When is a Blockchain a blockchain? When is a cryptocurrency a cryptocurrency?

on 04 July 2019

After years of collaborating with a group called Libra, that group more recently changed its name – and shortly afterward, it became clear why: a social media giant had bought the name to establish its own cryptocurrency, Libra.

And so back to the question. I have had the honor of working with the International Organization for Standardization (ISO) as a national expert to ISO/TC 307 Blockchain and Distributed Ledger Technologies. That group will establish the ISO standards for that space, including terminology. I also had the honor of working on a commercial effort with Stuart Haber. Stuart is referenced three times in the Bitcoin whitepaper of Satoshi Nakamoto, and the use of cryptographic means to add new blocks of data to an existing chain is his development, commercialized more than a decade before Bitcoin.

The Bitcoin whitepaper, which focused on peer-to-peer payments not requiring a central intermediary – “based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party.” But now many of my colleagues believe that if the cryptographically supported chain of blocks isn’t peer-to-peer/decentralized, it isn’t a blockchain. While Bitcoin introduced decentralization, consensus, incentive mechanisms and other goodies, Stuart’s solution provided public mechanisms for anyone to be able to check the integrity of documents on his chain of blocks.

 How about Libra? Is it a cryptocurrency? Do we use Bitcoin as the model – decentralization, permissionless? Or perhaps Beenz, the haz-beenz one time “currency of the Web”?

Does any of this influence your business, your investing, your financing?

    Where Will Technology Progress Take The Accounting Profession?
    Monday, 29 March 2021

    Ricardo Rodil leads the capital markets advisory services division at Crowe Macro (Brazil).

    Every time I try to understand or analyze a very complex event,  I usually try to reduce the problem to its essential elements – a sort of inverted zoom lens. I know that the devil is in the details, but I need to have some distance from them. So, I formulate extreme hypotheses, thinking about all the possible/plausible results (from 8 thru 8,000, as we say in Brazil). And, of capital importance, I know I need to keep my mind open to all possibilities. Today, I want to share with you where my latest thoughts have led me, about where and how technology is progressing and how that is transforming our lives.

    In a non-random survey of some 915 innovators, developers, business and policy leaders, researchers and activists were asked by Pew Research to consider what life will be like in 2025 in the wake of the outbreak of the global pandemic. Overall they saw life being made worse for many people because of the spread of mis-information and authoritarianism and the fact people will become a lot more reliant on technology, which will serve to widen the economic divide.
