Outside John Snow Pub, arguably one of the best pubs to visit on a rainy November day in Soho, London, I was having a beer with my dear friend Alex, discussing tech and cryptocurrency like we always do. The thing that struck me the most from the conversation that Alex brought up was the technical challenges of Mars to have its own blockchain due to speed of light delays between Earth and Mars. It took me on a little journey of determining what might a blockchain on Mars look like, what are the challenges brought upon by speed of light and other factors, and how to push forward the efforts of colonizing the Red Planet.

The past few years and especially 2017 have brought cryptocurrency to the mainstream. Everyone and their grandmother can be seen at one point asking around “How can one buy bitcoin?” and “Would you buy Ripple?” among other questions. Every day, someone armed with a badly-edited whitepaper (a paper outlining how the technology works) will raise millions of dollars in Initial Coin Offerings, or ICOs (the cryptocurrency version of a stock market IPO). By now, one can see that, while 99% of the coins will probably fail due to bad planning, overpromised marketing, or because of their scammy nature, there is no doubt that the future of the cryptocurrency market is bright and it has a lot of room for growth.

The race to Mars is on going. SpaceX still is leading the efforts to allow humans for colonization of the Red Planet, most recently with their two simultaneous Falcon Heavy rocket landings.

Fiber-optic cables package everything from financial data to cat videos into light, but when the signal arrives at your local data center, it runs into a silicon bottleneck. Instead of light, computers run on electrons moving through silicon-based chips, which are less efficient than photonics. To break through, scientists have been developing lasers that work on silicon. Researchers now write that the future of silicon-based lasers may be in quantum dots.

India now generates around 1,160.1 billion units of electricity in financial year 2017, up 4.72% from the previous year. The country is behind only China which produced 6,015 terrawatt hours (TWh. 1 TW = 1,000,000 megawatts) and the US (4,327 TWh), and is ahead of Russia, Japan, Germany, and Canada.

Total electricity production stood at 1,003.52 billion units in India between April 2017 and January 2018. “Multiple drivers (like industrial expansion and rising per capita income) are leading to growth in power demand; this is set to continue in the coming years,” said a report by the India Brand Equity Foundation (IBEF), an arm of the Indian government’s ministry of commerce.

Getting your head around cryptocurrencies was hard enough before governments got involved. But now that policy makers around the world are drawing up fresh regulations on everything from exchanges to initial coin offerings, keeping track of what’s legal has become just as daunting as figuring out which newfangled token might turn into the next Bitcoin.

The rules can vary wildly by country, given a lack of global coordination among authorities. And while that may change after finance chiefs discuss digital assets at the Group of 20 meeting in Buenos Aires this week, for the time being there’s a wide range of opinions on how best to regulate the space. Below is a rundown of what major countries are doing now.

Binance, the world’s largest cryptocurrency exchange by traded value, is seeking a fresh start in the Mediterranean.

The company, founded last year in Hong Kong, is planning to open an office in Malta, said founder Zhao Changpeng in an interview from Hong Kong. Binance will soon start a “fiat-to-crypto exchange” on the European island nation, and is close to securing a deal with local banks that can provide access to deposits and withdrawals, he said, without providing a timeframe.

“We are very confident we can announce a banking partnership there soon,” Zhao said. “Malta is very progressive when it comes to crypto and fintech.”

You may have heard of Numerai — the unorthodox hedge fund that crowdsources predictive stock market models from data scientists around the world. It is now seeking more brain power and announced today that it is giving away $1 million worth of cryptocurrency to Kaggle users who sign up. The San Francisco-based hedge fund incentivizes its community members by giving them digital tokens they can stake during tournaments to express confidence in their predictions. The best trading algorithms are then selected based on how they perform on the live market, and their creators are rewarded with more tokens.

Looking at most Wall Street hedge funds’ models, it’s fair to say open, collaborative efforts aren’t at their core. Movies like Wall Street, which portrays a greedy Gordon Gekko, and The Wolf of Wall Street, which highlights the derailing decadence of power and money, paint a rather unflattering picture of egocentric traders and financiers. Numerai founder and CEO Richard Craib is looking to change that.

The 30-year-old South African wants to create a more open and decentralized ecosystem for hedge funds. Rather than restricting access to trading data, Craib encrypts it before sharing it with his global network of data scientists, which effectively prevents them stealing and replicating the trades on their own. They can, however, use the shared information to build predictive models for the hedge fund.

John Oliver is a crossover who bridges the art of a comedian with the reporting and perspective of a liberal political pundit. Even detractors acknowledge that Oliver addresses serious issues with unusual wit and humor.

