New #CBECI update! 🚨

Among others, new mining map data covering the period from Sep 2021 to Jan 2022 included confirms the rise of the USA as the world's dominant mining hub, now extending its lead to 37.84% of total hashrate amidst the global recovery.

ccaf.io/cbeci/index But the most notable finding has been the resurgence of China as a major mining hub which – despite the government ban in June 2021 – is reported to host 21.11% of the world's total hashrate.

This seems to empirically confirm what industry insiders have suggested for a while:

Centralisation naturally emerges when efficiency gains are valued higher than corresponding losses in the distribution of power. This seems to be a natural law:
growing costs — financial and non-pecuniary — of a decentralised system are addressed by emergent centralisation, up to a point where the system becomes dysfunctional with respect to its initial purpose, triggering a new wave of decentralisation.

New #CBECI mining map update!

Following the government-mandated crackdown on the Chinese mining industry in June 2021, the US now emerges as the leading #Bitcoin mining centre with ± 35% of total hashrate as of August 2021. Kazakhstan (18%) and the Russian Federation (11%) are following, thereby confirming the trajectory identified in our previous update showing that those three countries had already gained market share prior to the Chinese crackdown.

Looking forward to Matthew Mežinskis‘s presentation on Bitcoin as base money.

If you don‘t know his excellent podcast show @crypto_voices (shout out to co-host @fernandoulrich as well!), make sure to give it a listen.

#bh2019 First, some terminology: there are many names + buzzwords for base money, but they all mean the same: the monetary base.

1) I'm delighted to announce the launch of the Cambridge Bitcoin Electricity Consumption Index (CBECI), a live model that tracks the estimated annual electricity usage of the Bitcoin network in real time.

cbeci.org 2) The CBECI is a pilot project created and maintained by the @CambridgeAltFin in response to growing concerns over the sustainability and environmental impact of Bitcoin mining.

This is the best analysis of Bitcoin's total electricity consumption that I've seen to date. As with any model, some assumptions are debatable, but overall this is some thorough work from Munich.

cell.com/joule/fulltext… I should specify that this applies to the first part of the paper - estimating Bitcoin's total electricity consumption.

We @CambridgeAltFin are currently working on a real-time electricity consumption index based on a similar methodology that we'll launch in a few weeks.

1/ After some quiet and restful Christmas days (I hope everyone had a wonderful break 🎅🎄), here comes Part 2 of my mini series highlighting the key findings of @CambridgeAltFin's new cryptoasset report.

Below is Part 1.
2/ Today we'll have a look at ... users (see Section 2)!

Much has been written about and argued over the number of people using cryptoassets, but little consensus has been achieved so far.

Why?

1/ Today, I'd like to have a look at Section 1 of @CambridgeAltFin's recently published 2nd Global Cryptoasset Benchmarking Study, which covers the cryptoasset industry structure. 2/ What do we mean by cryptoasset industry? While there are many additional service providers (e.g. data, ICOs, analytics/screening, etc.), we focus exclusively on four key industry segments in the context of this study:

- Mining
- Storage
- Exchange
- Payments

1/ Let's get to the core of the report today; namely the conceptual framework that breaks down a #DLT system into distinct pieces in order to better understand the relationships between its elements.

Full report: jbs.cam.ac.uk/faculty-resear…

Alternative link: papers.ssrn.com/sol3/papers.cf… 2/ Speaking of elements: the framework consists of three types: layers, components, and processes.

Each layer is composed of a set of components, and each component comprises a set of processes.

In total, we identify 3 layers, 7 components, and 18 processes.

1/ Today, I'd like to share some of the highlights in Section 2 of our new report on #DLT systems (available here: papers.ssrn.com/sol3/papers.cf…).

We will provide a formal definition of a DLT system and explain some of the key concepts. 2/ Before diving into the key concepts, it is important to understand that unlike 'traditional' databases, DLT systems are designed to operate in an adversarial environment.
