The answer @jstnryan gives is fairly complete. I'd only add that cruzbit exists because for a long time I thought about what an even more simple and easy to use (and more modern!) bitcoin would look like. For example, I don't think the UTXO design is necessary and it adds more complexity than value. Similarly, given the vast majority of transactions are simple standard scripts which effectively transfer value from one public key to another, the scripting system seemed a bit silly. So I got rid of both of those things. And like has been said, I made all protocol messages and primitives JSON for ease of use. I'm not trying to innovate with flashy new bells and whistles. It's an attempt to refine an already amazing idea. I don't know if I succeeded in the eyes of others but I'm happy with the result. Thanks for even taking the time to read about cruzbit!

Currently the project doesn't distribute any binaries. It is really simple to create your own and much safer!

This update is to announce that OpenCL mining support is now available!

Please see the project README for instructions to enable it in your build.

We're still solo mineable for the time being. Thanks!

Just wanted to update this thread to let everyone know that cruzbit is currently being traded on the qTrade exchange: https://qtrade.io/market/CRUZ_BTC

Also the estimated current network-wide hashrate is ~100 GH/s. Still solo mineable!

Bumping the thread to announce that the qTrade exchange has enabled cruzbit trading!

Also, the cruzbit client now has built-in mining support for Nvidia GPUs!

Thanks for your interest!

Hey!

To start mining, follow the steps here: https://github.com/cruzbit/cruzbit#getting-started-mining

If you're running Linux, someone created a nice cheat-sheet for building the binaries: https://gist.github.com/setanimals/f562ed7dd1c69af3fbe960c7b9502615

Hello everyone,

I'm a long time bitcoin fan/user. For years I thought about rewriting bitcoin to be as simple as possible. There is a fair amount of complexity to the canonical bitcoin implementation that didn't strike me as strictly necessary. It makes understanding and working with the protocol difficult. I had some time recently, so I finally decided to implement what I thought was the simplest version of bitcoin that could exist. cruzbit is what I ended up with.

Project: https://github.com/cruzbit/cruzbit

More details: https://medium.com/@asdvxgxasjab/cruzbit-a-simple-decentralized-peer-to-peer-ledger-2944495b6129

In addition to simplicity, I wanted everything I used to be standard. I wanted an average developer to be able to run cruzbit and immediately start working with the protocol and talking to their client.

Highlights:

    Newer crypto: Ed25519 and SHA3
    Simplified transaction format: No inputs/outputs. No scripts.
    No UTXO: Account-model, but as far as I can tell, a novel simpler approach to it. No serial per-account nonce.
    No fixed block size limit: A variation of BIP 101 is implemented.
    Reference implementation is in Go. Completely new code base.
    Web/dev-friendly peer protocol: secure WebSockets and JSON for all protocol messages and primitives.


No premining or any of that funny business. The memo field of the coinbase transaction of the genesis block is timestamped with the bitcoin blockchain's tip block hash at the time of its creation. It's being CPU mined at the moment.

Any/all feedback is much appreciated. Would love to have some new miners join us. Take it easy!

Haha awesome! Thanks so much for your patience. And welcome to the cruzbit network!

Hmm strange and sorry again. I'll have to give it a try with that version on ARM. So far I've tested Windows, Linux (amd64), and MacOS only.

If you omit/unset GO111MODULE it should install, it just won't respect the module versions but at the moment that should be fine.

Thanks so much though!

I'm sorry about that!

If you're still up for giving it one last shot, this might work:


It also requires Go version 1.11+
