Paul Dowding, Gartland and Mellina Group, says that current blockchain designs are not able to provide real-time solutions but a solution is technically possible
In one of his famous paradoxes, the ancient Greek philosopher Zeno tells us how Achilles decides to race a tortoise but allows it a head start. When the race begins, Achilles runs to where the tortoise started but finds it has already moved. He then runs to the point where the tortoise moved to, only to again find it slightly ahead. This cycle continues until Achilles finally gives up exhausted, unable to ever overtake.
Current blockchain solutions in the financial services industry have their own logical paradoxes to overcome. A blockchain ledger needs a validation mechanism, yet this introduces capacity constraints and latency, which, like Achilles, means it can never catch up with real-time processing.
While Bitcoin, the original use of blockchain, dealt with simple transfers of ledger-referenced value, Wall Street's full set of interdependent products and lifecycles represent an Olympic pantheon of events.
Additionally, current blockchain solutions require an ever-expanding continuous record in order to access any prior transactions...
