Mountie Lee strong knowledge and experience for cryptography, security and payment industry.
started W3C activity at 2012 for PKI and Web Cryptography
David Samyde My connection to the BCTechnologies is through my university advisor Pr Quisquater who is one of the few people initially mentioned on the first paper about BitCoin. Having studied cryptography with Pr Quisquater at Universite Catholique de Louvain, I have an interest in cryptology and applications. My interest is about cryptoability and the possibility to adapt to post quantum algorithms later. The NSA deprecated ECC in August 2015 and NIST will announce new Post Quantum families of algorithms, I am particularly interested in the cryptographic ability that will be required when the algorithms in use in BCTechnolgies will be at risk and require replacement.
Regarding my personal or professional resources present on the web, I am the author with Pr Quisquater of some early papers on side channel and fault induction, mainly ElectroMagnetic Analysis and EM fault induction. I have worked as a security engineer or security architect for few Fortune 500 through the world.

ERIC E. COHEN The world is looking to the Blockchain and related electronic distributed ledgers as a solution for a wide variety of challenges, calling it the “Global Ledger” and an immutable and secure audit trail. There are few others who have been as directly involved with global standards, academic, business, audit professional and government communities in discussing the need and attributes of an open, transparent, authentic, secure and semantically-rich distributed ledger and audit trail, especially as applied to corporate reporting, as I have.

As a co-founder of the XBRL consortium, focusing on revolutionizing the data, rules and processes of the corporate value "information bus" and the audit information supply chain, and as the Father of XBRL’s own "Global Ledger", an XML-based specification for expressing a broad variety of transactional interactions in a standardized, holistic and generic fashion, I have been promoting a cryptographically-supported, semantically-rich, Web-available audit trail for over fifteen years, and have worked with virtually every community seeking to develop ledger interchange formats and protocols and related audit data standards internationally. This includes prior work with the OECD and present work with the ISO, and with the United Nations' CEFACT effort as a domain coordinator over accounting and auditing standardization. These efforts focus both on data standardization and considerations of business rules, agreements, assertions, formulas and access rights throughout an audit trail or open business process.

Along with semantic standards focusing on XML, I have been involved previously in the W3C’s security standards efforts with such an open, public and cryptographically supported anonymous audit trail in mind, contributing in particular to the initial development of XML Encryption and later providing use cases for continued considerations of XML Security, especially related to identity and digital signature issues. I have also been involved in a wide variety of signature and identity efforts with other standards and professional groups, in particular working through authorization, workflow and privacy issues of parties throughout the audit information supply chain.

I have also heavily supported the academic community in its exploration of semantic and security standards for moving from document-centric to information-centric environments for continuous monitoring, reporting and auditing, and the practical use of the transparent and trustworthy audit trail as it is established.

On Twitter, I am @Cybercpa, focusing on Blockchain and bluegrass, audit data standardization and humor.

I am also an author and speaker on accounting technology topics; I wrote the first book about the Internet's relevance to accountants and the first article for the US accounting profession on the topic. I created one of the earliest web sites for accounting technology, which circumstances have not permitted me to maintain - http://www.computercpa.com.

My firm's blockchain presence starts at http://www.pwc.com/us/en/financial-services/fintech/blockchain.html ; my opinions do not necessarily reflect those of my employer.

A web site focusing on issues related to continuous monitoring and audit is http://raw.rutgers.edu

A picture of a Blockchain-like open, public, transparent transactional black box for operations, audit or other uses can be found in Figure 6 of this document of mine from more than a decade ago https://www.oasis-open.org/committees/download.php/16709/Tax%20XML%20AuditTrail_60215 showing a cryptographically secure, inalterable, web-based transactional audit trail repository

Tarique Bhuiyan I am Tarique A Bhuiyan (pls call me TaB) and I am the Founder, Chairman and CTO of a Blockchain focussed technology start up called Hashkloud PTy Ltd based in Sydney, Australia. I am extremely pasionate about Blockchain technology and very strongly believe the technology will disrupt many industries especially services industries. My passion for Blockchain technology has led me to enroll myself on a Research Dotorate of Business Administration at an Australian university in part time under Australian Research Training Scheme. My current career goal is to become not only become an academically expert in Blockchain, but also professionally - a combination that is very much a sought after credential required to promote Blockchain as a technology.

