In a previous essay, I examined the unlikelihood of a Bitcoin chain split. At the time, hashrate signaling for larger blocks was increasing daily and the prospect of a miner supermajority hard fork appeared likely.
A virtual currency called Ether has been growing alongside Bitcoin in the last year to $35 billion, compared with Bitcoin’s $43 billion.

Cryptogeld vormt een risicovolle belegging, stelde de Autoriteit Financiële Markten (AFM) eerder deze week. De toezichthouder trekt zelfs parallellen met de internetzeepbel van de late jaren negentig. Zijn er werkelijk zoveel risico’s verbonden aan de bitcoin en ethereum?
UASF: User Activated Soft Fork. Developers add a mandatory rule set to change the node’ software, invalidating certain kinds of previously valid blocks after a flag day. This method requires no mining majority to support or activate a chain-split. The UASF proposal intends to make a 51% attack against the blockchain that has the majority […]
About a dozen rain-soaked people were crammed between the revolving doors and security barriers in the lobby of New York University’s Stern School of Business as torrents pelted down outside. All desperately wanted in to the hottest ticket in town, one that promised to make some of them overnight millionaires, if not billionaires. Among them […]
The total market cap for all cryptocurrencies just surpassed $100 billion. The vast majority of these gains have come in just the last few months — on April 1st the total market cap was just over $25 billion — representing a 300 percent increase in value in just over 60 days.
Bitcoin dominates over other digital currencies today, but the data suggests its market share will drop significantly in the next few years.
The best part of the Silbert Accord is that it was negotiated between the relevant parties: the producers of block space (miners) and the consumers of block space (Bitcoin businesses on behalf of their users). Bitcoin has a tendency of annihilating gate keepers and this meeting was a step towards the disintermediation of another group […]
What is Artificial Intelligence ?
Artificial Intelligence is commonly understood as the capacity for a machine or a system to mimic a human-like intelligence through cognitive processes like “learning” and “problem solving”. In the field of computing, the technologies closest to this paradigm are machine learning and deep learning. However, more generally, AI represents the ability […]
Bitcoin was once (and, to some extent, still is) tainted by its association with illicit activity. But as a number of criminals have found out, transactions in Bitcoin can be tracked. So when Zcash, a so-called privacy coin, launched last October, it raised questions about who would want to use such a currency that had the […]
I was yanked down the rabbit hole hard and fast when I first caught the Bitcoin Bug in late 2013. Before I even knew what a “blockchain” was I had founded what is now known as the Blockchain Education Network (then called the College Cryptocurrency Network), and was voraciously trading “altcoins.”
A subsidiary of RWE, one of Germany’s biggest energy and gas provider with 30 million customers and billions of revenue, has launched 100s of electronic vehicles (EV) charging stations all over Germany, connected to ethereum’s public blockchain.
Let’s talk about ownership. What does it mean when you own something? How do you start owning something?
At the foundation of the superstructure of ownership lies the right to possess — to have exclusive physical control of a thing. Owning a physical book, for example, is pretty straightforward: after you purchase it or get it as […]
I have been recently researching Gnosis ahead of the announced auction on the 24th of April. One of the frequent questions that people ask is “How does Gnosis compare to Augur”? I have not found a good impartial comparison, therefore I am writing this.
This is by no means complete or finished overview. When I […]
2017 looks to be shaping up as a watershed year for blockchain-driven central bank digital currencies with China reportedly moving closer to becoming the first major economy in the world to issue its own virtual currency and several other countries including Sweden and South Africa very seriously looking to do the same.
According to a report […]
THE MEANING OF DECENTRALIZATION
“Decentralization” is one of the words that is used in the cryptoeconomics space the most frequently, and is often even viewed as a blockchain’s entire raison d’être, but it is also one of the words that is perhaps defined the most poorly. Thousands of hours of research, and billions of dollars of […]
Tech people love cool new things, and when we talk about Ethereum we hardly ever talk about it as a way of doing things Bitcoin could already do. But the experience of using Bitcoin to pay for things is getting increasingly painful, and it’s time has come to look at how Ethereum could help.
HOW ETHEREUM COULD SHARD THE WEB
Given the state of our 25-year old web and all the problems inherited from legacy 1970’s systems design, we should pause and take inventory of those components which are fundamentally broken and would offer a substantial return on development investment. Intersecting this concern with security, privacy, and censorship resistance, […]
SAN FRANCISCO — Microsoft, JPMorgan Chase and other corporate giants are joining forces to create a new kind of computing system based on the virtual currency network Ethereum.
Some 30 companies are set to announce on Tuesday the formation of the Enterprise Ethereum Alliance, which will create a standard version of the Ethereum software that […]
IS ETHEREUM THE NEW BITCOIN?
Why is Ethereum sudden rise?
During the last month, Ether, or the digital asset that fuels the whole Ethereum blockchain, has grown more than 300%, reaching its all time high of about $60 a few days ago.
