The ILL Bloom session comes to an end! We explored how randomness is generated, how weak random number generators work, and their impact on crypto wallet security. Kudos to @coinspect team for the research behind ILL Bloom & thanks to everyone who joined.

How much control do we really have over our digital identities? At OCCSSG, we explored Self-Sovereign Identity (SSI) and how cryptography can shift identity ownership from centralised providers towards individuals.

The discussion began with three identity models: • Centralised Identity • Federated Identity • Self-Sovereign Identity (SSI) Each represents a different approach to managing identity, trust and control over personal information.

How can two people establish a shared secret over a public channel without ever exchanging the secret itself? This is the problem Diffie-Hellman Key Exchange set out to solve. A fundamental breakthrough in modern cryptography.

The mathematics behind it relies on two ideas: • Modular arithmetic • The Discrete Logarithm Problem Computing modular exponentiation is easy. Reversing it to recover the original exponent is computationally difficult. This asymmetry is central to Diffie-Hellman.
