This story was originally published on by and . ProPublica Kathleen McGrory Neil Bedi The United States designed its chemical regulation system to keep businesses humming with little interference. That decision had health repercussions for ordinary Americans, who are left to carry the burden. As more workers speak up about being , public health leaders are questioning whether these facilities should be allowed to be in a special program that shields them from scrutiny by the Occupational Safety and Health Administration. exposed to asbestos in chlorine plants OSHA’s Star Program, one of its so-called Voluntary Protection Programs, exempts plants with model safety systems from random, unannounced inspections. At least four of the eight that currently use asbestos are in the program, according to OSHA’s website. chlorine factories “On its face, a company whose business model relies on using asbestos does not have an exceptional health and safety management system,” the American Public Health Association’s Occupational Health and Safety Section . wrote in a letter to OSHA last week “There are alternative processes available and used by (chlorine) plants in the U.S. and in other nations.” has long been known to cause deadly cancers and a chronic lung disease called asbestosis. Its tiny fibers are extremely potent; public health experts say there is no safe level of exposure. Asbestos While the vast majority of industries that once used the carcinogen no longer do, two chemical companies, OxyChem and Olin Corp., continue to import hundreds of tons annually for use in their oldest chlorine plants. They use the material as a protective coating on large metal screens that separate volatile chemicals. The companies say they and that workers are rarely, if ever, exposed. But workers , told ProPublica that asbestos dust hung in the air and accumulated in some places until it was inches thick. use asbestos under strict controls at an OxyChem plant in Niagara Falls, New York Workers at an Olin plant near Mobile, Alabama, said they had without any protective gear. Workers at three other plants said they, too, were concerned about the potential for asbestos exposure at their workplaces. scraped dry asbestos off the beams and floors The Niagara Falls facility was part of OSHA’s Star Program from 1996 until its closure late last year, government records show. The plant outside of Mobile participated from 2001 until 2015. In its letter to OSHA, the public health association said it was “alarming for us to read the testimony from former workers about the magnitude of asbestos exposure” at the site in Niagara Falls. The group also raised concerns about the plant’s management using its status in the Star Program “to game the system.” Plants in the program know when most OSHA inspections will take place. Former employees at the Niagara Falls plant told ProPublica they spent months preparing for such visits, and that work in certain parts of the plant came to a halt when OSHA inspectors were on campus. (Even still, inspectors found asbestos on the floor and covering equipment in 2011, records show.) The letter, which included a request for a meeting, was signed by three members of the public health association’s leadership team: Angela Laramie, an epidemiologist with expertise in occupational health; Celeste Monforton, a lecturer in public health at Texas State University who previously worked for OSHA; and Mary Miller, an occupational health nurse who retired from the Washington state Department of Labor and Industries. OSHA told ProPublica it was reviewing the correspondence but declined to comment further on its content. After this story was published, the agency provided the following statement: “Health and safety are OSHA’s top concern, and we are focused on improving our efforts and looking at ways to protect workers from occupational exposure to asbestos moving forward.” OxyChem has repeatedly said it complies with federal regulations. “Dating back to the early 1970s, there have been no violations issued by OSHA related to our handling and use of asbestos in any of our chlor-alkali production operations,” the company said in a statement, which it has provided to ProPublica several times. Olin has not returned calls or emails from ProPublica. Jordan Barab, a former deputy assistant secretary of labor, said it was unlikely OSHA would remove certain chlorine plants from the Star Program strictly because they use asbestos-dependent technology. “There are a lot of companies that handle dangerous materials,” he said. But Barab said OSHA had the power to drop in on plants where workers had complained or even develop a special program to look at hazards specific to the chlorine industry. “OSHA should be looking at these (plants), without a doubt,” he said. “They should have been doing it before, but especially now.” , an Oregon Democrat who has been working on legislation that would ban asbestos, echoed that sentiment. “None of this is a one-off safety lapse,” he said in a statement. Sen. Jeff Merkley “It’s systemic throughout the industry and it’s time for OSHA and safety regulators to step up so not one more American falls victim to this preventable hazard.” OSHA declined to say whether it would investigate any of the plants that use asbestos in response to ProPublica’s reporting. This story was updated to include a statement provided by the Occupational Safety and Health Administration after the story was published.

