Several Bitcoin developers are furious at a fellow Bitcoiner who admitted to “griefing” one of Bitcoin’s testnets by generating three years worth of blocks in a single week, forcing some developers to halt the applications they were testing.
“Whoever has been fucking with testnest is a douchebag looser,” <a href="https://x.com/francispouliot_/status/1784937565205737910" target="_blank" rel="noopener nofollow">said</a> Francis Pouliot, a founder at noncustodial Bitcoin (<a href="https://cointelegraph.com/bitcoin-price">BTC</a>) exchange and payments firm Bull Bitcoin. “Cool bro you’re able to attack a network with no economic incentives and literally the only damage done is fucking with the tests of open-source Bitcoin application builders and wasting their time,” he added.
Pouliot didn’t realize until later that it was Jameson Lopp, a cypherpunk and a founder at digital asset self-custody solution Casa, who had identified himself as the culprit the day before in an April 28&nbsp;<a href="https://njump.me/nevent1qqsv23cmpg5jym2grz45psr43dwxs9r88ul40sum8v6uxxhhe95ha9qzyrmj3k0xuuzgxk88pyc0tjnykzthwrvcnnxcdp20ucvwm2wg5wqsvrg0xh4" target="_blank" rel="noopener nofollow">post</a> on decentralized social media platform Nostr. 
Lopp said his griefing attack resulted in over 165,000 blocks (three years worth) generated on Bitcoin’s testnet in a single week, which only cost about $1 worth of electricity.
However, Lopp argued that the “trivial exploit” — which required just 20 lines of code — highlights a weakness of the testnet that he raised before.&nbsp;
“I’m championing a cause, and sometimes you have to do more than send an email to get people’s attention.”

Hash rate and difficulty&nbsp;<a href="https://mempool.space/testnet/graphs/mining/hashrate-difficulty" target="_blank" rel="noopener nofollow">data</a> on the Bitcoin network testnet showed <a href="https://cointelegraph.com/explained/what-is-bitcoin-hash-rate-and-why-does-it-matter">hash rate spiking to</a> 2,315 terahashes per second (TH/s) on April 19 before returning to 86 TH/s on April 30, <a href="https://mempool.space/testnet/graphs/mining/hashrate-difficulty" target="_blank" rel="noopener nofollow">according</a> to mempool.space.
However, Pouliot and a few others see Lopp’s actions differently, arguing it’s akin to someone “taking a shit” in a jacuzzi just to get people to “move to another spa” — likely referring to testnet4.&nbsp;

 This is what it looks like trying to sync a testnet3 node right now. There are thousands of new blocks per hour, so no matter how fast you sync, you can never reach the tip.

A member in the Bitcoin Talk Thread <a href="https://coinfaucet.eu/en/btc-testnet/" target="_blank" rel="noopener nofollow">said</a> Lopp’s actions have ignited a “testnet war,” arguing that people like Lopp should be excluded from Bitcoin’s testnet and even went as saying Lopp is a “general security risk for Bitcoin as a whole.”

Lopp <a href="https://x.com/lopp/status/1784958968168628265" target="_blank" rel="noopener nofollow">said</a> he wants to see Bitcoin’s testnet reset to fix the testnet “timewarp” weakness and to restore mining rewards earned from the testnet, which he noted is practically zero now.
