Websitehttps://elrond.com/

 Basics

"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 currently in the testnet phase." 

History

  • First was called Elrond (ERD) but changed it with its mainnet launch. From CoinDesk (31-7-2020):

"As part of the mainnet transition, Elrond said total token supply had been drastically reduced from 20 billion to just 20 million. Rather than burning tokens, Elrond is using an exchange swap where 1,000 testnet ERD tokens translate into just one token on mainnet – called Elrond Gold (eGLD)."

Audits & Exploits

  • Bug bounty program can be found here (6-12-2021), amounts as bounty are not mentioned.
  • From their docs (6-12-2021):

"Validated through multiple audits from Trial of Bits & others"

Bugs/Exploits

  • A full breakdown of the exploit can be read here (9-6-2022), with the final conclusion:

"The hacker swapped the EGLD for USDC on Maiar and tried to bridge them to Ethereum. To stop him, the Elrond team paused the necessary smart contracts and investigated."

  • The founder tweeted about the aftermath (8-6-2022):

"Nearly all of the exploited funds have already been recovered in this address: erd1pml9k2tsqsnvtmmalglt2su0sn3cguvr8e8jq0gy69zw2ldcej2qapml9a Any remaining missing funds caused by the known bug, will be covered in full by the Elrond Foundation. Third, the API send function will once again be activated in 45 min, enabling sending tokens across the Elrond web wallet and Maiar app."

  • From Blockworks (5-6-2022):

"Founder and CEO of Elrond, Beniamin Mincu, tweeted Sunday his team was investigating “suspicious activity” on Maiar and would provide an update “soon.” Blockworks has confirmed that Maiar has gone offline by way of a “scheduled maintenance” with an accompanying message on its site claiming that “operations will resume shortly.” The exchange has remained offline for more than seven hours. Smart contracts built for Maiar and deployed on Elrond were touted at the time of the launch as having undergone “rigorous auditing and formal verification.”"

Governance

Admin Keys

DAO

"The ERD token will also be used for voting and on-chain governance at a later stage, once on-chain governance is enabled."

  • Is on their roadmap for Q2 of 2020. As of 6-2022, no on-chain governance has been implemented or published about. According to the roadmap it is now scheduled for Q3 of 2022.

Treasury

"Each time a transaction happens in Elrond, a percentage of transaction fees will go to validators, another percentage will be burned, while the small remaining part will either be: a) donated to the Elrond Community Fund or b) also burned. The percentages will be released publicly in upcoming releases from the team."

Token

Private sale

  • April 2019 - May 2019, raised $1.9M.

Launchpad Sale

  • Conducted in June 2019 for a total raise of 3,250,000 USD on the Binance Launchpad.

Token allocation

  1. "Launchpad sale tokens comprise 25% of total supply.
  2. Private sale tokens comprise 19% of total supply.
  3. Team tokens comprise 19% of total supply.
  4. Reserve tokens comprise 17% of total supply.
  5. Advisors received 2.5% of total supply.
  6. Ecosystem Rewards tokens comprise 7% of total supply.
  7. Marketing tokens comprise 8.5% of total supply.
  8. Community tokens comprise 2% of total supply."

Utility

  1. "The ERD token is used to stake and participate in the Secure Proof of Stake consensus of the network.
  2. In addition, the ERD token is used to pay for transactions, storage fees, and as gas. The token also serves as rewards to the SPoS validators.
  3. The ERD token will also be used for voting and on-chain governance at a later stage, once on-chain governance is enabled.
  4. In Elrond, rewards are paid through an emission of ERD defined in the protocol. The majority of all newly issued ERD will go to validators, while a very small part will go to a reserve pool. The reserve pool will be used to fund development and ecosystem expansion, increasing the security and value of the network in the long term.
  5. Each time a transaction happens in Elrond, a percentage of transaction fees will go to validators, another percentage will be burned, while the small remaining part will either be: a) donated to the Elrond Community Fund or b) also burned. The percentages will be released publicly in upcoming releases from the team."

