Research: Bitcoin inflation loopholes still exist, 60% of Bitcoin is or affected by the entire node

According to foreign media reports, according to Bitcoin node statistics released by Bitcoin Core developer Luke Dashjr website, 60.22% of Bitcoin's full-node software is still vulnerable to inflation.

According to the report, software running on 60,101 bitcoin nodes is vulnerable to the CVE-2018-17144 vulnerability. As CoinTelegraph reported at the end of September last year, the vulnerability allowed malicious miners to artificially increase the supply of bitcoin through simple double input.

According to an analysis by Cointelegraph, it is likely that the existence of the vulnerability could have catastrophic consequences. At that time, the developer decided to keep it secret and only revealed that the vulnerability made the network vulnerable to distributed denial of service (DDoS) attacks. After the vulnerability was fixed, the developer then fully disclosed the danger of the vulnerability.

Statistics on the Dashjr website also show that as of press time, Bitcoin has a total of 99,638 full nodes running, which is about 10 times higher than the number reported by most Bitcoin analysis platforms. For example, BitNodes claims that there are now 9515 bitcoin nodes, and CoinDance reports that as of press time, only 9391 nodes are running.

The Next Web, a technology news media, quoted Dashjr's previous explanation as saying that this difference is actually due to the fact that most of these platforms only include listening to the full node. However, according to the report, whether the node is "listening" is an almost irrelevant technical detail.

According to The Next Web, one result of the node "listening" is that it is more visible and easier to find. According to reports, Dashjr explained that “those economic nodes that handle transactions can neither monitor nor listen.” The report concludes:

“Frankly, just focusing on listening nodes is not a very useful metric, and non-listening nodes are equally important.”

Dashjr's Bitcoin node graph is based on four weeks of data and is updated every hour.

In early February of this year, EOS.io, the development company responsible for EOS, the fourth-largest cryptocurrency market, has provided vulnerability bounty for five key vulnerabilities this year.
