This document discusses representing blockchains as graphs to enable analysis and security applications. It describes blockchains as having three main layers that can be modeled as graphs:
1) The peer-to-peer network as a graph of nodes and connections.
2) Each node's ledger as a graph showing the evolution of closed and open ledgers over time.
3) Transactions within ledgers as a graph of accounts and transactions between them.
It then provides an example use case of monitoring server security logs as a temporal graph to detect tampering by comparing graphs using similarity measures like SimRank.
Technology tipping points Big Data and Blockchain use case presentationVinod Kumar Nerella
In this presentation, I am talking about the two technology tipping points big data and Blockchain.
In big data area, the presentation covers use cases in retails, financial and manufacturing sector.
Block chain and its main concepts are explained with the use case smart contracts is introduction and Blockchain can help manufacturing firms for efficient operations.
Graphs or Networks are becoming more mainstream after Google and Facebook have shown how Graphs can be leveraged to create business value. Heterogenous information networks is a concept that I found interesting to represent nodes and relationships of different kinds. The researchers that are doing a lot of research in this area are Jiawei Han and Yizhou Sun and googling them will bring up one of their books.

Block chains are part of the underlying infrastructure for Bitcoins. They are the accounting portion of the bitcoin ecosystem. The art of the possible for block chains is to use them for a larger ledger systems.
Any digital centralized registry (e.g., health records) can be made a part of the block chain system. Much like public and private cloud infrastructure has arisen, block chain as a platform is an emerging opportunity for entrepreneurs and innovator.

Blockchain for IoT Security and Privacy: The Case Study of a Smart HomeKishor Datta Gupta
Internet of Things (IoT) security and privacy remain
a major challenge, mainly due to the massive scale and
distributed nature of IoT networks. Blockchain-based approaches
provide decentralized security and privacy, yet they involve
significant energy, delay, and computational overhead that is
not suitable for most resource-constrained IoT devices. In our
previous work, we presented a lightweight instantiation of a
BC particularly geared for use in IoT by eliminating the Proof
of Work (POW) and the concept of coins. Our approach was
exemplified in a smart home setting and consists of three main
tiers namely: cloud storage, overlay, and smart home. In this
paper we delve deeper and outline the various core components
and functions of the smart home tier. Each smart home is
equipped with an always online, high resource device, known
as ”miner” that is responsible for handling all communication
within and external to the home. The miner also preserves
a private and secure BC, used for controlling and auditing
communications. We show that our proposed BC-based smart
home framework is secure by thoroughly analysing its security
with respect to the fundamental security goals of confidentiality,
integrity, and availability. Finally, we present simulation results
to highlight that the overheads (in terms of traffic, processing
time and energy consumption) introduced by our approach are
insignificant relative to its security and privacy gains.

Analysing Data from Blockchains - Keynote @ SOCCA 2020Ingo Weber
Keynote at the Symposium on Cryptocurrency Analysis (SOCCA 2020). Content:
In order to analyse how concrete blockchain systems as well as blockchain applications are used, data must be extracted from these systems. Due to various complexities inherent in blockchain, the question how to interpret such data is non-trivial. Such interpretation should often be shared among parties, e.g., if they collaborate via a blockchain. To this end, we devised an approach codify the interpretation of blockchain data, to extract data from blockchains accordingly, and to output it in suitable formats -- see https://arxiv.org/abs/2001.10281.
In addition, application developers and users of blockchain applications may want to estimate the cost of using or op- erating a blockchain application. In the keynote, I will also discuss our cost estimation method.

IoT and Blockchain Challenges and RisksAhmed Banafa
The biggest challenge facing IoT security is coming from the very architecture of the current IoT ecosystem; it’s all based on a centralized model known as the server/client model. All devices are identified, authenticated and connected through cloud servers that support huge processing and storage capacities. The connection between devices will have to go through the cloud, even if they happen to be a few feet apart. While this model has connected computing devices for decades and will continue to support today IoT networks, it will not be able to respond to the growing needs of the huge IoT ecosystems of tomorrow.
Blockchain for Power Utilities: A View on Capabilities and AdoptionCognizant
Blockchain networks promise to improve process efficiencies, reduce IT costs and elevate trust across the value chain for utilities that pilot new business models pivoting around shared infrastructure and collaborative ecosystems.
Second line of defense for cybersecurity : BlockchainAhmed Banafa
With the fact that cybercrime and cyber security attacks hardly seem to be out of the news these days and the threat is growing globally.
Nobody would appear immune to malicious and offensive acts targeting computer networks, infrastructures and personal computer devices.
Firms clearly must invest to stay resilient.
Gauging the exact size of cybercrime and putting a precise US dollar value on it is nonetheless tricky.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

7. Blockchain Overview
• Public Ledger consisting of completed blocks
• Stored as a distributed database on a peer to peer network
• Ledger stores transactions between participants identified by their public keys
• Uses hashing extensively.
8. Blockchain (Graph)Components
Peer to Peer Network Ledger Transactions Merkle Trees
The p2p network can be
represented as a graph
where nodes refer to
computers and the links
indicate network
connections.
The network will evolve over
time so an additional time
node can show how the
graph evolves over time
Each node in the p2p
network has a closed ledger
as well as a set of
transactions that are yet to
make into the ledger.
Adding time nodes to the
graph can help us track the
evolution of the ledgers over
time.
The ledger itself has
transactions and the
transactions can be
represented as a graph
where the nodes represent
the public key identities
Merkle trees are used to
determine if a particular
digital asset has changed and
can be represented as a tree
of hash pointers.
Merkle trees evolve over time
and the evolution over time
can be captured efficiently in
a graph.
9. P2P Graph
Layer 1 – Network of Nodes
Distributed ledger stored on a network of nodes with each node having a copy of the distributed ledger.
Time – T1 Time – T2 Time – T3 Analytics
• Nodes most frequent
• Size of the network
• Speed at which the links are established
• Network Growth rate
Applications
• Stress testing block chain applications
• Determining network latencies
• Security and intrusion testing
10. Ledger Graph
Layer 2 – Network of Ledger states
Each node will have a closed ledger with the chained blocks and an open ledger of transactions that have not
made it into the block.

11. Transaction Graph
Layer 3 – Transaction Graph
When we look within the ledger, we see a set of accounts/public keys and transactions that occur between
these accounts

Temporal Graph of the Merkle Tree
SimRank can be used to measure the similarity between Graphs efficiently and we will see that the differences in t2 and t3 are
coming from changes to the leaf node H2.
