What is Shardeum (SHM)?

Shardeum is an EVM-based Layer 1 blockchain that scales horizontally, delivering high speed and low gas fees without sacrificing security or decentralization. As a sharded, Ethereum-compatible, smart contract platform, Shardeum is powered by the Shardus protocol, which employs dynamic state sharding, cross-shard atomic composability, auto-scaling, linear scaling, and other novel technological innovations designed to solve the blockchain trilemma.

The native coin on Shardeum is “Shard” with “SHM” as its ticker symbol. SHM serves multiple functions within the Shardeum ecosystem, including transaction fees payment, validator staking, governance, and rewards distribution. With its unique architecture, Shardeum aims to enable applications like AI and trading platforms to scale affordably on its network, merging blockchain’s benefits with the ability for users to maintain control over their resources, free from central points of failure.

What is the Relationship Between Shardeum and SHM Token?

Shardeum refers to the entire blockchain platform and infrastructure, while SHM is the native cryptocurrency of this network. This relationship can be compared to how Ethereum is a blockchain platform and ETH is its native token.

SHM has multiple functions within the Shardeum ecosystem:

It serves as the primary medium of exchange on the Shardeum network
It enables users to pay for transaction and gas fees
It allows holders to participate in network governance
It can be staked by validators to secure the network and earn rewards

In the cryptocurrency space, the terms coin and token are often used interchangeably, especially on Ethereum-compatible platforms. Since SHM is the native currency of Shardeum, it is technically a coin. Nonetheless, SHM can very well be referred to as a ‘token’, as a tokenized version will be used in the context of smart contracts and certain utilities, aligning with common industry terminology.

What Does Shardeum Aim For? Solving the Blockchain Trilemma

The blockchain industry faces a unique challenge: it must efficiently scale, become user-friendly, and reduce costs as demand grows, all while maintaining high levels of decentralization—a requirement traditional systems don’t need to fulfill. This three-dimensional problem is known as the “blockchain trilemma,” where conventional blockchains can only optimize for two out of three key properties: scalability, security, and decentralization.

Early Layer 1 blockchains like Bitcoin self-limited their scalability to prioritize security and decentralization. This lack of scalability has led to continued reliance on traditional centralized institutions, which historically have been prone to exclusivity, misuse of power, and lack of transparency.

The specific problems Shardeum aims to solve include:

Limited Scalability: Existing Layer 1 blockchains have architectural limitations and rely on vertical scaling, which curtails scalability once maximum TPS is reached, resulting in network congestion and high gas fees during peak demand.
High Transaction Fees: During times of network congestion, transaction fees can increase exponentially, making many use cases for blockchain technology economically unfeasible.
Poor User Experience: High fees and slow transaction confirmation times create a poor user experience, hindering mainstream adoption.
Compromised Decentralization: Many scaling solutions sacrifice decentralization to achieve higher throughput, going against the core principles of blockchain technology.
Limited Application Possibilities: Current blockchain limitations prevent the development of complex, high-throughput applications like AI and trading platforms.

Shardeum Founders and Roadmap: From Concept to Mainnet Launch

Shardeum’s development journey began with its foundational technology, Shardus, which has been under development since 2016. Omar Syed, a systems architect with experience building scalable systems for organizations like NASA and Yahoo, started working on a distributed ledger design that would process transactions independently without grouping them into blocks, making it easier to shard the ledger.

Here’s the timeline of Shardeum’s development:

Q2 2016: Omar Syed began working on the design of a distributed ledger (later named Shardus).
Q3 2021: The Shardus team demonstrated linear scaling and auto-scaling by growing a sharded token transfer network to 1000 nodes and achieving 5000 TPS.
Q4 2021: Nischal Shetty, Founder and CEO of WazirX, invited Syed to Dubai to discuss creating a smart contract platform based on Shardus technology, giving birth to the idea of Shardeum.
Q1 2022: The Shardeum Liberty Alphanet was launched on February 2nd, 2022, allowing the community to deploy EVM-compatible smart contracts.
Q1 2023: The Shardeum Sphinx Betanet was launched on February 2nd, 2023, enabling community members to run validator nodes, with over 25,000 nodes eventually joining the network.
Q1 2024: Continued Betanet operation and completion of patent filing for technological innovations.
Q2 2024: Open-sourcing of code and initiation of multiple open-source projects.
Q2 2024: Launch of Atomium Incentivized Testnet in June 2024, which saw over 31,000 validators, 638,000 wallets, and 23 million transactions within the first six months.

How Does Shardeum Solve Blockchain’s Scalability Issue in Terms of TPS?