At Hashkloud, we have already developed a product (currently at Beta stage) which is a digital platform for customer KYC and Verification of their Identities powered by Blockchain. The idea behind is that we would like to create an internet of services where all service data and documents that relates to an individual will link back to that individual's identity and all verifiable via Blockchain while keeping the integrity and irrefutability of the identity and all other requests or instructions of the individual while applying for that service.

Poon Joseph An author for The Lightning Network, a decentralized scalable payment mechanism capable of millions to billions of transactions per second across the network. Capable of decentralized atomic crossing of different blockchain asset classes (exchanging between blockchains with different consensus rules without a centralized clearing depository). Millions-to-billions of tx/sec allows for use cases such as pay-per-article micropayments. Working on a software implementation and library to be hooked in by wallets, browsers, etc.

Geater Jon While the organizers are understandably keen to avoid too much discussion of payment technologies at the workshop, my experience with building and deploying web payments systems is highly relevant to the task at hand. I was lead architect and software developer of the nCipher payShield HSM which was built specifically to service the emerging 3DSecure/SecureCode market, a standard aimed at bringing physical cards onto the web. In designing and building this product I discovered serious flaws in the card schemes’ original cryptographic protocol designs which were fine in the context of the EMV walled garden but unsuited and potentially vulnerable in the web context.

Later in my career as Chief Technology Officer at Trustonic I brought security to large-scale natively online applications in a variety of use cases including sensitive online identities, multi-party trust, bitcoin wallets and blockchain platform companies. Practical issues in the areas of standardization, deployment and usability are legion and in order to get something to market compromises have to be made at almost all levels of the stack.

Now in my current role I am actively handling many projects and products in a wide range of industries at all stages of ‘digital transformation’ as they transition security-sensitive operations to the cloud, to web, and more. Blockchain is high on the agenda for many of these conversations, and the requirements vis-à-vis permissioning, form factors, confidentiality and legals are highly varied.

Appreciation of cryptography ‘in context’ is going to be essential in making web-accessible general blockchain standards practical. I intend to bring this experience to the workshop.

Potter Stephanie I am a research coordinator at State Street Bank. Currently, my team and I are creating a machine learning based platform for organizing and suggesting sell side research to institutional investors. Our team falls under a larger group called innovation ventures which houses blockchain consortium efforts, social media sentiment analysis for stock performance, new efforts within big data management as well as investing or acquiring financial technology startups.

Within the past year I have gone to a handful of conferences, primarily in San Francisco and Cambridge on new technologies within finance. All of the conferences have had panels on leveraging blockchain to house digitally native asset classes and loan agreements.

Although I have researched blockchain technologies in finance for over a year, I have recently become more interested in the idea of a blockchain based identity management system. After listening to a presentation on Ethereum at a financial conference I began to do research on how Ethereum could change identities are used online.

My personal research has lead me to believe that creating an identity system could be a major step towards more efficient international research endeavors especially in medicine, genetically modified organisms, nanotechnology and robots/drones. To enable this I believe large corporations, such as my own, have a role to promote interoperability through supporting and assisting to create identity management systems.

Juri Bulovic My goal is to be involved with the "Blockchain community" and stay up to speed with the latest developments. I want to further expand my blockchain knowledge (especially learn about the interesction with the web - discussion topic i haven't heard before). Attending a workshop like this could inform new partnerships opportunities for Fidelity
Alex Waters Contribute any of my perspective or experience if it is useful to the discussion. There have been a lot of highs and lows in the past few years, and I hope my experience can be utilized.
ERIC E. COHEN Broadly, I would like to contribute my somewhat unique background in audit, technology and data and security standardization to this vital effort. As noted above, I have been active in W3C, OASIS and numerous standards organizations to help make the vision of what might be accomplished by the Blockchain into reality.

More specifically, although it is not my only interest, the audit information supply chain is a primary focus for me. Therefore, supporting the discussion of topics on simplifying access to information in the Blockchain and making appropriate content available to end users, while protecting the privacy of parties as appropriate throughout is a topic of particular interest.

