Karlsen Sidechain devnet launch

The Karlsen Dev Team is excited to announce the official launch of the Karlsen sidechain devnet, built on the Cosmos SDK.
The sidechain will introduce smart contracts to the Karlsen network and establish cross-chain connectivity with multiple blockchains, including kaspa.


The Karlsen Sidechain features native cross-chain smart contracts, a concept inspired by the ZetaChain project. These smart contracts allow developers to orchestrate assets and execute actions across various chains. For example, a single transaction could move an ERC-20 token on Ethereum and then transfer KLS or KAS between addresses. This capability enables developers to create seamless, multi-chain applications that unlock new opportunities in DeFi, NFTs, gaming, DAOs, identity, and more.

Our current focus includes integrating Karlsen with Kaspa and ZetaChain (already connected to Bitcoin, Ethereum, BNB Chain and Polygon), with further integrations planned through strategic partnerships.


Development Status:
* We have launched the devnet for our sidechain.
* Work is ongoing to implement Karlsen and Kaspa clients and signers.
* Our immediate goal is to establish functioning observer and signer nodes for Karlsen, followed by similar deployments for Kaspa on the devnet.


Upcoming Roadmap Events:
* The KLS first halving is imminent, reducing the reward from 50 to 44 KLS per block.
* Validation of the testnet featuring the new GPU-friendly algorithm, KarlsenHashV2.
* Deployment of Karlsen Mobile on Android store
* Enhancements and optimizations to strengthen our ecosystem's infrastructure.
