All over the world, conversations regarding the multifaceted prospects and use cases of blockchain technology in business are rife. Blockchain owes much of its success to people’s growing awareness of the benefits of decentralization. And it’s this desire to break free from centralization that provided the premise for a global wave of innovation in permissionless blockchain technology. However, most of the existing public blockchain iterations suffer from severe limitations in terms of scalability, which hinders their mainstream adoption and delays widespread public use. To address this and other pressing concerns associated with blockchain technology, Lucian Todea, Beniamin, and Lucian Mincu founded Elrond in 2017.

Elrond, by design, surpasses some of blockchain’s major limitations and achieves a higher throughput than even centralized digital payment companies like Visa do. In addition, Elrond dramatically reduces storage and bootstrapping costs to ensure long-term sustainability.

This insight talks about the Elrond protocol, the mechanism backing its massive scalability, and the benefits it offers businesses and developers.

About Elrond protocol

Elrond is a fast, secure, and scalable blockchain protocol for decentralized applications, enterprise-level use cases, and the future internet economy.

It’s an open-source transaction platform that is revolutionary in its ability to exchange, validate, and document valuable data. It’s valuable for payment transactions, contract signing, and transfer of rights. Transactions on Elrond are decentralized, which eliminates the need for intermediaries such as governments, banks, and other third-party entities.

Elrond places great emphasis on security, which is evident from its network design built to withstand significant security risks such as Sybil and nothing-at-stake attacks.

Another important aspect of the Elrond blockchain that might interest businesses and developers is that its solution for smart contracts provides an EVM-compliant computational engine to ensure interoperability in an ecosystem that is striving for interconnectivity.

Elrond takes a giant leap forward in terms of energy utilization standards by being highly energy efficient. And it owes this quality to its compatibility with commercially available hardware. Another factor that allows it to conserve energy is its consensus mechanism (Secure PoS), which has helped it earn a better eco-balance scorecard than other popular blockchains such as Ethereum.

Blockchain challenges that Elrond addresses

Blockchain’s unique capabilities make businesses keenly interested in adopting it, but concerns linked to scalability, security, and interoperability often create roadblocks.

Here are some common blockchain challenges that the Elrond blockchain overcomes with its innovative public blockchain infrastructure:

  • Lack of full decentralization: Elrond ensures full decentralization, eliminating the need for any trusted third party, hence removing any single point of failure.
  • Compromised security: Elrond ensures robust security and allows secure transactions on its platform by preventing attacks by most known attack vectors.
  • Lack of scalability: Elrond’s high scalability enables it to perform at par with many of its renowned counterparts. Elrond can perform up to 15,000 TPS, and it has six seconds of block finality time.
  • Efficiency issues: It performs all network operations with minimal energy and computational requirements.
  • Bootstrapping and storage: Elrond ensures a competitive cost for data storage and synchronization. Absence of cross-chain interoperability: The network permits unlimited communication with external protocols.

Elrond reflects a complete rethinking of public blockchain infrastructure and is specifically designed to address the above-mentioned issues. However, it’s worth noting that Elrond’s capabilities rest on two key building blocks: adaptive state sharding and secure proof of stake.

How does Elrond resolve the problem of scalability?

The three most important characteristics of a mature blockchain network are scalability, security, and decentralization. Sadly, it’s not possible to achieve all of these simultaneously with our current state of technology. For instance, an attempt to improve decentralization could negatively impact security and scalability. Also, to boost scalability, a blockchain’s security and decentralization might have to be compromised. In fact, it’s nearly impossible to attain two of these qualities without making trade-offs with the third. In technical parlance, this state of fix is referred to as a blockchain trilemma.

Elrond resolves this trilemma with its unique modus operandi. It hits all three targets with a scaling technique called adaptive state sharding and its special consensus mechanism, secure proof of stake.

These mechanisms help the platform significantly grow its throughput or transactions per second, ensuring a massive increase in scalability. Hence, understanding these technological breakthroughs is imperative to gain a deeper insight into the working of Elrond.

