E-Cash from Bitcoin

  title={E-Cash from Bitcoin},
  author={Ian Miers and Christina Garman and Matthew Green},
Bitcoin is the first e-cash system to see widespread adoption. While Bitcoin offers the potential for new types of financial interaction, it has significant limitations regarding privacy. Specifically, because the Bitcoin transaction log is completely public, users’ privacy is protected only through the use of pseudonyms. In this paper we propose Zerocoin, a cryptographic extension to Bitcoin that augments the protocol to allow for fully anonymous currency transactions. Our system uses standard…

Bitter to Better - How to Make Bitcoin a Better Currency
An in-depth investigation is performed to understand what made Bitcoin so successful, while decades of research on cryptographic e-cash has not lead to a large-scale deployment.
Two Bitcoins at the Price of One? Double-Spending Attacks on Fast Payments in Bitcoin
This paper analyzes the security of using Bitcoin for fast payments, where the time between the exchange of currency and goods is short, and proposes a lightweight countermeasure that enables the detection of doublespending attacks in fast transactions.
An Analysis of Anonymity in the Bitcoin System
It is shown that the two networks derived from Bitcoin's public transaction history have a non-trivial topological structure, provide complementary views of the Bit coin system and have implications for anonymity.
Bitcoin: A Peer-to-Peer Electronic Cash System
A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide
Compact E-Cash
This paper presents efficient off-line anonymous e-cash schemes where a user can withdraw a wallet containing 2 coins each of which she can spend unlinkably, and offers exculpability of users, that is, the bank can prove to third parties that a user has double-spent.
Universal Electronic Cash
The main advantage of the new system is that the customer can subdivide his cash balance into many pieces in any way he pleases until the total value of all subdivided piece equals C.
Untraceable Electronic Cash
An electronic cash protocol including the steps of using a one-way function f1 to generate an image f1 (x1) from a preimage x1 and receiving from the second party a note including a digital signature.
Quantitative Analysis of the Full Bitcoin Transaction Graph
This paper answers for the first time a variety of interesting questions about the typical behavior of users, how they acquire and how they spend their bitcoins, the balance of bitcoins they keep in their accounts, andHow they move bitcoins between their various accounts in order to better protect their privacy.
Auditable, Anonymous Electronic Cash Extended Abstract
Most anonymous, electronic cash systems are signature-based, which means that in these systems the bank has the technical ability to issue unreported, valid money.
Efficient Accumulators without Trapdoor Extended Abstracts
In 1994 Benaloh and de Mare introduced the notion of one way accumulators that allow to construct efficient protocols for proving membership in a list and related problems like time stamping and authentication as no central trusted authority is (should be) needed.
