Bitcoin Dominance Drops Near 50% – Boom on the Way? 0

Bitcoin Dominance Drops Near 50% – Boom on the Way?

There’s a buzz in the cryptosphere today. Bitcoin dominance hasn’t been this low since last August. Google trends show that interest in Bitcoin hasn’t been this low since last April. Are we in the quiet before the storm or status quo? Dominance is hovering just above 50%. A result of “alt season,” money rapidly flowing into altcoins and a relatively stagnant Bitcoin price conspire to lower the actual position of Bitcoin. But not by much. Bitcoin’s market capitalization can still fit hundreds of other cryptos within it. This Isn’t 2015 or 2017 – The Market Is Far More Crowded Some

WTF is Cuckoo Cycle PoW algorithm that attract projects like Cortex and Grin? 0

WTF is Cuckoo Cycle PoW algorithm that attract projects like Cortex and Grin?

WTF is Cuckoo Cycle PoW algorithm that attract projects like Grin and Cortex?

In 2017, the cryptocurrency rage reached to the highest point when Bitcoin surged to USD19,783, many speculators and miners started to invest an enormous amount of money into mining hardware and chips hoping to get on the craze. Cryptocurrency mining was originally designed to be doable with general-purpose computers. Yet with the increase in competition to the limited resources, miners have been seeking an effective way to improve their chances.

Application-specific integrated circuit chips, known as ASIC, has taken over the mining market since. ASIC are chips that are designed with a singular purpose. For cryptocurrency mining, these chips are built into specifically designed motherboards and power supplies to efficiently solve a specific algorithm. Each cryptocurrency has its own cryptographic hash algorithm and ASIC hardware are designed to excel at calculating that algorithm, in the case of Bitcoin, ASIC hardware is designed to calculate the SHA-256 hash algorithm.

However, in 2018, the bearish performance in the cryptocurrency market has put them in a difficult situation. Though with better performance comparing the general-purpose computer using GPU or CPU cards, there is a limited room of adjustment for the ASIC hardware. ASIC miners were seeking ways to deal with their machines and spaces they rent for running the mining machines. In contrast, GPU miners can easily adapt to new PoW algorithms and tokens due to better compatibility with different hash algorithms (in the cost of performance). Furthermore, the emerging of Cuckoo Cycle algorithm sheds light on the GPU mining to compete against the ASIC miners.

What is Cuckoo Cycle PoW algorithm?

Cuckoo cycle is one of the most promising ASIC-resistant PoW algorithm created by Dutch computer scientist, John Tromp. Cuckoo cycle was originally applied as a measure to prevent email spams.

The email sender has to perform a certain amount of work that consumes computational power to prove that he does have the need to send out the email to the recipient.

Yet, with its unique design, it sees fit for GPU mining. It focuses more on memory use, meaning the solution time is bound to memory bandwidth rather than the raw processor or GPU speed. Unlike other PoW algorithms that requires maxing out the capacity of your hardware that drains a lot of power which produces heat (which is why most mining factories are located in colder locations/or locations with cheap electricity that can turn A/C on 24/7), a memory-bound algorithm like Cuckoo cycle require far less energy than most other GPU, CPU or ASIC-bound PoW algorithms.

The most up-to-date implementations and findings can be found on his GitHub.

Difference between the Cuckoo Cycle PoW algorithm and the SHA256 used by Bitcoin?

The SHA256 used by Bitcoin is a simple and pure hash function. The computational process of the solution is easily migratable from the CPU to GPU, FPGA, and ASIC.

The above picture is an 8-node, 4-sided Cuckoo Cycle bipartite graph

Cuckoo Cycle is a graph theory-based algorithm. It tries to find a fixed length L ring in the Cuckoo Cycle bipartite graph randomly generated by Siphash. As the scale of the graph increases, the L value increases and becomes more difficult to find a ring that fits the length of L. Solving the solution (i.e., the process of finding a loop) itself requires a relatively large amount of memory to store the sorting of data.

The Cuckoo Cycle algorithm is resisted to ASIC chips. The difficulty and cost to make Cuckoo Cycle compatible on ASIC are much higher than the SHA256 of Bitcoin. It is possible to reduce the anti-ASIC capability by deformation and become an ASIC-friendly algorithm, but it is also possible to further improve its ASIC resistance through deformation as well.

For example, CuckAToo algorithm simplifies and discards the binary end of nodes in the bipartite graph which greatly reduce the difficulty of the solution. However, if all the nodes in the bipartite graph are grouped where all the nodes in the group have mutually dependent relationships, it is necessary to calculate the hash of all the nodes in the group. The difficulty of the solution and the requirements for data cache are then greatly increased. This transformation of Cuckoo Cycle is called CuckARoo algorithm.

Projects using the Cuckoo Cycle algorithm

On the official Cuckoo Cycle GitHub page, a list of projects using this algorithm was announced including AE, Grin, and Cortex.

The list of projects using Cuckoo Cycle on GitHub

AE, also known as æternity, is a new blockchain technology, designed to deliver unmatched efficiency, transparent governance, and global scalability. Minerva Mainnet upgrade(2.0.0) was released a couple weeks ago. AE has a total of 254,396,431 AE and aims to boost 1,000 TPS.

Grin is currently live with its mainnet. Grin uses the Mimblewimble protocol to improve scalability and privacy. It empowers anyone to transact or save modern money without the fear of external control or oppression. Grin is designed for the decades to come, not just tomorrow. Grin wants to be usable by everyone, regardless of borders, culture, skills or access. Grin does not have circulating limit, which means that there is no limit on the total amount, and 60 Grins are mined per minute.