In the case of the corporate audit trail, the process begins with transactions for an organization being logged or captured in a blockchain, where those entries are controlled, authorized, complete and discoverable where appropriate.

Auditors’ identities, and authorization to act as auditors with appropriate attributes, might be captured in a blockchain (identity management). Different audit regulators (by region or by purpose) might maintain different blockchains, and some means of getting information across them may be necessary.

Auditors would use the blockchain as a primary source of evidence.

They would deliver their opinion on financial statements or other management assertions, where that association may be captured in a blockchain, capturing hashes of the financial statement and the auditor’s report (or the content itself) for stakeholders to be able to confirm the authorization of the auditor and the association with the report.

Regulators would have an important role in this scenario, but let’s move to the investors; stakeholders would have access to the information in appropriate detail.

Making that access "actionable", the stakeholder may be able to receive a “token” as part of a smart contract for reviewing the materials for an appropriate period of time, and reliance on the auditor’s opinion may be anonymously captured; however, the stakeholder can prove that reliance at a later time if needed, for example, in court.

Although the transactions would likely flow automatically, the other steps may benefit from personal interaction in a browser to find appropriate ledger entries, check identities, sign interactions, and assess and agree to or otherwise monitor the current status of smart contracts, amongst other tasks.
Boaz Sender My goal is to explore opportunities for creating and standardizing the language and concepts for distributed, custodial and fiduciary trust on the web.

To create a standardised system of metadata, so that creators of that data can be found, credited and then a transparent distribution and accounting mechanism developed so that creators and consumers can exist in a sustainable digital economy trading all forms of data in a frictionless, secure, private and fair trade environment.

Tamara Bennett Understand the possibilities of integrating blockchain in the digital payments ecosystem.
Jonathan Harvey-Buschel My goals are to serve as a source of information regarding properties of Bitcoin, blockchains, and consensus mechanisms as well as to better understand both what existing features of the Web could be improved with a Bitcoin-inspired solution and what new capabilities would make sense to implement with a Bitcoin-inspired solution.
Seana Pitt Understand the extent to which blockchain may become a pivotal technology in the payments space, particularly possible integration in peer to peer payments systems and mid-tier B2B.
Shilpi Kumar We are navigating many concepts around identity and micro-transactions that should be consistence with the solutions and ideologies that are evolving in the cryptocurrency leadership circle. As we come to the helm of deploying large volumes of devices that are secured with blockchain-secured contracts, we can essentially become the "off-chain" oracle for physical transactions that will reconcile with the blockchain and standard mechanisms. My goal is that we can be present in the conversation, observe any current consensus or divisions, and represent the "IoT" and industrial perspective of our customer and partners.
Tarique Bhuiyan At Hashkloud, we are trying to come up with technologies powered by Blockchain to revolutionize services, any service. We are working on the concept of 'Internet of Services', more precisely 'Internet of Service Data and document objects'. We believe that if we could create an ecosystem of documents and / or data objects required by various services, it is possible to create and ecosystem of inter-connected services thus making services delivery easier by the services organizations while at the same time creating fantastic service experiences for the service seekers. At the core of this ecosystem is the service data objects of service seekers' identifications. Unless we have a framework of such ID data objects of the service seekers while still keeping the integrity, privacy, etc. of such data, it will be very difficult to attain such 'Internet of Services' ecosystem. My goal to attend this workshop is to highlight this and get some standardized framework of service data object especially with regards to ID data objects of service seeking individuals or corporates powered by Blockchain technology.
Ravi Variar I would like to learn from and contribute to distributed ledger technologies from a Data, Messaging, Security and Performance perspective. I also have some experience with regulations which will be very important to make this successful.

Poon Joseph Meet people! Develop the base for future work on specifications/software. Alignment of stakeholder needs.
Geater Jon To share my knowledge and experience and to learn from others.

