ARC Core is a free, open-source full node and desktop wallet for the Advanced Technology Coin network, aimed at users who want to run their own copy of the blockchain instead of trusting a remote server. The program is written in C/C++ with a Qt graphical interface and is adapted from the Bitcoin and Litecoin codebase, so people familiar with those clients will find the layout familiar. Builds are available for Windows, macOS and Linux, and the software is released under the MIT license.
Before you install anything, note that the project's last code update was on February 26, 2022, and the most recent release is v0.13.0. Software that has not been updated for more than two years may not keep pace with network changes or newer operating systems, so treat it as a legacy tool and review its status before relying on it. The sections below explain what the program does, how to install it safely, and when it makes sense to use it.
What Is a Full Node and Why Run One?
A full node is a program that downloads the complete history of a blockchain, verifies every block and transaction against the network rules, and relays valid data to other peers. Unlike a lightweight wallet, which asks a remote server for balances, a full node draws its conclusions from its own checks. That independence is the main reason people run one.
The trade-off is resources. A node must stay online to remain current, store the chain data on disk, and use bandwidth to sync with peers. Initial synchronization can take a long time, and the chain data keeps growing. Before starting, make sure your drive has enough free space and that your computer can stay on for long stretches.
For many users, a node is less about earning anything and more about trust. When you run your own software, you do not have to rely on a company's servers to tell you what your balance is or whether a payment has confirmed. Keep in mind that running a node does not change the value of any coin, and it does not guarantee that your transactions will be accepted by others.
How Bitcoin-Derived Core Software Works
Many cryptocurrency projects start from Bitcoin's open-source code. They keep its basic architecture and change parameters such as block timing, network ports, address formats and supply rules. ARC Core follows this pattern, drawing on the Bitcoin and Litecoin codebase, so its general behavior will be recognizable to anyone who has used those clients.
A typical Core-style program has two parts: a background engine that handles networking and validation, and a user interface that sends commands to it. In a desktop build, both usually run inside one window, but the design makes it possible to run the engine alone on a server. Many such clients also read settings from a configuration file and expose a local remote-procedure interface for advanced users and scripts.
Forked code has a practical consequence. Bugs and security issues found in the parent code can sometimes affect descendants, and an older fork may lag behind upstream improvements. This is one reason to pay attention to the date of the most recent code update before trusting any fork with real funds.
Practical Use Cases for a Desktop Full Node
Some people run a node to check their own balances privately. Instead of entering an address into a third-party explorer, they query their own copy of the chain. This approach keeps the list of addresses they care about off external servers, which is a meaningful privacy gain for many holders.
Others use a node as a learning tool. Students and researchers can watch blocks arrive, inspect raw transactions and see how fees and confirmations behave on a real network. A desktop build is easier to explore than a server setup because everything is visible in one place.
Developers sometimes run a local node while testing a wallet integration, a payment script or an exchange-style deposit flow. Testing against your own node avoids relying on public infrastructure during experiments. Use test data and small amounts, and keep your main holdings in a separate, well-backed-up wallet until you are confident in your setup.
Key features
Full Node Operation
Built-In Wallet
Open-Source MIT Code
Desktop Builds for Three Systems
Supported coins
ARC Core is built for the Advanced Technology Coin network. Because the software is designed around that single network, it is best understood as a node and wallet for that coin rather than a general multi-asset tool. Check the project's repository before assuming support for any other chain.
How to install ARC Core on Windows
- 1
Get the Installer from the Official Source
Download only from the official website or the project's GitHub Releases page at github.com/advancedtechnologycoin/arc_core. Choose the Windows build or installer that matches the version you intend to run, and avoid mirrors or links shared in chat rooms and comment sections.
- 2
Verify the File Before Running It
Compute the SHA-256 checksum of the downloaded file using a built-in tool such as PowerShell's Get-FileHash command. Compare the result with the checksum published alongside the release. If the values do not match, delete the file and download it again from the official source. If a release has a signature, verify that as well.
