Topic: What`s the deal with the testnet? (Read 267 times)
It is really useful information, thanks
Has anyone notice this? Today one miner has been mined almost all blocks on testnet. And he has not including any segwit transactions in the blocks! My test transactions have not been confirmed since 6 hours ago!

I am a bit worry of this type of attack could deal a great damage to Bitcoin Mainnet!
It can't do anything to mainnet since testnet is a completely separate network with almost 0 hashrate. The only reason this can happen on testnet is because someone has the majority hashrate. https://live.blockcypher.com/btc-testnet/tx/b80f9a8aa0e3a636c517072597b945cee4d878d9f645d19a8666dc6f6ca91d31/

I also noticed a lot of outputs that are created are spent inside the same block (this is probably part of the attack logic). But i didn`t know this is possible (seeing those tx it clearly is). Can you confirm this?
Yes, it is possible to spend output in the same block it has been originated. This is actually quite normal.
Thanks, man! I realized something was fishy and I do manage to get txs through if i set the fee high enough.
I would have though that if this was a legitimate stress test or some kind of experiment the people behind it would have made some announcement. you said that this has been going on for a month, i suspect that this is some kind of spam attack. on the other hand, for testing purposes i could also use regtest net.

Testnet3 is being flooded by 1 or a handful of individuals, probably not even for malicious purposes but to stress test the network. somebody with a few thousand coins can tie up testnet for a long time. its been happening for about a month, a lot of testnet services shut down, primarily the faucets.
looks like it will end eventually, or a new testnet will be released. in the mean time, use high fees and WAIT. ive been having a hell of a time finding coins and being able to get transactions to be accepted in a block, but not much anybody can do aside from using super high tx fees so you can get accepted in a block .

I have started testing stuff on the testnet for a week now and I have this question:
Wtf is bloating up the blocks? I see most blocks being full, up to 1mb, and bloated up by a chain of txs that are spent in the same block: as soon as one output is created it is spent in the next tx and so one in a long chain of txs. What is this?
Also what advice would you guys give to a newcomer when working with the testnet? (i have worked with ethereum extensively before and i know how btc works but i haven`t touched the tools much before; atm i am experimenting with bitcoind and bitcoinjs-lib)
