NEW CryptoBubbles, the first dApp to run on a truly state sharded architecture
Join the conversation on:
ADAPTIVE STATE SHARDING

Comparable in throughput as to centralized counterparts.

Our architecture goes beyond state of the art and can be seen as an augmentation of the existing models, improving the performance while focusing to achieve a better nash equilibrium state between security, scalability and decentralization.

SECURE PROOF OF STAKE

Minimal energy and computational requirements.

Elrond eliminates the need for intensive PoW consensus algorithms and proposes a novel and more robust Secure Proof of Stake consensus, enhancing intra-shard communication and pruning the blockchain state to the most essential.

Read More
DECENTRALIZED

Increased security due to the randomly selected block proposer.

Elrond introduces an improvement which adds security and reduces latency, allowing each node in the shard to determine the members of the consensus group (block proposer and validators) at the beginning of a round. This is possible because the last block’s aggregated signature is used as the randomization factor.

COMMUNICATION

Decentralizing cross-blockchain operations.

The Elrond Virtual Machine’s implementation will hide the underlying architecture isolating the smart contract developers from system internals ensuring a proper abstraction layer. In Elrond, cross chain interoperability can be implemented by using an adapter mechanism at the Virtual Machine level. This approach requires specialized adapters for each chain that is non EVM compatible and wants to operate with Elrond.

Elrond "Zero to One" Testnet

The Elrond testnet has low system requirements and can run on anything from an ordinary computer to T2 medium AWS machines. 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), in 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 currently working on improving the network stack used for communication to reduce the bandwidth and network overhead within the consensus group of each shard.

Improving the performance of smart contract execution

"The basic architecture of Elrond is a plug-and-play type, where high level components connect/communicate with each other through well defined interfaces. A virtual machine which deploys and executes smart contracts in a specific language is a high level plug-able component in this architecture.

One such VM has to satisfy an interface and gets read-only access to the data existing in the blockchain through a set of hooks. Through this interface..."