I think Blockchain has tremendous potential to underpin secure shared storage of data all kinds of data driven systems and I am actively looking at using the technology to overhaul legacy commercial systems.
Peter Salvitti I have a couple of goals in mind:

1. Explore opportunities for easing the (data/person) integration challenges that most modern Universities face wrt/ incoming and outgoing students and their achievements;

2. Explore opportunities for new designs in the academic certificate space such that current challenges and limitations are eased (e.g., ask me about my non-digitized transcript and the failed background check sometime)
Jae Kwon Educate peers on Tendermint and GnuClear, and receive feedback.

Julian Smith Exchange industry insight on the technology underpiing projects in the space.
Alex Van de Sande Exchanging ideas about how blockchains and smart contracts can shape the future of the browser
Potter Stephanie My primary goal for the workshop is to identify how large institutions (especially banks, such as the one that I work for) can support interoperability and blockchain based identity management systems. In the short term I would like to create a narrative on the role of large corporations in supporting a blockchain based identity management to galvanize efforts on defining the changing role of fiduciary relationships.

My secondary goal is to contribute to and gain deeper thought on the ethical basis needed for identity management systems to contribute to an enlightened democratic society.
Questions that surround this should define where we, as a society, draw the line on the information large companies or governments need from it’s clients or citizens to facilitate innovation and healthy societies. If we create an identity system that gives the users autonomy over their information, but society does not have a strong opinion on the dangers of oligarchies in the digital age, both in government and businesses, democracy and free thought will still be at risk.
For example- if in the future an identity management system was adopted, and large insurance corporations could not unknowingly collect information on its clients, but instead had to gain permission from the clients to access deeper personal information by offering incentives to the client - the risk of oligarchy would still be present. The insurance company in this example could make it too financially burdensome for the client to withhold their private information.

Legal disclaimer: This is my personal opinion and not the official position of my company.

Won-Beom Kim Discussing possible pathway for adopting standards in blockchain space.
Harry Halpin I'd like to see a successful workshop that introduces the advantages and disadvantages of open standards, as learned from the W3C and IETF, to the Bitcoin and wider blockchain communities. If there is a useful intersection of blockchain technologies and the Web, I think the W3C would be good place to create a standardized Web API.
Manu Sporny Explore what W3C could do in the space by networking with others with interest in W3C and Blockchain. Participate in discussions around generalized ledgers that use W3C technology namely around "Identity"/Verifiable Claims

3. Workshop Goals

What goals or outcomes do you think the workshop should focus on to be productive?


Responder Workshop Goals
Alex Munoz Mendieta
Rick Dudley
Christopher Allen Smaller, well focused interoperability discussions. Some common APIs and data structure. One interesting possibility is smart signatures.
Mountie Lee - web as PSV node of bockchain.
- improve presentation level or wallet
- improve server level communications between nodes.
David Samyde - 'Hurding the cats' around BCTechnologies on the web
- Protocols and 'standards' to increase inter-operability between BCTechnologies
- BCTechnologies architecture
- Roadmap for the community and W3C to guide and follow BCTechnologies in an industrial/practical approach
- Optimized API and primitives definition
- 'Transaction' oriented execution
- Stability in time and robustness
Adrian Hope-Bailie - Establish if blockchain technology could be used to replace/compliment any existing component of the Web platform.
- Lay the groundwork for interoperability protocols for ledgers and registries that use blockchains
Juri Bulovic Identify key areas for further exploration and research - Why something is important and matters and how best we can work together to tackle it.
Alex Waters I think the bitcoin community could benefit greatly from a standards body. Everything from defining terminology to use-case message-system variable names.

While working on Bankchain, there was a high level of interest in cooperation between the various competitors to implement standards and meet regularly so that there could be future compatibility between systems.

There are also a lot of security and project-specific technical pitfalls common to finance that should be well defined so that new developers can avoid introducing known exploits to their architecture.
ERIC E. COHEN I think the goals stated at https://www.w3.org/2016/04/blockchain-workshop/ are quite valid. Should Blockchain and electronic distributed ledgers live up to a fraction of their potential, standardizing the web-based interface may require ongoing consideration, starting soon, so that the "right steps are taken at the right time".

