensus at the transaction level and the introduction of these groundbreaking features, Shardeum is poised to redefine scalability in the blockchain landscape. Its ability to scale linearly and horizontally by accommodating a growing number of nodes sets a new standard for blockchain performance and efficiency. As Shardeum continues to evolve, it promises to play a pivotal role in bringing blockchain technology to the forefront of the digital world.

Atomic Processing & Cross Shard Composability

Crucial to sharded blockchains is the ability to support cross-shard communication, enabling complex transactions and smart contracts to function seamlessly in a sharded environment. Additionally, the concept of atomic processing ensures that transactions are executed entirely or not at all, enhancing security and reliability.

Shardeum’s Linear Scaling

Shardeum stands out as a pioneering blockchain that leverages Dynamic State Sharding, aiming to offer linear scalability. Every node added to the network immediately increases transaction throughput. By simply incorporating more nodes from the ‘standby’ validator pool during peak demand, Shardeum achieves remarkable transaction per second (TPS) growth.

This unique approach allows Shardeum to scale linearly, ensuring high throughput, decentralization, security, and consistent transaction fees. The goal is to mobilize millions of nodes to process over a million TPS, revolutionizing the Web3 ecosystem and eliminating data privacy middlemen.

Maintaining Low Gas Fees

Crucially, Shardeum’s consensus and processing occur at the transaction level, not the block level. Dynamic State Sharding efficiently distributes compute workload, storage, and bandwidth among nodes, leading to parallel processing of transactions and low overhead for validator nodes. This ensures that Shardeum can maintain low transaction fees for developers and end-users indefinitely.

Shardeum: A Unique Blockchain for the Future

Shardeum’s innovative approach to sharding, combined with its EVM compatibility, positions it as a robust platform capable of hosting a multitude of dApps and layer 2 solutions. It aims to surpass even Web2 networks in terms of throughput while retaining the essential characteristics of Web3 networks: decentralization and security. These developments promise exciting times ahead for the Web3 world.
