  • 2021-09-25  KAK Horizon is officially launched

    KAKLAB's test network has been officially closed. At the same time, the test mainnet KAK Horizon is launched. Users can access KAK Horizon and related interfaces through www.kaklab.com. At the same time, users can make suggestions during the use of the KAK Horizon to jointly improve the development of the KAKLAB ecosystem.

  • 2021-09-18  KAKH is listing on DGalaxy

    KAKH is listing on the DGalaxy exchange. KAKH is the BSC(Binance Smart Chain) cross-chain token (BEP20, smart contract 0xbe9beb51820179487d422668fcb6e2595d6901a6).
    After the official launch of the KAK Horizon test mainnet, the test mainnet token KAKH will be issued. Then users can participate in node mining after the KAKHs on the BSC are exchanged for the KAKHs of the test mainnet through the official cross-chain nodes. In the future, according to the needs of ecological development, we will issue KAKH on other cross-chain tokens such as Ethereum.

  • 2021-09-17  KAK Horizon will be launched on September 25

    After consideration, KAKLAB finally decided to postpone the launch of the KAKLAB mainnet. At the same time, KAKLAB will launch the test mainnet on September 25th, and the mainnet will be officially launched 2 months later.

    The KAK Horizon test mainnet will not be equipped with smart contracts. It will establish its own test application ecosystem on other mainnets such as ETH, BSC, etc., and complete the cross-chain gateway when the test mainnet is launched. KAKLAB mainnet will have its own smart contract and will migrate users in the test mainnet to the mainnet.

    At the same time, the test mainnet will use an economic game mechanism to replace meaningless packaging. When the user completes the pledge, we will assume that the user has provided the corresponding storage space, and send the storage demand from the system. Once the user client fails to store within the specified time, it will be punished by deduction of the pledged assets.

    If these mechanisms are successful in the mainnet testing, we will migrate these mechanisms to the mainnet when the official mainnet is launched. The token of KAK Horizon is KAKH, a total of 100 million will be issued, of which:

    1. 90 million will be produced through mining, with 3 years as half-life period, that is, 45 million will be produced in the first three years, 22.5 million will be produced in the second three years, and so on;
    (1) 15% will be the POS output from validator nodes;
    (2) 70% will be the output from file storage nodes;
    (3) 15% will be the output from cross-chain DeFi, NFTFi, GameFi and other methods.

    2. The last 10 million will be allocated according to the following plan
    (1) 10% for the founding team, which will be unlocked in 36 months in equal proportions;
    (2) 10% for communities, and the reward distribution system will be jointly decided by HyperFund and KAKLAB.
    (3) 40% lock-up ecological reward for all teams that provide DeFi, NFTFi, and GameFi solutions. This part will be unlocked for 12-36 months according to the code quality, and the reward distribution system will be jointly decided by HyperFund and KAKLAB
    (4) 20% held by the HyperFund will be put into the market to quickly establish the infrastructure
    (5) 20% will be locked up as cross-chain gateway reserve, which will be unlock in 12-36 months according to the project progress. It will be used for the issuance of KAKH on other mainnet cross-chain, and the ecological construction of DeFi, NFTFi, and GameFi in multiple public chains. The process will be jointly supervised by HyperFund and KAKLAB.

  • 2021-09-15   KAK Horizon Economic Model and Mapping Airdrop Plan

    KAKLAB's test mainnet KAK Horizon will use KAKLAB's economic model plan, but some adjustments will be made:

    1. The POS output of validator nodes is 15%;

    2. The output of file storage nodes is 70%;

    3. Cross-chain DeFi, NFTFi, GameFi and other methods is 15%;

    The KAK Horizon cross-chain gateway will be launched when the test mainnet is officially launched, and applications such as DeFi, NFTFi, GameFi, etc. will be gradually deployed on it. KAK welcomes communities to provide suggestions or contribute code to improve the application ecosystem.

    After KAKLAB is officially launched on the mainnet, it will map the airdrop to the same mainnet address according to the current amount of KAKH of the miner node. The airdrop part will be locked for 540 days. During the lockup period, miner nodes can obtain output rewards through storage mining after packaging files, and the rewards will be issued in accordance with the rules of the main network. After 540 days, the locked airdrop will be unlocked at 16.7% per month.

