EEA Virtual Event

In the middle of the COVID-19 pandemic the EEA events are not happening physically in New York City, that is why today it took place the First Ever Virtual Event.

It was a half-day event to explore blockchain applications, technical insights, reference architectures, and practical business use cases. Our teams connected remotely from New York, Buenos Aires and Montevideo.

The content of the event covered everything from the state of Ethereum in the enterprise to the growing use of the Ethereum Mainnet for business process automation.

The topics included among others:

  • The State of Enterprise Ethereum Adoption
  • Use Cases Built on Ethereum Mainnet
  • Baseline Protocol
  • Ethereum Adoption Tracks
  • The Enterprise Blockchain Technology Stack and Roadmap
  • Ethereum in Finance
  • Community: Through the Lens of the Ethereum Foundation
  • Blockchain for Social Impact

Speakers from many global companies included Banco Santander, BP, EY, Microsoft, JP Morgan, Ethereum Foundation, ConsenSys, Chainlink, Unibright, Fnality, Envision Blockchain Solutions, PegaSys, Provide Technologies and LimeChain.

The networking platform worked very well and we had the opportunity to interact and meet colleagues in the community.


ZirconTech team has been working for several years with the Ethereum platform, and has been keeping up to date with enterprise customer demands by developing competencies and implementing projects in Quorum and Hyperledger Besu.

Quorum is a platform developed by J.P. Morgan through its Blockchain Center of Excellence, leading efforts for Distributed Ledger Technology applications. It is an enterprise blockchain platform, a fork of the public Ethereum client ‘geth’ with several protocol level enhancements to support business needs. The primary purpose of the Quorum project was to develop an enterprise Ethereum client which empowers businesses to embrace and benefit from blockchain technology.

Hyperledger Besu is an open-source Ethereum client developed under the Apache 2.0 license and written in Java. It runs on the Ethereum public network, private networks, and test networks such as Rinkeby, Ropsten, and Görli. Besu implements Proof of Work (Ethash) and Proof of Authority (IBFT 2.0 and Clique) consensus mechanisms.

The welcome of the event to the state of Enterprise Ethereum Adoption was from John Whelan, (Banco Santander) and Yorke Rhodes III (Microsoft). John highlighted the 5th birthday of Ethereum Mainnet as the day of the event. He is the Chairman of the board of EEA, and te Managing Director of Digital Investment Innovation at Banco Santander.

Maria Concepcion (Coty) de Monteverde, from Banco Santander spoke about Finance applications, the Digital Bonds issuance on the Ethereum Mainnet. She is the Blockchain Center of Excellence Director in Santander, and is a Board Member at the Alastria Blockchain Ecosystem.

More finance applications with Ethereuem came from Christine Moy (J.P. Morgan), Artem Korenyuk (DTCC); Valerie Dahiya (Perkins Coie LLP) and Adam Clarke (Fnality).

Vanessa Grellet from ConsenSys addressed the topic of Blockchain for Social Impact, talking about Payments and Financial Inclusion.

Earlier on July 8th, the Enterprise Ethereum Alliance announced the appointment of Dr. Daniel Burnett as Executive Director, who was instrumental in the rollout of the Baseline Protocol, and is a former PegaSys Blockchain Standards Architect. During the event, EEA Chairman John Whelan hosted a fireside chat with Daniel “Dan” Burnett. Dan will serve as a catalyst for the EEA’s growth by identifying ways to accelerate the pace of Ethereum innovation and adoption.


This month was also published some key ecosystem results like the Ethereum Mainnet Use Case Analysis v1. The EEA published the first analysis in a series of reports focused on the current state of the Ethereum ecosystem and utilization of the Ethereum public blockchain (Mainnet) –

2020 has been a year of remarkable enterprise Ethereum advances from the Baseline Protocol to enterprise Mainnet use cases in automation, business integration, finance, supply chain, and sustainability-focused carbon accounting efforts”. Daniel Norkin at Envision Blockchain and Tas Dienes at the Ethereum Foundation worked in tha analysis. The insights play a key role to Ethereum adoption and utilization. Stefan Schmidt at Unibright, Mark Caraway at BlockApps, and John Wolpert at ConsenSys also provided valuable contributions to this report.

