Hivemind — openhive-network

Hivemind is a HAF-based microservice that indexes social data from the Hive blockchain and serves it to applications through SQL functions exposed by PostgREST.

Understand the project

Practical overview

When it fits

Use Hivemind when a Hive application needs indexed social data and an API layer that offloads most API requests from hived.

Who it is for

  • Developers building social-network applications on Hive.
  • Operators providing an API data layer for Hive social applications.

Documented uses

  • Serve discussion feeds, including blog, trending, hot and newly created views.
  • Retrieve community feeds, membership and moderation data.
  • Access normalized account profile and reputation data.
  • Read follow and reblog relationships and related social states.
Before you choose

Requirements & limits

The repository is public and identifies the project as open source under the MIT license.

  • A working HAF database is required.
  • The documented host setup uses PostgREST 12.0.2; Nginx rewrites JSON-RPC requests to its endpoint.
  • Reputation-dependent API calls require the separate reputation-tracker HAF application.
  • Hivemind processes irreversible blocks, and social-data queries may be slow before synchronization reaches the Hive head and creates indexes.
  • Wallet, order, escrow, key, recovery and account-history operations should be queried from hived.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Hivemind locally with a virtual environment

Install the Hivemind Python package on a host with an existing, working HAF database.

Before you start

  • An existing, working HAF database.
  • Python 3 and pip.
  • PostgREST version 12.0.2 installed for the Hivemind server.

Steps

  1. Clone the repository with its submodules: the command below, then enter the hivemind directory.

    Documented command
    git clone --recurse-submodules https://gitlab.syncad.com/hive/hivemind.git

  2. Update the Python installation tools with the command below.

    Documented command
    python3 -m pip install --upgrade pip setuptools wheel

  3. Create and activate a virtual environment, then install Hivemind: the command below, . venv/bin/activate, and the command below.

    Documented command
    python3 -m venv venv/
    Documented command
    pip install .

  4. Install PostgREST 12.0.2 using the README's download and installation steps, then verify it with postgrest --version.

Expected outcome

The Hivemind Python package is installed in a virtual environment, and the required PostgREST version is installed and verifiable.

Guide limitations

  • This installs the package but does not install or configure the HAF database or start the indexer or API server.
  • Hivemind processes irreversible blocks stored in the HAF database.
  • Nginx is required as a reverse proxy for the JSON-RPC API; its runtime configuration is not covered by this installation recipe.

Install Hivemind and reputation tracker into a local HAF database

Set up Hivemind and reputation tracker using the documented default local HAF database configuration.

Before you start

  • A locally installed HAF using the default configuration, such as PostgreSQL running on localhost.
  • The repository cloned with its submodules, including the Hivemind and reputation tracker scripts.

Steps

  1. Set up the PostgreSQL configuration with ./scripts/setup_postgres.sh --postgres-url=postgresql://haf_admin@localhost:5432/haf_block_log.

  2. Install reputation tracker with ./reputation_tracker/scripts/install_app.sh --postgres-url=postgresql://haf_admin@localhost:5432/haf_block_log --schema=reptracker_app --is_forking="false".

  3. Install Hivemind with ./scripts/install_app.sh --postgres-url=postgresql://haf_admin@localhost:5432/haf_block_log.

Expected outcome

The documented setup scripts have installed the PostgreSQL configuration, reputation tracker, and Hivemind application for the local HAF database.

Guide limitations

  • These steps cover installation only; they do not start synchronization or serve API requests.
  • The commands are documented for a local HAF installation using its default configuration.
