[QUOTE="arrana, post: 243007, member: 13714"] [b]TorCoins- Possible Future Alt-coins[/b] Instead of these mining coins as you would Bitcoin and other altcoins, with TorCoins you provide band width for the Tor Network. More information on anonymity and TorCoin creation can be found in the Yale School abstract at [url]http://dedis.cs.yale.edu/dissent/papers/hotpets14-torpath.pdf[/url] From the Crypto Crimson at : [url]http://cryptocrimson.com/2014/06/torcoin-incentivizing-anonymity/[/url] [B]TorCoin: Incentivizing Anonymity[/B] June 8, 2014 The Tor network has long served as a powerful tool capable of providing users with the ability to stay anonymous online. It has also been widely regarded as a favorable way to protect user privacy while mitigating government imposed censorship. However, there are some problems with the Tor browser in its current state; with one of those being speed. This is due to the fact that the overall network speed is a direct correlation of the number of active relay nodes, all of which are derived from volunteers throughout the network. Theoretically, current network speeds could be improved upon if the number of volunteer node relays are increased. However, it is incentivizing these volunteers without jeopardizing identity that has long remained a problem with the anonymous network. This is why researchers from Yale University have come up with a concept that they believe will be the long-awaited solution to this very quandary. Enter TorCoin –an alternative digital currency based on the bitcoin protocol.[B] This cryptocurrency; however, unlike bitcoin, is based upon a proof-of-work scheme that is derived from bandwidth rather than sheer computation power.[/B] [B]How it works[/B] According to the TorCoin whitepaper, incentive is driven by to the ability to mine TorCoin by simply providing a degree of bandwidth at the network’s disposal. The coin, in return, can then simply be sold for cash on any one of the various alternative digital currency exchanges. In order to verify that a TorCoin actually represents bandwidth transferred, developers Mainak Ghosh, Miles Richardson, Bryan Ford and Rob Jansen have introduced TorPath, “a decentralized protocol for forming Tor circuits that ensures that each circuit is privately addressable but publicly verifiable.†Each circuit’s participants are then eligible to mine a select number of TorCoins, proportional to the amount of bandwidth provided. TorPath in essence, is a secure bandwidth allocation device that makes use of decentralized groups of “Assignment Servers,†which extend Tor’s existing “Directory Servers,†that are used to assign each client a specific circuit. TorPath is designed to allow for the signing of newly-minted TorCoins, which then provide the verification of each coin by anyone observing the blockchain. The issue of compensation in regards to volunteering bandwidth is what TorCoin is designed to overcome; however, the digital currency’s greatest breakthrough may be its ability to do so without sacrificing anonymity. [B]Incentive[/B] Tor developer Roger Dingledine explains: One of the main challenges with applying these ideas to anonymity systems is that there are a shocking number of ways you can screw up your anonymity. The more different incentives you add into the system, the more complex the resulting security analysis. The economics of motivating cooperating in overlay networks is already complex even before you consider security properties. TorCoin not only provides a way to incentivize those providing bandwidth to the network, but does so while offering a reliable method to distribute payment to the volunteer nodes that are essential to Tor’s existence. While preserving the anonymity of the current Tor protocol, the alternative digital currency seeks to do so while implementing verifiable bandwidth accounting; this makes it possible for the measurement of bandwidth in a way that allows for anyone to take part in the verification process. [B]Infrastructure[/B] Among other essential features of the requirements of an incentive driven system through the Tor network include, anonymous payment distribution, reliable transaction storage and incremental deployment. TorCoin consist of two protocols, TorCoin itself, and TorPath. Though the two coexist, TorCoin operates independently, which in return requires very little modification to the Tor or Bitcoin codebase. Whereas the TorPath protocol assigns specific circuits, which then authorize the minting of TorCoins through the digital currency’s use of the proof-of-bandwidth concept.
