VOTE FOR RUB ON NESTEX

A working network, ready for participation

Ruble Core is an independent SHA-256d proof-of-work blockchain. RUB is the native coin of its own network, with its own blocks, transactions, wallets and monetary policy.

Development has progressed from the initial network specification and wallet releases to a public mainnet, native ASIC mining and an operating Bitcoin AuxPoW merged-mining service.

You can participate today:

• Mine: connect compatible SHA-256 ASIC hardware to native RUB mining or the merged-mining endpoint below.
• Use RUB: receive and send transactions with the official desktop or web wallet.
• Verify: inspect blocks and transactions in the explorer, and monitor accepted work and accounting on the pool.
• Integrate: independent pools, node operators and service developers are welcome to discuss support for Ruble.

Bitcoin merged mining is active

AuxPoW activated at Ruble mainnet height 7,000. The official merged-mining endpoint is operating alongside native SHA-256d mining.

Ruble and Bitcoin blocks are found independently. A mining candidate can meet Ruble's difficulty without meeting Bitcoin's difficulty. RUB block production does not wait for a Bitcoin block. A BTC reward arises only when a valid Bitcoin block is found and accepted; BTC confirmations and the pool's payout rules then apply separately.

The merged-mining service supports ASICBoost/version rolling and automatic share-difficulty adjustment for compatible miners. Accepted work, balances and payout information are available through the pool dashboard.

Connect to merged mining

Code:

Server:   stratum+tcp://merge.rublecore.org:3340
Username: YOUR_RUB_ADDRESS.worker
Password: btc=YOUR_BTC_ADDRESS

Replace both address placeholders with receiving addresses you control. The worker suffix identifies your rig. The password field carries your BTC receiving address; it is not your wallet password.

Open the pool for current fees, payout thresholds and miner statistics

100,000 RUB reward for the first Bitcoin block

The pool owner has announced a personal 100,000 RUB reward for the miner who finds the first Bitcoin block on the Ruble Core pool through its merged-mining endpoint.

Mining endpoint: merge.rublecore.org:3340
Deadline: None.

Announcement on the official Ruble Core X profile — 5 September 2026

Native RUB mining remains available

Choose the endpoint that matches your setup:

Code:

General PPLNS:    stratum+tcp://pool.rublecore.org:3333
MiningRigRentals: stratum+tcp://pool.rublecore.org:3334
Solo:            stratum+tcp://pool.rublecore.org:3335

Username: YOUR_RUB_ADDRESS.worker
Password: x

Ports 3333 and 3334 provide native RUB PPLNS mining. Port 3335 provides native Solo mining. Bitcoin merged mining uses the separate endpoint on port 3340.

For connection help, post your miner model, firmware, selected endpoint and the error message in this thread or the official Telegram group. Remove any private credentials before sharing a screenshot or log.

Network and monetary policy

Coin	Ruble (RUB)
Consensus	Proof of Work: native SHA-256d and Bitcoin AuxPoW
Network block target	Approximately 180 seconds; a probabilistic average
Initial ordinary subsidy	100 RUB per block
Halving interval	500,000 blocks
Coinbase maturity	100 blocks
Difficulty adjustment	Per-block ASERT; 2-hour half-life
Precision	8 decimal places
Address formats	rub1… and supported legacy R… addresses

Transaction fees are separate from the block subsidy. Pool accounting distributes mining rewards; it does not create additional coins.

Need peer to sync core wallet please

Need peer to sync core wallet please

addnode pool.rublecore.org add in console. All synced now

[idev]

Solo Pool seems to be offline.

[WildBill32]

hello. Now, work will be carried out to improve the pool’s operation and add new mining modes. Various short‑term interruptions may occur. But everything should already be working properly in solo mode.I also recommend joining Telegram, for important events, news gets there first. @RubleCore

If someone's wallet isn't syncing, I recommend turning on a VPN first.

We are currently working on integrating the AuxPoW mechanism into the pool.
Therefore, short-term service outages are possible. We ask for your understanding.

RUBLE CORE WALLET UPDATE — v1.0.0rc7

Important update for existing Ruble Core users

A new Ruble Core wallet version is now available.

All users, miners and node operators are strongly recommended to update to Ruble Core v1.0.0rc7 before the upcoming network upgrade planned to begin on August 20, 2026.

The upgrade path from the previous public Ruble Core wallet has been tested successfully.

An existing encrypted wallet with an existing balance was opened by the new version successfully. The balance, wallet encryption and existing wallet data were preserved. A new address was created and a transaction was successfully created and confirmed after the upgrade.


HOW TO UPDATE — WINDOWS

1. Make a backup of your wallet.

2. Close the old Ruble Core using:

File → Exit

3. Wait approximately 10–20 seconds for Ruble Core to shut down completely.

4. Download the new official wallet:


Ruble Core v1.0.0rc7 — Official Download


5. Windows users can download:

ruble-core-v1.0.0rc7-win64-setup.exe

6. Run the installer normally.

You do NOT need to delete the old wallet before installation.

7. Start Ruble Core after installation.

Your existing wallet, addresses and balance should open automatically.

Verify that your balance is correct and allow the blockchain to synchronize normally.


IMPORTANT

DO NOT delete wallet.dat.

DO NOT delete your Ruble Core data directory.

DO NOT create a new wallet just because you are updating the software.

DO NOT move your RUB to another address for this update.

