SOK: ORACLES FROM THE GROUND TRUTH TO MARKET MANIPULATION

ACM Advances in Financial Technologies

Abstract

One fundamental limitation of blockchain-based smart contracts is that they
execute in a closed environment and only have access to the data and
functionality that is either already on the blockchain or fed into the
blockchain. Thus any interactions with the real world need to be mediated by a
bridge service, which is called an oracle. As decentralized applications mature,
oracles are playing an increasingly prominent role. With their evolution comes
more attacks, necessitating a greater attention to the trust model of using
oracles. In this SoK, we systemize the design alternatives for oracles, showcase
attacks, and discuss attack mitigation strategies.

SYSTEMIZING THE CHALLENGES OF AUDITING BLOCKCHAIN-BASED ASSETS

Journal of Information Systems ISYS-19-007

Abstract

Firms transacting using blockchain-based assets and liabilities have begun to
enter capital markets in search for funding. Historically, firms have been able
to raise substantial funding without an audited financial statement, however we
project that in the future, audits will become a common requirement given
increased competition among firms, increased scrutiny from regulators, past
instances of fraud, and firms seeking an IPO. At the time of writing, accounting
firms are hesitant to accept mandates from companies that hold a significant
amount of cryptoassets primarily because the blockchain market introduces novel,
technically sophisticated, and risky propositions that auditors are unequipped
to handle. Through interviews with senior accounting professionals and
structured brainstorming meetings with a multidisciplinary team of accountants
and blockchain experts, we critically analyze the purported roadblocks to
auditing blockchain firms and map them to traditional auditing practices,
demonstrating that providing an audit opinion is challenging but not
insurmountable.

THE MIDDLEMAN IS DEAD, LONG LIVE THE MIDDLEMAN: THE “TRUST FACTOR” AND THE
PSYCHO-SOCIAL IMPLICATIONS OF BLOCKCHAIN

Frontiers in Blockchain Journal - Human-Centric Constituents in Times of
Decentralization

Abstract

Blockchain is widely regarded as a breakthrough innovation that may have a
profound impact on the economy and society, of a magnitude comparable to the
effects of the introduction of the Internet itself. In essence, a blockchain is
a decentralized peer-to-peer network with no central authority figure, which
adds information to the distributed database by collectively validating the
accuracy of data. Since each node of the network participates in the review and
confirmation of the new information before being accepted, the need for a
trustworthy intermediary is eliminated. However, as trust plays an essential
role in affecting decisions when transacting with one another, it is important
to understand which implications the decentralized nature of blockchain may have
on individuals' sense of trust. In this contribution, we argue that the adoption
of blockchain is not only a technological, but foremostly a psychological
challenge, which crucially depends on the possibility of creating a trust
management approach that matches the underlying distributed communication
system. We first describe the decentralization technologies and possibilities
they hold for the near future. Next, we discuss the psycho-social implications
of the introduction of decentralized processes of trust, examining some
potential scenarios, and outline a research agenda.

RESOLVING THE MULTIPLE WITHDRAWAL ATTACK ON ERC20 TOKENS

IEEE SECURITY & PRIVACY ON THE BLOCKCHAIN (IEEE S&B 2019)

Abstract

Custom tokens are an integral component of decentralized applications (dapps)
deployed on Ethereum and other blockchain platforms. For Ethereum, the ERC20
standard is a widely used token interface and is interoperable with many
existing dapps, user interface platforms, and popular web applications (e.g.,
exchange services). An ERC20 security issue, known as the "multiple withdrawal
attack", was raised on GitHub and has been open since November 2016. The issue
concerns ERC20's defined method approve() which was envisioned as a way for
token holders to give permission for other users and dapps to withdraw a capped
number of tokens. The security issue arises when a token holder wants to adjust
the amount of approved tokens from N to M (this could be an increase or
decrease). If malicious, a user or dapp who is approved for N tokens can
front-run the adjustment transaction to first withdraw N tokens, then allow the
approval to be confirmed, and withdraw an additional M tokens. In this paper, we
evaluate 10 proposed mitigations for this issues and find that no solution is
fully satisfactory. We then propose 2 new solutions that mitigate the attack,
one of which fully fulfills constraints of the standard, and the second one
shows a general limitation in addressing this issue from ERC20's approve method.

SOK: TRANSPARENT DISHONESTY: FRONT-RUNNING ATTACKS ON BLOCKCHAIN.

FC 2019 Financial Cryptography and Data Security, St. Kitts

Abstract

We consider front-running to be a course of action where an entity benefits from
prior access to privileged market information about upcoming transactions and
trades. Front-running has been an issue in financial instrument markets since
the 1970s. With the advent of the blockchain technology, front-running has
resurfaced in new forms we explore here, instigated by blockchains decentralized
and transparent nature. In this paper, we draw from a scattered body of
knowledge and instances of front-running across the top 25 most active decentral
applications (DApps) deployed on Ethereum blockchain. Additionally, we carry out
a detailed analysis of Status.im initial coin offering (ICO) and show evidence
of abnormal miners behavior indicative of front-running token purchases.
Finally, we map the proposed solutions to front-running into useful categories.