I never thought Oliver could (or would) tackle the topic of cryptocurrency—at least not with value to the viewer. It is too geeky, and too esoteric. (It also cuts into my mission of evangelism and education). smile

He did, and he sparkles! Feel free to jump past the fluff. The Bitcoin tutorial starts at 3:40. Of course, my friend, Shechter, in Long Island New York will bust a gut over what Oliver says at 9:40. It is not only clear and concise, it is accurate and terribly funny!

Whether you are a Bitcoin newbie or a seasoned blockchain coder, this is the video you have been looking for. This one is durable.

Today, I was asked to answer this question at Quora:

What sets each cryptocurrency apart from the others?

“Cryptocurrency” is a broad term. It refers to payment coins, of course—such as Bitcoin and Litecoin. But, because most tradeable tokens attain an asset value, the word is often used to refer to smart contract devices, such as Ethereum, a host of other blockchain based tokens, functional Internet-of-Things tokens, and even ICOs (Initial Coin Offerings). Since people treat ICOs and IOT tokens as investment instruments even if they are useless as a payment mechanism, they all fall within the realm of a cryptocurrency.

So, before addressing the question, let’s distinguish between Altcoins and ICOs. I assume the question refers to Altcoins, and not ICOs…

ICOs are almost all scams. A very few of these are designed to function in a well-defined IOT role (Internet-of-Things). But, any ICO that you are likely to hear about share one or more traits described here.

But Altcoins are different. These are typically forked from Bitcoin or another established blockchain-backed coin. They are created because developers feel that they have solved one or more of the problems that limit the growth or appeal of Bitcoin. For example, Bitcoin has (or recently had) all these problems or perceived limitations:

  • Transaction Malleability (Recently solved with activation of SegWit)
  • Speed of transaction (Now being addressed by Lightning Network)
  • Cost of transaction (Also addressed by Lightning Network early 2018)
  • Very high electrical demand by miners (Still a major problem)
  • Fairness of and speed of distributed governance process (a big problem)
  • Finding a validation incentive after mining runs out (a long term issue)
  • Deep privacy features. These are inherent to Monero and Zcash. (Bitcoin will soon support onion routing transactions to enhance privacy)
  • Disparate goals of miners, developers, vendors and users (still a problem)
  • Limited Smart Contract mechanism (Ethereum is the current king in this realm, with slick methods of administering and executing contracts. Bitcoin will eventually acquire these features & benefits.
  • Like ICOs (these are almost all scams), some Altcoins (not scams) address specific IOT applications. This is a legitimate and non-payment use of blockchain technology. It represents a promising evolution. It is not yet clear if Bitcoin can eventually adopt these features and function in a non-payment, IOT capacity. The intrinsic, stored value aspect of Bitcoin would make it difficult to use in such applications.

One big problem facing Bitcoin is that the distributed consensus mechanism that makes it a trusted, peer-to-peer mechanism is based on Proof-of-Work (POW). Coupled with a mining incentive that increases dramatically with exchange rate, Bitcoin is—quite simply—untenable. With consumption topping 33 terawatt hours in December 2017, it already consumes more power than some countries. If even 2% of the world’s payment transactions were settled in Bitcoin, the mining would consume more power than is generated throughout the world. This just cannot continue!

Fortunately, developers and armchair inventors have proposed or demonstrated clever POW alternatives to achieve a fair distributed consensus. Some of these use a Proof-of-Stake mechanism, while others add a limited central-authority nexus to facilitate governance and scaling. Some are built on a modified blockchain that weaken several pillars of a true decentralized, p2p network. Of course, researchers are concerned that these systems deteriorate the decentralized nature of Satoshi’s original blockchain.

But, other systems may allow for a fully distributed and democratic trust platform, such as BFT Replication (IBM) or Distributed Objective Consensus, which was proposed by an amateur mathematician.

In reply to the title question, Altcoins are set apart by their claim to address the above problems & limitations, or to add features.

Will an Altcoin Triumph over Bitcoin?

Perhaps, a few altcoins will thrive, due to specific niche advantages; features that Bitcoin chooses not to address, such as deep anonymity or with a novel utilitarian feature that facilitates a specific Internet-of-Things process.

Unfortunately for altcoins, all coins require public trust and transparency. For this reason, they are open source, permissionless, without licensing, without patent protection and with a fully disclosed pre-mining history. And for that reason, Bitcoin is free to steal any clever advantage that works. It’s all up for grabs and no one can be sued.

In effect, each altcoin as a beta test platform for Bitcoin. Now that Bitcoin is finally addressing the problems of scalability and fair/speedy governance, there is little doubt that it will continue to dwarf other coins.
