Hive - Decentralizing the exchange of ideas and information

Hive is a Graphene-based social blockchain that was created as a fork of Steem and born on the core idea of decentralization. Originally, Hive was announced on the Steem blockchain prior to the initial token airdrop. Hive did not have any ICO or mining period.

The Hive blockchain removes the elements of centralization and imbalanced control that plagued the Steem blockchain. Since it’s launch on March 20, 2020, Hive is growing and evolving day by day. Hive's prime selling points are its decentralization, 3 second transaction speed and ability to handle large volumes. It is ideal real estate for a variety of innovative projects focused on a broad range of fields, from open source development to games.

Hive serves as the operational home for all kinds of projects, companies, and applications. Having a highly active and passionate community, Hive has become a thriving atmosphere for new and experienced developers to quickly bootstrap their applications. On top of this, Hive is extremely rewarding to content creators and curators alike.

The technical development of the Hive blockchain itself is carried out by the founding decentralized group of over 30 open source developers, many of whom were instrumental in creating Steem back in 2016, and supported by a growing community of additional open source developers and witnesses.

Installation

Getting started with Hive is fairly simple. You can either choose to use pre-built docker-images, build with docker manually, or build from source directly. All steps have been documented and while many different OS are supported, the easiest one is Ubuntu 22.04 LTS.

Quickstart

Just want to get up and running quickly? We have pre-built Docker images for your convenience. More details are in our Quickstart Guide.

Building

We strongly recommend using one of the pre-built Docker images or using docker to build Hive. Both of these processes are described in the Quickstart Guide.

But if you would still like to build from source, we also have build instructions for Linux (Ubuntu LTS).

Dockerized deployment

Building a hived docker image is described here: Building under Docker

If you'd like to use our already pre-built official binary images, it's as simple as downloading it from the Dockerhub registry with only one command:

docker pull hiveio/hive

A script is available that wraps a docker run statement and emulates direct hived usage: run_hived_img.sh. This script is the recommended way to launch the hived docker container:

General usage: run_hived_img.sh <docker_img> [OPTION[=VALUE]]... [<hived_option>]...

Read more about using run_hived_img.sh in various scenarios.

CLI Wallet

We provide a basic cli wallet for interfacing with hived. The wallet is self-documented via command line help. The node you connect to via the cli wallet needs to be running the account_by_key_api, condenser_api, database_api, account_history_api, wallet_bridge_api plugins and needs to be configured to accept WebSocket connections via webserver-ws-endpoint.

The cli_wallet offers two operating modes:

• interactive mode: commands are entered on an interactive command line
• daemon mode: wallet commands are sent via RPC calls. In daemon mode it is important to specify which IP addresses are allowed to establish connections to the wallet's HTTP server. See --rpc-http-endpoint, --daemon, --rpc-http-allowip options for details.

To prepare transactions, you need to execute a few setup steps in the cli_wallet:

• use set_password call to establish a password protecting your wallet from unauthorized access
• use unlock to turn on full-operation mode in the wallet
• import private key(s) using import_key "WIF-key" command

Keys and password are stored in the wallet.json file.

Testing

See doc/devs/testing.md for testing build targets and info on how to use lcov to check code coverage of tests.

Configuration

Config File

Run hived once to generate a data directory and a config file. The default data directory location is ~/.hived. Kill hived. If you want to modify the config to your liking, we have example config used in the docker image. All options will be present in the default config file and there may be more options that need to be changed from the docker configs (some of the options actually used in images are configured via command line).

Seed Nodes

A list of some seed nodes to get you started can be found in doc/seednodes.txt.

This same file is baked into the docker images and can be overridden by setting HIVED_SEED_NODES in the container environment at docker run time to a whitespace-delimited list of seed nodes (with port).

System Requirements

Running a Hive consensus node requires the following hardware resources:

• data directory to hold a blockchain file(s) (~550GB of disk storage is required)
• storage to hold a shared memory file (~30GB of memory is required at the moment to store state data)