What makes a brand a brand, and ? As a marketer, I know that thinking — let alone talking — about aspects of branding and how to manage a brand identity successfully, can get a little muddy, and remain somewhat superficial. In this article we’re going to go beyond logos, color codes and fonts, and talk about the elements at the core of brand identity, brand success and effective brand management. what makes a successful brand In branding, style is frequently confused with substance. — Wally Olins What is a brand? What are the first things that usually come to mind when we think or talk about branding and brands? Well, usually we’ll think about annoying online ads, or we'll jump right into the visual aspects of a brand. We’ll think about examples such as Nikes’ swoosh logo or Apple’s, well, apple — but also their and specifically in the case of Apple the design of their products and the experience we have with them. tones of voice These ideas are all reflected in various definitions we find in the world, if we do a quick search. From : Wikipedia A is a name, term, design, symbol or any other feature that one seller’s good or service from those of .[…] Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand’s customers, its owners and shareholders. brand identifies as distinct other sellers Heavy on the visual and more surface-level features, according to Wikipedia a brand identifies one seller’s goods or services as distinct from those of other sellers. Although the creation of brand value is an interesting and very important aspect – fit for a separate article. What is brand identity? Related, but separate as a concept, “ ” also has various definitions flying about the internet and in conversation. What is brand identity? Brand identity offers a fairly useful definition of Brand Identity: Investopedia is the of a brand, such as color, design, and logo, that identify and distinguish the brand in consumers’ minds. Brand identity is distinct from brand image. The former corresponds to the intent behind the branding and the way a company does the following — all to cultivate a certain image in consumers’ minds Brand identity visible elements Here we see that the general approach to brand and brand identity are mostly visual and that they are always about what sets one organization or seller apart from the other. But how can we expand our understanding, vocabulary, and toolsets when it comes to managing successful brands? Wally Olins — The Brand Handbook I find “ ” by Wally Olins to be a very helpful starting point to understanding brands better. The book offers exactly the expansion of vocabulary and tools to get a much better grip on brands, brand identity and brand management. It was gifted to me by my friend and mentor Roel Stavorinus, Corporate Identity guru and one of the Netherlands’ first official register marketers, who was in turn inspired by Olins. The Brand Handbook The multi-award-winning (December 19th 1930–April 14th 2014) was one of the world’s most respected and experienced practitioners of corporate identity and branding. He co-founded Wolff Olins and Saffron Brand Consultants and served as their chairman. Wally Olins Olins advised many of the world’s leading organizations on identity, branding, communication and related matters including 3i, Akzo Nobel, Repsol, Q8, The Portuguese Tourist Board, BT, Renault, Volkswagen, Tata and Lloyd’s of London. He acted as an advisor both to McKinsey and Bain. The Brand Handbook and the idea behind the brand In his seminal “The Brand Handbook” Olins explains with concise penmanship what brands are, how to create them, how to make them work, and how to sustain them. At the core of the brand, he writes, are a clear identity and mission. Olins: “The fundamental idea behind the is that in everything the organization does, everything it owns, and everything it produces it should project . The most significant way in which this can be done is by making everything in and around the organization — its — and performance and, where this is appropriate, ” brand a clear idea of what it is and what its aims are products, environment, communication and behavior consistent in purpose in appearance too. Note how “appearance” comes last, here. The importance of purpose and consistency in branding Olins underlines the importance of working from the inside out when it comes to brand, purpose, and consistency: “Outward consistency of this kind will only be achieved, and for that matter is only appropriate if it is the manifestation of an inward consistency — a consistency of purpose. This consistency of purpose derives from the vision, or the core idea, and is almost always the base from which a successful branding program(me) can be developed. The . It is what the organization is about, what it stands for, what it believes in. All organizations are unique even if the products/services they make are more or less the same as those of their competitors. It is the company’s