logoElrond (EGLD)

A Scalable Value Transfer Protocol For The Digital Economy.
  • Elrond is a high-throughput public blockchain focused on providing security, efficiency, scalability, and interoperability by employing two key elements: Adaptive State Sharding and a new Secure Proof of Stake ("SPoS") consensus mechanism.
  • Elrond's blockchain protocol for smart contracts & dApps can process over +10k transaction per seconds with low block times (5s), negligible transaction fees, and with fast finality for cross shard transactions in a matter of seconds.
  • The Adaptive State Sharding, works via shard merges & splits for unlimited scalability, and uses a fully sharded Architecture, which includes state, transactions, and network. This architecture is deemed highly resilient against malicious attacks due to validators shuffling between shards.
  • Elrond features smart-contract royalties, where 30% of the fees can be reallocated to the smart contract author.
  • EGLD is the native asset of Elrond and is used to pay for transaction fees and the cost of deploying dApps on the network, along with rewards for various contributions to the network.

1. What is Elrond (EGLD)?

Elrond is a high-throughput public blockchain focused on providing security, efficiency, scalability, and interoperability by employing two key elements: Adaptive State Sharding and a new Secure Proof of Stake ("SPoS") consensus mechanism.

Elrond's testnet is already live and can process upwards of 10K TPS, with 5-second latency and minimal cost (based on 5 shards). The Project aims to be a platform for easy deployment of programmable money and dApps, thus becoming the backbone of an open, permissionless, borderless, globally accessible internet economy.

Elrond's goal is to be a high throughput, fast transaction speed, and low transaction cost platform, allowing efficient and competitive dApp user experiences in real world use cases.

Elrond believes that its high scalability, fast transaction speed, and low transaction cost makes it well-suited for machine-to-machine transactions and the IoT economy.

Some of its key elements include:

  • Elrond is a high-throughput public blockchain aimed at providing security, efficiency, scalability, and interoperability via Adaptive State Sharding and a Secure Proof of Stake consensus mechanism.
  • Elrond is built by a team of entrepreneurs, engineers and researchers with technical experience at Google, Microsoft, Intel, NTT, a PhD in Computer Science ("CS"), and blockchain backgrounds, including being previously part of the NEM core team.
  • Elrond is currently in the testnet phase and aims to be a platform for easy deployment of programmable money and dApps, thus becoming the backbone of an open, permissionless, borderless, globally accessible internet economy.

Elrond is a complete redesign of blockchain architecture with the aim to achieve global scalability and near instant transaction speed. Elrond focuses on combining these key innovations:

  • State sharding (transaction, data & network sharding); adaptivity through shard merges and shard splits.
  • Consensus in two communication rounds with modified Boneh–Lynn–Shacham ("BLS") multi-signatures.
  • High resiliency to malicious attacks due to intra and cross shard node reshuffling.
  • Secure randomness beacon with BLS signing.
  • Smart contracts on a state sharded architecture with balanced load on shards.
  • Fast finality for cross shard transactions (seconds).

The Elrond mobile app Maiar offers internet users an intuitive first-time experience with blockchain technology, offering progressive security and a gamified approach to unlocking more useful features.


The Elrond economic model has a capped supply and decreasing issuance, furthering scarcity with adoption. The token is named eGold (EGLD) to convey the notion of a digital store of value for the next billion users.

The Elrond Network is certified carbon negative by Offsetra, as it offsets more CO2 than the network is accountable for.

2. Blockchain and network data

The blockchain has low system requirements and can run on anything from an ordinary computer to T2 medium AWS machines.

The blockchain features epochs of ~24 hours and rounds of ~5 seconds. All the validators in Elrond's network will be split among multiple shards, where they will only have to synchronize the state for the current shards and process transactions only for their current shard. In order to prevent collusion amongst validators, up to ⅓ of the validators in a shard will be reshuffled to other shards at the end of every epoch. Liveness is not affected by this because the fast state synchronization for the newly reshuffled validators needs to synchronize only the state for the current epoch (~24 hours timeframe), while the remaining ⅔ of the unshuffled validators in the shard can still process transactions.

Each shard will consist of 400-600 validators and have a separate chain, accounts and application state. The consensus group (currently set to be n=63) changes every round based on a randomness seed stored in the previous block's header. These validators in the consensus group need to agree on the proposed block in every round of every epoch.

Based on the randomness source in the previous block, n validators are chosen using a deterministic function. Every other validator in the shard can compute the n validators and verify the correctness of this nomination. The first selected validator will be the block proposer for the current round.

The block proposer signs the previous randomness source with a BLS single signature to generate the next randomness source, creates a block with transactions, adds the new randomness source in the block header and broadcasts this block to consensus group members.

Each member validates the block, also validating that the new randomness source is a signature verifiable with the leader's public key on the old randomness source. If both are valid, it creates a BLS signature on the proposed block and sends this back to the leader.

