Testnet

Practice only. Not real FUC.

These coins are not money. If you want the real public chain, stop here and use Get started. Real addresses start with fuc1…. Anything starting with tfuc1 or fucrt1 is practice.

There are two practice modes. They are not interchangeable with each other, and neither is the public chain.

1. Local practice (this computer only)

A private chain that lives on your machine. Nobody else can see it. Addresses look like fucrt1…. The wallet opens at http://127.0.0.1:8765.

./scripts/ui/start.sh

You are the only miner, so Mine usually works immediately. That is a demo, not public FUC. Leave the Terminal window open (Ctrl-C stops it).

Same thing from the command line:

./build/bin/bitfucd -regtest -daemon
./build/bin/bitfuc-cli -regtest createwallet miner
./build/bin/bitfuc-cli -regtest -rpcwallet=miner getnewaddress

Datadir default: /tmp/bitfuc-mine-regtest. You can wipe it and start over.

2. Public testnet (fake coins, shared)

A shared practice network with the same rules as public FUC, labeled NO VALUE. Addresses look like tfuc1…. Do not treat a tfuc1 balance as the same thing as a fuc1 balance.

Field	Testnet
Address	`tfuc1…`
P2P / RPC	27333 / 27332
Genesis	21374e341b93a54c0899595c8118ade1ee4d3439a750755949167202be8aef2c
Money rule	Same 1e9 cap, 2-minute blocks, 2% fee burn — still not money
Difficulty	ASERT + min-difficulty (test only)
Peers	`docs/testnet-peers.md`

./scripts/testnet/start-operator.sh
bitfuc-cli -testnet createwallet miner
python3 contrib/bitfuc/solo_mine.py --chain test --address "$ADDR" --blocks 1
bitfuc-cli -testnet addnode HOST:27333 add

Replace HOST with a peer from docs/testnet-peers.md. Never forward RPC.

How to tell them apart

Looks like	What it is
fuc1…	Public BITFUC — the real chain. Get started.
tfuc1…	Public testnet on this page. No value.
fucrt1…	Local practice on this computer. No value.

Bitcoin addresses start with bc1. Do not mix any of these.
