Title: [2017-06-17] New Dandelion Proposal Aims to Anonymize Bitcoin Transaction.. Post by: Terraformer on June 17, 2017, 05:05:55 AM Back in February a new privacy white paper for the Bitcoin network called ‘Dandelion’ was published and received a lot of attention from the bitcoin community. Now the researchers and programmers involved with the idea have submitted a Bitcoin Improvement Proposal (BIP) to the bitcoin developers list for feedback and review.
A New Proposal Called ‘Dandelion’ Hopes to Redesign the Bitcoin Network for Anonymity Dandelion is a concept designed by the Zcash advisor and developer Andrew Miller and a team of University of Illinois researchers. A few months ago the team released its white paper ‘Dandelion: Redesigning the Bitcoin Network for Anonymity.’ The project is a new type of transaction broadcasting method that aims to stop people snooping and locating Internet Protocol addresses (IP). Essentially transactions relayed to nodes go through a few hops followed by a symmetric broadcast sent to other nodes which cannot identify the original IP source. According to the recently submitted Github proposal Dandelion works in two phases. “[The first phase] is the “stem” phase, and then “fluff” phase,” explains the Dandelion BIP. “During the stem phase, each node relays the transaction to a *single* peer. After a random number of hops along the stem, the transaction enters the fluff phase, which behaves just like ordinary flooding/diffusion. Even when an attacker can identify the location of the fluff phase, it is much more difficult to identify the source of the stem.” Read more: https://news.bitcoin.com/dandelion-bitcoin-anonymize-transaction-broadcasts/ |
