    Quick look into DECENT

    The new way of publishing

    Our intention is to revolutionize digital distribution across the Internet.

    DECENT Network is a content distribution platform that is decentralized, open-source and uses Blockchain technology. Blockchain technology guarantees trust and security by embedding encryption at the lowest level. Perhaps the greatest benefit of this implementation of blockchain technology is invariant storage for published content which can eliminate manipulation and influence by any sort of middleman (eg. publisher). In short content can now be created and delivered directly with any fees collected solely by the seller at the point of sale. In addition to the technological side, there are the economical and social protocols that will govern real-world interactions across the network. In order to make transactions viable and user friendly a crypto-token, the DCT, has been implemented. The encrypted DCT tokens help mitigate attacks, promote funding and ensure transaction validation. One last thing of note, unlike other content distribution platforms underdevelopment, there are virtually no limitations as to the type of media that can be published on DECENT Network. It could be songs, books, articles, videos, source code, or anything really and in almost any format.


    Javascript library to work with Decent blockchain network.

    Quick start


    1. Install Node.js >6 and npm >3 globally

    2. Change directory to project root dir

    3. Install npm install decent-js

    4. Install decentjs-lib dependency library using npm install git+ssh://

    Initialize library

        import * as DecentjsLib from 'decentjs-lib';
        import * as decent from 'decent-js';
        const config = {
            decent_network_wspaths: ['wss://your.decent.daemon:8090'],
            chain_id: 'your-decent-chain-id'
        decent.initialize(config, DecentjsLib);

    Replace decent_network_wspaths with active decent daemon instance and chain_id with blockchain id which you are about to work on.


    Once Decent lib is initialized, you can access methods using Decent.instance().core

    Search content

        import * as decent from 'decent-js';
        const term = 'some phrase';
        const order = decent.SearchParamsOrder.createdDesc;
        const user = '1.2.345';
        const region_code = 'en';
        const itemId = '0.0.0';
        const category = '1';
        const count = 4;
        const searchParams: decent.SearchParams = new decent.SearchParams(
            term, order, user, region_code, itemId, category, count
            .then((contents: decent.Content[]) => {
                // process found content
            .catch(err => {
                // handle error

    Replace all variables with your values to get requested content. Search example

    Buy content

        import * as decent from 'decent-js';
        const contentId = '1.2.3';
        const accountId = '1.3.45';
        const privateKey = 'ac7b6876b8a7b68a7c6b8a7c6b8a7cb68a7cb78a6cb8';
        const elGammalPublic = '704978309485720398475187405981709436818374592763459872645';
            .then(() => {
                // Content successfully bought
            .catch(() => {
                // buy unsuccessful, handle buy error

    Replace variables with keys from your decent account to buy content. Otherwise you will not be able to buy content. Private key must be in WIF(Wallet Import Format). Buy example

    Download/Restore content

    Method restoreContentKeys will restore your key generated during content submission, used to encrypt content.

        import * as decent from 'decent-js';
        const elGamalPrivate = '32983749287349872934792739472387492387492834';
        const elGamalPublic = '704978309485720398475187405981709436818374592763459872645';
        const elGamalKeyPair = new decent.KeyPair(elGamalPrivate, elGamalPublic);
        const contentId = '1.2.312';
        // Content key restoration
        decent.content().restoreContentKeys(contentId, elGamalKeyPair)
            .then(key => {
                // ... now you are able to decrypt your content
            .catch(err => {
                // error restoring key
