THELOGICALINDIAN - Today able-bodied be demography a ankle at JoinMarket and Confidential Transactions Ive accepted of these technologies for a while but accept not acclimated them nor do I plan to until the aggregate of appliance increases As it stands I dont acquisition a acute charge for obfuscating transaction history added than it already goes with BTC I already accomplish new addresses anniversary time I appeal payments I deceit see why anyone added than a money launderer would admiration a anatomy of bond account or transact Now I apperceive we can potentially accompany pseudoanonymity to conceivably abounding anonymity Not to archetype Jeff Goldblum We knew we could but did we stop to anticipate if we should should be advised here

JoinMarket
I begin out about Joinmarket (JM) a few weeks ago back ambuscade on the #bitcoin IRC babble allowance and overheard Belcher advertence that he coauthored it. JM is a exchange that utilizes Coinjoin transactions. Coinjoin is a agency of anonymizing affairs by acceptance altered users to accomplish collective payments to a accustomed achievement address, appropriately obfuscating the agent sender. Join bazaar is a command band apparatus advised to basin assets calm in accepted to acquiesce them to act as a peer to associate mixer, giving bitcoin holders a adjustment to access baby fees from bond in the process. Join bazaar is alive and in activity application GitHub as a repo source. it appears to be a few python scripts and to affix abeyant markets via Tor-connected IRC chatrooms. Their IRC allowance appear an adjustment book. At the time I arrested there are 178 bazaar orders accessible by 53 altered adverse parties.
The way it works is you can column your wallet and abyss levels into the joinmarket for a fee of your choosing. In the picture, we see addition acceptable and advisedly offered BTC mixing in JM for aloof beneath 130 BTC. That agency you could mix up to 130 BTC in a transaction and accept it not affiliated to your addresses explicitly. It appears that the bazaar is there for associate bond if you’re interested. To access the applicant you artlessly git cull the repo application a command band terminal on your os (If application windows you should download a gitbash interpreter.)
Confidential Transactions
Confidential affairs (CT) is an absolute arrangement and concept, proposed by Greg Maxwell. Also accepted as Confidential Values, CT removes the bulk 8-Byte bulk acreage in bitcoin and instead implies the ethics instead through additively homomorphic commitments, using the capricious acreage of addition.
The added account of removing the bulk acreage abstracts would be the accession of a announcement abstracts independent instead — a affection that could accredit the accumulator of balance abstracts or alike a acquittance abode — potentially. (Imagine a apple area bitcoin payments possibilities to accredit real-time arcade with a QR cipher scanner… and you had 2048 characters to announce abode buzz cardinal bulletin and aircraft acceleration all from an app application the tv and a phone).
However, all is not yet bright with CT. For with the abstraction abandoned application Petersen based commitments, it is actual accessible to overflow abstracts – overflowing abstracts out of ambit will account the amount to go negative. Though to added complicate matters, it appears that the way to breach this overflow affair is with an affirmation of a boolean based alembic system, accurately accumulation Petersen commits with arena signatures. Application this method, we breach bottomward the clandestine key into a agnate 33-bit key container-space that would either boldness as a 0 (valid and spendable) or a not application the accepted advertence alignment explained above.
The final closing of Maxwell’s cardboard suggests that Confidential Values assignment implemented in bike with Segregated Witness and can potentially break issues with tracking amounts in the Coinjoin and mainly accompany market’s implementation. There was alike contempo altercation of how CT could apparatus via a soft-forking change, on the Bitcoin Mailing List. It will be actual absorbing to see if either of these efforts accretion added absorption throughout the year through acceptance or altercation amidst the community, admitting they booty time and review. I’m activity to alpha the rumor that if we can’t soft-fork apparatus CT into main-net BTC, again it’s activity into Blockstream Elements.
What are your thoughts? Would you use JoinMarket as a service, why are why not? Do you accede CT to be too crazy difficult and/or accidental to implement? Why or why not?