Monax Acuerdo de Servicios Profesionales Smart Contracts Legaltech

ZirconTech facilita la contratación digital con la plataforma Monax y la Red de Acuerdos.

https://www.zircon.tech/blog/2019/02/02/zircon-tech-works-with-monax-technology-for-the-legal-industry-using-blockchain/

Zircon Tech está trabajando con Monax, con sede en el Reino Unido, con el objetivo de incorporar la tecnología blockchain en el sector legal. Como resultado de esta relación, ZirconTech ha podido mostrar cómo se facilita la contratación digital con la plataforma Monax (https://monax.io) y la Red de acuerdos (https://agreements.network/). Los abogados no necesitan aprender lenguajes de programación como Solidity para ejecutar contratos inteligentes. Con Monax y su herramienta BPM (Business Process Model) se puede ir directamente al negocio para resolver problemas reales. Estamos descubriendo que la ejecución de acuerdos simples de servicios profesionales a través de contratos inteligentes se está convirtiendo en un caso de uso líder para la tecnología blockchain.

Contratos inteligentes y pagos

Un componente interesante de un contrato digital para servicios profesionales es el proceso de pago. Si bien podría implementarse manualmente y agregar el documento de pago a la cadena de bloques, si hablamos de contratos inteligentes que se ejecutan por sí mismos, ¿por qué no ejecutar automáticamente el pago cuando ha llegado el momento de acuerdo con las reglas del contrato? Este tema ha sido un área de trabajo de ZirconTech en varios países y particularmente en Chile. Durante el año hemos estado evaluando con diferentes instituciones de servicios financieros y nuevas empresas, para analizar cómo aprovechar la tecnología existente para implementar estas soluciones y qué se necesitaría para facilitarlo en el futuro. Se están implementando varias pruebas de conceptos.

Bienes Raíces

Los bienes raíces también están despegando. La contratación digital con Monax también es una alternativa para abordar varios procesos y ZirconTech está explorando formas de usar la tecnología. (https://monax.io/blog/2019/07/18/blockchain-use-in-real-estate/)

Como menciona el CEO de Monax, Casey Kuhlman, “blockchain tiene la capacidad de tomar la secuencia de inversión inmobiliaria y simularla. Esto puede crear una propiedad parcial y aumentar significativamente la liquidez. Blockchain también puede abrir fideicomisos de inversión inmobiliaria (REIT) a una nueva serie de inversores”.

“Por lo general, el sector inmobiliario es una clase de activos que requiere un capital significativo y está dominado por individuos de alto patrimonio. La tokenización permite la reducción en la cantidad de capital que cualquier individuo necesitaría, lo que significa que más personas tendrían la oportunidad de invertir. Esto ayudaría a diversificar las carteras. También ofrecería más liquidez en el ecosistema y la oportunidad de mover activos más fácilmente “

Propiedad intelectual, servicios financieros, contratos de trabajo

La contratación digital es otra área de trabajo en Argentina. ZirconTech ha estado asesorando a abogados sobre las ventajas de trabajar con tecnologías como Monax. De esta manera, se están desarrollando varios casos interesantes con oficinas legales innovadoras, particularmente en la gestión de la propiedad intelectual.

En Colombia se han presentado servicios financieros y soluciones tecnológicas legales a varias compañías de los sectores bancario y legal, y servicios de outsourcing. El Blockchain Center de Colombia está recibiendo mucha tracción y está muy conectado con todas las tecnologías de la 4ta Revolución Industrial.

Por el lado de Uruguay, ZirconTech ha sido pionero en el uso de la tecnología Monax en vivo con funcionalidades de “acuerdos rápidos” para lanzar contratos laborales y de servicio con sus colaboradores. Esta tecnología se ampliará y se está trabajando con un grupo legal local, con abogados especializados para crear contratos más complejos para contratos laborales y servicios profesionales, incluidos los mecanismos de pagos automáticos. Estamos haciendo un esfuerzo conjunto con Monax y el equipo legal ha viajado a Nueva York para reunirse directamente con los desarrolladores de la Red de acuerdos.

The second EEA NYC Meetup took place at Fordham University McNally Amphitheatre, 140 West 62nd Street New York. The meeting explored how blockchain technology is being used to increasingly automate legal agreements, issues related to enforceability of smart contracts, machine-to-machine contracting, and whether existing laws like the E-Sign Act, ESRA and UETA are sufficient to address enforceability concerns.

The event was moderated by Vanessa Grellet, Executive Director of Strategy, Enterprise & Social Impact at ConsenSys.

Blockchain technology is useful for more than just simply digital currencies like Ether and Bitcoin. Relying on a blockchain, parties can also deploy autonomous smart contract programs, which can be used to model all or parts of formal legal agreements.

