Hi,

Is the idea that SIPCoin would be built using some existing blockchain platform, or would we define a whole new blockchain platform from scratch for SIPCoin?

Regards,

Christer

Subject: [stir] SIPCoin - a new cryptocurrency for stopping robocalls

Cullen and I have just submitted this:
https://www.ietf.org/id/draft-rosenberg-stir-sipcoin-00.txt

which is a proposal for a new type of cyryptocurrency dedicated solely to preventing spam on the SIP-based phone network. It is designed to be fast, causing less than one second increases in call setup time. NOn-transferrable to avoid being a tool for fraud and avoid being tied to market whim; backed by public CAs with a new type of centralized ledger validation; trivially verifiable by receivers of calls. Also we suggest a technique for incremental deployment on the PSTN which has incremental benefits and economic benefits for each deployment phase. We've done some analysis on the economics to help motivate the solution.

WHen combined with our previous draft, and some nice whitelisting thrown in as described in here, I think this is a very interested technique to put this robocalling plague to rest.

I'm coming to London and looking forward to discussing.

Comments are, of course, welcome.
