    • Introduction

    Blocknet provides a simple and powerful API to build previously impossible multi-chain applications that consume services on different blockchains, all while remaining 100% trustless and decentralized.

    The API is accessible through command line (cli) with additional endpoints on the way. Code examples can be viewed in the dark panels next to each respective API call.

    Please see Getting Started to begin using the APIs or continue reading below to learn more about the Blocknet Protocol, the different components, and how they all work.

    Blocknet Protocol

    Blocknet is an interoperability protocol that can be used as a 2nd layer on any compatible blockchain to enable decentralized communication and exchange between different blockchains in a permissionless and trustless manner. Blockchain interoperability comes in 2 parts: exchange(XBridge) and communication(XRouter).

    The protocol is supported by a network of Service Nodes, which are similar to masternodes with an increased level of participation. Service Nodes host full nodes of the blockchains the protocol is compatible with, host microservices, verify interactions between peers, route communication between blockchains, participate in governance by voting, and perform anti-spam and anti-DOS measures for the network.

    BLOCK is the utility token of the Blocknet blockchain and powers the Blocknet Protocol. BLOCK is used to pay fees for the network's services, such as those provided by XBridge](#xbridge) and XRouter. Through these fees, BLOCK is also used for compensation to participating Service Nodes to incentivize support.

    XBridge

    XBridge provides the ability to perform atomic swap exchanges between any digital asset that is supported by the Blocknet Protocol via APIs (view list). When paired with XRouter, any application can perform exchanges between any compatible blockchains using SPV. The entire process is done in a trustless manner by decentralizing the storage of funds, order books, order matching, and asset exchange:

    [1] ACCT using Check Lock Time Verify (#4)

    The exchange takes place on each respective blockchain. Note that once an exchange is completed, when the funds are received will be dependent on the blockchain's accepted confirmation time. By default, the required amount of confirmations is set 0 and the funds aren't spent until each blockchain achieves their respective required amount of confirmations. For instance, lets look at an example of an exchange between BTC requireing 1 confirmation and BLOCK requiring 2 confirmations. BLOCK has a faster confirmation time so it will receive 2 confirmations while BTC has 0, but the funds will not be spent until BLOCK has at least 2 confirmation and BTC has at least 1 confirmation.

    There is currently a fixed fee of 0.015 BLOCK to take(fill) an order and no fee to make(create) an order.

    Design

    The following diagrams depict the events of an exchange with various outcomes. As seen in the diagrams, a "client" refers to software utlizing the Blocknet Protocol, which can be a blockchain, microservice, dApp, mobile app, website, etc.

    XRouter

    XRouter provides the Blocknet Protocol with a communication layer consisting of an inter-blockchain SPV client backend, enabling the verification of blockchain records without requiring users to download the full blockchain. This empowers development of lightweight microservice architectures that harness contracts, protocols, and services from other blockchains, laying a foundation for a decentralized API ecosystem.

    There is currently no fee to use XRouter, but the client needs to have at least 200 BLOCK on any account. This is used as a spam deterrent until the fee structure is implemented.

    Design

    The XRouter system utilizes the Service Node network to route calls from the client directly to the respective blockchain. There are 2 types of XRouter calls: submissions and queries.

    XRouter submissions are calls that involve interactions with a blockchain, such as xrSendTransaction. With submissions, the packets are routed from the client to the respective blockchain and a response, if any, is routed back to the client.

    XRouter queries are calls requesting information from a blockchain, such as xrGetBlockCount. With queries, the packets are also routed from the client to the respective blockchain and the response of the information queried is routed back to the client. XRouter queries can require a specific amount of Service Nodes to receive a response from in order to achieve consensus on the final answer.

    The following diagrams depict the events of an XRouter query and submission. As seen in the diagrams, a "client" refers to software utlizing the Blocknet Protocol, which can be a blockchain, microservice, dApp, mobile app, website, etc.

    XRouter Query (view full size image)

    The flow of the diagram is top-to-bottom:

    1. The client dispatches a packet for a query via API call to the Service Node network;
    2. The Service Nodes supporting the queried blockchain receive the packet;
    3. The Service Nodes route the packet of the query to the blockchain;
    4. The Service Nodes route the response from the blockchain back to the client;
    5. The client evaluates the responses for a majority consensus on the final answer;
    XRouter Submission (view full size image)
    1. The client dispatches a packet for a submission via API call to the Service Node network;
    2. The Service Nodes supporting the desired blockchain receive the packet;
    3. The Service Nodes route the packet of the query to the blockchain;
    4. IF there is a response from the blockchain, the Service Nodes route the response back to the client;

    Getting Started

    The Blocknet Protocol currently requires a synced Blocknet wallet, as well as the synced wallet of any blockchain that will be interacted with. In the future, with the use of XRouter, this will not be required. In addition, configuration files must also be composed.

    Wallet Setup

    Sample blocknetdx.conf

    listen=1
server=1
rpcallowip=127.0.0.1
rpcuser=user
rpcpassword=pass
port=41412
rpcport=41414
    1. Download and install the latest Blocknet wallet;
    2. Open the wallet, encrypt it, and sync the blockchain;
    3. Compose blocknetdx.conf as seen in the sample;
    4. Set an RPC username and password in blocknetdx.conf;
    5. If using the XBridge API, see XBridge Setup
    6. If using the XRouter API, see XRouter Setup

    XBridge Setup

    Sample xbridge.conf

    1. Compose xbridge.conf as seen in the sample;
      • Video tutorial;
      • This configuration file can be customized for whichever blockchains will be interacted with;
      • Here are configurations for other blockchains. Use the manifest to determine which files to use for which blockchain and wallet versions;
      • The entire code area in the link above can be added to xbridge.conf as having configurations for blockchains not used is okay;
      • The BLOCK configurations will always be required;
      • ExchangeWallets= under [Main] must also include each blockchain's symbol;
      • Confirmations= is the number of confirmations required before funds are redeemable from the atomic swap contract;
    2. Compose the wallet configuration file for whichever blockchains will be interacted with;
    3. If any of the wallets are still open, they must be restarted in order to activate the new configurations;
    4. Open, sync, and unlock the Blocknet wallet, as well as whichever blockchains will be interacted with;
    5. Using the command line(cli), XBridge API calls can now be made;
    6. If also using the XRouter API, see XRouter Setup;

    XRouter Setup

    Sample xrouter.conf

    [Main]
xrouter=1

    Sample blocknetdx.conf

    listen=1
server=1
rpcallowip=127.0.0.1
rpcuser=user
rpcpassword=pass
port=41412
rpcport=41414

    Please contact @hanniabu or @86b on Discord for a test build

    1. Compose xrouter.conf as seen in the sample;
      1. xrouter=1 enables XRouter and xrouter=0 disables XRouter;
    2. Peers that have XRouter enabled must be added to blocknetdx.conf;
      1. This is temporary and for development purposes only until auto peer finding is released;
    3. If any of the wallets are still open, they must be restarted in order to activate the new configurations;
    4. Open (or restart if already open), sync, and unlock the Blocknet wallet;
    5. At this time, the client needs to have at least 200 BLOCK on any account;
    6. Using the command line(cli), XRouter API calls can now be made;
    7. If also using the XBridge API, see XBridge Setup;