These topics were addressed by Stuart D. Levi, co-head of Skadden’s Intellectual Property and Technology Group; David M. Adlerstein, counsel in the Corporate Department at Wachtell, Lipton, Rosen & Katz; and Andrea Tinianow, Chief Innovation Officer for Global Kompass Strategies.

Andrea Tinianow conceived and was the founding director of the Delaware Blockchain Initiative which gave rise to the “Blockchain Amendments” to Delaware’s General Corporation Law. These amendments expressly authorize corporations to issue and maintain their stock ledgers on a blockchain. Andrea is a member of the global Wharton RegTech think tank. She is also an advisory board member of the Weinberg Center for Corporate Governance at the University of Delaware. In 2017, MarketsMedia awarded Andrea its “Women in Finance Award” for Excellence in Blockchain.

ZirconTech has started a process of evaluation and testing all emerging blockchain based legal technologies, and this was again another great opportunity to interact with the key global lines of development.

Later was the case of Amberdata demonstration, where they showcased the product. Amberdata commented about the customer pain points and argued that everyone needs transparency into the state and health of blockchain infrastructure, applications and transactions. That means no operational instrumentation, no monitoring, alerting, search or insights, and no visibility into scalability, availability and throughput. There are unique challenges operating decentralized.

Trail of Bits discussed the case Manticore, the smart contract analysis. It uses symbolic execution of EVM to deeply explore possible contract states across multiple transactions and contracts. It discovers functions directly from bytecode, detects contracts flaws like int overflows, uninitialized memory and storage usage, among other features. It also verifies customized program assertions. Manticore is open source and can be found at https://github.com/trailofbits/manticore

As a second initiative, Trail of Bits introduced Echidna, a smart contract testing solution. It uses fuzzing and input generation to generate and execute many contract inputs and generate intelligent grammar based inputs. Echidna seamlessly integrates into developer workflows, runs thousands of generated inputs per second, and reduce test cases for easier manual analysis.

Mark Mossberg, Security Engineer in Trail of Bits

Mark Mossberg, a Security Engineer in Trail of Bits, recommended the following steps if you are developing a smart contract:

  • Review Not so Smart Contracts
    • Trail of Bits database of insecure Solidity code
    • Ensure your team learns from others mistakes
  • Run Slither on every new code checkin
    • Static analyzed/bug checker for Solidity
  • Write Echidna tests for new features
    • Solidity smart fuzzer/testing framework
    • Aim for 80% coverage or higher
  • Run Manticore for final verification
    • EVM analysis and verification tool
    • Discover any dangerous, obscure states

Alethio introduced its platform to capture and synthesize block data in real-time, presenting relevant information via clear and accessible dashboards. It uses data science & semantic modeling so users can clearly see what matters to them. Includes features like advanced block explorer, intuitive user interface, meaningful visualizations, real-time alerting, account timelines and smart contract analytics.

It took place the first EEA NYC Meetup at Fordham University McNally Amphitheatre, 140 West 62nd Street New York. A brief update on the exciting things happening at EEA (Enterprise Ethereum Alliance) and working demos of products from members showcasing the results of the alliance’s work.

The event was moderated by Vanessa Grellet, Executive Director of Strategy, Enterprise & Social Impact at ConsenSys.

J.P. Morgan and Zcash publicly showcased for the first time the latest version of Quorum. The new features included the Zero-knowledge Security Layer that allows for cryptographically assured private settlement of digitized assets on Quorum.

ConsenSys introduced OpenLaw, demonstrating tools to begin managing large and complex legal transactions on a blockchain. OpenLaw showed how you can execute multiple legal agreements using blockchain technology and trigger the execution of multiple smart contracts, including smart contracts to transfer ether every minute and to transfer tokenized stock on a vesting schedule. ZirconTech is evaluating all emerging blockchain based legal technologies, and this was a great opportunity to interact with one of the key global lines of development.

The we had the opportunity to see Datarella, which developed for the United Nations World Food Programme an Ethereum based asset management and payment system to distribute aids. The system has been in use in the field for half a year. Building and deploying real-world applications shows us how important it is to push the blockchain to enterprise maturity.

Then we had more from the Brooklyn based ConsenSys, in this case they presented an overview of the user-centric uPort identity system and how it is currently being used today by ConsenSys Academy and governments around the world for projects, such as government attestations and document notarization. TuPort showcased functionalities like the ability to sign Ethereum transactions, manage attestations, and sign documents.

Finally, presented by TruSet’s Co-Founders, Tim Rice and Will Janensch, a demo showcased how member nodes can publish, validate, reach consensus, and consume a bond reference data record on the Ethereum blockchain.