[WildBill32]

Dear community, here is an announcement regarding the upcoming update. Starting at block 7,000, merge mining will be launched. It will operate on a random basis—meaning it will not depend on Bitcoin; instead, Bitcoin will serve as an additional bonus reward. Blocks will be solved in any sequence: since Bitcoin has high difficulty and requires significantly more time to solve, Ruble blocks will be generated regardless of whether a Bitcoin block is found. In other words, you will get Ruble blocks (Ruble-Ruble-Ruble), with Bitcoin blocks acting as a bonus.

[WildBill32]

https://github.com/WildBill32/ruble-core-releases/releases/tag/v1.0.1

Update your wallets before starting merge mining. After block 7000, old wallets will stop synchronizing.

Ruble Core development update — 6 September 2026
Bitcoin merged mining is live. Native RUB mining continues.

Since this announcement thread opened, Ruble has moved through wallet releases, mining-service improvements and the activation of Bitcoin AuxPoW at mainnet height 7,000. The official merged-mining service is now operating, and the next stage is wider participation and Ruble's first exchange listing through the active NestEx vote.

What is available today

• A working Ruble mainnet with its own blocks, transactions and monetary policy.
• Native SHA-256d mining through PPLNS, MiningRigRentals and Solo endpoints.
• An active Bitcoin merged-mining endpoint, with ASICBoost/version-rolling support and automatic share difficulty.
• Official desktop and web wallets, a public explorer, and miner statistics and accounting.

What development has focused on

Early work established the Ruble network parameters, emission schedule and wallet packages. After mainnet launch, development focused on practical use: native mining, PPLNS accounting, wallet transactions and public access to blockchain data.

The August releases brought the v1.0.1 mainnet wallet and a v1.0.2 Windows maintenance update addressing an intermittent startup issue. The merged-mining rollout then focused on compatible ASIC work submission, version rolling, job updates and automatic difficulty. Recent work has concentrated on accounting performance, miner statistics, monitoring and the public interfaces.

Join merged mining

Code:

Server:   stratum+tcp://merge.rublecore.org:3340
Username: YOUR_RUB_ADDRESS.worker
Password: btc=YOUR_BTC_ADDRESS

Use your own RUB and BTC receiving addresses. RUB blocks do not depend on finding a BTC block. Each chain has its own difficulty and acceptance requirements. BTC rewards depend on a valid Bitcoin block being found and accepted, followed by the applicable confirmation and payout rules.

Hi, I just joined the forum. I wanted to let you know that I'm optimistic about this project. Just a suggestion, it would be great if the interface looked different; copy the design of the mempool for the mined blocks.
RUB FOREVER

[NEMORUB]

Bitcoin Core provides its full source code publicly and supports reproducible builds, allowing independent developers to compile a release and verify that the resulting binaries correspond to the published source.
Is Ruble Core planning to provide the same level of verification?
Specifically, will the complete source code be made public with version tags corresponding to official releases, so that anyone can independently build Ruble Core and verify the distributed binaries?
At the moment, publishing SHA256 checksums verifies the integrity of the downloaded binary, but it does not allow users to verify which source code produced that binary.
I think providing full buildable source code would significantly improve trust and technical credibility around Ruble Core.

[WildBill32]

At present, this information is confidential and unavailable to ordinary users! It will be provided only to mining pools and exchanges. I will publish this information once the blockchain development goals have been met and integration with major pools and exchanges is complete.


There could be exceptions once a large base of miners is reached, since no such base exists at the moment and there is no reason to provide the information.


Information may also be provided to investors.Friends, for those currently engaged in mining, I recommend using "merge mining" mode. The blockchain architecture is designed so that Ruble blocks are mined independently of Bitcoin blocks; by using this mode, you will mine the same amount of Ruble while also gaining the chance to mine a Bitcoin block! You don't have to wait for a Bitcoin block to appear in order to mine Ruble! It works the other way around here: Bitcoin comes as a bonus to Ruble—provided, of course, that luck is on your side!

[WildBill32]

🔎 Ruble Core Explorer has been updated!

no source code, auxiliar merged mining removed from binaries, no one can create a pool for it

That was done intentionally! Which pool do you represent? You can contact me directly via the Telegram group, and we can discuss everything.

[soulistyce]

ived contact to mine aux in my home solo asicboost yiimp pool and the reply was, conversations under way with major pools, if you want mine on my pool....
THATS CENTRALISING HASHRATE, so if i want to merged mine i need to mine bitcoin on your pool so you can get a lot on fees of bitcoin if i win a block...
SCAM as it can get...
like i said, hidden source code, merged removed so nobody can do it....i bet no great pool wants your coin, and without the source code youll never going to be listed on Miner Streams Stats

[WildBill32]

You can't even string two words together. What do you actually want? Are you some kind of labor rights crusader? Go solo-mine BTC on your own home pool at 20 TH/s and find a block, and stop spouting nonsense to me about fraud. Anyone who needed to connect their pools has already done so long ago.

"Centralized hashrate"—you’re making me laugh. Anyone can go to the explorer and see who’s mining the blocks; I use a good explorer, and everything is visible there. I’ll say it again: I don’t deal with crazy people who’ve concocted some idea that they’re owed something and go hopping around like fleas.

[HashCaliber]

Your GitHub is super light on code. Even your GUI wallet is just hosted the exe file without any actual code there. I would feel much better if I could something, some sort of transparency into this project.

Hi
I got the rubel coin synced on V1 source code, but its now stuck here... "chain": "main",
  "blocks": 5999,
  "headers": 7227,
 


So we cant sync it passed that. I am trying to set it up as auxpow but cannot find an update after this, is the new source code available to allow us to get passed this point ?
Regards

Andy

he remove auxpow from code so no one can merged it unless he wants too, and he is not posting the source code because of that just binaries