A FIRST LOOK AT BROWSER-BASED CRYPTOJACKING

IEEE SECURITY & PRIVACY ON THE BLOCKCHAIN (IEEE S&B) 2018 University College
London (UCL), London, UK

Abstract

In this paper, we examine the recent trend towards in-browser mining of
cryptocurrencies; in particular, the mining of Monero through Coinhive and
similar code- bases. In this model, a user visiting a website will download a
JavaScript code that executes client-side in her browser, mines a
cryptocurrency, typically without her consent or knowledge, and pays out the
seigniorage to the website. Websites may consciously employ this as an
alternative or to supplement advertisement revenue, may offer premium content in
exchange for mining, or may be unwittingly serving the code as a result of a
breach (in which case the seigniorage is collected by the attacker). The
cryptocurrency Monero is preferred seemingly for its unfriendliness to
large-scale ASIC mining that would drive browser-based efforts out of the
market, as well as for its purported privacy features. In this paper, we survey
this landscape, conduct some measurements to establish its prevalence and
profitability, outline an ethical framework for considering whether it should be
classified as an attack or business opportunity, and make suggestions for the
detection, mitigation and/or prevention of browser-based mining for non-
consenting users.

ON THE FEASIBILITY OF DECENTRALIZED DERIVATIVES MARKETS

FC 2017 Financial Cryptography and Data Security, Malta

Abstract

In this paper, we present Velocity, a decentralized market deployed on Ethereum
for trading a custom type of derivative option. To enable the smart contract to
work, we also implement a price fetching tool called PriceGeth. We present this
as a case study, noting challenges in development of the system that might be of
independent interest to whose working on smart contract implementations. We also
apply recent academic results on the security of the Solidity smart contract
language in validating our code’s security. Finally, we discuss more generally
the use of smart contracts in modelling financial derivatives.

REAL-WORLD DEPLOYABILITY AND USABILITY OF BITCOIN

Thesis (M.A. Sc.) - Concordia University, 2015

Abstract

We live in an era where Internet is one of the daily needs of human life. People
use Internet banking instead of going to banks, they use email rather than
postal mail.This leads to a robust digital way of living, but this also means
people are trusting middle companies and third parties for their online
services. The need of having a digital form of money that is not being
controlled by one entity is plain to see. Bitcoin is the first and the most
popular decentralized virtual currency. It is based on cryptographic functions
to remove the need of a central bank and regulates the generation of new units.
In this thesis, we would like to look at available tools to facilitate users in
holding and using Bitcoin by a perspective on usability and security, and then
evaluate the possibilities for a small business to accept Bitcoin payments. Our
focus is on the usability of these tools and developing a useful framework for
comparing and evaluating future tools. While many security tools have been
studied from a usability perspective, our work is the first to look at Bitcoin.

A FIRST LOOK AT THE USABILITY OF BITCOIN KEY MANAGEMENT

USEC 15 NDSS Workshop on Usable Security (USEC) 2015, San Diego, CA, USA,
February 8, 2015, Internet Society

Abstract

Bitcoin users are directly or indirectly forced to deal with public key
cryptography, which has a number of security and usability challenges that
differ from the password-based authentication underlying most online banking
services. Users must ensure that keys are simultaneously accessible, resistant
to digital theft and resilient to loss. In this paper, we contribute an
evaluation framework for comparing Bitcoin key management approaches, and
conduct a broad usability evaluation of six representative Bitcoin clients. We
find that Bitcoin shares many of the fundamental challenges of key management
known from other domains, but that Bitcoin may present a unique opportunity to
rethink key management for end users.

MONITORING SYSTEM CALLS FOR ANOMALY DETECTION IN MODERN OPERATING SYSTEMS

Software Reliability Engineering Workshops (ISSREW), 2013 IEEE International
Symposium

Abstract

Host-based intrusion detection systems monitor systems in operation for
significant deviations from normal (and healthy) behaviour. Many approaches have
been proposed in the literature. Most of them, however, do not consider even the
basic attack prevention mechanisms that are activated by default on today's many
operating systems. Examples of such mechanisms include Address Space Layout
Randomization and Data Execution Prevention. With such security methods in
place, attackers are forced to perform additional actions to circumvent them. In
this research, we conjecture that some of these actions may require the use of
additional system calls. If so, one can trace such attacks to discover attack
patterns that can later be used to enhance the detection power of anomaly
detection systems. The purpose of this short paper is to motivate the need to
investigate the impact of attack on system calls while trying to overcome these
prevention mechanisms.

Transparency has never been more important to those of us who have been in the
space for a while and others who are just getting started. As the first public
company to stake a large sum of ether (36,000 ETH), we learned firsthand about
the lack of sufficient data pipelines that made it difficult to meet certain
auditing requirements. That's when we decided to build our staking dashboard — a
custom solution that allows us to track our staking rewards, gives us direct
insight into our validators performance and aggregates data into one easy-to-use
platform saving us both time and money.

DEMOCRATIC IMPROVEMENT PROPOSALS FOR DECENTRALIZATION PROJECTS

Blockchain and DLT based systems are waiting in the wings to join the potpourri
of core technology that makes up our future digital lives. Both core internet
infrastructure technology and many DLT solutions have one thing in common: They
are developed with a diverse open source developer community and carry
significant security risk. To manage software change related risks both Bitcoin
and Ethereum have derived their own process of managing change proposals. For
Ethereum changes are discussed and agreed upon in the Ethereum Improvement
Proposal (EIP) process. However given the non-hierarchy management model, there
have been many approaches and obstacles to make this process as close to a
democratic procedure as possible. It is working, but far from perfect and there
are many good approaches and lessons learnt. EIP requires input from experts at
IETF to shape up and standardize.
