Smart Ledger Cities: How Do We Rate And Rank Them?



Wednesday 27 June, 2018

Professor Michael Mainelli
Z/Yen Group



Z/Yen held a workshop for a select audience of around 15-20 people, which was preceded by networking and refreshments. 

Smart Ledgers are the ‘next big thing’ in technology. They’re based on a combination of mutual distributed ledgers (MDLs, aka blockchain: multi-organisational databases with a super audit trail, used since 2009 in cryptocurrencies) with embedded programming and sensing, thus permitting semi-intelligent, autonomous transactions. Smart Ledgers are touted as a technology for fair play in a globalised world.

The workshop investigated if we can rate and rank Cities (centres) based on the below criteria (“IDLP” acronym), and if so, what are the instrumental factors?:

  • I = Identity: How much is happening generally in a site, its viability
  • D = Documentation & Agreements: How standards-type agencies are agreeing the nuts and bolts
  • L = Legal & Regulatory: What are the mechanisms for enforcing contracts
  • P = Payments, Currencies: How are SL payments used/not used
