The dialogue encapsulates the profound impact of blockchain on transactional efficiency, trust-building, and future digital economies, setting the stage for continued exploration and innovation in this dynamic field.

Key Takeaways

  • Blockchain is a distributed ledger technology that allows peer-to-peer transactions without a central authority. It uses cryptographic hashing to ensure data integrity.
  • Blockchain has the potential to simplify transactions, reduce errors, and enable near real-time settlement. It could be as transformative as the internet protocol.
  • Paul got involved with blockchain in 2014-2015 when enterprises were starting to explore it. He saw limitations in early solutions which led to developing Tapestry.
  • There are opportunities to use blockchain to track what data AI bots have absorbed, creating an auditable record. AI could also potentially help drive what gets recorded on a blockchain.
  • Tapestry is a configurable, scalable blockchain solution focused on accounting to enable real-time transactions. It is industry-agnostic and can be used for supply chain, healthcare, voting, and more.

Key Quotes

  • [00:03:10] “So there’s a mathematical way to give your own ledger so that you can trust other people based on what you see, not what they present to you. And then there’s a method of agreeing it across the ledger. And so this allows, rather than you transacting through central authorities, what bitcoin really showed the world was you could transact peer-to-peer, or b-to-b, without that central authority, which then means you can settle in hours, minutes, or not seconds.”
  • [00:06:15] “The […] origination of what became Tapestry X was going back to the basics and saying, okay, let’s take the blockchain concepts, but design a distributed ledger that meets the requirements, configurability, scalability, high capacity, real time with accounting and interoperability.”
  • [00:08:04] “The Internet protocol made the Internet. No one could imagine Netflix streaming, Amazon, Airbnb, Uber before the Internet existed […] once it’s really implemented at scale and universally, [blockchain is] going to open up ideas and services that we can’t even imagine today.”
  • [00:11:31] “Blockchain is not technological innovation. It’s a process engineering and operational control innovation. And that’s how people need to think about it.”


Throughout his career, Paul Dowding’s goals have been to develop and improve the global financial services industry commercially and operationally while making it intuitively accessible. Combining an engineering background with practical global operational industry experience and academic research, he has been able to affect innovative change collaboratively. Paul focuses on reducing risks and costs while improving the revenue opportunities, quality, accessibility and speed of innovation within the transactional industries via a differentiating approach to Distributed Ledger Technology (DLT), which he devised and helped design. He created TapestryX from an understanding of process engineering and control, encryption techniques and lay-interest in meta-mathematics.

How to Prevent Ransomware Attacks in 2023 with Jason Rebholiz

2023 is a totally different year from 2022 when it comes to ransom attacks. Based on the activities on the dark web associated with ransom actors, the numbers are going up. Last year, Russia-Ukraine had the numbers go down, but this year, we have a 102 % increase.

In this episode of the Chattinn Cyber podcast, we have the pleasure of hosting Jason Rebholiz. He is the chief information security officer at Convus Insurance and owns a YouTube Channel called Teach Me Cyber. Jason’s passion for data security is peerless, and his knowledge of the industry is something we should all want to hear. His career started at Mandiant, where he tried different things and came to learn his passion was in data security.

Jason and Marc Schein have an in-depth conversation on Ransomware and data security. Jason brings us up to speed with the current ransomware trends in 2023, the groups that are giving data security experts sleepless nights, the effects of AI on data security, and how organizations can keep their data safe.

The Rise Of AI And AI Cybersecurity: How To Future-Proof The Technology of Tomorrow With Vickram Kooblall

In this episode of CHATTINN CYBER, Marc Schein interviews Vickram Kooblall, CIO and CISO at Scahill Law Group. Vickram is in charge of managing the firm’s operations and directing its technology infrastructure. He investigates and analyzes the firm’s digital transformation and cybersecurity resilience initiatives.

Vickram tells us about his upbringing and what led him to a career in cybersecurity. He reveals that the internet was never designed with security in mind, but as it grew, we realized how important it is to manage, secure, and protect data.

Vickram also describes how artificial intelligence has become the digital transformation means of law firms and many other organizations. AI and ML have greatly aided attorneys in many areas, including contract management, document management, due diligence, legal research, behavioral prediction, and so on, allowing them to become better litigators. According to Vickram, law firms deal with sensitive data daily, so data security is critical. He also shared some basic hygiene tips, like, using a strong password and multi-factor authentication.

Internal and external threats are treated equally by law firms. Internal threats are prevented/curbed with utmost employee care, especially during times like the great resignation or big quit, because data is the most important threat then. To ensure data security, many organizations today use zero trust. Encryption is also critical.

Towards the close of the episode, Vikram emphasizes the importance of focusing on AI security because of the numerous native adversarial attacks specific to AI. So, it is important that organizations using data and developing an AI model must also ensure its security.

“Well, certainly in terms of zero trust is becoming, you know, one of those big, you know, big things that we’re seeing organizations do more and more, we are certainly seeing user rights and access management, being something that is looked at very closely and monitored, you know, who should have access to what and when. Also, I think the timing is very important when you’re working on a large case or a particular matter. Those individuals that don’t need access should not have access to those specific cases. During that time. And, you know, it’s going to come back to encryption.”

“You know, in terms of some basic hygiene, one of the biggest things it comes back to is also employee training. That has been one of my focuses, you know, in the last two years ensuring that the employees themselves are very well versed and understand threats that come their way. You know, in terms of strong passwords, that’s been some of the basic hygiene that every organization should implement, and more so many law firms. I have seen at least, maybe once or twice during a week of some law firm email being compromised due to exactly that not having a strong password, we have multi-factor authentication, which is certainly a must-have for any organization, especially, you know, law firms in this space..”

“I think, AI has become the digital transformation that we’ve been looking for. Look, law firms are very slow in adopting new technology and trying to, you know, get a, you know, trying to, it’s always been such a labor-intensive type of practice.”
