The big-daddy of the alts - a claim contested by thousands of self-professed Ethereum-Killers who unfortunately got rekt by crypto-volatility.
Token Curated Registries (TCRs) are a building block of decentralized applications based on fungible tokens (FTs) and digital scarcity. They are fast becoming one of the hottest “Token Building Blocks” for decentralized blockchain applications. The use cases for TCRs are far reaching, everything from a simple whitelist to full blown decentralized governance. In this post I discuss some design patterns for TCRs and potential use cases. I am not purporting to know the Schelling point parameters, nor have I built these TCRs. This is for design thinking and use case exploration to spur innovation in the community.
This is PART-4 of The Product Manager’s guide to the Blockchain series! If you somehow landed on my publication for the first time, Welcome! I recommend you start from part 1, and then read part 2 and part3 before reading this post. However If you are the explorer type, read on!
Mining is a great way to enter the cryptocurrency ecosystem. However, Bitcoin/Litecoin is almost impossible to mine for the average user. It requires expensive equipment called ASICs that are made by a controversial, centralized company called Bitmain. These ASIC chips consume high amounts of electricity, and ASIC mining farms often use cheap & ecologically-destructive coal power. These centralized mining cartels mint the vast majority of new Bitcoin, and are responsible for contentious forks of Bitcoin in order to maintain a monopoly of the network.
As the popularity of Bitcoin and other cryptocurrencies is increasing either due to astronomical price increase of Bitcoin over past few days or so many public figures making pro comments and few against it, this is making more and more people to learn and invest in Bitcoin.
GAS PRICE PSA (2017–08–23): The median gas price at the time of writing this article was 28 Gwei, and continues to be in the realm of 20 Gwei. This is far greater than the typical average and safe-low found on EthGasStation (4 and 0.5 Gwei respectively). The median is so high because of bad gas-price defaults found in many wallets. I highly recommend using EthGasStation’s average gas-price or lower in order to not pay high fees and to help drive down the market rate for gas-price.
UPDATE: I have created a repo for you to play around with that showcases most of the stuff covered in this article.
I am the Blockchain! I am invincible because I replicate myself on multiple computers. Yea like the Ultron. You cannot corrupt me. Though Bitcoin and Ethereum were my first applications. My true power is yet to be unleashed.
The sale disappeared as fast as it arrived so it seems to be a perfect time to learn about another promising coin in preparation for next sale. As mentioned in the first part of series (which can be found there), my next pick is a coin based on the Ethereum platform. Lets see what this particular currency is about and what the team is trying to deliver.
One of the most unique features of blockchain is its quality of acting as a decentralized which is shared between all the parties of the network thus, eliminating the involvement of middlemen or third-party intermediaries. This feature is particularly useful because it saves you from the chances of any process conflict and saves time too. Though Blockchains have their own set of issues that are yet to be resolved, they offer faster, cheaper and more efficient options as compared to the traditional systems. Due to this, even the banks and governmental organizations are turning to blockchains these days.
If you’re ever stranded on a deserted island, knowing how to run the process of decentralized consensus — or in other words, operate a very simple blockchain by hand — can prove to be very useful. All you need is some fellow survivors, this post, a pen and a few pieces of paper.
An easy way to spot a startup that won’t provide return on investment is to look for the words “blockchain” or “decentralized” on their landing pages.
By now everyone has heard of CryptoKitties, a cute game that went viral to the point of overloading the whole Ethereum network. This is the inside story behind how we made $107K investing in CryptoKitties and briefly set the record for the largest sale ever (currently second-largest). Later, we made ~$8K running an automated arbitrage bot. While playing the speculation game at the height of the mania was exciting, the bot was fairly technically involved and will be interesting to people who want to learn blockchain engineering in general.
With the rise of Ethereum and Initial Coin Offerings (ICO’s), especially ERC20 tokens, people unfamiliar with Ethereum or other cryptocurrencies like BitCoin are becoming interested in the technology. Unfortunately, getting started with Ethereum and participating in ICO’s is not simple.
I have been into with various Crypto Lending platforms for awhile now and thought i’d share some of my thoughts and experiences on each. Some of these are Decentralised Finance (DeFi) platforms while others are not.
It’s 2017 and the cryptocurrency party is in full swing with both Bitcoin and Ethereum up 400% and 5000% at one point respectively. Banks took a huge U-turn and stopped closing down the accounts of so-called “suspicious” Bitcoin traders in favor of joining the Ethereum Enterprise Alliance. Even my largely reclusive Asian tiger mom has heard of the 比特币. Yet amidst this bulging backdrop (or bubble depending on your point of view), there are surprisingly very few direct, end-to-end resources for the retail investor to take part in this speculation smorgasbord.
Update: Based on the reception to this article, I expanded on some of the ideas explored here and comments I received in response to them in a video embedded at the bottom. Take a look and share your opinion.
The proof of stake system is attracting a lot of attention these days, with Ethereum switching over to this system from the proof of work system. Proof of stake is an alternative process for transaction verification on a blockchain. It is increasing in popularity and being adopted by several cryptocurrencies. To understand proof of stake, it is important to have a basic idea of proof of work. As of this writing, the proof of work method is used by Bitcoin, Ethereum and most other major cryptocurrencies.
