Re: [Bitcoin-development] Getting trusted metrics from the block chain in an untrusted environment ?
My program should run on lightweight/embedded hardware. The execution environment provides access to the Bitcoin network but not enough resources to set up a trusted node along with my program. So you want to 'benefit' from the network without contributing to it ? I would need a way to ask an untrusted Bitcoin node to compute some 'metric request' on my behalf and having the result of that metric request validated by the network. Not going to happen - why would anyone be interested in providing you 'free compute resources' ? Is there any available or work-in-progress projects that would come close to this need ? Or should I do it myself ? :-) Setup a node, create an API interface and have your 'app' use your API on yoru node :p Rob -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.

[Bitcoin-development] Getting trusted metrics from the block chain in an untrusted environment ?
Hello all, I'm designing a program that needs some metrics computed from the Bitcoin block chain (some address balances, or the occurrence or not of a specific transaction). The kind of infos you get from http://blockchain.info/, provided you trust this website (my program do not). My program should run on lightweight/embedded hardware. The execution environment provides access to the Bitcoin network but not enough resources to set up a trusted node along with my program. Also, my program trusts the global Bitcoin network but no individual node. I would need a way to ask an untrusted Bitcoin node to compute some 'metric request' on my behalf and having the result of that metric request validated by the network. Is there any available or work-in-progress projects that would come close to this need ? Or should I do it myself ? :-) Thank you all, Clément Elbaz -- Rapidly troubleshoot problems before they affect your business.

Re: [Bitcoin-development] Getting trusted metrics from the block chain in an untrusted environment ?
Some more thoughts : If no such project exist yet, I thought it could work with an alternate, small and fixed-length 'metric request block chain' of some sort. It would temporarily stores structures defined as [metric request | current block number when request was made | hash of the response] instead of financial transactions. These structures are verifiable so it could work the same way as a regular financial blochchain. It should not be part of the main Bitcoin protocol but could be a plugin interacting with the data managed by the fullnode bitcoin software. Also, metrics requests can be expensive to compute and validate, so it would make sense to pay a fee everytime you ask one. Does any of this makes any sense to you ?
