### [1. Token Curated Registry (TCR) Design Patterns](https://hackernoon.com/token-curated-registry-tcr-design-patterns-4de6d18efa15)
![](https://hackernoon.com/hn-images/1*ns2zugWzrdeYgO_BQBU9QA.jpeg)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 “<a href="https://blog.oceanprotocol.com/towards-a-hierarchy-of-token-building-blocks-6c8dd7b42341" target="_blank">Token Building Blocks</a>” for decentralized <a href="https://hackernoon.com/tagged/blockchain" target="_blank">blockchain</a> 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 <a href="https://hackernoon.com/tagged/design" target="_blank">design</a> 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.

If you somehow landed on my publication for the first time, Welcome!

### [3. Mine for Bitcoin with ANY Computer](https://hackernoon.com/mine-for-bitcoin-with-any-computer-9a30337843e7)
![](https://hackernoon.com/hn-images/1*UssPqElZPSU062FULsRU7w.png)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 &amp; 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.

![](https://hackernoon.com/hn-images/1*VDuM2ka3Ydw1iTIR9aEbFw.png)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.

![](https://hackernoon.com/hn-images/1*q3WWzT8MQIUCB9n-wuj8Cw.jpeg)<strong><em>GAS PRICE PSA</em></strong><em> (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 </em><a href="http://ethgasstation.info/" target="_blank"><em>EthGasStation</em></a><em> (4 and 0.5 Gwei respectively). The median is so high because of bad gas-price defaults found in many wallets. I </em><strong><em>highly recommend</em></strong><em> 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.</em>

![](https://hackernoon.com/hn-images/1*On6VdlhquqNxsQ5yJygSlQ.jpeg)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 <a href="https://medium.com/@mik.umanski/my-cryptocurrency-picks-for-2018-part-1-ethereum-248b4eb64414" target="_blank">there</a>), my next pick is a coin based on the Ethereum platform.

### [11. Everything You Need to Know About Smart Contracts: A Beginner’s Guide](https://hackernoon.com/everything-you-need-to-know-about-smart-contracts-a-beginners-guide-c13cc138378a)
![](https://hackernoon.com/hn-images/1*fXGujEsDSvvvKI-XYpW8RQ.jpeg)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.

![](https://hackernoon.com/hn-images/1*BjR6DEBCmQ4bvWDxr6ynwQ.jpeg)If you’re ever stranded on a deserted island, knowing how to run the process of <em>decentralized consensus</em> — or in other words, operate a very simple <a href="https://hackernoon.com/tagged/blockchain" target="_blank">blockchain</a> by hand — can prove to be very useful.

![](https://hackernoon.com/hn-images/0*nApf9UzfooT9L9B-.)<strong>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.</strong>

Banks took a huge U-turn and stopped closing down the accounts of so-called “suspicious” Bitcoin traders in favor of joining the <a href="https://entethalliance.org/" target="_blank">Ethereum Enterprise Alliance</a>. Even my largely reclusive Asian tiger mom has heard of the <a href="https://www.youtube.com/watch?v=pADgAmNzxek" target="_blank">比特币</a>. 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.

![](https://hackernoon.com/hn-images/1*eybzZVZmAxILAlXEbhaoKw.jpeg)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.

My excitement about the potential of blockchain technology has been building ever since.&nbsp;<br>&nbsp;<br>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.&nbsp;<br>&nbsp;<br>The <em>trustless systems </em>supporting them are no less intriguing; identity verification systems, smart property, <em>censorship resistant </em>social platforms, and <em>autonomous structures and</em> <em>governance models</em> like <a href="https://en.wikipedia.org/wiki/Decentralized_autonomous_organization" target="_blank">DAOs</a>. The most disruptive use cases probably haven’t even been dreamt up yet.&nbsp;<br>&nbsp;<br>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<em>: </em><strong><em>scalability</em></strong><em>. </em><strong>Blockchains, as it stands today, are limited in their ability to scale. </strong><br>&nbsp;<br>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.