At present time, Ether has a value of $50.59 with a market capitalization of $4,469,204,016, […]
TWO THEORIES OF BITCOIN
There are two primary schools of thought on what makes Bitcoin’s properties dependable, and thus what makes Bitcoin a suitable sound money. Which of these theories one believes, whether implicitly or explicitly, will inform one’s assessment of the best approach to making changes or upgrades to Bitcoin. An exploration of these two […]
STATE OF DIGITAL ASSET MANAGEMENT PLATFORMS
Last week Melonport had one of the fastest crowd sales to date. In an Ethereum based crowd sale, they raised 227,000 eth in 2 minutes and 50 seconds. Together with ICONOMI’s ICO, also one of the most successful crowdfunds ever I think it’s safe to say the interest and expectations […]

Distribution of 5743 full nodes obtained from bitnodes.21.co/ (Jan 9th, 2017)
The Bitcoin network is similar to a living organism. It continuously undergoes rapid changes in terms of distribution, size, and quality of its components. Its evolution impacts the security and the performance of the whole system.
De Blockchain kan onder meer vluchtelingen, zzp’ers en overheden helpen, maar staat ook nog in de kinderschoenen. “Het is pionieren.”
Wie zicht verdiept in de technologie Blockchain leest aan de ene kant de ronkende artikelen die vertellen dat deze nieuwe technologie vergelijkbaar is met die van het internet: ontwrichtend en revolutionair. En aan de andere kant de […]
New details have emerged about a soon-to-be-launched initiative focused on enterprise uses of the ethereum protocol.

According to sources, participating firms include JP Morgan, CME Group, BNY Mellon, Banco Santander, Microsoft, Red Hat, Cisco, Wipro and British Petroleum, among […]
Van 10 tot en met 12 februari vindt de grootste fysieke blockchain hackathon ter wereld plaats in de Big Building in Groningen. Een weekend lang werken meer dan 45 teams aan nieuwe en innovatieve manieren om de maatschappij te verbeteren met behulp van op blockchain gebaseerde oplossingen.
Maar wat is blockchain nu eigenlijk? En wat maakt […]
A DEFINITION OF “BITCOIN”
Engineers are great at not seeing the forest for the trees. They get stuck on details and lose track of the bigger picture.
I’ve seen it most often (and have been guilty myself) when they’re optimizing something to make it faster. They’ll start out OK– “it is taking eleven seconds to agitate […]
HERDEFINIËRING VAN CONTROL – BLOCKCHAIN
Blockchain is een nieuwe technologie die helpt bij het opbouwen van vertrouwen en heeft daarmee een zeer betekenisvolle impact op de samenleving. Blockchain zal de wereld en daarmee de control en de verantwoording blijvend veranderen. Blockchain is een digitale handdruk en wordt gezien als de grootste technologische innovatie sinds het […]
THE EXCESSIVE-BLOCK GATE: HOW A BITCOIN UNLIMITED NODE DEALS WITH “LARGE” BLOCKS
Bitcoin Unlimited’s consensus layer is concerned with preserving the money property of Bitcoin. Blocks that are potentially problematic to accept for technical reasons are dealt with in a different layer where network consensus is not critical. This article describes how Bitcoin Unlimited’s excessive-block logic works […]
ON INFLATION, TRANSACTION FEES AND CRYPTOCURRENCY MONETARY POLICY
The primary expense that must be paid by a blockchain is that of security. The blockchain must pay miners or validators to economically participate in its consensus protocol, whether proof of work or proof of stake, and this inevitably incurs some cost. There are two ways to […]
As the block size debate has raged on I’ve noticed more and more bitcoiners (usually on the small block side), argue that Bitcoin should first and foremost be a store of value with all other use cases being secondary at best. In this view, being able to use Bitcoin as money ― that is, exchanging […]
A PROOF OF STAKE DESIGN PHILOSOPHY
Systems like Ethereum (and Bitcoin, and NXT, and Bitshares, etc) are a fundamentally new class of cryptoeconomic organisms — decentralized, jurisdictionless entities that exist entirely in cyberspace, maintained by a combination of cryptography, economics and social consensus. They are kind of like BitTorrent, but they are also not like BitTorrent, as BitTorrent […]
Herein lies 17 decentralized technology predictions for 2017. Thank you to all of my colleagues for my continued education this year and feedback in writing this piece. Please take these predictions with a grain of holiday salt, in other words, not meant to be construed as professional advice. […]
Amid global economic instability and financial crisis, investors are becoming increasingly aware of Bitcoin and its advantages over traditional forms of assets and money. Although many investors remain wary of Bitcoin’s fluctuating price, there are five major aspects of Bitcoin which every investor must know about.