  • 2021-09-13   KAKLAB and HyperFund have reached an agreement to develop KAKPOOL and KAK Horizon

    KAKLAB and HyperFund have reached an agreement to develop KAKPOOL and KAK Horizon mainly for customers in Asia, Europe, North America and other regions. At the same time, it establishes server clusters around the world and enhance user participation to explore more for the development and application of blockchain technology, and create more value for KAKLAB and KAK Horizon ecology.

    KAK Horizon is the main test network of KAKLAB invested by HyperFund. KAK Horizon will be operated independently with its original asset KAKH. At the initial stage, KAK Horizon will use independent economic models and storage solutions to interact with major main chains through cross-chain gateways. and create application ecosystems on multiple main networks, providing a solution for the ecological construction of KAKLAB Protocol (smart contract stage) and seed communities.

    1. KAK Horizon will use a brand-new storage mechanism and economic model, replacing economic games with invalid packages to realize mining on other main networks through DeFi, GameFi, etc.

    2. KAK Horizon will also set up an official cross-chain gateway with 1:1 lock position on the test mainnet, and conducts corresponding issuance on other mainnets, and KAKH produced on other mainnets through DeFi, GameFi, etc. can be exchanged in KAK Horizon through the cross-chain gateway.

    3. The KAK Horizon testnet will recruit ecological nodes, who can participate in the early ecological construction of KAK Horizon, including verification nodes for block generation, storage nodes, DeFi, GameFi ecosystems, etc.

    4. KAKHs produced by the KAK Horizon testnet will be mapped to the KAKLAB mainnet, but KAKs produced through mapping will implement a strict lock mechanism to ensure the healthy development of the KAKLAB mainnet ecosystem. The specific mapping rules will be Announced later.

    Guide to Install KAK Test Node

    Test Range
    KAK test nodes use POS consensus to generate blocks, including voting and withdrawal.

    Test Address
    KAK Browser :kakscan.kaklab.com
    KAK Test :Wallet wallet-en.kaklab.com
    GitHub Test Code Downloading:https://github.com/KakLab/kak-code.git

    1. System Requirements

    The minimum requirements for running KAK system:

    Linux or Macos. Windows is not supported.
    8-core CPU, KAK requires a lot of HASH operations, so CPUs with SHA Extensions instruction set can speed up operation.
    Memory: 32G
    It estimates that several gigabytes of blockchain data will be generated every day in KAK system, so a full-data node currently requires a hard disk with at least 2T volume, and SSD is recommended.

    2. Compilation preparation

    The golang and rust libraries are mainly used in the compilation process of KAK system, so you need to install the corresponding programming languages.
    In particular, if you are in mainland China, you need to set up a golang agent library.
    export GOPROXY=https://goproxy.cn
    IPFS proxy :
    export IPFS_GATEWAY=https://proof-parameters.s3.cn-south-1.jdcloud-oss.com/ipfs/

    Different system supportArch:

    sudo pacman -Syu opencl-icd-loader gcc git bzr jq pkg-config opencl-icd-loader opencl-headers opencl-nvidia hwloc

    sudo apt install mesa-opencl-icd ocl-icd-opencl-dev gcc git bzr jq pkg-config curl clang build-essential hwloc libhwloc-dev wget -y && sudo apt upgrade -y

    sudo dnf -y install gcc make git bzr jq pkgconfig mesa-libOpenCL mesa-libOpenCL-devel opencl-headers ocl-icd ocl-icd-devel clang llvm wget hwloc libhwloc-dev

    sudo zypper in gcc git jq make libOpenCL1 opencl-headers ocl-icd-devel clang llvm hwloc && sudo ln -s /usr/lib64/libOpenCL.so.1 /usr/lib64/libOpenCL.so

    Amazon Linux2:
    sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm; sudo yum install -y git gcc bzr jq pkgconfig clang llvm mesa-libGL-devel opencl-headers ocl-icd ocl-icd-devel hwloc-devel


    KAK system needs support from rust. The installation method:

    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

    The access speed of rust's official source is relatively slow. You can replace it with a domestic source. Modify the ".cargo/config" file in the user's root directory into:

    [source.crates-io] registry = "https://github.com/rust-lang/crates.io-index" replace-with = 'sjtu' [source.sjtu] registry = "https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index"


    KAK is mainly written in golang who requires version 1.16.4 or newer:
    wget -c https://golang.org/dl/go1.16.4.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local

    Set environment variables:
    echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc && source ~/.bashrc

