Recently I was re-reading the following (which has been edited periodically): https://bitcoin.org/en/alerts It currently reads, "There is no ongoing event on the Bitcoin network." However, in reading the most recent alert on that page, we are (it seems) still affected by the issues discussed relative to the 4th of July event, namely: https://bitcoin.org/en/alert/2015-07-04-spv-mining This originally was formulated in alerts via discussion on bitcoin.org repository, here: https://github.com/bitcoin-dot-org/bitcoin.org/pull/933 So anyway. Getting back to this, how do I ensure that I have a safe version? Thus far I am still using the guidance here from the bitcoin.org alert shown above. For example, for Electrum, bitcoin.org not only directs users to wait 30 confirmations more than usual, but also directs users to the following resource: https://en.bitcoin.it/w/index.php?title=July_2015_chain_forks&redirect=n o This brings me to the "safe software and version." If we understand this correctly, the safe software and version will be Bitcoin Core at its most current version. Thus it is vitally important to provide a way to ensure that users do not inadvertently be misled into connecting to a XT node. However, the information (about the software and version, in banner) is provided voluntarily by the server administrators and thus isn't validated. How to make sure that you are actually connecting to one who is running Core with the proper version (and not Core with some very old version, or XT)? On the bitcoin wiki, it states in part, "During a fork, it is possible to use the Get Block Header custom plugin[3] to authoritatively determine which side of the fork an Electrum server is on." It refers to this: https://bitcointalk.org/index.php?topic=1110912.msg11800126 Depending on what wallet people are using, that is, Core, any of the other wallets... hardware, desktop, web, mobile... there would be different ways to determine what software is being used to make sure that you are using Core in the current version (and not inadvertently using XT for example). The question is, how would this be done most easily?
