Cronos blockchain is empowered by the Crypto.com company.

Its core has been built on Cosmos SDK technology, which is fully compatible with EVM (Ethereum Virtual Machine).

The chain is secured by the Ethash function.

In short, this function is a Proof of Work (PoW) consensus protocol modified from Dagger-Hashimoto.

As part of Ethash requirement, hashing process output should create a hash value lower than the threshold.

The virtual machine will increase, or decrease the threshold to maintain a stable mining rate.

At the time of this article, Cronos is running on ‘Huygens’ version updated at the block height of 2,693,800.

The new update brings EIP-1559 implementation to the chain aside from major performance improvements.

Average Cronos block time is approximately 5.7s.

The chain offers a permissionless and open-source environment for developers to build application using Solidity, Typescript, and IPFS.

Cronos tends to focus on DeFi apps.

Recently, this Layer 1 also shifts its attention to GameFi and Web3.

Cronos Node

Cronos Node architecture is quite different from others.

It has been designed to optimize mobile payment experience, which achieves through the use of several different node layers.

Council Cronos Node

Council Node receives processing fees, manages transactions, validations and settlements.

They are compensated for each processed transaction.

Acquirer Cronos Node

Acquirer node provides escrow services and manage settlements between merchant and customer.

It also verifies transactions from different merchants.

Acquirer gets rewards based on the amount of processed transactions.

Settlement Agent Cronos Node

Settlement Agent Node provides CRO tokens to get stable currencies in return.

It ensures merchants have full access to stable conversion rate options post-settlement.

Settlement Agent is compensated with a flat-rate fee on each fiat payout.

Community Cronos Node

Community node connects customer and merchant in direct transactions.

Establish Cronos Node

Since the launch of Huygens, all Cronos Nodes must update their Cronos Mainnet Binary to version 0.7.0

To dive deeply into the process, please check their documentation.

CRO Token

CRO token plays in an important role in the Cronos blockchain as the native token.

The token is the only payment for gas fee within the network.

It helps to distribute network resources properly.

About Cronos RPC

Cronos RPC is needed for users to fully experience the network.

It grants an easy access to Cronos wallet and to Dapps on the chain.

Cronos Faucet

Cronos Faucet enables users to claim free CRO tokens on the testnet environment.

Testnet CRO (tCRO) has no actual market value, but for testing purposes only.

Please keep in mind that tCRO token cannot be transferred to the mainnet in anyways.

To access the Cronos Faucet, please visit https://cronos.org/faucet