Related discussions are taking place in many other standards communities. The ISO is considering whether it should have a role in related standards - https://www.ansi.org/news_publications/news_story.aspx?menuid=7&articleid=c91c48a9-7c64-4a36-a76b-81eaa8c0923e and ISO/TC 68, the OMG Finance Domain and other communities are also exploring their role.
Boaz Sender * Evolve our language for distributed network trust in the browser.
* Establish use distributed identity use cases that create consumer and institutional value.

I'm less interested in sketching browser APIs here, but I would be happy to contribute in that way, too.
Youngwhan Lee It would be good if the DLP community work together to make a Recommendation for DLP Standards in W3C Blockchain Community.
Sanjeev Vittal Narsipur Fundamental Building Blocks for creating robust Blockchain governing process.
Justin Newton Where does it make sense for open standards blockchain solutions to be used in web applications, and for those use cases how do we define the structures and interfaces that need to be standardized to allow broad adoption and diverse use cases.
Alan Wunsche I would suggest deep dives on important topics in the blockchain space such as scalability; privacy; Interoperability.
Tyson Goings Helping people come to a common understanding of the current blockchain/distributed ledger landscape and attempting to arrive at a consensus around how to approach standardization would be helpful. The technology is so new with different 'flavors' offering different solutions, I'm not convinced that we are ready to start standardizing just yet and believe there is much to be discussed.
Vinay Mantha There should be no marketing-spin of any sort in the workshop. Active collaboration between participants from the industry in discussing the best practices in the block chain industry will be very helpful for everyone. Also looking for MIT's expert guidance on approach/tactics/platforms and architectures.
Alin Tomescu A focus on how the Bitcoin blockchain, specifically, can be used to bootstrap trustworthy systems. In particular, I am very interested in public-key directories built on top of Bitcoin, but in directories that are more efficient to query than Namecoin or OneName (or Blockstack. more recently). Downloading the blockchain should not be necessary.
Geoff Cohen It's very early in the discussion: even producing a solid, well-specified set of questions or a research agenda would be progress. Identifying concrete use cases would be helpful for a variety of analysis.
Denis Nazarov Agreeing upon prototypes and MVPs as deliverables that participants can collaborate on, with the goal of telling the world compelling stories about how decentralized technologies solve real problems today that existing centralized solutions are unable to.
Hélène Muddiman To concentrate on what the world and the Internet will be capable of in 5 years time.

The enormous amount of content that will be available if we put into place the ability to output accurate metadata, in a format that can become pervasive, then platforms and tools can be built on top when the technology is powerful enough to accurately search and account to those billions and billions of digital files and transactions.
Tamara Bennett Specific use cases of blockchain integration in financial systems and the pros/cons of this integration.
Jonathan Harvey-Buschel One goal is to have attendees leave the workshop well-informed on the properties of both the Web and blockchains. Specifically, the attendees from the various blockchain communities should gain an understanding of the areas in Web development where a blockchain would be useful, and the attendees from the Web improvement community should understand basic properties of blockchains and what problems they are most relevant to.

Another goal is to connect people from these communities with each other such that discussions started at that workshops and plans initiated can continue into the future. For any Bitcoin-like implementation of a feature for the Web, attendees to the workshop should be the first ones contacted for feedback and review.
Seana Pitt Clarity of the most appropriate relevant uses for Blockchain, demonstration of how blockchain drives value beyond the bitcoin model
Shilpi Kumar I suggest we work towards a dynamic model for "standardizing" the process of change and adoption of new technologies in this space. Achieving an outcome of total agreement on best solutions or ideologies may not be as fruitful in the long term because so much is changing and being introduced at a rapid pace.
Tarique Bhuiyan The outcome that I believe the workshop should focus on is to cme up with a framework of Identity systems powered by Blockchain technology while still keeping data privacy and integrity factors.
Ravi Variar (1) The top two aspects would be security and regulatory themes. (2) Consensus and Trust building will have to support the above two seamlessly (3) Finally the usage will be successful with ease of deployment and management.
Frederick Hirsch Have a useful outcome in understanding the privacy risks/concerns/implications of use of blockchain technology, review interaction with identity systems, decentralized or not, identify key concerns and developments.
Arnaud Le Hors Figuring out where the W3C might possibly play a role down the line.
Haiyang DING Personally speaking, I think the best way to be productive is to be focused on specific scenarios, in which security, performance, system and process design could be included.
Gilles Gravier Identify structures for developers and integrators to set up and operate to enable seamless customer deployments into production.
Shammari Khan Mass adoption of Bitcoin Technology.
Mikko Ohtamaa Web browser and blockchain interactions
Poon Joseph 1. Meeting the various stakeholders.
2. Understand needs, use cases, etc.
3. Understand limitations in the problem space
4. How to adjust our protocol/code/specs.
5. Understand the scope of the browser within this problem set.
Geater Jon Don't get distracted by bitcoin: W3C and Blockchain should be generic.
Focus on interoperability specifications, not implementations.
Peter Salvitti 1. Explore ways to help institutions (like Universities) #LoseTheSSN and provide a trust factor valued by all ... currently the SSN is the one identifier that causes the most angst: warehousing it, protecting it, sharing it, etc.

