Like in BitCoin, only at minting stage would you need to generate payment tokens. In fact, the tokens could be generated by Tor developers themselves as we implictly trust them when we verify the signed code on official released packages. This would do at least initially. The problem would be with overhead of network tracking transactions to prevent double spending. That would be probably prohibitive, as currently BTC tranactions take some time to clear. It's probably a stupid idea. > I do hope that verifying the hashcash is then factors lighter than > generating it. Do note though that some Verifying is easy, preventing double spending without centralism is hard. > If the source has to do it you are going to transfer a bit of text from > the source to the intermediary node and thus the intermediary node might > learn that way what the real source is. The idea is that you have to spend some tokens if you want to push a lot of data (or else there would be backpressure/throttling), which you would have to earn by being a good relay or exit. > I don't think this is very viable, even though it has merit, I would > say, change the subject line and go for a proposal and we'll see how far > it can solve something. -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE _______________________________________________ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
