Vision
The main goal of Bitcoin-Blu is the same as the goal of the original Bitcoin.


“Bitcoin-Blu (BBLU) enables individuals to transact securely and freely, without relying on banks or trusted intermediaries, through a decentralized, peer-to-peer digital cash system.” 



While Bitcoin (BTC) has become expensive to use, with very high mining difficulty and relatively low rewards for finding new blocks, Bitcoin-Blu (BBLU) offers a more accessible alternative. Its design could allow lower transaction costs, fairer mining opportunities, and greater participation across a wider community. Bitcoin-Blu could innovate, compete, and provide alternatives without altering BTC, but it would need time, adoption, and trust to become meaningful. It could also increase the overall robustness of decentralized money: if one chain suffers a major attack, users could switch to the other — a form of systemic redundancy.

If you would like to support the movement,
I would be happy if you could help with paying the server bills.

  ok, the network difficulty exploded!

the experimental pool has a problem with payout. I will try to fix it and try to payout manually.

Code:

[Bitcoin Payout Handler] sendmany returned error: The inputs size exceeds the maximum weight. Please try sending a smaller amount or manually consolidating your wallet's UTXOs code -6

I have to restart the database, I'm sorry.

Mac Os wallet or Android wallet plase

I'm sorry, there is no standalone wallet implementation until now.
To get a wallet, you have to install a bitcoin-blu (macOS, unix) full node.
Please see https://www.bitcoin-blu.com for details.

According to your GitHub post, even though the Linux wallet compiler installs without any problems, MiningCore doesn't like the wallet structure. If I code for this, other coins won't work. I'll re-evaluate when you make a new wallet change. (I hope so.)

You're right. You can not configure a new altcoin like Bitcoin-Blu (different address prefixes) out of the box with MiningCore (as far as I know). I had to alter the source code. First I had to extend the NBitcoin library with a file for Bitcoin-Blu. Then I had to alter MiningCore to load the new coin Bitcoin-Blu. And then I had to create a coins.json and config.json for MiningCore.

Looks okay but seems to have stopped at block height 30860.

Thanks for your feedback. I have created a cron job now.

When will the next difficulty adjustment occur?

When will the next difficulty adjustment occur?

The next difficulty adjustment will be on block 32256. The date is heavily dependent on the hash rate. With the current hashrate it is approximately in 2 and a half day.

UBUNTU2204 compilation error, can you provide the compiled installation package, UBUNTU or WINDOWS system installation package

  Thank you very much to compile the source!
The source is a clone of the original bitcoin source including small adjustments.
Did you follow the original instructions on GitHub (https://github.com/bitcoin-blu/bitcoin-blu)

Code:

bitcoin-blu/doc/build-unix.md

for building on unix e.g. ubuntu? (the windows version does not compile at the moment)
Or did you try the unix docker image (see https://www.bitcoin-blu.com)?

Most people can't compile by themselves, and without such good computer programming knowledge, your project will have very few people participating.

I'm working on it.
