Chapter 2: William Entriken

Fulldecent, also known as William "Will" Entriken, is a solutions architect, cybersecurity professional, financial analyst, general manager, and civic hacker. He is well known for his efforts in blockchain technology and open-sourced solutions. Fulldecent is also known by the online name Fulldecent. The seminal Ethereum document ERC-721: Non-Fungible Token Standard, which was published in 2018, is widely acknowledged to have been written by him as the primary author. A programming standard known as "ERC-721" was established in this paper, which is credited with laying the groundwork for the digital collectibles ecosystem. This standard allows for the creation of non-fungible tokens (NFTs), which are a sort of digital "deed" that can be used to verify ownership of assets, through the use of smart contracts on Ethereum. Additionally, it was the first time that the term Non-Fungible Token (NFT) was established and defined within the context of blockchain nomenclature. This word was popularized by the blockchain game CryptoKitties, and Dieter Shirley, the Chief Technology Officer of CryptoKitties, is also a fellow co-author of the article that was published.

His achievements as a civic hacker in Philadelphia, which are local to his neighborhood, have gained him acclaim, including from an open source project that is assisting the SEPTA train system. Additionally, he is now in possession of an active Department of Defense Security Clearance, and he has actively engaged with Apple, FINRA, the SEC, and the FBI in his capacity as a cybersecurity specialist.

William Entriken was born in the Greater Philadelphia area, which is also the location of his current residence. Su Entriken, to whom he is married, is the proprietor of a boudoir photography studio in the Philadelphia area, which they jointly operate.

Villanova University awarded Entriken a Bachelor of Science degree in Computer Science, and he was named to the Dean's List. While he was attending Villanova, he also participated in the William Lowell Putnam Mathematical Competition and worked as an apprentice, where he was responsible for programming control modules for warships belonging to the United States Navy. After that, he completed his education at Drexel University, where he received a Master of Science degree in Finance and a Master of Business Administration degree in Investment Management in the year 2008. In addition, he is a member of Mensa and possesses a level 4 certification in Mandarin language proficiency according to the HSK.

At the moment, Entriken takes on the role of general manager at Pacific Medical Training, which is an organization that offers online medical training. His varied career encompasses a wide range of positions in the fields of business, finance, and technology. He has worked as a solutions architect, a software developer at Google, a financial analyst for CDI Corporation, completing mergers and acquisitions, a consultant for Ernest & Young, one of the Big Four accounting firms, and a cybersecurity specialist working with Apple and protecting retail investors' accounts with FINRA, the SEC, and the FBI.

People who hack for the public good, whether on a local, municipal, national, or international scale, are known as civic hackers. Civic hackers are individuals who use or develop technologies for the benefit of the public. It has been brought to people's attention that Entriken has made significant contributions as a civic hacker in the Greater Philadelphia area. He has focused his efforts on projects that attempt to improve government accountability and increase public access to data.

The year 2008 saw the development of a web application by Entriken that compared the actual arrival timings of SEPTA trains in Montgomery County to the times that were scheduled for their arrival. The statement that the trains were running late "every day and usually by 15 minutes or more" was attributed to him by NBC Philadelphia News. In 2012, the application was modified to collect data in real time for thirteen of the regional rail lines that are operated by SEPTA. Despite the fact that the Chief Control Center Officer of SEPTA acknowledged the app as "a nice little tool," he also emphasized that monitoring real-time train timetables was "a very delicate balancing act." The statement "it's good for guidance, but that it should not be your only source for train information" was also attributed to a different official at the SEPTA.

Entriken pursued an investigation into traffic court cases in Philadelphia that were related to "3111 violations" in the year 2014. He was given a figure from Xerox, the company that is in charge of managing the court's data, which stated that the cost of developing a program that could scan and identify all relevant cases inside the database would be $11,200. However, despite the fact that Entriken launched a Kickstarter campaign with the intention of covering this expense, the campaign eventually failed to meet its financial goal.

After incurring $300 in "V-toll" charges from the Pennsylvania Turnpike in 2019, Entriken developed a web application to ease the appeals procedure for such charges and made it publicly available for others to use. This was done in order to facilitate the process of appealing such charges. Upon submission, the application will automatically complete all of the required appeal paperwork. It is a single line of code that is compatible with both Chrome and Safari. There was a half an hour that I spent writing. According to a remark that was published in the PhillyVoice, he stated that it completely contains all five pages. Additional Freedom of Information Act requests were submitted by Entriken in order to study V-tolls over a period of several years; however, the company was ultimately denied access to the data.

Inc. Magazine published an article in 2020 stating that William Entriken had violated a non-disclosure agreement in order to raise attention to a cybersecurity weakness that he had supposedly found in 2008 at the stock-trading firm Zecco, which is now known as TradeKing. The company Entriken asserted that it was possible to initiate illicit trades from accounts that lacked the appropriate credentials by using specific URLs. In spite of the fact that he reported the vulnerability, he reported it publicly and asserted that the company did not solve it.

Entriken has contributed to the writing of five papers often referred to as EIPs (Ethereum Improvement Proposals), which are also referred to as "ERCs" (Ethereum Request for Comment). His most notable accomplishment is that he was the primary author of ERC-721: Non-Fungible Token Standard, which laid the groundwork for the development of NFTs and sparked the start of the digital collectibles ecosystem. Entriken is also one of just two other authors, along with Vitalik Buterin, who is the co-founder of Ethereum, who have successfully published an EIP in the "Informational" category. These EIPs are EIP-2228 and EIP-2982, respectively. By means of EIP-2228, Entriken proposed a formalization of the term "Mainnet" in relation to Ethereum's "network ID 1 and chain ID 1." This phrase had been referred to in a manner that was inconsistent with other names, such as main chain, main-net, main net, and Ethereum's Main Network. All of these names were used interchangeably.

He has been a public speaker at a number of conferences, including NFT.nyc, NFT Tallinn, and Chain76, which he hosted. He has also done so at other conferences.

The previous year, when the United Kingdom made public its intention to implement non-financial transactions (NFTs), Entriken responded by providing public opinion on the tax implications that were involved.

In the context of environmental issues, Entriken has urged for the cryptocurrency sector to address the problems associated with its carbon footprint in order to prevent the business from heading in a "destructive" direction. At one time, he reportedly claimed that "Proof of work should be illegal" due to the enormous amount of energy that it consumes. Additionally, he reportedly stressed the necessity for the Ethereum blockchain to move to a consensus mechanism that is significantly less energy demanding. This protocol is known as "Proof of stake."

Entriken has made it clear that he believes natural language processing (NFT) use cases should be refocused more on identity and healthcare.

The purpose of the conference that he has hosted, which is called Chain76, is to bring NFT use-cases and solutions into alignment with the pharmaceutical business.

Nineteen Eighty-Five, a modernized version of the famous dystopian novel written in 1984, was self-published by Entriken in the year 2021. Therefore, rather than directly authoring the rendition of the novel, Entriken wrote a Perl script program that would automatically replace particular keywords in the original novel with his selection of relevant modern substitutions. This was done in order to parallel the tale with contemporary references. There are copies of the book available in other countries; however, due to copyright restrictions, it is not available in the United States.

ERC-721: Non-Fungible Token Standard is a paper that was released in 2018 by William Entriken, who was the principal author, along with Dieter Shirley, Jacob Evans, and Nastassia Sachs, who were co-authors. The article codifies a standard for non-fungible...