The block proposer selects from among all received signatures, creating a subset of at least ⅔*n + 1 signatures, and creates a bitmap for his selection, where B[i]=1 if the ith member of consensus group was selected and B[i]=0 otherwise. The proposer then aggregates the signatures and attaches the bitmap and signature to the block. It must also sign the end result to "seal" the configuration for (B[ ], aggSig) before propagating the resulted block through gossip inside the shard.

Cross-shard transaction processing

For an in-depth example of how the cross-shard transactions are being executed and how the communication between shards and the metachain occurs, the entire process is illustrated using the simple two shard case and the metachain as shown in the figure below.


The strategy for processing one cross-shard transaction is to use an asynchronous model. Validation and processing is done first in the sender's shard, notarized in the metachain and then finalized in the receiver's shard.

  • Step 1: The cross-shard transactions are first processed and added to a block in the sender's shard. The transaction value has thus been deducted from the sender's account.
  • Step 2: The block header is sent to the metachain where it is added to a metablock.
  • Step 3: The metablock arrives in the destination shard and then needs to be processed there. The destination shard requests the transaction from the sender's shard (if missing).
  • Step 4: The transaction is then added in a block in the destination shard and the block header is sent to the metachain. As a result, the transaction value has been added to the recipient account.
  • Step 5: The metachain notarizes the block that includes the processed transaction in the destination shard and the transaction is then finalized.

This iteration consists of static state sharding, secure proof of stake consensus, Schnorr signature for transactions, BLS signatures for random seed generation, and modified BLS multisig for blocksigning.

Metrics that are being monitored to check improvement of the network include: latency, bandwidth limitations, running each validator node on a separate machine with very limited compute power (average dual-core CPU with 4GB of memory), and different geographic locations.

Key stats for the current testnet are as follows:

  • Sharding setup: 5 Shards + Metachain
  • Nodes: 500 x AWS T2.medium (validator nodes) and AWS 12 x T2.large (observer nodes)
  • Nodes per shard: 83
  • Consensus: BLS round every 6 seconds on each shard
  • Consensus size: 63 nodes per shard
  • Max-Blocksize: ~800KB
  • Peak-TPS: ~12,500

The team is working on improving the network stack used for communication to reduce the bandwidth and network overhead within the consensus group of each shard.

Another improvement from the initial prototype architecture, has been upgrading the consensus model to reduce the number of communication rounds between consensus groups on each shard from 5 to 2.

An illustration of Elrond's latest implementation of Secure Proof of Stake is as follows:


An illustration of Elrond's Adaptive State Sharding Approach is as follows:


The upcoming testnet releases will include a public adversary game (Battle of Stakes) that will combine all the metrics together and will produce the highest level of stressing the protocol, allowing us to improve and find new opportunities for improvement. New stress results will follow in the upcoming weeks.

Development toolkit

Writing Smart Contracts on Elrond is made easy by frameworks in Rust, C, C++ and other languages compiling down to WASM. The erdpy back-end is a complete CLI & Python SDK for building, deploying and interacting with Smart Contracts. The erdjs framework allows for front-ends to be deployed using TypeScript & JavaScript and makes testing easy with tools such as Mocha.

The Elrond Integrated Development Environment is available via the Microsoft marketplace as a Visual Studio Code extension. Its integration with the SC framework allows developers to focus solely on smart contract logic and handles boilerplate code, dependencies and inheritances, while offering a transparent debugging interface.

By leveraging social mining through its community platform, the Elrond team employs an open bounty and reputation system to continuously engage its community and grow the Elrond ecosystem. Through this system, the Elrond team has focused on constant and inclusive interaction, and is regularly devising campaigns to consolidate the community.

The team is also constantly engaging with key opinion leaders from various countries, to grow outreach and raise awareness about Elrond.

  1. At a rather early stage of the project, Elrond open sourced their prototype, starting a conversation with developers about the latest innovations in the space.
  2. Releasing the testnet wallet gave everyone the opportunity to interact directly with the Elrond blockchain, and provide useful feedback.
  3. The Battle of Stakes program, slated to be released in Q3 2019, is designed to encourage testnet participants to collude and take over the network.
  4. Through hackathons, the Elrond team opens up the opportunity for enterprises and developers to fully test the network and complete challenges.
  5. At a later stage, the Elrond team intends to launch a few bug bounty programs to speed up development.

The team plans to continue their AMA series targeting specific regions of the world. Next AMAs will focus on Asia, Russia, and Central Europe, and will be conducted in multiple languages.

Growth strategy through events and conferences

Elrond has been present at a few significant conferences and technical events such as SFBW, Devcon, Blockchain Malta Summit, and have also held a number of local meetups to get first hand feedback from the community.

More events (to be announced) are lined up where the team will showcase their testnet demo and discuss other partnership opportunities.
