The Cronos Community Defined

Earlier than we present you how you can join a dapp to Cronos, we must offer you some fundamental info concerning this improvement chain. So, let’s use this part to briefly clarify what Cronos entails. 

The Cronos community was launched in 2021. Since then, it’s been working parallel with the Crypto.org blockchain. Additionally, Cronos is intently related with Crypto.com; in spite of everything, it powers that trade’s “Pay” function. Moreover, it’s price stating that Crypto.com has been round since 2016. Furthermore, that is the group behind each the Crypto.org and Cronos blockchains.

Additionally, remember that the Cronos blockchain is EVM-compatible. It helps inter-blockchain communications (IBC) amongst networks based mostly on the Cosmos SDK. In spite of everything, Cronos was constructed on Cosmos, and, in flip, Cronos is appropriate with Ethereum and Cosmos-based ecosystems. Therefore, this excessive diploma of interoperability allows devs to port Ethereum dapps and good contracts with out breaking a sweat. 

Moreover, you might need heard of “CRO” earlier than. The latter serves as the bottom settlement foreign money of the Cronos community. Nonetheless, CRO was primarily (and nonetheless is) the native token of the Crypto.org chain. Accordingly, CRO constitutes a vital part of each the Crypto.org and Cronos ecosystems. 

So far as the consensus mechanism goes, Cronos depends on the proof-of-stake (PoS) idea. Because of this Cronos community validators stake a part of their property, which is used to validate transactions. This additionally enforces good conduct of community members. Nonetheless, it’s price stating that the principle advantage of utilizing PoS is scalability. In spite of everything, that’s one of many primary causes Ethereum transitioned from its proof-of-work (PoW) mechanism to PoS (The Merge). After all, PoS can be extra pleasant to the surroundings. 

Why Constructing and Connecting Dapps to the Cronos Community?