Do you remember when stablecoins were still just for hedging risks? In the crypto industry, just about anything can become a source of profit – including stablecoins. But which of the USD-pegged coins should you buy to maximize your earnings?
Knowing how to buy and sell cryptocurrency on a crypto exchange is not enough, you need to have a secure crypto wallet where will store your assets. Just like walking holding all your hard earned money on your hands can be risky, leaving your digital tokens on the exchange can be a big risk. If the exchange gets hacked, you coins could disappear into thin air.
23. How one hacker stole thousands of dollars worth of cryptocurrency with a classic code injection…
Bitcoin, Cryptocurrency, Ethereum — you must have heard about these buzzwords. And maybe the stories of people making a quick fortune out of it, and why not — look at the market capitalization of so-called ‘Cryptocurrencies’ and how it has grown in the last year. Blockchain is the idea which drives them all.
Today, while using a Ledger Nano S — I was shocked to see this scary message after I left my ledger nano s for few minutes while a transaction was confirming. The message was scrolling horizontally saying “Vires in Numeris”
Unless you’re hiding under the rock, I am sure you’d have heard of Bitcoins and Blockchain. After all, they are the trending and media’s favorite topics these days — the buzzwords of the year. Even the people who’ve never mined a cryptocurrency or understand how it works, are talking about it. I have more non-technical friends than technical ones. They have been bugging me for weeks to explain this new buzzword to them. I guess there are thousands out there who feel the same. And when that happens, there comes a time to write something to which everyone can point the other lost souls to — that’s the purpose of this post — written in plain english that any regular internet user understands.
For many people, buying large amounts of Bitcoin is not a financially-viable investment strategy. But the good news is that there are now more alternatives than ever that make it easy for people to earn bitcoin.
When someone sends bitcoin to you, they send the bitcoin to your address. If you want to spend any of the bitcoin that is sent to your address, you create a transaction and specify where your bitcoin ought to go. Such a transaction may look like:

So you’ve taken the red pill, and now you’re either looking to invest, or have started investing into cryptocurrencies already. With the overall crypto market growing over $100 billion in value in just 2 weeks (as of this writing), the space is heating up and it’s entering mainstream adoption.
If you are reading this post, you perhaps already know what a blockchain is. If not, here is an interesting video by the World Economic Forum on what the blockchain is today and could be in the very very near future.
40. Millions of Dollars Are Waiting to Flood Into Cryptocurrencies But They’re Stuck on the Sidelines …
It’s the “WHALES” aka people with at LEAST several million dollars worth of cryptos in their possession, in “old school” financial terms these are the people known as “High Net Worth Individuals” (HNWI).
We took a glance at some of the hottest ICOs of the quarter as reviewed by the likes of Ian Balina, OhHeyMatty, IcoBench, IcoDrops and so on and put them through our usual process and then summarised the results into the complete guide you see below.
The first Bitcoin paper was first released in 2008. My excitement about the potential of blockchain technology has been building ever since.
Decentralized digital currency, once just a far-fetched goal, is finally making inroads into the mainstream. While that’s exciting on its own merit, I’m personally most excited about the potential for decentralized applications. Financial exchanges, prediction markets, and asset management platforms all carry enormous potential.
The trustless systems supporting them are no less intriguing; identity verification systems, smart property, censorship resistant social platforms, and autonomous structures and governance models like DAOs. The most disruptive use cases probably haven’t even been dreamt up yet.
But this dream still remains a dream for the foreseeable future — while a few early enthusiasts and entrepreneurs are experimenting with building such applications, there’s still a big missing piece that prevents us from seeing these applications come to fruition: scalability. Blockchains, as it stands today, are limited in their ability to scale.
That’s not to say that this will be the case forever, but it’s definitely true today. In fact, I’d argue it’s one of the biggest technological barriers we face with blockchain technology today. It’s quickly become a very active area of research among researchers in the community and cryptocurrency in general.
This post is a deep-dive into programmatically trading on the Ethereum / Bancor exchange and exploiting a game-theoretic security flaw in Bancor, a high-profile smart contract on the Ethereum blockchain. The full code can be found at https://github.com/bogatyy/bancor. We collaborated with the Bancor team to make sure the current exploit is protected against, although for a little while there would still be a chance to make some beer money for educational purposes.
The real opportunity in crypto is taking existing liquid assets trapped on local expensive exchanges and making them global, real-time, 24/7. Not just existing assets but over time every asset, every home, every private equity and venture fund… everything. That’s the opportunity Polymath is addressing.
61. Yes, this kid really just deleted $300 MILLION by messing around with Ethereum’s smart contracts.
Last year, The DAO, a decentralized ‘autonomous’ investment fund, got hacked for $50 million. In July, a hacker was able to steal $31M of Ether by exploting a bug found in Parity’s wallets. Today, we have the worst hack yet, only this time, the stakes are even bigger and it is all just one big fuck-up.