2. Explore ways in which integration (connectivity + interoperability), privacy, and security can be achieved in a resource-efficient manner;l

Jae Kwon Map out the various technologies roughly as layers or components, and compare them. For example, Tendermint vs Hyperledger/OBC, IPFS vs Storj, Ethereum vs ... etc.
Julian Smith
Alex Van de Sande How to get all the current projects aiming to decentralize the web under the same roof
Potter Stephanie create a narrative on what is going on in blockchian and how it relates to the future of information and relationships that is marketable.
The narrative should include a philosophy component, possibly Locke and/or Madison; be defined by the major discourses within technological abilities and challenges - not generally agreed upon ideas about blockchain; who specifically is needed to advance efforts in interoperability and identity management for next steps to unfold eg. Government officials, businesses, universities; and how members of the W3C event can group together to be influential thought leaders.

Legal disclaimer: This is my personal opinion and not the official position of my company.
Lauri Ilola Primarily sharing experiences to advance DLT ecosystem. Identifying and sharing bottlenecks and problems with current DLT implementations to decide if standardization could help solve some of these issues.
Won-Beom Kim Coordinated efforts on building standards on blockchain should be commenced.
Harry Halpin I think the following goals make sense (from easiest to hardest):
- Explaining the W3C Patent Policy, W3C Process, as well as other standards processing such as the IETF and "Note Well".
- Determine if Bitcoin wallets have interoperability with Web Payments and if new work is needed.
- secp256k1 Curve support and schnorr signature in Web Crypto
- Intersection of Web Authentication and Blockchain
- Generalized blockchain API for auditing
Manu Sporny Focus on components and protocols that need standardization, then determine if W3C is the right place to have that discussion.
Marta Piekarska 1. Definitions - so we know what we are talking about. A dictionary of agreed upon phrases and terms
2. Agreed upon directions - this is the time to start the standardization process. It is early enough to agree on common criteria and how to do things right before we start messing it up. But we need to agree what are the dos and don'ts
3. An established working group that collaborates towards creating standards in Blockchain on the Web
Eileen Quenin
Mike Warner The concept of an interledger API standard is brilliant. Hypothetically, if there is one day a 'fedcoin' it needs to work seamlessly with a hypothetical 'worldcoin'. The work you are doing can potentially smooth the way through the inflection point we are approaching. Done wrong can have a downstream impact on social stability. Done right you can help society increase the velocity of money which is the foundation for the pursuit of happiness and a strong GDP.
Victoria Lemieux *core technologies required and any gaps for different use cases
*applicable standards or new standards that may be required, as well as whether standards will help or hinder innovation at this stage
*governance and development issues in the blockchain that may need to be resolved to support development of effective web-based technologies
Darrell Duane The workshop should work towards finding points of standardization whereby many parties can share in schemas, processing protocols, Decentralized Identifiers, and other alignments that allow for collaboration among large, small and individual entities. Further, the workshop should examine the possibilities for creating greater trust frameworks and consider how to allow for reputation and sybil management to occur.
Ethan Buchman the establishment of simple standards for interoperability across platforms
Allan Third A clear, use-case-driven map of where the most useful overlaps and interactions between blockchains and the Web are to be found, and how existing or new Web standards might help.
Martin Kurze 1. Real world use cases/applications, may be even business models,
2. Proposed next steps for w3c and the community in standardization activities: new committee? collaboration/extension of an existing group? etc.
Bart Suichies - deep dives on important topics in the blockchain space such as privacy & interoperability.
Andrei Sambra

