Bitcoin Testnet Faucet from BAC (v3.0 & v4.0 available)

Just let me know how much Bitcoin Testnet you want, why you need it, which version you're after, and your Bitcoin Testnet wallet address. I've got both v3 and v4 Testnet coins ready to go. Make sure to specify which one you want. I can hand out full coins too. Also, we've got an automated faucet up and running for both versions 3 and 4. No KYC needed to use it, super simple and relaxed: https://altquick.com/faucet/ If you're looking for more Testnet coins than what's typically handed out for free, check out our other options: You can buy or sell Bitcoin and other altcoins anonymously without any account or KYC here: https://altquick.com/swap/ Or, if you prefer using an account, you can buy or sell with our main exchange’s bid/ask: https://altquick.com/exchange/.

Is it testnet4 or testnet3?

I only have v3.0 atm. I'm not touching 4.0 until she's in Core. Edit: I now have both Testnet4 and Testnet 3 coins available.

Release candidate for v28.0 already contains testnet4: https://groups.google.com/g/bitcoindev/c/EmAOO-Nbmzw Let's see, if you can handle coinbase transaction properly. Because if someone will send it into your exchange in this way, then it is not counted.

I'll wait it out. Did the v4.0 testnet get hit by a similar Lopp attack just a few days ago? We apparently do not handle that right.  I'm not seeing anything exchange side for those deposits. Good ole testnet... testing shit and creating more work.  We will get that patched first thing in the morning.

1. No, but few days ago, there was just a regular testnet3 blockstorm. To trigger it, all that is needed, is mining every 2016th block, with the minimal difficulty. Any CPU miner can trigger that kind of attack. And if no ASIC will find a block in 20 minutes, then it will happen automatically. 2. Testnet4 is resistant to that. There is some discussion about "7200 seconds rule vs 600 seconds rule", but it is about timewarp attacks. Blockstorms are already fixed. Of course, addresses assigned to users are different. For example: https://mempool.space/testnet/tx/69564bc22744b4cf78c348d25b23017f7e9c63ca2f01070fbc8d288402912efc Your code can sweep it, but it is never assigned to any user's account. Which means, that miners cannot "mine on exchange's address", but they have to use their own addresses, accumulate coins, and then do a separate transaction for deposit.

I'm not sure I understand.  I'm fairly confident I've mined to exchanges just fine in the past.   I don't see any reason those coins straight from the Coinbase shouldn't be seen as normal.  Obviously, there is more to it than what I see. Good news on the v4.0 fixes.

You should technically be able to use an address from your exchange account to mine into without a problem, however some exchanges don't accept it because they are too lazy to change their backend to handle the "special cases". As you may already know in PoW coins like bitcoin the coinbase output needs to mature for a certain number of blocks (100 blocks deep for bitcoin) to become spendable. Exchanges usually spend what they receive a lot sooner than that.

We got it patched and fixed up. People are welcome to mine to their address... go for it. Thanks for the Coinbase tips <3.

I now have both version 3 and 4 Bitcoin Testnet coins available. Please just let me know what version is needed when the request is made. I forgot to mention that this was long since patched and your coins were credited to your account. People are more than welcome to mine directly to their address on our website. We handle these transactions now <3.  Thank you for noticing that. Please let me know if you see any other fuckery.

I can provide multiple coins in needed.  Just ask.

Please post here rather than PM me.  Thank you! I have plenty of v3 and v4 Bitcoin Testnet.  (No Signet... I thought those could be made out of thin air(?).)

No, they are also mined. However, all signet blocks are signed, which means, that only developers can mine them. Of course, you can make your own signet, and then it depends, what challenge will you put as "signet challenge", which will then be required in every coinbase transaction. So, signet is just "testnet with restricted coinbase", where you have to sign your block, before you start mining. Edit: https://en.bitcoin.it/wiki/Signet

Decentralized people lobbying for centralized testing seems so icky. I think I'll stick to Testnet.

People can use the faucet at https://mempool.space/testnet4/address/tb1q0dzcgv7scppjxsnwlzpkt02vlmc5rtr40wyjgr to fund their AltQuick account! It's a great faucet and gives a nice chunk of coins. We also have our faucet running and filled too at: AltQuick.com/faucet/

500 v3 TBTC added to automated faucet. Both automated faucets have coins available. Manual faucets still available as well for v3 & v4.  Just post if you need a few whole coins.

Still available.