history, structure, strategy, the personalities who have created and driven it forward, its successes and its failures, that shape it and make it what it is.” core idea drives the organization The rightful place of the visual elements of a brand We are now starting to see the picture. are important, but they’re not at the core of what makes a brand. What is the correct placing in terms of importance, of the visual brand elements? Visual brand elements Firstly, what visual elements are we talking about? Visual elements can be construed as the visible and/or tangible things like colors, typefaces or fonts, taglines or slogans — the ‘look and feel’. This can also incorporate what a product or store smells like, or how a brand experience might sound — as in Gary Vaynerchuk’s “Sonic Branding”. According to Olins out of all the visual elements, the logo or symbol is the prime identifier for almost all brands, its purpose being to “present the core idea of the organization with impact, brevity and immediacy.” “The logo encapsulates the brand.” Together with the core idea, the visual elements mark out the brand territory. Expanding on these two core elements and clarifying the relation between them, Olins further introduces the four vectors through which a brand makes itself tangible. The four brand vectors In his “Brand Handbook” Olins describes the fundamental idea that there are four vectors through which a brand — as defined by its core idea and surface, visual elements — manifests itself. These four vectors are Product, Environment, Communication, and Behavior. — stands for the products/services the organization sells, how they look and feel, and what the User Experience is for these. Product — the physical and digital environment of the brand, how it “lays out its stall”. What does your store or your LinkedIn company page look like? Environment — how it tells people, every audience, about itself and what it’s doing — think, internal and external communications, storytelling, content strategy, copywriting and general tone of voice. Communication — how its people behave to each other and the world outside — think HR policy & processes, leadership and organizational culture, but also recruitment, sales professionals, marketers, and customer service representatives. Behavior The six elements of a successful brand At the core, as you can see the first and quintessential part or element of a brand is its core idea; , mission, and vision. your organization’s purpose The second element would be the visual brand, which is not a “loose” element but one that is ideally derived from the “core idea”, and at almost every step mixed in with the four vectors through which a brand makes itself tangible. You could add the visual brand as an added layer over the graph above, as a way to visualize its place as the second – or maybe, rather, sixth – element of a brand. Think about the colors and/or maybe a logo used in the design of a Product; the brick-and-mortar storefront or conversely the website (Environment); the taglines or slogans — but also colors, layouts, etc.) used consistently in e-mails or campaigns (Communication), and your company logo on the shirt of the customer service representative who just made your customer ‘s day (Behavior). The main goal is to keep finding ways to communicate the core idea of the brand in everything you do. And conversely, to check everything you do with the core idea of your company. I find that these two core elements and four vectors – for a total of six brand elements - make it infinitely easier to think and talk about brand and brand identity, because they help us do it in a structured way. They can also be used as a basis for brand strategy and they are the six elements that you need to at least think about when thinking about creating and managing a successful brand. How to manage a brand successfully Brand management is undoubtedly handled best with a strategic long-term plan, which would be an entire article – if not an entire book - in and of itself. In this article, we focused on the elements that are at the core of brand identity and that should be considered when talking or thinking about brand management. In a future article, we’ll share more in-depth information about managing the processes of creating a brand identity, brand architecture, and managing the evolution of a brand.

The right tools for managing your brand assets — DAM platforms Finally, when you have all of the elements to creating and managing a successful brand in place, along with a fitting strategy to do so, a tool for managing your brand — and most notably and visually your brand assets – can be very helpful. Especially for marketing teams who are collaborating remotely with each other, their internal and external marketing ecosystem and other internal and external stakeholders, a can add a lot of value. Applied strategically, you will be sure to get the most value out of your brand and the related assets by using a DAM system.