Let’s begin by talking about adaptive state sharding and its role in the Elrond ecosystem. We will then discuss Elrond’s consensus algorithm—secure proof of stake.

Adaptive State Sharding

Adaptive state sharding is based on the principle of division of work. And to understand it, we must first understand the following three types of sharding:

  • In-state sharding, the history and “state” of the entire blockchain system is divided among different sections or “shards” of the network. Thus, each shard on the network has its own history/ledger to store and work on, which dramatically reduces latent storage capacity.
  • Transaction sharding refers to the mapping of transactions to shards based on criteria such as a sender’s address. Each shard processes transactions in parallel with other shards. In this type of sharding, every node in the network keeps track of its entire state.
  • Network sharding manages the way nodes are grouped into shards. This type of sharding is meant for optimizing communication because messages can be sent to shards faster than to the whole network.

Adaptive state sharding resolves the problem of scalability by combining these three types of sharding and allowing parallel processing at all levels. The additional benefits it offers include improving communication within shards and boosting the overall network performance. The reason this mechanism is referred to as “adaptive” is that the total number of shards on the network is directly proportional to the number of nodes on it. As the number of nodes increases, the number of shards on the network also increases simultaneously. So no matter how large the network’s work volume grows, it will always have enough shards to handle it.

Secure Proof of Stake

Elrond’s consensus-building approach is called secure proof of stake (SPoS). It’s a modified version of proof of stake that guarantees long-term security and distributed fairness. It can maintain a high level of security and eliminate computational waste with random consensus group selection. It considers miners’ “stake” and “rating” before accepting their blocks. This selection process involves randomly sampled consensus groups and a random shuffling of nodes to different network shards to prevent collusion. Although simple, this random selection process cannot be predicted or influenced.

The components of Elrond’s architecture

Much of what Elrond is capable of stems from its intelligent design structure. The most vital components of Elrond’s architecture include the following:

Users and nodes

Transactions can be performed on the Elrond network in the form of value transfers and smart contract execution. It’s the nodes on the network that perform all these transactions. Conversely, users use the Elrond blockchain to deploy signed transactions for smart contracts’ execution or value transfers.


Validators are nodes on Elrond’s network that generate blocks and build consensus for transactions. They get rewarded for the work they do. However, they must use tokens to qualify as validators.


Shards are smaller parts of the Elrond network that aid in achieving scalability. Each shard has responsibility for a portion of the blockchain’s state.


The metachain runs on a dedicated shard and performs tasks such as authentication and finalization of shard block headers or facilitation of communication between shards.

EGLD/eGold tokens

Elrond uses EGLD (eGold), its native token, to pay for the execution of smart contracts, transactions, or rewards to validators.

Benefits of using Elrond for developing blockchain-based solutions

Swift transactions and maximum scalability

Elrond is one of the most popular and powerful blockchains that solves the issue of scaling by parallelizing transaction processing with adaptive state sharding.

The Elrond blockchain can execute transactions in near real time with over 250,000 transactions per second (Testnet results). Such speed is essential for project developers who want to scale their blockchain projects.

Improved safety

During a transaction, the data is encrypted and stored on millions of computer nodes that make up the hardware framework for the blockchain.

Nodes are updated with every new data record at the time of its creation, and this data is protected from tampering by cryptographic processes.

Elrond uses secure proof-of-stake to maximize the security of the data stored on the blockchain. Validators are randomly selected to build consensus, and the selection can be done in less than 100 milliseconds. This randomized validator selection process prevents manipulation.

Low transaction costs

To make blockchain projects more accessible to the masses and keep prices competitive, transaction costs must be low. Elrond has a clear advantage in this area with negligible transaction fees compared to other payment solutions.

Developer friendly

Elrond’s Wasm is also known as Elrond Virtual Machine. It is a unique computational engine that executes smart contracts on Elrond. The most notable characteristic of Elrond Virtual Machine is that it has Rust included in the list of languages along with C/C++ and C#. This advantage implies developers can write smart contracts in the programming language they know.
