Quote from: knightmb on July 25, 2010, 19:44:02 If I figure out that Public Key 123456 generates Hash ABCD and Public Key 654321 also generates Hash ABCD I’m still left without the Private Key. But from what you are saying, all I need is Public Key 654321 and I can […]

You stopped my post just in time! 🙂 Red, thanks for telling me privately first!  Please go ahead and post it (and relieve the suspense for everyone!) His point is that transactions paid to a Bitcoin Address are only as secure as the hash function.  To make Bitcoin Addresses short, […]

I think there is a pretty significant crypto flaw in Bitcoin as currently implemented. I’m not sure it is exploitable now (I’m not a real cryptohacker) but it is more than plausible that will be in the near future. The flaw would enable anonymous stealing of coins from arbitrary bitcoin […]

Please upgrade to 0.3.3!  Important security improvements were made in 0.3.2 and 0.3.3. New features: – Gavin Andresen’s HTTP authentication to secure JSON-RPC – 5x faster initial block download, under 30 minutes Related posts: Re: Bitcoin 0.3.2 released Anyone know where the changelist is, I’m curious to what… Re: Bitcoin […]

Was that on the test network? http://bitcointalk.org/index.php?topic=363.0 No. Please do these tests on the test network.  That’s what it’s for.  Thanks.

I have seen some speculation about scalability and denial of service by spam transactions in the IRC channel so I thought it would be a good idea to try a test. I set up a stupid little bitcoind script on a couple of my linux machines to send 1000 tiny […]

I’m trying to understand the way Bitcoin stores block data – among other things I want to run some statistics on the block chain / transaction history and check just how anonymous Bitcoin really is.  So I went to the source to see how Bitcoin reads/writes block data to file. […]

Please test 0.3.2.5 in preparation for the 0.3.3 release!  This build is looking good and should be the one that goes into 0.3.3.  I encourage you to go ahead and upgrade now if you’re on Windows or Linux. New features: – Gavin Andresen’s HTTP authentication to secure JSON-RPC – 5x […]

Don’t use the -server or -daemon switch or run bitcoind on a machine where you use a web browser.  It opens port 8332 on 127.0.0.1, the local loopback address, and you wouldn’t think that web browsers could cross-site access it, but it is possible. We’re working on a release soon […]

Weird I guess fopen() in php dies if the response is 500? It seems like errors such as invalid address should just be normal replies just not “sent” so we can just check the reply string. I think of 500 errors as the server itself having an error. Can anyone […]
