[TESTING] BitcoinBT — Bitcoin Hard Fork(Core v26) | SHA256 Mining Open

[BitcoinBT]

BitcoinBT — Public Testing Phase (Bitcoin Core v26 Hard Fork)

Hello Bitcoin community,

We are opening public external testing for BitcoinBT (BTCBT).

This post is NOT an ANN, NOT an investment offer, and NOT a token sale.
The purpose of this phase is strictly technical validation through independent testers.

---

What is BitcoinBT?

BitcoinBT is a Bitcoin hard fork built on Bitcoin Core v26.

Key parameters:

• Fork point: Bitcoin block 903,844
• Activation block: 903,845
• Mining algorithm: SHA-256
• Block interval: 5 minutes
• Difficulty adjustment: ASERT
• Maximum block size: 32 MB (adaptive)
• Script features: SegWit, Taproot, Schnorr

BitcoinBT inherits the Bitcoin blockchain history up to the fork point and applies new consensus rules afterward.

There is no premine, no ICO, and no airdrop.
Coins are created only through mining.

---

Chain Model

BitcoinBT follows a Bitcoin hard fork model.

The chain inherits the Bitcoin blockchain history up to block 903,844.
New consensus rules activate starting from block 903,845.

The original Bitcoin genesis block is preserved, and the network continues from the inherited chain state with modified consensus parameters.

The goal is to maintain compatibility with the Bitcoin architecture while experimenting with different block timing and scaling parameters.

---

Current Status

The network is currently running in a public testing phase.

Internal testing has confirmed:

• Multi-node synchronization
• Clean OS installation tests
• Block generation and validation
• Wallet creation and transactions
• Mining operation
• Block explorer operation

External testing is now needed to validate behavior across different environments.

---

Network Status

You can view the current network activity here:

https://explorer.bitcoinbt.xyz

The explorer shows blocks, transactions, and mining activity in real time.

---

Quick Start (Testing in a Few Minutes)

1. Download the BitcoinBT wallet
2. Run the node
3. Wait for synchronization
4. Create a wallet
5. Send a test transaction or connect a miner

Testing can usually begin within a few minutes after synchronization starts.

---

Testing Participation

Anyone interested can participate by:

• Running a node
• Creating a wallet
• Sending and receiving test transactions
• Connecting miners
• Reporting unexpected behavior

Bug reports including logs and reproduction steps are highly appreciated.

---

Mining

Miners can connect to the BitcoinBT pool using:

Code:

stratum+tcp://pool.bitcoinbt.xyz:3333

Algorithm: SHA-256

Independent nodes and smaller miners help strengthen the early network.

SHA256 miners interested in testing new networks are welcome to participate.

---

Synchronization Troubleshooting (Windows)

If the wallet remains at block height 0 or synchronization does not begin:

1. Open Help → Debug Window
2. Select the Console tab
3. Run the command:

Code:

addnode "bitcoinbt.xyz:8333" "add"

This connects your node to a known BitcoinBT peer and helps initiate blockchain synchronization.

Allow a few minutes for block download to begin.

Important Notes

BitcoinBT is not Bitcoin and does not claim to replace Bitcoin.

BTC holders do not automatically receive BitcoinBT.

This phase is testing only, and parameters may still change based on testing feedback.

No price discussion, trading, or exchange topics at this stage.

---

Early Participation

Participants in the testing phase may become some of the first miners when the BitcoinBT mainnet launches.

Running nodes, testing transactions, and identifying issues contributes directly to the stability of the future network.

Active testers may be acknowledged in future project documentation.

---

Community Feedback

If you run a node, please share your experience and logs.
Even small feedback helps improve the network.

---

Technical feedback and constructive criticism are welcome.

Testing environments currently include:

• Windows nodes
• Linux nodes
• multi-node synchronization tests
• mining pool integration

The BitcoinBT network is currently producing blocks and running normally during the public testing phase.

External testers are welcome to help validate the network across different environments.