Cortex is building something unique and original. Cortex aims to create a decentralized AI autonomous system that continues to expand the performance boundaries of smart contracts, allowing smart contracts to be actually smart with AI algorithms. In Cortex’s AI on Blockchain ecosystem, AI model developers, AI DApp developers, miners, and users can be linked together through public blockchain to create more AI DApps with real-world use cases. It also help stimulating more high-quality AI models to open source through the tokenomic model and incentive mechanism, which helps to democratize AI research which often led to concentrations of power and money. This is a new AI on Blockchain ecosystem that is independently governed by AI smart contracts. Cortex follows the four-year halving mechanism of Bitcoin. The total amount of CTXC mined through PoW is 150 million, and the first four years yields 75 million, which is halved every four years. Currently, the TestNet is live and the first AI DApp are live.

Grin and Cortex's take on ASIC

Grin

Grin uses CuckARoo (anti-ASIC) and CuckAToo (ASIC-friendly) algorithms in parallel where 90% of Grin is mined by ASIC-resistant CuckARoo and 10% of Grin is mined by ASIC-friendly CuckAToo. This ratio will be adjusted every six months to the point that will fully adopt ASIC-friendly CuckAToo.

Cortex

In contrast, Cortex’s goal is to try to establish an environment where any AI equipment or conventional hardware already owned by everyone to be able to mine. Based on this goal, anti-ASIC is a firm belief in Cortex. The reason for this is that Cortex hopes to allow the mining machine investors in the Cortex ecosystem to have better general-purpose computing capabilities and lay the foundation for the future large-scale AI computing demand market.

Cortex has released a full version of the TestNet which is already using a version of Cuckoo Cycle for consensus mechanism. The AI smart contract feature has also been deployed. The first fully available AI DApp has been created on the TestNet. The development progress of the MainNet is working in progress according to the roadmap, which will be launched in Q2 of 2019. The launched of Cortex MainNet will bring a new wave of not just to AI developers and DApp developers but also to GPU miners.

The first AI DApp on the Cortex TestNet

Conclusion

Cuckoo Cycle is the newly emerging Proof-of-Work algorithm adopt by many projects to establish a friendly mining environment. It generates random bipartite graphs from a provided message and tries to find whether a subgraph with required property exists or not. Different projects have their objectives using Cuckoo Cycle. The algorithm itself has a relatively high anti-ASIC capability and can be modified into other algorithms to adjust the anti-ASIC capability. For Grin, Cuckoo Cycle was used to mitigate against the Bitcoin-style “hardware arms-race” by making it ASIC resistant. For Cortex, it is to lower the mining requirements to lay the foundation for future scalability in AI computing demand market. Cukoo Cycle and GPU mining will lead us to a better mining environment where anyone can be a part of.

Bitcoin Cash Price Briefly Surpasses $170 Following Surprising Gains 0

Bitcoin Cash Price Briefly Surpasses $170 Following Surprising Gains

It would appear most of the bearish pressure which seemed to materialize yesterday evening is no longer in place at this time. Some of the top markets are moving up in a decisive manner, whereas others are still on wobbly legs. The Bitcoin Cash price is surging once again, although it remains to be seen if this trend can be sustained for very long. Weekends are usually somewhat odd when it comes to cryptocurrency trading.

Bitcoin Cash Price Surge is Surprising

Most people will readily agree Bitcoin Cash is a bit of an unusual market first and foremost. While the current price momentum seems to signal the coming few days will be rather interesting to keep an eye on, there is also a good chance this uptrend will come crashing down sooner or later. Since all of these top markets rely on Bitcoin’s momentum first and foremost, it wouldn’t take too much effort to send all markets in a downward spiral pretty quickly.

https://files.coinmarketcap.com/static/widget/currency.js

Over the past few hours, the Bitcoin Cash price has risen by 10.03% in USD value and 9.52% in BTC value. Both trends look very promising, especially now that one BCH is valued at $170, or 0.042 BTC again. Combined with $509.64m in trading volume, there is a lot of positive market momentum to contend with at this time. It is also the first time in a while the BCH market cap surpasses $3bn again, which will please a lot of holders and speculators.

As is always the case when it comes to alternative markets, the social media activity is interesting to keep an eye on. It would appear the “official” Bitcoin Twitter account is trying to convince the Epic Games store to accept BCH as a payment method. While they also advocate for using Bitcoin, it seems a lot of people already oppose the idea of supporting BCH. That is entirely to be expected at this time since BCH simply doesn’t have a great reputation in this industry.

Traders are also contemplating where things will head next for Bitcoin Cash. Crypto Future expected the ETH/BCH ratio to turn out in favor of ETH, but it clearly did not work out as planned whatsoever. Although both currencies are in no way competing with one another, their internal relation in the price department can allow traders to make some good money. It will be intriguing to see how the ETH/BCH ratio evolves in the coming weeks and months.

https://platform.twitter.com/widgets.js

When it comes to the current BCH chart, it is evident this latest uptrend has already seen a minor correction before resuming. TO some traders, that will be an extremely bullish sign, whereas others will expect an even steeper pushback to materialize in the very near future. Considering how the weekend is usually very odd in terms of trading behavior, there is a good chance some form of market shift will occur for BCH, either for better or worse.

https://platform.twitter.com/widgets.js

While all of the signs currently indicate the Bitcoin Cash value will continue to rise, there are rather steep gains in place already. A 10% push during the early hours of Saturday is not necessarily an indication as to how this market will evolve over the next 48 hours. While there may be a further push, chasing the top is not advised at this time. That goes for all other markets which note unusual gains, and not just Bitcoin Cash.