How To Hit a Brand Management  Home Run: 6 Key Elements

The dictionary meaning of LIST is a number of connected items or names written or printed consecutively, typically one below the other. In real world, lists are considered in many ways like playlist of songs, collection of your favourite videos, a list of user database and there are many more. But, if you are given a task about handling a list of users and filter out specific users under specific conditions then it becomes a tedious job to filter the list by going through each and every user. In such scenarios, programming comes into place to make your work easier. So, now let us understand in python programming. In python, the list is a mutable, or changeable, ordered sequence of elements where each element or value that is inside of a list is called an . ‘What is a LIST?’ item In string, how each value/element is represented as a character similarly in list, the each value/element is separated by comma where each element can be a string, variable or constants enclosed in [] bracket. Syntax of List: [ , , B2, B3] Nested List: [ , [ , , ], , , [ , ], ] 'LetsUpgrade' 'Batch1' 'LetsUpgrade' 'java' 'python' 'c++' 1 2 'B1' 'B2' 'Exam' Topics to be covered in are as follows: LIST Indexing Lists Lists are Mutable Updating and Slicing Lists Use of operators in List Methods used in List Built-in functions in List Deleting Elements from List Constructing a List with List Items List and Strings Parsing lines Objects and values Aliasing List arguments List Comprehensions Using Conditionals with List Comprehensions Nested Loops in a List Comprehension Debugging We are going understand the above topics through Examples not by theoretical… : #Indexing Lists Each item in a list corresponds to an index number, which is an integer value, starting with the index number 0. For the list COURSES, the index breakdown looks like this: The first item, the string 'Java' starts at index 0, and the list ends at index 4 with the item 'Javascript'. print(COURSES[ ])
OUTPUT:
R 3 If we call the list COURSES with an index number of any that is greater than 4, it will be out of range as it will not be valid: print(COURSES[ ])
Output:
IndexError: list index out range 5 of The above one was Positive Indexing and now let’s see Negative Indexing as shown below: For the same list COURSES, the negative index breakdown looks like this print(COURSES[ ]) Output
Python -3 1 2 #Lists are Mutable : Example:- numbers = [ , ] numbers[ ] = print(numbers)
[ , ] >>> 17 123 >>> 1 5 >>> 17 5 Therefore, as per above example lists are changeable i.e mutable. : #Updating and Slicing Lists Updating We can use indexing to change items within the list, by setting an index number equal to a different value. This gives us greater control over lists as we are able to modify and update the items that they contain. If we want to change the string value of the item at index 1 from 'C++' to 'SQL', we can do so like this: = COURSES[1] 'SQL' Now when we print COURSES, the list will be different: print(COURSES) Output
[ , , , , ] 1 2 'Java' 'SQL' 'Python' 'R' 'Javascript' Similarly, it goes for Negative Indexing. Slicing Lists We can also call out a few items from the list. Let’s say we would like to just print the middle items of sea_creatures, we can do so by creating a . With slices, we can call multiple values by creating a range of index numbers separated by a colon [x:y]: slice print(COURSES[ : ]) Output
[ , , ] 1 4 1 2 'SQL' 'Python' 'R' When creating a slice, as in [1:4], the first index number is where the slice starts (inclusive), and the second index number is where the slice ends (exclusive), which is why in our example above the items at position, 1, 2, and 3 are the items that print out. If we want to include either end of the list, we can omit one of the numbers in the list[x:y] syntax. print(COURSES[: ]) Output
[ , , ] 3 1 2 'Java' 'SQL' 'Python' This printed the beginning of the list, stopping right before index 3. To include all the items at the end of a list, we would reverse the syntax: print(COURSES[ :]) Output
[ , , ] 2 1 2 'Python' 'R' 'Javascript' We can also use negative index numbers when slicing lists, just like with positive index numbers: print(COURSES[ : ])
print(COURSES[ :]) Output
[ , ]
[ , , ] -4 -2 -3 1 2 3 'SQL' 'Python' 'Python' 'R' 'Javascript' One last parameter that we can use with slicing is called , which refers to how many items to move forward after the first item is retrieved from the list. So far, we have omitted the stride parameter, and Python defaults to the stride of 1, so that every item between two index numbers is retrieved. stride The syntax for this construction is list[x:y:z], with z referring to stride. Let’s make a larger list, then slice it, and give the stride a value of 2: numbers = [ , , , , , , , , , , , , ]
 
