[ANN] Bitflash (BTF) — Satoshi's Bitcoin reborn: CPU-mined (RandomX), anonymous,

[Bitflash-sh]

Bitflash is a faithful revival of the original 2009 bitcoin-0.1.0, rebuilt for today with two changes: memory-hard CPU mining, and anonymous addressing that hides your IP and works behind CGNAT.

── What's different ──
• RandomX proof of work — CPU-only, ASIC/GPU-resistant. One CPU, one vote.
• .btf anonymous addresses over Nostr — self-certifying, Tor-onion-style, built into the coin. Your IP is never exposed to peers.
• Works behind CGNAT — no public IP, no port forwarding. Nodes rendezvous through a relay that only sees end-to-end-encrypted ciphertext.
• Automatic peer & relay discovery — zero config.
• Fair launch — no premine, no ICO, no dev reward.

── Specs ──
Ticker: BTF | PoW: RandomX (CPU) | Reward: 50 BTF, halving | Max supply: 21,000,000 | Block time: ~2 min | Windows (GUI) + Linux (headless)

── Download & run ──
Windows: unzip, run bitflash.exe → Options → Generate Coins.
Linux: extract, run build-linux.sh, then ./src/bitflash-node -gen

Disclaimer: Experimental software in the spirit of the original Bitcoin. The network is young — run it, mine it, help keep it alive, but don't rely on it for anything critical and don't put in more than you can lose.

Readme looks pretty LLM-heavy with all the em-dashes and emojis.
But it somehow works.I did notice an address rotation for each transaction.
Will it be possible to explore the blockchain? Most new bitcoin-like coins are post-quantum. Does that
not matter with the privacy here?

no connections

That would be weird. I had two nodes running.

Been running a node since launch. A few observations:

Builds and runs fine on Ubuntu first try. Got connections within minutes and found blocks early on. Address rotation per block is expected bitcoin-0.1.0 behavior. Your wallet holds all the rotating addresses, coins are all spendable from the same wallet.dat.(I think)

The .btf tunnel connections are hit or miss. Peers are discovered fine via Nostr but the rendezvous handshake fails most attempts before occasionally going through. Once connected, block sync works. Running two nodes (Linux + Windows) and they do eventually find each other and reconcile chain splits on their own.

Network went through a difficulty spike early on that caused a long stall. Blocks were coming faster than the 2min target initially which pushed difficulty up, then when hashrate dropped it stalled. Recovered on its own after a while. Worth knowing if you're expecting steady block times early on.

Running a relay at relay.cyprus-draco.ts.net:443 if anyone needs it. The -announcerelay flag works but the announcement seems to depend on relay.nostr.band which has been unreliable. Other nodes eventually discovered it anyway through the other Nostr relays.

Explorer would be useful. The blockchain is parseable but there's nothing built yet.

using the Linux (headless) how to open wallet to view balance?

[vicnas]

I don't think it's possible but you can parse your logs to count ur blocks.
But if you have a machine running windows, it' simpler.