-
Install and Allow Synchronization
Run the installer and follow the on-screen prompts, choosing a folder with plenty of free disk space. On first launch, let the program synchronize with the network. This can take a long time, and the program should stay open or run in the background until it finishes.
How to use ARC Core
Using ARC Core well starts with patience and a clear plan. The first launch is mostly about synchronization, and the wallet features are only as safe as the backups you make.
- Install the program and open it once so that it creates its data folder.
- Let the node synchronize fully before relying on balances or transaction history.
- Open the wallet section and create or restore a wallet, noting where its file is stored.
- Write down your recovery phrase or make a backup copy of the wallet file, and store it offline.
- Test with a small transfer before sending larger amounts.
- Check the status bar or sync indicator before reading balances, since an unfinished sync can show outdated numbers.
- Keep the computer online during synchronization and close the program properly so the data files are saved cleanly.
Pros & cons
- Free and released under the MIT license
- Open-source code that can be audited
- Runs your own full node instead of relying on a remote server
- Keeps wallet keys on your own computer
- Available for Windows, macOS and Linux
- Qt desktop interface that is easier to use than many command-line nodes
- The last code update was on February 26, 2022
- Supports a single niche network rather than many coins
- Full node synchronization takes time and disk space
- You are fully responsible for backups and key security
- Smaller community than the most widely used node projects
Is ARC Core safe?
Safety starts with where you get the file. Download only from the official website or the project's GitHub Releases page, and compare the SHA-256 checksum of the installer with the value published for that release. If there is a signature, verify it too. Never enter your seed phrase or wallet passphrase on third-party websites, in chat messages or in any form that asks you to reveal it.
The project's last code update was in February 2022, so this is a legacy release. Older software can carry unpatched issues, and the network may have changed since then. Keep the wallet on a machine you control, back it up offline, and check the latest version on the official website before you decide to rely on it. Start with small test transfers.
- Official source only. Download from github.com/advancedtechnologycoin/arc_core. 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
ARC Core sits in the same family as Dogecoin Core, Litecoin Core and Qtum Core. These programs are full nodes and wallets built around the Bitcoin-style design, so their menus and concepts overlap. The difference lies in the network each one serves. ARC Core is specific to Advanced Technology Coin, while the others connect to their own chains.
Monero CLI takes a different approach. It is a command-line daemon and wallet for Monero, with a different codebase and privacy model, so it suits users comfortable with a terminal. Komodo Core and DERO HE are also node-and-wallet programs for their own networks. If you want a graphical desktop client for a specific chain, compare the update history and community activity of each project before choosing.

Frequently asked questions
The last code update was on February 26, 2022, and the latest release is v0.13.0. That means the project has not been updated for more than two years. Review the repository and the official website before using it for real funds, and treat it as a legacy tool.
Yes, the software is free and released under the MIT license. You can download it, install it and use it without paying the developers. Costs you may still face include disk space, electricity and the time needed to synchronize the blockchain.
Yes. The source code is published on GitHub under the MIT license, which lets anyone read, audit, modify and reuse it. Open code makes review possible, but it does not guarantee the software is free of bugs, so check the release carefully.
A full node is software that stores the complete blockchain history and checks every block and transaction against the network rules. It does not rely on a third party to confirm balances. Running one takes disk space, bandwidth and an computer that stays online for long periods.
Yes, the program includes wallet functions for Advanced Technology Coin. Your keys are stored on your computer, so you must back them up and protect the wallet file. If the file is lost and you have no backup, the funds in it cannot be recovered by the software.
No, most people hold coins with a lighter wallet and never run a node. A full node is useful if you want to verify balances yourself, avoid relying on external servers or learn how the network works. Choose the approach that fits your technical comfort and available resources.
Verdict
ARC Core suits people who want an independent, free and open-source full node and wallet for the Advanced Technology Coin network, and who are comfortable with desktop software and manual backups. It is a reasonable choice for learners, privacy-minded holders and developers testing against a local node. It is less suitable for anyone who wants frequent updates or a large community, because the last code update came in February 2022. Before installing, verify the file and review the current status on the official website.