print(numbers[ : : ]) Output
[ , , , , ] 0 1 2 3 4 5 6 7 8 9 10 11 12 1 11 2 1 2 1 3 5 7 9 Our construction numbers[1:11:2] prints the values between index numbers inclusive of 1 and exclusive of 11, then the stride value of 2 tells the program to print out only every other item. We can omit the first two parameters and use stride alone as a parameter with the syntax list[::z]: print(numbers[:: ]) Output
[ , , , , ] 3 1 2 0 3 6 9 12 By printing out the list numbers with the stride set to 3, only every third item is printed: , 1, 2, , 4, 5, , 7, 8, , 10, 11, 0 3 6 9 12 Slicing lists with both positive and negative index numbers and indicating stride provides us with the control to manipulate lists and receive the output we’re trying to achieve. : # Use of operators in List Operators are used for modifications in lists. We’ll be using the + and * operators and their compound forms += and *=. The + operator can be used to concatenate two or more lists together: LetsUpgrade_Courses = [ , , , , ]

    print( [ ]) open 'mbox-short.txt' for line in line line if not line 'From ' words line split words 2 The program produces the following output: Sat Fri Fri Fri … ( Referrence: pythonlearn) : # Objects and values We will use ‘ ‘ operator to check given two variables ‘a’ and ‘b’ refer to the same object or not: is >>> = >>> = >>> is True
	
>>> = [ , , ]
>>> = [ , , ]
>>> is False a 'banana' b 'banana' a b a 1 2 3 b 1 2 3 a b In the first example, Python only created one string object, and both a and b refer to it. In the second case, we would say that the two lists are equivalent as they have the same elements, but not identical, because they are not the same object. If two objects are identical, they are also equivalent, but if they are equivalent, it is not necessary to be identical. : #Aliasing >>> = [ , , ]
>>> = >>> is True a 1 2 3 b a b a The association of a variable with an object is called a reference. In this example, there are two references to the same object. An object with more than one reference has more than one name, then we say that particular object is and If the aliased object is mutable, changes made with one alias affect the other: aliased >>> b[ ] = >>> print(a)
[ , , ] 1 25 1 25 3 The above method seems to be useful but it is Error-prone and therefore, it is better to avoid using this method on mutable objects like list and for immutable objects like string is not much a problem. : #List Arguments t[ ]
     
S = [ , , ]
delete (S) (S)
[ , ] : def delete (t) del 0 'a' 'b' 'c' print 'b' 'c' In the above example, when we pass a list to a function, the function gets a reference to the list. The caller sees the change if there is any modification in the list parameter done by function as in the above removes the first element from the list. delete [1, 2, 3] None [1, 2, 3] False > >> t1 = [1, 2] > >> t2 = t1.append(3) > >> (t1) print > >> (t2) print > >> t3 = t1 + [3] > >> (t3) print > >> t2 is t3 In the above two examples, the first one is used to and the second one is used to Thus, output of ‘ t2 is t3 ‘ is false unless we assign it as ‘ t2 = t3 ‘. Modify the existing List Create a new list. t = t[ :] 
    
letters = [ , , , , ]
rest = tail(letters) (rest) t = t[ :] t
         
letters = [ , , , , ]
rest = tail(letters) (rest)
[ , , ] : def tail (t) 2 'a' 'b' 'c' 'f' 'd' print None : def tail (t) 2 return 'a' 'b' 'c' 'f' 'd' print 'c' 'f' 'd' If we compare above two examples, the output of both the examples vary and the reason is simple, the slice operator creates a new list and the assignment makes t refer to it, but none of that has any effect on the list that was passed as an argument. Therefore, in second case it creates and returns a new list that is generated. Exercise :  Write a function called chop that takes a list and modifies it, removing the first and last elements, and returns None. Then write a function called middle that takes a list and returns a newlist that contains all but the first and last elements. : #List Comprehensions It is a complex topic and to understand it properly you need go through this below Article: List Comprehension in Python ————————————- THE END——————————————— Previously published at https://olinelearning13.wordpress.com/2020/05/29/python-3-list-in-detail/

The Best 50 Sites to Learn About Data Science

