Dear PascalCoin users,
New PascalCoin Build 3.0.0
### Build 3.0.0 - 2018-05-02
- Implementation of Hard fork on block 210000
- PIP - 0017: Anonymity via transaction mixing (multioperation)
- MultiOperation: PIP-0017
- Multioperation allows a transactional like operations, they can include transactions and change info operations in a signle multioperation
- Allow to send coins from N accounts to M receivers in a transaction mixing, without knowledge of how many coins where sent from "Alice" to "Bob" if properly mixed
- Ophash can be previously known by all signers before signing. They must sign only if multioperation includes it's transactions as expected
- OpHash of a multioperation will allow to include n_operation and account of each signer account, but md160hash chunk will be the same for all
Have to comment on this "mixing".
People are not to trust this too much.
This paper is a nice read for those experimenting with coin mixing:
"When the cookie meets the blockchain" !
https://arxiv.org/pdf/1708.04748.pdfIt's been mentioned on slashdot.org
https://yro.slashdot.org/story/17/08/21/2038239/third-party-trackers-on-web-shops-can-identify-users-behind-bitcoin-transactionsA disturbing quote from the paper's introduction:
"
Our second attack shows that
if the tracker is able to link two purchases of the same user to the
blockchain in this manner, it can identify the users entire cluster
of addresses and transactions on the blockchain, even if the user
employs blockchain anonymity techniques such as CoinJoin. The
attacks are passive and hence can be retroactively applied to past
purchases. We discuss several mitigations, but none are perfect
"
CoinJoin is a bitcoin mixer.
