Next-day Workshop: Introduction to the Ethereum Ecosystem

This is an introductory workshop aimed mostly at developers who have little to no experience with the Ethereum tech stack and are interested in learning how to interact with its blockchain using the available tools. We will show how you can deploy basic smart contracts and how to interact with them, both directly and through dApps(decentralized applications). Everything will take place on the Ropsten testnet. After participating, you’ll have plenty of knowledge that will help you use your own wallet, make transactions with it, participate in ICOs and even trade cute digital pets!
Do all of the above sound completely gibberish but also very interesting to you? Take part in the workshop to find out what the hype is all about.

** Prerequisites **
Adequate understanding of basic computer science and internet concepts are a prerequisite for attending the workshop. Mostly recommended for people with developer experience. You are encouraged to bring your own laptops in order to follow the examples.

** Schedule **
11:30-12:00 Setup and use an Ethereum wallet
12:00-12:30 Create and deploy your own ERC20 token
12:30-13:00 Participating in ICOs
13:00-13:30 Interacting with dApps through Metamask

Agenda:

1st Talk:

Challenges of ML-based solutions for credit risk assessment

End-to-end fully automated machine-learning-based decision engines for credit risk assessment present several challenges. Scientific, engineering, financial, regulatory. In this presentation we will focus mainly on the scientific challenges and we will briefly touch upon some of the engineering ones. What data to collect and how to process them, what machine-learning algorithms to use, how to evaluate the models, how to achieve high performance, how to maintain and monitor the engines in production are a few questions that will be answered. If time permits, we will dive deeper into feature selection and data source evaluation, concept drift and reject inference mitigation, transfer, active and reinforcement learning, growth vs risk trade-off and pricing strategy.

Konstantinos Papakonstantinou (https://www.linkedin.com/in/konstantinospapakonstantinou/) has a proven track record of managing data science teams and developing data products in high-tech and fintech organizations. At Kreditech (https://www.kreditech.com/), he built from ground up and is currently directing the “Data Science Lab”, a team that has prototyped and productionized machine-learning-based solutions for credit risk management, product personalization, customer acquisition and retention. Konstantinos holds a MSc in Electrical Engineering from the University of Southern California and a PhD in Statistical Signal Processing from Telecom ParisTech.

2nd Talk:

Beyond Bitcoin; Blockchain technologies and how they disrupt every industry

Bitcoin proved that open-source software, with open data and open infrastructure, can manage trillions of dollars without a single glitch. In this presentation, we will investigate the technologies behind Bitcoin and Ethereum and we will see how they promise to disrupt every major industry by bringing significant benefits over traditional infrastructure.

Dimitrios Kouzis-Loukas (https://www.linkedin.com/in/lookfwd/) studied Applied Mathematics and Physics in Athens and a decade later ended up designing low-latency distributed infrastructure for financial applications in New York. He enjoys working on challenging, high-impact problems and appreciates simple, elegant and pragmatic solutions.

Καφεδάκι με τα μέλη του Volos Developers

Καφεδάκι με τα μέλη του Volos Developers την Πέμπτη 14 Δεκεμβρίου στο Garden στις 19:00.

Σκοπός της συνάντησης αυτής είναι να πραγματοποιηθεί σε χαλαρό επίπεδο μία συζήτηση σχετικά με την οργάνωση των επόμενων συναντήσεων, με άμεσο στόχο την συνέχιση του project για τα μονοπάτια του Πηλίου. Επίσης, μπορούν να συζητηθούν και άλλα θέματα που αφορούν την κοινότητα όπως είναι για παράδειγμα η πραγματοποίηση ένα hackathon.

One more thing: Όπως πάντα, μετά θα ακολουθήσει brainstorming με μπύρες ή τσίπουρα. 🙂