    3. Compile

    Download the source code from KAK official website:

    git clone https://gitee.com/ka-klab_1/kak-code.git cd kak-code

    If your CPU supports SHA Extensions, you need to set environment variables to support this extension:

    export RUSTFLAGS="-C target-cpu=native -g" export FFI_BUILD_FROM_SOURCE=1

    Some old Intel or AMD processors do not have ADX instruction set, which will cause panic of KAK. Use the following settings to fix this problem:


    Compile make clean
    make 2k

    If there is no error, the KAK program will be compiled in the cmd directory: lotus、lotus-miner、lotus-worker、lotus-wallet、lotus-gateway

    4. GPU Support

    GPU can improve the computing efficiency of the P2 and C2 stages, as well as the efficiency of zero-knowledge proof, so it is recommended to use GPU as an aid.

    Known supported GPU list:

    Device Name Cores Comments
    Quadro RTX 6000 4608
    TITAN RTX 4608
    Tesla V100 5120
    Tesla P100 3584
    Tesla T4 2560
    Quadro M5000 2048
    GeForce RTX 3090 10496
    GeForce RTX 3080 8704
    GeForce RTX 3070 5888
    GeForce RTX 2080 Ti 4352
    GeForce RTX 2080 SUPER 3072
    GeForce RTX 2080 2944
    GeForce RTX 2070 SUPER 2560
    GeForce GTX 1080 Ti 3584
    GeForce GTX 1080 2560
    GeForce GTX 2060 1920
    GeForce GTX 1660 Ti 1536
    GeForce GTX 1060 1280
    GeForce GTX 1650 SUPER 1280
    GeForce GTX 1650 896
    gfx1010 2560 AMD RX 5700 XT
    gfx906 7400 AMD RADEON VI

    If your GPU is not in the list, you can test whether it supports it in setting:
    Take the 1536 core of the GeForce GTX 1660 Ti as an example:
    export BELLMAN_CUSTOM_GPU="GeForce GTX 1660 Ti:1536"
    Then recompile the node and run the test.
    ./lotus-bench sealing --sector-size=2KiB
    During testing, use tools such as nvtop to observe whether the GPU is involved in the calculation process. If it participates in, it means that the GPU is successfully enabled.

    5. Deployment and running

    Main node

    Run node:
    lotus daemon --nosync

    Synchronize node:
    lotus sync wait

    The packaged blockchain data, which can be downloaded to speed up the synchronization process, will be added later.

    lotus daemon stop


    Initialize the miner:
    lotus-miner init --sector-size=512MiB

    After creation, run the miner:
    ./lotus-miner run

    Voting: voting pledge unit: KAK
    lotus-miner vote send

    Voting redemption: voting redemption unit: KAK
    lotus-miner vote withdraw

    Check the status of miners: you can see the current closing and pledge.
    ./lotus-miner info

  • 2021-09-06   Tips for Participating in KAKLAB Test

    Please pay attention to the announcement of KAKLAB official website (www.kaklab.com) to obtain the installation package of test file and the faucet address.

    1. The first stage of KAKLAB development work has been completed. The main content is the separation of POS validator nodes and POST storage nodes. Users can get Staking rewards through block generation after pledging KAKs to POS nodes, or get KAK storage rewards through data packaging and storage.

    2. After the first stage of the mainnet is launched and works well, we will process R&D and testing of the second stage, the main content of which is to equip virtual machines and smart contract development tools.

    3. After the first two stages are fully completed, KAKLAB will fully support NFT and Metaverse, including metadata storage, digital asset issuance and circulation, and cross-chain transfer.

    4. The output of KAK is determined in the following three ways:
    1)through POS validator nodes, accounting for 20% of the total output;
    2)through storage nodes, accounting for 20% of the total output;
    3)through and GameFi and DeFi, accounting for 20% of the total output.

    5. The related installation and configuration files, browsers, and light wallets of KAKLAB testnet are ready. We expect to open them for testing before September 10. All test users can obtain test tokens through the official faucet,which is for this test only.

    6. The current open version of the storage node is 512M, requiring 0.048KAK to be pledged. The minimum requirement for each validator node is 1000KAK.

    7. The startup of KAKLAB mainnet is still under consideration. The startup method will determine the validity of the pledged tokens and packaged data after the mainnet is officially launched. We will decide how to perform the early replacement of KAK tokens, and then notify early investors.
