Berryminer is an open-source mining program for people who want to take part in the Berry oracle network by solving proof-of-work challenges that feed price data to the blockchain. It is aimed at technically comfortable users who are willing to run a command-line tool and understand the economics of staking a deposit.
The software is a fork of the Tellor miner, adapted for Berry oracle price feeding. Within the Miner system it does the heavy lifting: it takes on solving the proof-of-work challenge that a reporter must complete before submitting a value. Note that the project has had no code updates since May 2021, so treat it as a legacy tool and review its state before committing any funds.
What Is Berryminer and Why Does It Exist?
Berryminer exists to support the Berry oracle network. Oracles are services that bring off-chain information, such as asset prices, onto a blockchain where smart contracts can read it. Someone has to supply that data, and the network needs a way to make supplying it costly enough that people do not submit fake numbers.
Berryminer addresses that second need. It handles the computational work of the proof-of-work challenge, so a reporter can prove effort before a value is accepted. It is a tool for operators, not a casual app for holding or trading assets.
Who Is Berryminer For?
The program suits developers, infrastructure hobbyists and people already familiar with blockchain nodes and command-line tools. Because it is open source, it also appeals to readers who want to inspect how oracle reporting works in code before running anything.
It is a poor fit for someone looking for a point-and-click tool, a passive income button or a product with active support. Given the lack of updates since 2021, many users will find it more valuable as a learning resource and reference implementation than as a daily production tool.
How Oracle Reporting Works in Practice
In a typical flow, a reporter fetches a price from one or more sources, prepares the value, and runs the proof-of-work step before submitting it. The miner's role is that computational step. The network then aggregates reports, and the security deposit discourages anyone from reporting values that deviate from the consensus.
The design rewards careful, honest operators and penalizes bad actors. Understanding that trade-off is more important than any single setting in the software.
Key Terms Explained for Newcomers
A few concepts come up repeatedly. A security deposit is tokens locked as collateral; slashing means that collateral can be taken if the network judges a submission to be dishonest. A proof-of-work challenge requires computation that is cheap to verify but expensive to produce.
A decentralized oracle is a data feed run by many independent participants rather than one company. Knowing these terms makes the rest of the documentation much easier to follow.

How to install Berryminer on Windows
- 1
Confirm the Source
Open the official project page on GitHub at https://github.com/berrydata/berryminer and check the Releases section. Download only from the official website or the GitHub Releases page; avoid mirrors and file-sharing sites.
- 2
Verify the File
Compare the SHA-256 checksum of the downloaded file with the value published by the project. If the release includes a signature, verify that as well before running the program.
- 3
Install or Extract
Run the Windows build or installer if one is provided for the release you chose, or extract the archive to a folder you control. Keep the program in a location where you can easily find its configuration files.
-
Prepare Your Environment
Make sure you have the Berry Tributes needed for the security deposit before configuring the miner. Review the configuration options in the documentation so you understand what each setting does before starting.
How to use Berryminer
Using Berryminer is a command-line workflow. The steps below outline the general process; check the project documentation for the exact commands and options in the release you installed.
- Open a Command Prompt or PowerShell window in the folder where the program is located.
- Review the configuration file or the documented options so you know which network and account settings apply.
- Make sure your account holds the 1000 Berry Tributes required as a security deposit.
- Start the miner with the documented command and watch the output for connection and challenge messages.
- Monitor the log for errors, especially repeated failed submissions, which may indicate a configuration or network problem.
- Stop the program cleanly when you are finished so no partial submissions are left in an unknown state.
Pros & cons
- Open source, so the code can be inspected line by line
- Based on a known oracle-reporting design derived from the Tellor miner
- Written in Go, which typically yields a single compiled program
- Clear economic accountability through the security deposit and slashing mechanism
- Free to download and use
- No code updates since May 2021, so compatibility with current networks is uncertain
- Requires a 1000 Berry Tributes deposit, which puts real value at risk
- Command-line only, which is a barrier for non-technical users
- Limited documentation and community support compared with mainstream miners
- Official platform listings mention macOS and Linux, so Windows use may be less tested
Is Berryminer safe?
Berryminer is open source, which helps, but its project status matters. With no code updates since 2021, do not assume it works correctly with current infrastructure. Download only from the official website or GitHub Releases, and verify the SHA-256 checksum or signature before running any file. Never enter a seed phrase or private key on third-party websites, and do not share wallet credentials with anyone offering help.
Because the program handles a security deposit, a mistake can cost tokens. Antivirus software sometimes flags miners as suspicious. If that happens, investigate the detection and verify the file's checksum rather than disabling your protection entirely. Only run software you have verified from its source.
- Official source only. Download from github.com/berrydata/berryminer. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Berryminer sits in a narrow niche: it is an oracle-reporting miner, not a general-purpose GPU or CPU miner. The similar programs in this catalog mostly target conventional coin mining, so the goal and the economics are different. T-Rex Miner, BzMiner and Cpuminer GR, for example, are built to hash for rewards on specific algorithms rather than to submit price data.
The closest relative is Berryminerv1, which is also a Tellor-derived oracle miner but based on an earlier telliot 3.0.3 fork. Choosing between the two depends on which Berry release and network version you need, so check the documentation of each before deciding.

Frequently asked questions
Yes, Berryminer is listed as free and open source. However, running it requires a security deposit of 1000 Berry Tributes, which is a separate cost you need to consider. The software itself carries no listed price.
It is safe only if you get it from the official project page or GitHub Releases and verify the SHA-256 checksum or signature. Because there have been no code updates since 2021, review the state of the project before using it with real tokens.
Berryminer solves the proof-of-work challenge required to submit price data to the Berry oracle network. It is a fork of the Tellor miner and serves as the computational component of the reporting system.
The 1000 tokens act as a security deposit. If a reporter submits a bad value, the community can vote to slash that deposit, which discourages dishonest reporting and keeps the oracle data reliable.
The documentation mentions Bitcoin (BTC), Ethereum (ETH) and BNB Chain in connection with the Berry price feeds. Check the current documentation to confirm which networks a given release supports.
The program is listed with Windows support through a Windows build or installer. Official platform references also mention macOS and Linux, so Windows use may be less tested, and you should check the release notes carefully.
No. Berryminer is forked from the telliot 4.02 Tellor miner, while Berryminerv1 is forked from telliot 3.0.3. They share a purpose but are separate programs, so confirm which version matches your network.
Any reward depends on network conditions, the value of tokens and your own costs, and nothing is guaranteed. Treat the software as a technical tool, and never risk more than you can afford to lose.
Verdict
Berryminer is a niche, open-source tool for technically skilled operators who want to take part in Berry oracle price feeding. Its code is inspectable and its design is clear, but the lack of updates since 2021 and the requirement to stake 1000 Berry Tributes make it a cautious choice. Verify every download, understand the deposit risk, and review the project's current state before you commit.
