Zerolink Claims to Have Developed Fully Anonymous Bitcoin Payments

 Zerolink has claimed to develop a method for facilitating  fully anonymous bitcoin payments. Zerolink comprises a collaboration  between developers from privacy-centric wallet services Samouraiwallet  and Hiddenwallet. 

Zerolink Claims That Its “Wallet Privacy  Framework” And “Chaumian Coinjoin” Mixing Techniques Are Able to Ensure  Anonymous Bitcoin Payments

 Zerolink has claimed to  successfully have developed a method for facilitating fully anonymous  bitcoin payments. Zerolink says that its “Wallet Privacy Framework” and  “Chaumian Coinjoin” mixing techniques are able to ensure the privacy of  transactions and remain impervious to network analysis. 

 The mixing technique employed by Zerolink to ensure anonymous bitcoin  transactions expands on the work of Gregory Maxwell, who in 2013  conceived “Coinjoin”. “Using chaum blind signatures: The users connect  and provide inputs (and change addresses) and a  cryptographically-blinded version of the address they want their private  coins to go to; the server signs the tokens and returns them. The users  anonymously reconnect, unblind their output addresses, and return them  to the server. The server can see that all the outputs were signed by it  and so all the outputs had to come from valid participants. Later  people reconnect and sign.” 

Zerolink Claim That Their Anonymizing Process Can Be Conducted in Seconds, Whilst Incurring Minimal Fees

 By using the ‘Chaumian Coinjoin’ process, Zerolink claim that they are  able to conduct a “mixing round within seconds,” and that the process is  “fairly cheap”. The company also states that the high transaction fees  presently associated with bitcoin transactions have allowed them to  develop “an elegant way to make it uneconomical for malicious actors to  disrupt mixing rounds.” 

 Both Samouraiwallet and Hiddenwallet have announced that they are  “fully committed to implemen[ting]” the Wallet Privacy Framework into  their services. Despite the theory underpinning the Zerolink’s mixing  technique having existed for years, the company claims to be the first  to sucessfully implement such due to the challenges required to develop  ddos protection.