1. Dynamic State Sharding

Shardeum employs dynamic state sharding to split the network at the protocol layer into multiple shards, each capable of independently processing transactions. Unlike traditional blockchains where transactions are processed sequentially in a single chain, Shardeum’s approach enables parallel transaction execution, significantly increasing the network’s throughput while maintaining atomic composability.

2. Auto-scaling

As an industry first, Shardeum features auto-scaling capabilities that adjust its capacity based on real-time network demands. As transaction volumes increase, Shardeum dynamically scales up by adding more shards to handle the load, ensuring that performance remains high without compromising on speed or cost. This is achieved by measuring network load every cycle (60 seconds) and autonomously adjusting the required number of validator nodes.

3. Proof of Quorum (PoQ) Consensus Mechanism

Shardeum implements a unique Proof of Quorum consensus mechanism where validator nodes within multiple shards verify and process transactions. If a transaction receives approval from more than 50% of the nodes in a shard, it is processed instantly, resulting in extremely low latency and finality times. This system is reinforced by Proof of Stake as a sybil deterrence mechanism, requiring nodes to stake SHM as collateral.

4. Low Entry Barrier for Validator Nodes

Shardeum lowers the barrier to running validator nodes by requiring minimal hardware capacity, making it more accessible for community participation. The network’s intuitive GUI dashboard allows users to manage their nodes with just a few clicks, even without technical skills, enhancing decentralization.

5. Linear Scaling

Through its combination of blockless transaction processing and dynamic state sharding, Shardeum achieves true linear scaling. For example, if 100 nodes provide 50 transactions per second (TPS), then 200 nodes will provide 100 TPS. This approach allows the network to scale horizontally by adding more nodes rather than vertically by increasing the power of existing nodes.

6. Low Transaction Fees Forever

One of Shardeum’s central design goals is to ensure sustainably low transaction fees. Since Shardeum auto-scales linearly, it maintains low network maintenance costs regardless of demand, resulting in consistently low fees for end users. This opens the door for innovative use cases previously impractical on other platforms due to prohibitive costs.

7. Atomic and Cross-Shard Composability

Unlike many sharded networks that break atomic composability, Shardeum maintains the ability to invoke multiple smart contracts and chain them together within one transaction, even across different shards. This results in a better user experience and lower transaction costs, as users can execute complex operations in a single transaction.

8. EVM Compatibility

Shardeum is EVM-based, making it compatible with Ethereum’s ecosystem of tools, wallets, and smart contracts. This compatibility allows developers to easily port their Ethereum applications to Shardeum without having to learn new programming languages or frameworks, facilitating rapid adoption.

Shardeum Tokenomics: SHM Supply, Distribution and Utility

Initial Supply and Distribution

Shardeum transitioned to a dynamically responsive supply model at the start of 2025, with an initial supply of 249 million SHM distributed as follows:

Sale: 91,440,000 SHM (36.72%) – 3-month cliff then 2-year daily linear vesting
Team: 76,200,000 SHM (30.6%) – 3-month cliff then 2-year daily linear vesting
Foundation: 55,880,000 SHM (22.44%) – unlocked at Token Generation Event (TGE)
Ecosystem & Airdrops: 25,480,000 SHM (10.23%) – unlocked at TGE

Similar to Ethereum, validator rewards will be dynamically generated based on network demand rather than pre-minted, creating a more sustainable and adaptive token issuance model. Since 100% of all transaction fees are burned, SHM is expected to be deflationary over time.

Token Utility

SHM serves several important functions within the Shardeum ecosystem:

Staking: Validators stake SHM to participate in the network, and this staked amount can be slashed if the node misbehaves, ensuring network security.
Transaction Fees: SHM is used to pay for transaction and gas fees on the Shardeum network, with all fees being burned to create a deflationary mechanism.
Governance: SHM holders can participate in network governance, voting on proposals and changes to network parameters.
Rewards: SHM is distributed as rewards for network participation, including validator rewards and ecosystem incentives.

Dynamic Supply Model

Shardeum’s tokenomics follow a dynamic supply model where issuance adjusts based on network demand and economic conditions. This ensures that the network can maintain the right balance of incentives for validators while preventing excessive inflation. Depending on network conditions, the supply can be:

Inflationary: When required to incentivize network growth and participation.
Disinflationary: When issuance remains positive but at a declining rate over time.
Deflationary: When demand results in burning mechanisms reducing the circulating supply.

This adaptive approach allows Shardeum to achieve supply equilibrium where the amount of SHM burned through transaction fees equals the amount issued to validators, creating a sustainable economic model for the long term.
