Because turning on SSL gives pool operators a way to hack your miners. http://www.symantec.com/connect/blogs/openssl-patches-critical-vulnerabilities-two-months-after-heartbleed Just because SSL is the answer for financial services regulated security theatre, where fraud means you just roll-back the transaction, it does not mean it is actually a good cryptographic solution. There are far better mechanisms that could be implemented using ECDSA keys (aka bitcoin addresses) to authenticate both miners and pools, but the problem is there zero economic incentive to do so. As long as the BGP/SSL/zero-day-of-the-week man-in-the middle fraud cost is lower than the engineering cost to do some real cryptography and code audits, we'll keep having new 'security patches' every couple of months. ------------------------------------------------------------------------------ _______________________________________________ Bitcoin-development mailing list Bitcoin-development@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bitcoin-development
