Monero-Classic (XMC) is a hard fork of Monero (XMR), announced on 29th March. Part of Monero's development is that it hard-forks every 6 months, this is completely normal so not a surprise. After one of these scheduled hard-forks Monero retains the ticker symbol 'XMR' as well as the upgrades from the hard-fork; on the 6th April hard-fork it had changes including resistance to Cryptonight ASIC miners. If people disagree with these hard-forks, they can create their own versions of Monero. The strong financial incentives against this hard-fork, resulted in 4 different entities that each has created versions of Monero that still support ASIC miners, with their own new ticker symbols: Monero (XMR), the coin supported by the core Monero development team Monero Original (XMO), announced on 29th March Monero 0 (ZMR), shared on Reddit on 31st March 2018 MoneroClassic (XMC), first Tweet on 4th April 2018 Monero-Classic (XMC), first Tweet on 5th April 2018 On the project website, the person behind Monero-Classic identifies himself as “PZ, an early Bitcoin evangelist and blockchain eco builder”. PZ's message on the website: Hello, everyone! I'm PZ, an early Bitcoin evangelist and blockchain eco builder. Most of you know me because of my efforts and adherence to the ecological development of blockchain industry. In the past few years, I saw Bitcoin community and Litecoin community both fell apart for long time due to different ideas , and the development of main chains was unable to move forward. So I organized Litecoin International Round Table Forum and Bitcoin International Round Table Forum in 2017. The two meetings were very successful. The upgrade of Litecoin and Bitcoin also went on successfully. Recently, our team noticed that XMR (Monero), the world’s largest anonymous currency, is about to change the PoW algorithm, and plans to further change it twice within 1 year. As we all know, the reason for this algorithm change is that many companies (BITMAIN, PinIdea, etc.) have developed specialized mining machines for Monero. Actually, the emergence of specialized mining machine for a cryptocurrency is normal market economy phenomenon. In the 10 years since the cryptocurrency community was born, we have seen the birth of specialized mining machine for Bitcoin. Then there emerged Litecoin, which was expected to be against specialized ASIC mining machines, using script algorithm which was considered to be'against ASIC' at that time. While after only two years, there appeared specialized mining machine for Litecoin. We considered about whether to change algorithm to be against specialized ASIC mining machines or not. However, after prudent and serious discussion, we believe that for any kind of valuable algorithm, the emergence of mining machine is only a matter of time. Finally, we made our choice to accept the existence of professional mining machines. Now more and more high-value currencies (algorithms) have respondent specialized ASIC mining machines, which has become a common phenomenon in the industry. Is the existence of specialized mining machines completely useless? Obviously, this argument is unfair. The emergence of specialized mining machines will indeed accelerate the rise of problems such as centralization of computational power. But we should be reminded the fact that emergence of professional mining machines will also greatly improve network security. If there are professional mining machines, the events like “Monero was attacked by more than 500,000 botnets” could be avoided. We understand that Monero team expects to stick to the expectations and work of Monero's “against ASIC mining machine”. For a long time, due to the excellent work of Monero team, XMR and its community have achieved great development, providing much valuable contributions to the entire cryptocurrency community. In the community, many people agree with this hard fork of changing algorithms. However, I feel that there is still a part of people who want to maintain the original algorithm and accept the existence of mining machines. They should be heard and respected. We believe that the two ideas of 'embrace ASIC mining machines' and 'against ASIC mining machines' both have their own strengths and weakness. At present, the vigorous development of the global cryptocurrency ecology is precisely due to the emergence of various ideas of different people. The collision of different ideas has brought out the flourishing of various digital currencies. We always believe that the ecological diversity of cryptocurrency community is much conducive to the birth of a more secure, stable, prosperous and beautiful encrypted world. We can, and should, allow these minority of people, who are adhering to a different idea, be given equal opportunities with the majority, and the free market will make its own choices. Therefore, we believe that these two thoughts should be given equal opportunities for development. We will make our best efforts to maintain the Monero system before this algorithm change, thereby preserving the fire that gives the ecology more potential for development. At the same time, we also invite developers, mining machine manufacturers, trading platforms, miners, purses, and others in this ecological chain to join us, so that the network ecology can gain more possibilities!

Gnosis is a prediction market platform built as a decentralized application (dapp) on the Ethereum network. The platform includes a multisig wallet as well as a Dutch Exchange, but we’re just going to focus on their flagship product, the prediction market, for this guide. More than just building a prediction market, though, Gnosis is creating an entire infrastructure layer that you can use to build your own prediction market app. A prediction market utilizes user predictions to aggregate information about future events. Users in the market trade tokens that represent the outcome of a certain event. Because some outcomes are more likely to occur than others, these tokens end up having different values in the open market.Olympia is Gnosis’s test version of their prediction market app. They host free tournaments in this product, so you get a chance to try it out without having to spend money. Every two days, the team allocates you a certain amount of Olympia (OLY) tokens that you use to bet on different prediction markets. If you do well in the market, you win Gnosis (GNO) tokens. You can sell GNO on the open market which gives them some monetary value. The next phase of Gnosis is its Management Interface. The team released a beta version in December 2017 but haven’t announced a date for the main net release. The Management Interface is basically your dashboard for Gnosis’s prediction markets. It’s here that you check your balance, participate in markets, and even create your own market. Gnosis includes two types of tokens: Gnosis (GNO) and OWL. GNO are the ERC20 tokens that the team sold during their ICO. They created 10 million GNO tokens and aren’t minting any additional ones. These are the tokens that you see being traded on the open market. By staking GNO, you receive OWL tokens. To do this, you must lock your GNO in a smart contract making them non-transferable. The amount of OWL you receive is dependent on the length of your lock period as well as the total supply of OWL tokens in the market. The team is aiming to have 20x more total OWL than the average amount of monthly OWL usage over the previous 3 months. The Gnosis team is led by Martin Köppelmann (CEO), Stefan George (CTO), and Dr. Friederike Ernst (COO). Köppelmann and George began working on the platform in January 2015 as one of the first ConsenSys partners. By August of that same year, they launched the alpha product as the first major dapp on Ethereum. In April 2017, the project held somewhat of a controversial Initial Coin Offering (ICO). Using a dutch auction style of raising funds, the team hit their $12.5 million hard cap in ten minutes while retaining 95% of the tokens. Amidst backlash, the team locked the tokens in a vault and have promised not to dump them on the market. They’ll give at least a three-month warning before selling any of the tokens. The team includes quite a list of reputable advisors including Joseph Lubin (Ethereum co-founder and ConsenSys founder) and Vitalik Buterin (Ethereum founder and chief scientist).