3LAU doing his thang at Royale Boston I was introduced to Justin Blau through a mutual friend who told me about his vision of making music events a better experience for the fans by tokenizing them. My first response was to roll my eyes and say, “Here we go,” and wrote him off as just another dude trying to cash in on Crypto mania. I did some research on Justin and realized that he is a renowned DJ and producer who has worked with many A list musicians and currently tours around the world. My curiosity got the best of me and we scheduled a phone call to discuss his event. Before we talked I jotted down all kinds of questions, and my goal was to test him and try and shoot holes in plans. I am very skeptical of token schemes and I promised myself to be hard on him. Justin and I finally got on a call and we talked for over an hour. I pressed him on many points as he walked me through the who, what, where and how his events would work. Justin never balked, and his sincerity for wanting to make music festivals more fan friendly is what hit home with me. I told him I was interested in doing an interview, but this would not be a fluffy PR piece. I explained to him that many would be critical of the idea, and this interview would be a great opportunity to respond to people questioning his motives. Justin and I stayed in contact via text over the last few months while he was jet setting around the world on tour, and we managed to put this interview together. During this process my respect for him grew, and I can assure you is he is a very grounded and humble guy for being so acclaimed. In the meantime, Justin and his team have been hard at work planning to launch the premier Our Music Festival (OMF) event in San Francisco on October 20th. The headliners are no joke with Zedd, Big Sean, Matt and Kim and of course 3LAU a.k.a. Justin, along with a lineup of other solid musicians. As a matter of fact, when I was writing this intro the OMF Crypto presale sold out in under an hour. Unlike many tokens out there with no utility, the OMF tokens will be redeemed for concert entry. Justin and his crew have big plans to continue to evolve this project, and whether you agree or disagree with the business model it will be interesting to see how this evolves. Justin 3LAU Online Identity: 3LAU, previously Chronocornica RJ: (Real Job) Musician / producer DJ Years in the $BTC game: 3 inactive years, 1 active year How might people know you? Most likely for my music :) How can people follow you? 3LAU on most social platforms What is your background, education or formal training? Before going into music I studied finance at Washington University in St. Louis, Olin. I left school after my junior year to pursue music full time, with blessing from my professors, friends & parents. When did you become interested in Bitcoin and Crypto? The Winklevoss twins are friends of mine, and were building Gemini at the time I was first interested in the space. What is the single best experience you have had in this space? Meeting such incredible, intelligent, and forward thinking people. Tell us your biggest Bitcoin or Crypto fail. When BCH was added to Gdax, and I converted most of my on-exchange binance holdings to BCH to arb the spread between Binance & Gdax… and then Gdax locked the market, and my withdrawal limit was too low to do anything about it… Terrible day(s). Where do you personally get your Bitcoin or Crypto news? All over the place, but lately Medium posts from my favorite authors, as well as aggregator apps! Best tips you can give anyone new to the Bitcoin world? Trust no one and DYOR on anything and everything before making brash decisions about investments! Where did you grow up? Originally New York, but since I was 13 years old, my current home of Las Vegas. What kind of kid were you? I loved video games, legos, and weird music. I definitely didn’t have many friends. What advice would you give your younger self? To embrace my personal oddities and to listen to my parents (both are true heros). Justin got his start DJing small college parties. You are an accomplished DJ and producer, tell us how you got into this? It all kind of happened by accident! I always loved making music, but was inspired to make mashups in college, to access a more mainstream audience. I was previously making more experimental electronic music. A couple of these mashups took off on music blogs, and before I knew it, I was getting requests to play college campuses all over the US. Who are some of the people you have worked with that we might know? Everyone from Ariana Grande to Katy Perry; before they were some of the biggest in the game, The Chainsmokers actually opened for me on tour :) What is it like touring the world as a DJ? It’s not as glamorous as anyone would expect. Making music, and playing shows are two huge passions of mine. What is the biggest show you have ever played? EDC Vegas in 2016, probably the biggest crowd I’ve ever played for. It was also a long term dream of mine. Where can people find your music? The best place would be searching for my spotify profile, just @3LAU — be sure to checkout my latest