The kind of infos you get from http://blockchain.info/,\nprovided you trust this website (my program do not).\n\nMy program should run on lightweight/embedded hardware. The execution\nenvironment provides access to the Bitcoin network but not enough resources\nto set up a trusted node along with my program. Also, my program trusts the\nglobal Bitcoin network but no individual node.\n\nI would need a way to ask an untrusted Bitcoin node to compute some 'metric\nrequest' on my behalf and having the result of that metric request\nvalidated by the network.\n\nIs there any available or work-in-progress projects that would come close\nto this need ? Or should I do it myself ? :-)\n\nThank you all,\n\nClément Elbaz\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20140108/2a00a136/attachment.html\u003e"}
