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.xyzThe 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.