album called Ultraviolet. In the last year you have launched Our Music Festival (OMF). Explain what it is and what you would like to accomplish? Our goal with OMF is to give fans more power over their festival experiences, rewarding them for their involvement and encouraging them to give back to the ecosystem by telling friends and providing feedback Where is OMF based out of? In year one, OMF will take place at the Greek Theater in Berkeley, CA. We hope to expand all around the world in the next three years with targets in Barcelona, Seoul & Tokyo! Who else is involved in OMF and why do you think it will be successful? I’m lucky to have such an incredible team of music industry leaders, successful entrepreneurs, and tech experts. From my co-founder Adam, to some of our incredible advisors like the founders of Origin Protocol, I think we’re poised to make serious waves in both the music industry and the blockchain space. Many people will scratch their heads when they hear about this and ask why do music events need to be on a blockchain? There are thre primary applications we’re exploring. First is ticketing; collapsing primary & secondary markets with a more transparent means of access transfer / price discover. The entire concept of a “ticket” will shift towards digital assets that enable access, we want to be a part of that journey. Second, fan engagement & loyalty are both increasingly difficult for experience creators to secure. By incentivizing fans to engage more deeply with festival ecosystems, OMF will disintermediate the festival business and cut middlemen that are profiting from arbitrary fees and useless marketing campaigns that fail to engage end-users. Ideally that combats ticket inflation and decentralizes promotional efforts for events. Finally, OMF aims to compensate fans fairly for contributing data, and opting in to share personal information. Most other participants in festival ecosystems have no access to that data, including artists like myself that ultimately drive traffic to live music experiences in the first place. We ultimately want to build a protocol for all events to tokenize, and engage fans at a deeper level. Our branded events will function as pilots for the tech we build, as we build it! In the long term, our vision is to have the fans vote for the artists on the lineup; we cannot wait till we get there! Do you feel the blockchain is an overused buzzword? Yes, and no. It’s definitely the go-to term to describe this giant revolution that humanity is still learning about, but it’s difficult to succinctly characterize this new industry with any other term. It’s a crutch, but necessary in conversation :) What kind of funding have you raised privately to build the back end infrastructure to launch OMF? We started with 1m, and we’re over 2x committed for our strategic round of 3m. This current round is reserved for long term partners who we believe can build the OMF story & provide both labor and capital resources to ensure the success of the project. The next round will be a 12m soft cap 15m hard cap round. In ICO terms, these are small numbers, but it’s more important to our team to protect investors & fairly value the nature of what we’re building. In the long term, we believe that’s key to our success. Just 3LAU tours the world and his home is entertaining sold out venues. Many people might call OMF token a marketing ploy. What’s your response to that? I would just tell someone to check out our all-star team, read our materials, and ask questions. Everyone on the OMF team is happy to answer. How will you differentiate OMF from the long list of scammers trying to make a quick buck off developing a shit coin or token? Our goal is to be as transparent as possible. We aren’t raising money from the public until we know that we’re building completely functional tech. Our #1 priority is the fan experience. You are building OMF token on Ethereum. Why have you chosen Ethereum versus Bitcoin or using other options? We are exploring every option currently. We are primarily using ETH as a means of raising funds, since it has become the industry standard for ICOs, and it’s familiar to investors! Take us through how OMF token will be used by fans at your events? It’s easiest to think of OMF utility tokens like SkyMiles, but that are limited in quantity and have multifaceted functionality. Fans will be able to earn tokens by participating in the festival ecosystem as explained in the previous Fan Incentive Mechanisms section of this paper. The more tokens a fan earns, the higher status they earn within the network, representing their contribution to the network’s success. Simultaneously, tokens earned will be redeemable for tickets, merch, food & beverage at heavily discounted