Can we design permissionless distributed ledgers for payment processors without compromising security?
Description
Advocates proclaim that blockchain technology will help financial organizations speed up settlements and ensure the certainty of ownership, while improving transaction transparency. However, there are several technological challenges that continue to hinder the implementation of blockchain with payment processors. Scalability is one of, if not the biggest, issue in this regard.


How do we ensure that extending the scope of blockchain applications won’t negatively affect the speed of operations? Moreover, how we safeguard against security breaches?

Secure distributed ledgers

Designing secure permissionless distributed ledgers for centralized payment processors is challenging. The majority of existing ledgers are unable to scale-out; those that have, significantly compromised security and decentralization.

We invite you to join us in discussing the dilemma of security and scalability, and in examining some of the recently proposed solutions -- specifically OmniLedger. Philipp Jovanovich will be providing insight into the scale-out distributed ledger that is able to preserve long-term security under permissionless operation.

OmniLedger is said to ensure strong correctness and security by using a bias-resistant public randomness protocol combined with an efficient cross-shard commit protocol.