DE BITCOIN KRUIPT WAAR GEWOON GELD NIET GAAN KAN
Nu steeds meer maatregelen worden getroffen die contant betalen belemmeren, biedt de bitcoin veelal een uitweg. De handel in de virtuele munt blijft maar toenemen en de waarde van de munt verdubbelde zelfs in één jaar tijd. Hoe werkt de bitcoin eigenlijk en wat wordt er […]
SEGREGATED WITNESS: A FORK TOO FAR
This paper first examines Segregated Witness (SW), then demonstrates how it can only fail to realize its designed purpose, how it encumbers Bitcoin with irreversible technical debt, and how it threatens the fungibility of the currency. After reading this, it should be clear to miners why they should: […]
Het moet de belangrijkste stap worden naar een volledig gedigitaliseerde samenleving: blockchaintechnologie. Op tal van plaatsen wordt ermee geëxperimenteerd, maar de talrijke toepassingen ervan gaan ons voorstellingsvermogen nog vaak te boven. Hoe lang blijft dat nog zo?
Ethereum Learns To Use A Fork (And Other Signs Baby Is Growing Up)
We’ve been hearing some concern about Ethereum’s latest hard fork and how it affects the platform, so we thought we might explain what happened and attempt to clear up any misinformation.
Basically we think any consternation about recent (intentional and unintentional) forks […]
Blockchain begint zo langzamerhand de hype te ontgroeien. De technologie wordt op steeds meer plekken succesvol toegepast. Dat gaat gevolgen hebben voor veel sectoren. Maar de kennis van zaken is nog gering. Het speeltje van echte nerds werd het favoriete speeltje van beleggers, al ging dat niet vanzelf. De waarde van bitcoin steeg eind november […]
CORE SEGWIT – THINKING OF UPGRADING? YOU NEED TO READ THIS!
So, voting on core’s implementation of Segwit is now enabled, and all 3 of the miners that support core have already cast their vote (2 pools and 1 cloud mining MLM), totalling about 23% of the network. Adoption seems to have stalled (as of 4Dec16) as the […]
At the end of May of 2013, it was revealed that a new bill for the regulation of the banking and financial sector was, to all intents and purposes, drafted by Citigroup. This is only the latest in a long list of what can only be called legalized corruption at the highest levels of American […]
What is sharding?
Currently, all blockchain protocols rely on a model where all nodes store all state (account balances, contract code and storage, etc) and process all transactions. This provides a large amount of security, but greatly limits blockchains’ scalability: a blockchain cannot process more transactions than a single node in the network. […]
THE EXCESSIVE-BLOCK GATE: HOW A BITCOIN UNLIMITED NODE DEALS WITH “LARGE” BLOCKS
Bitcoin Unlimited’s consensus layer is concerned with preserving the money property of Bitcoin. Blocks that are potentially problematic to accept for technical reasons are dealt with in a different layer where network consensus is not critical. This article describes how Bitcoin Unlimited’s excessive-block logic […]
A (BRIEF AND INCOMPLETE) HISTORY OF CENSORSHIP IN /R/BITCOIN
Please do not use the censored /r/bitcoin or Bitcointalk. Use /r/btcinstead.
The free and open discussions on this forum help individuals and the Bitcoin community achieve Truth. Everyone has some wisdom or knowledge to contribute to a discussion, and everyone who reads the discussion and gains that […]
Blockchain en auteursrecht, gaat dot.blockchain (.BC) de muziekindustrie en copyright beheer veranderen?
Sinds december 2014 zijn er een aantal artikelen verschenen over de mogelijkheden van het gebruik van blockchain technologie in de muziekindustrie, in het bijzonder betreffende het beheren van auteursrechten. Eerst zal ik kort bespreken wat de blockchain is, daarna zal ik het dot.blockchain initiatief van Benji Rogers bespreken. […]
BANKEN VERDWIJNEN DOOR OPKOMST BLOCKCHAIN
Door blockchain verdwijnt de helft van de banken, komen activistische aandeelhouders in zicht vanaf de eerste transactie en zullen centrale tegenpartijen voor het afhandelen van transacties overbodig worden. De versleuteltechniek heeft de potentie de financiële industrie op zijn kop te zetten.
Dat stelt David Yermack, hoogleraar aan de New Yorkse Stern […]
Heeft bitcoin de toekomst? Nee, maar de achterliggende blockchain-technologie wel. Hoe blockchain bij Bitcoin werkt.
In potentie heeft blockchain de capaciteit in zich om de wereld te veranderen op een schaal die te vergelijken is met de komst van internet. Geen wonder dat iedereen wil weten wat blockchain is. Vorige week legde ik de principes en werking van blockchain uit aan verzekeraars. Eerder mocht ik spreken voor accountants, bankiers, IT-auditors, […]
Digital currency may be the most effective way the world has ever seen to increase economic freedom. If this happens, the implications are profound. It could lift many countries out of poverty, improve the lives of billions of people, and accelerate the pace of innovation in the world.
This is why I co-founded a digital […]
The Bitcoin network’s creation of normal blocks and single (coinbase-only) transaction blocks is analyzed using multiple empirical approaches. A maximum Bitcoin network transaction commitment throughput of 60KB/sec is derived. The significant role of single-transaction blocks in limiting this throughput is then shown. The miner revenue equation in an unlimited-block environment is derived, and it is […]