You can participate by:

• running a node
• testing wallet transactions
• connecting a SHA256 miner
• reporting unexpected behavior

Mining pool:

stratum+tcp://pool.bitcoinbt.xyz:3333I have set up this mining pool address, but it has no effect at all. I can't see anything. The website shows "too many requests" as soon as I refresh it. My miners are unable to connect, and I've tried many times but still can't fix the problem. Could you please test it yourselves? I also can't see the connected miners on the website.

[BitcoinBtTeam]

@guogai,

Thanks for reporting.

The mining pool itself is working normally.
We have tested the pool again and confirmed that Stratum connections are active and blocks are being mined successfully.

If the website shows "too many requests", that is only a temporary API rate limit on the explorer or stats endpoint and does not affect mining.

Stratum server:
stratum+tcp://pool.bitcoinbt.xyz:3333

The server is fully operational.

If you still cannot connect, please post your miner log so we can help troubleshoot.

If possible, please also confirm the following:

1. Your miner software (cgminer / cpuminer / ASIC)
2. Your miner configuration
3. Whether port 3333 is reachable from your network

This information will help us diagnose the issue more accurately.

You may also contact us directly at:

[info@bitcoinbt.xyz](mailto:info@bitcoinbt.xyz)

Thank you for participating in the BitcoinBT testing phase.
We greatly appreciate your support and will do our best to resolve any issues as quickly as possible.

I am using an Avalon 3s mining machine, and the mining pool I have connected to is working properly, but I don't seem to be participating in the mining process. My address is bcbt1qvtatvwvwettsskgh7mhvv4jf6y850k59uaw8y. Could you help me check it? I often can't access that website and can't see anything. Moreover, so far, no one except you seems to have successfully connected to the mining pool.

[BitcoinBtTeam]

@guogai,

Thanks for reporting.

We confirmed that your miner is able to connect to the stratum server, but your shares do not appear to be submitting consistently. This is likely related to the current difficulty setting on the ASIC port during the testing phase.

We are adjusting the pool difficulty parameters now to improve participation for miners such as Avalon 3S.

Please reconnect again after a short while using:

stratum+tcp://pool.bitcoinbt.xyz:3333

Address:
bcbt1qvtatvwvwettsksgh7mhmvv4jf6y850k59uaw8y

The website and explorer may sometimes be temporarily unavailable, but that does not always affect mining itself.

Thank you for your test and for reporting the issue.

[guogai]

It doesn't seem to have worked. I'm sorry, but I'm not a developer and I can't find where the logs are. However, the miner automatically switches to my second configured mining pool, which proves that I can't connect to this mining pool properly. The problem still doesn't seem to be fixed. I don't know what to do, and I still can't mine coins right now.

[BitcoinBtTeam]

Hello,@guogai

Thank you for the update.

If your miner automatically switches to the second pool, it usually means the server is reachable, but the miner is not completing a usable mining session on the first pool.

Please check the following carefully:

Please confirm that your worker address is a real BTCBT address created from the BitcoinBT QT wallet / BTCBT wallet.
A normal Bitcoin (BTC) address cannot be used for BTCBT pool mining payouts.

Please confirm again that this address:

bcbt1qvtatvwvwettsskgh7mhvv4jf6yf850k59uaw8y

was created from the BitcoinBT wallet, not from a normal Bitcoin wallet.

Please use these exact settings:

Pool 1
stratum+tcp://pool.bitcoinbt.xyz:3333

Worker
bcbt1qvtatvwvwettsskgh7mhvv4jf6yf850k59uaw8y

Password
x

If port 3333 does not work, please also test:

Pool 2
stratum+tcp://pool.bitcoinbt.xyz:3032

Use the same worker and password.

Please temporarily disable your backup / second pool and test only one BTCBT pool at a time for a few minutes.
Otherwise the miner may switch too quickly and hide the real problem.

Please reboot the miner after saving the settings, then wait 2–3 minutes and check whether it stays on our pool or switches away again.

Please send screenshots of:

pool configuration page

miner status page

any page showing messages such as: failed, dead, rejected, switch pool, authorization, stratum

You do not need developer knowledge. Screenshots are enough.

You can reply here or send the screenshots to:

info@bitcoinbt.xyz

Once we receive the screenshots, we will check it more precisely.

Thank you for testing BitcoinBT.