Alex Munoz Mendieta
Rick Dudley
Christopher Allen I'm very concerned that we find and deliver on opportunities that will not take years to standardize. The blockchain community will not wait that long.
Mountie Lee
David Samyde Blockchain is a possible future, but the practical management of chain that will grow forever and evolution of miners will require some clear thinking to be widely adopted at the next giant level. A standardization body is required to 'give wing' to this technology and reduce the number of iterations before the 'bird leaves the nest'.
Adrian Hope-Bailie
Juri Bulovic
Alex Waters I plan to avoid advocating for any single entity. I have been working on a new project totally unrelated to the industry since February and hope that I can be totally objective and not be captured by ideas due to who's backing them.
ERIC E. COHEN Not wanting to be redundant, the features that Blockchain 1.0, smart contracts 1.0 and related agreements promise undergird the potential "business Web" that I have been promoting for over 15 years. Whether it is they they will succeed or some eventual successors, efforts around XML and Web security, URIs and other W3C recommendations seem highly relevant to the success of Blockchain implementation and considering their evolution in light of the many potential uses a valuable use of time and effort.

1) ID , i.e. recognise those who create and how to get hold of them (ID is scary for some people so I use the term recognise)
2) build an archive / registry of all IP (database is a word synonymous with the failure of the GDR, Global Repertoire Database, so I am using the term Registry or Archive instead.) The archive could be a multilayered blockchain or specialist block chains one for music, one for film, art, an academic thesis etc.etc but that are all searchable with one search engine, but stored separately. The block chain could contain only a sign post where to point to the displayed IP containing the actual file. Like youTube is a massive archive of IP, 300,000 uploads per minute!!!!! We need a way of making a NEW youTube (NewTube, this name is taken but for this demonstration I will use it) where the date/time stamp on the upload to official NewTube could be set in stone and not be untampered with/hacked, so the block chain could link to the url on NewTube.
It could also point to the place where the full list of credits is stored in an IMDB type database, which is again verified by mechanisms of ID and trust mechanisms.

3) Authenticate works as original by comparing with what is already in 'NewTube' much like youTube Content ID does today.

4) DO NOT LET GOOGLE control 'NewTube'! It must be for the people by the people! Like Wipo or the Library of congress on steroids!

5) Search engines can build on top to create smart contracts for automated sale and licensing. Giving a commission on sales to fund the Registry/archive.

6) payment mechanism one click licensing offering various methods of payment.
'units' on your phone bill or ISP bill
direct micro money payments via Pay Pal, Apple Pay, Google Pay , Mobile pay or even credit cards if it can be made more easy and secure using a system of password and pass code which you enter 4 different digits out of 8 to make fraud more tricky etc etc

NewTube will need bootstrapping, so needs startup finance and also needs to sustain itself. But a conventional tax on royalties is typically regressive so would need careful design to limit defection by high and low earners. There are people who could help
design such a system.

I also fundamentally believe that we will reach the singularity within 20 years and that this is an important time of transition into AI dominance and that how we programme the AI is very important. So by creating a system that respects humans teaches us and the AI to have a moral and humane conscience that I hope will be our salvation.

Jonathan Harvey-Buschel The blockchain as a data structure is an extremely inefficient use of computational resources when run in a P2P network like Bitcoin. Efficiency here is sacrificed for other properties like censorship resistance. If your system need not be trustless or hard to censor, using a blockchain is very likely not the optimal structure for a solution.

Shilpi Kumar We recently authored a piece on the SPACE framework and what needs to be considered to fully unlock the economic value in the physical-digital network bridge: http://filament.com/assets/downloads/Filament%20Foundations.pdf
Tarique Bhuiyan Pls do refer to a few of my recent past blogs here:


Ravi Variar There is a great opportunity to introduce standardization of various protocols emerging in this space. It will be important to utilize and create such working groups to ensure that both Regulators and User communities have a proper buy in. We have seen the volatility in Bitcoin themes like this can create concerns for regulators which need to be overcome.