rates; they will also be redeemable for exclusive experiences like artist meet & greets, backstage tours, VIP upgrades, and other elements of festivals that are currently inaccessible to members of the music festival community. How will music fans purchase OMF tokens? The public will not be able to purchase OMF tokens directly until more clarity from the SEC is given on utility token frameworks. We are exploring compliant airdrops to enable fans to start earning OMF as quickly as possible, without necessarily purchasing it directly. Will the OMF token be listed on exchanges? If so, which ones? Unfortunately cannot give more detail here due to regulation, it’s a very unfortunate circumstance. What type of regulatory challenges is OMF up against? Many. That’s why I focused the first six months of this project on compliance measures and corporate structure. I look forward to sharing a lot of my documents with the public down the road! When and where will the first OMF event take place? The first OMF will occur in the bay area on October 20th! Zedd is our first artist on the lineup, but of course I’ll be playing too. We can’t wait to announce the rest of the artists soon, and we’ll be selling tickets ASAP. Describe what fans can expect? In year one, we’re enabling crypto-payments for tickets, and everyone who joins the festival will receive an ETH paper wallet, which we can airdrop to in the future. As our app is developed, fans will be able to import that wallet & we’ll be adding features over time. What artists have signed on to perform? We’ll be announcing our list of artist ambassadors very soon! Will all attendees be forced to use OMF token to buy tickets? Definitely not, our goal is to create a hybridized system that gives all consumers access, that’s the key to fueling mainstream adoption of crypto, on a macro-level. What if they don’t want to? They’ll be able to use fiat, ETH, BTC + more. Will fans be able to buy merchandise and music with OMF token? In year one, we might face network issues, but in year two we hope to enable OMF purchases for all kinds of products and services in the festival ecosystem. Are you afraid this concept might be over the heads of the masses? Ideally we can build a beautiful UI & create simple, educational content to bring the masses to our platform. Thankfully, our founders and advisors have some serious reach. What other technical hurdles do you foresee? There are obvious network / scaling issues for blockchain ticketing. We also have to make sure that festival internet can handle the load. How will fans hold their OMF tokens and what incentive will there be for doing so? There will be multiple staking incentives to access VIP upgrades, early access to tickets, meet & greets + more. The exact incentive structure is still in development. What type of response have you received from the music industry? So far the response has been incredible, the six agent advisors to our project make up some of the most powerful leaders in the live music business. We’re excited to keep expanding our music team as well! What is your end goal with OMF? The end goal is to give fans more control over the experiences they love and look forward to on a daily basis. Disintermediating the music industry as a whole is essential for it to grow, but it’s great to start with the festival business, which attracts so many people, with different tastes, across the globe! The tools of the trade for a boss DJ What is your relationship with the Winklevoss twins? I credit the twins with the reason why I entered the space in the first place. I met them while they were building Gemini, and became intrigued with the potential of cryptocurrencies immediately. I didn’t take the deeper dive until mid-2017 when markets sparked unprecedented upward momentum. Are they down to help and support you? The twins were helpful in pointing me in the correct legal direction for the project. They cautioned moving too quickly without having the proper legal team in place. I’m thankful they encouraged me to double check all of my work. What is your prediction for Bitcoin in 5–10–20 years? I truly believe that we’ll see substantial price appreciation once institutions begin to explore the space. Until then, we’re at the whim of uncertain regulation and constant scamming. I hope the world remains open to the potential that bitcoin holds. Anyone you want to throw a shout out to? Shout out to you PB! Thanks for taking the time to interview me, and educate the masses on the potentials of DLT! Where can people learn more about upcoming OMF events and tokens? You can check it all out at omf.io and stay in touch on our telegram channel :) https://t.me/ourmusicfest Any last words? Huge thanks to PB for conducting this interview.