Token Details

“One of the most attractive features of Elrond is that smart contract authors get 30% of the gas utilized by their contract as royalties, without the caller having to pay more. Elrond smart contracts are upgradeable, which will definitely make life easier for any project’s lifecycle.”

Tech

"The Elrond Virtual Machine is a dedicated smart contract execution engine built on WASM. It expands the family of languages available to smart contract developers to include Rust, C/C++, C#, Typescript. This means you can write smart contracts in whichever language you’re familiar with, compile it of WASM and easily debug its WAT human readable format."

  • Capacity (TPS): 10K (20-6-2019), up to 250,000 (31-07-2020), according to the website (6-12-2021) they now claim 15,000 TPS (scales > 100kTPS), 6s latency, also bumping up the below mentioned latency.
  • Latency: 5-seconds (20-6-2019). NEAR says it is 6-12 seconds (17-10-2022).

How It Works

"Elrond sharding mechanism is called Adaptive State Sharding, which insists of network sharding, transaction sharding & state sharding. The mechanism is already live and the network is currently running with 4 shards: 3 execution shards and 1 coordination shard “metachain”. “Metachain is the blockchain that runs in a special shard, where the main responsibilities are not processing transactions but notarizing and finalizing the processed shard block headers”."

  • Combines, stake, reputation & random selection.
  • From Binance Research (20-6-2019):
  1. "State sharding (transaction, data & network sharding); adaptivity through shard merges and shard splits
  2. Consensus in two communication rounds with modified Boneh–Lynn–Shacham ("BLS") multi-signatures
  3. High resiliency to malicious attacks due to intra and cross shard node reshuffling
  4. Secure randomness beacon with BLS signing
  5. Smart contracts on a state sharded architecture with balanced load on shards
  6. Fast finality for cross shard transactions (seconds)"

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.

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"

Fees

Upgrades

Staking

  • Has 3200 live nodes, with 55 in queue (6-12-2021) and 56% staked.
  • There are now more than 2,000 validators with 50% locked in staking. (11-2020).
  • Has 39% staked, according to their website (6-5-2020).

Metachain

"The Metachain is the blockchain that runs in a special shard, where the main responsibilities are not processing of transactions, but notarizing and finalizing the processed shard block headers, facilitating communication between shards, storing and maintaining a registry of validators, triggering new epochs, processing fisherman challenges, rewarding and slashing."

Interoperability

"Cross-Chain Interoperability For Elrond DeFi Via Fire Protocol"

Other Details

  • From this blog (9-8-2019):

"Elrond is also looking to provide cross-chain interoperability. The Elrond Network has plans to allow full communication between various external services, beginning with the implementation of the Elrond Virtual Machine (EVM). This virtual machine will support smart contracts written in Solidity, allowing users to create secure transactions between Elrond, Ethereum and other ERC-20 tokens without using an exchange. The Elrond VM will also feature an adapter mechanism that will allow communication with other chains that include adapters to work with Elrond."

Pros and Cons

Pros

Competition

"In terms of scalability, Ethereum 2.0 will have a hard job keeping up, as the project achieved 260,000 transactions per second on its testnet, thanks to its adaptive state sharding mechanism.

According to Daniel Serb, head of business development at Elrond, the platform’s approach to sharding is comparable with Ethereum 2.0. Both platforms partition the network nodes, transactions and state of the blockchain to achieve high throughput. However, Elrond starts with a fixed number of shards that can process 15,000 transactions per second. However, the protocol allows for the number of shards to increase dynamically, depending on traffic. In contrast, the number of shards on Ethereum is fixed at 64. Developers may find that building on Elrond is more rewarding in the long term in comparison with Ethereum, as Serb told Cointelegraph: 

“One of the most attractive features of Elrond is that smart contract authors get 30% of the gas utilized by their contract as royalties, without the caller having to pay more. Elrond smart contracts are upgradeable, which will definitely make life easier for any project’s lifecycle.”"
