It is a [blockDAG](https://en.wikipedia.org/wiki/Directed_acyclic_graph) as a proof-of-work cryptocurrency with instant confirmations and sub-second block times with a work-in-progress (WIP) attempt to implement smart contracts as a side-chain. It is based on [the PHANTOM protocol](https://eprint.iacr.org/2018/104.pdf), a generalization of Nakamoto consensus. ## Overview Karlsen is a fork of [Kaspa](https://github.com/kaspanet/kaspad) introducing a GPU-centric fork as a solution to the dominance of ASIC mining farms, aiming to empower small-scale miners and enhance decentralization. We focus on bridging the gap between blockchain technology, decentralized finance and the real world of payment systems and traditional finance. With Kaspa, our approach is one of friendly cohabitation. We operate under the same protocol, enjoy similar advantages, and face unidentified issues. Any significant improvements that need to be made in the primary codebase will be shared back. ## Small Scale Miners The Karlsen Network team believes in decentralization and small-scale miners. We will ensure long-term GPU-friendly mining. ### Hashing Function We initially started with `kHeavyHash` and `blake3` modifications on-top. This algorithm is called `KarlsenHashv1`. However `kHeavyHash` and `blake3` are not future proof in ASIC resistence. Therefore we've launched already our `testnet-1` with [FishHash](https://github.com/iron-fish/fish-hash/blob/main/FishHash.pdf). It is the worlds first implementation of FishHash with Golang in a 1bps blockchain. `KarlsenHashv1` is currently used in [mainnet](https://github.com/karlsend/PYVERT/testfork/karlsend/releases/tag/v1.1.0) and can be mined using the following miners maintained by the Karlsen developers: * Built-in CPU miner from `karlsend` * Karlsen [GPU miner](https://github.com/karlsend/PYVERT/testfork/karlsen-miner) as reference implementation of `kHeavyHash` with `blake3`. The following third-party miners are available and have added `KarlsenHashv1`: * [lolMiner](https://github.com/Lolliedieb/lolMiner-releases) * [Team Red Miner](https://github.com/todxx/teamredminer) * [SRBMiner](https://github.com/doktor83/SRBMiner-Multi) * [BzMiner](https://github.com/bzminer/bzminer) * [Rigel](https://github.com/rigelminer/rigel) * [GMiner](https://github.com/develsoftware/GMinerRelease) `KarlsenHashv2` is currently being investigated and tested in [testnet-1](https://github.com/karlsend/PYVERT/testfork/karlsend/releases/tag/v2.0.0-testnet-1-fishhash) and can be mined using the following miners maintained by the Karlsen developers: * Built-in CPU miner from `karlsend` * Karlsen [GPU miner](https://github.com/wam-rd/karlsen-miner/releases/tag/v2.0.0-alpha) as bleeding edge and unoptimized reference implementation of FishHash. There are no third-party miners available as of now. ## Smart Contracts The Karlsen Network team is launching an R&D project to connect the Karlsen blockchain with other blockchain ecosystems using a smart contract layer based on the [Cosmos SDK](https://v1.cosmos.network/sdk). This initiative aims to enhance interoperability, efficiency, and innovation in the blockchain space. By leveraging the Cosmos SDK's advanced features, we'll facilitate seamless transactions across different networks, offering new opportunities for users and developers. ### Cosmos Hub [Cosmos](https://cosmos.network/) is a highly attractive ecosystem due to its innovative approach to blockchain interoperability, scalability, and usability. By enabling different blockchains to seamlessly communicate and exchange value, Cosmos opens up vast opportunities for businesses and developers to build and deploy decentralized applications that can operate across multiple blockchain environments. This interoperability fosters a more connected and efficient digital economy, potentially driving adoption and usage across various sectors, including finance, supply chain, and beyond. By connecting to Cosmos, we will open the door of a web3 ecosystem connected to a complete network of other blockchain project, making Karlsen Network more competitive and adaptable in the rapidly evolving landscape of decentralized technologies. ### Karlsen Sidechain The creation of the Karlsen [sidechain](https://github.com/john-light/sidechains) with fast transaction times, smart contract capabilities, and a dual coin model, designed to integrate seamlessly with the Cosmos ecosystem and utilize the Karlsen (KLS) across all interconnected platforms, signifies a strategic advancement in Karlsen Network. This sidechain will not only enable quick and efficient inter-blockchain transactions but also support complex decentralized applications through its smart contract functionality. The ability to use Karlsen (KLS) across the entire ecosystem will ensure a unified and streamlined user experience, promoting greater adoption and utility within the Cosmos network. This sidechain aims to enhance scalability, foster innovation, and provide a flexible and user-centric blockchain solution that meets the diverse needs of developers, users, and investors within the Cosmos ecosystem. ## Installation ### Install from binaries Pre-compiled binaries for Linux `x86_64` and `aarch64`, Windows `x64` and macOS `x64` as universal binary can be downloaded at: [https://github.com/karlsend/PYVERT/testfork/karlsend/releases](https://github.com/karlsend/PYVERT/testfork/karlsend/releases) ### Build from Source Go 1.19 or later is required. Install Go according to the installation instructions at [http://golang.org/doc/install](http://golang.org/doc/install). Ensure Go was installed properly and is a supported version: ```bash go version ``` Run the following commands to obtain and install karlsend including all dependencies: ```bash git clone https://github.com/karlsend/PYVERT/testfork/karlsend cd karlsend go install . ./cmd/... ``` Karlsend (and utilities) should now be installed in `$(go env GOPATH)/bin`. If you did not already add the `bin` directory to your system path during Go installation, you are encouraged to do so now. ### Getting Started Karlsend has several configuration options available to tweak how it runs, but all of the basic operations work with zero configuration. ```bash karlsend ``` ## Discord Join our discord server using the following link: [https://discord.gg/ZPZRvgMJDT](https://discord.gg/ZPZRvgMJDT) ## Issue Tracker The [integrated github issue tracker](https://github.com/karlsend/PYVERT/testfork/karlsend/issues) is used for this project. ## Documentation The [documentation](https://github.com/karlsend/PYVERT/testfork/docs) is a work-in-progress. ## License Karlsend is licensed under the copyfree [ISC License](https://choosealicense.com/licenses/isc/). # test1