Haiyang DING It would be nice if there could be any discussion on [Hyperledger] (https://github.com/hyperledger/hyperledger).
Gilles Gravier Usability above all.

Poon Joseph I want to come to the workshop! :D
Geater Jon I think I'm already invited as I submitted a joint position paper with Marta Piekarska summarizing our joint WG output at the ID2020 workshop. But I thought I'd come through the 'front door' too.
Peter Salvitti
Jae Kwon It's important to note that different blockchain applications may require different architectures. For example, the GnuClear hub is optimized for a scalable token system. But different applications live in various layers, whether they be lightning networks, virtual-machines, exchanges, etc. Thus the importance of mapping things out.

Mike Warner I met Jeff briefly in Boston a few weeks ago. I appreciate the chance to get my team exposed to your workgroup. We can be listeners or active participants as the progress unfolds and the needs arise.
Victoria Lemieux I've recently written this paper on the question of blockchain for record keeping, which represents some early thinking on the topic: http://www.emeraldinsight.com/doi/pdfplus/10.1108/RMJ-12-2015-0042. As I delve more deeply into the technical details of the technology I am looking for ways to develop architectures and design applications to address record keeping challenges.
Darrell Duane
Ethan Buchman I think the major standardization opportunities are in cryptographic verification (ie. smart signatures) and in the interface between consensus protocols and their applications (ie. like Tendermint's TMSP: https://github.com/tendermint/tmsp)
Allan Third https://www.w3.org/2016/04/blockchain-workshop/interest/third.html
Martin Kurze My Position (not necessarily DT's position):
While the World-Wide-Web is a service running on the internet with (basically) no central administration and no built-in privacy (or accountability), the telco industry is built on top of very powerful accounting capabilities: Telcos usually know (or at least can know) their users and the respective usage contexts. They use this knowledge to do "AAA" (Authentication, Authorization, Accounting) which is the telco business' core competence.
This results in many business opportunities and use cases where similar properties are required. In the Blockchain context, I want to highlight two of those properties with an (assumed) synergy potential:
Reputation and
Provable ledger transaction history
Both are currently implemented (or inherently included) in telco business models and technical product portfolios. Both can be disruptively replaced or positively enhanced by Blockchain technology.

To further strengthen telco companies (at least the modern and agile ones) and to make Blockchain based models a success story for the end user, a strong and independant standardization force is needed. W3C and the web community can drive this standardization of Blockchain technology, infrastructure and means of operation.
Web and telco capabilities perfectly complement each other. In some cases the approaches of the "open web" and the "anonymous internet user" seem to contradict the very much regulated and controlled word of the telco industry and also with the need for trust, be it immaterial (= reputation) or material (e.g. financial).
End users as well as industries and businesses rely on these types of trust (and try to build both of them).
End users tend to request contradictory features, or they have different goals in different situations/times. E.g. a user might want to pay for a service anonymously but he wants to prove certain claims in different situations. And sometimes he might want to act anonymously and later on decide that disclosing and proving his identity might be desired.
Businesses (including personal businesses) request a transaction safe system that allows fast and reliable transactions that can be audited and proven if necessary.
Blockchains may help to combine all the different requirements and approaches. I suggest to address two of those in parallel and thus cover two "opposite ends" of the spectrum of blockchain uses cases:
Provide provable reputation (and reputation history) in three flavours based the same blockchain: anonymous, pseudonymous and personalized (optionally also applicable for small and medium enterprises).
Provide provable transaction history with no dedicated and permanently accessible "trust center/certification authority", but based on a "company-issued" blockchain where the company could be a trusted high-reputation telco.
The web and the W3C would play an essential role in both use cases, providing the open and standardized infrastructure and building on top of the numerous previous experiences with open, user-oriented yet industry friendly standards and practices.
This workshop should give all of us (telcos, W3C, end users) a clearer view on the opportunities and probabilities of success for collaborative approaches like this.
