On March 5, 6 and 7, part of the team of iobuilders Marcos Serradilla Díez, Miguel Gómez Cuesta, Javier Cosío Álvarez, Fernando Paris and Iván Saiz de Castro traveled to Paris to attend the Ethereum Community Conference 2019 (ETHCC 2019) with great enthusiasm.

For those who do not know, it is one of the most outstanding events among the Ethereum community and this year celebrated its second edition.

At the Ethereum Community Conference 2019 we had the opportunity to attend many speakers and workshops from the entire international community.

It would be impossible to summarize everything that we experienced because the event had a multitude of options with different themes such as scalability, finances … and no less than more than 250 speakers!

EthCC 2019 featured the usual topics like ICO, DAO, Tokens or Scalability but also a From Zero to Hero track dedicated to people that want to learn how Ethereum works. Others covered challenges concerning regulations and cryptoeconomics.

In addition, there was a week full of Ethereum events from the 4th to the 10th! Other events such as Ethereum magicians council, meetups, demos, workshop and hackathon series. You can check the complete agenda in blockchainweek.fr.

Decentralised Finance

Many projects are focusing on finance applications, while maintaining a decentralised governance system.

Some of topics in these talks were regulations, security tokens, stable coins, other alternative networks like Liquidity, framework for financial apps like Katallasos.

Technology

One of main issues with Ethereum is that smart contracts were never designed to interact with the Internet outside the Blockchain, never mind the physical world. Several projects were proposing methods to bridge this gap and allow communication and exchange data between smart contracts and the rest of the Internet.

Oraclize and Chainlink is creating proxies that can act as oracles in order to provide data to smart contracts. Both these solutions are of course off-chain.

Wallets

Argent wallet is a new crypto asset wallet, but one which behaves very closely to a bank account.

The crypto assets are kept within a smart contract, and a “guardian” is able, through signatures to interact with the smart contract, to limit spending or to an issues with Ethereum is that smart contracts were never designed to interact with the Internet outside the Blockchain, never mind the physical world.

Several projects were proposing methods to bridge this gap and allow communication and exchange data between smart contracts and the rest of the Internet. Oraclize and Chainlink are creating proxies that can act as oracles in order to provide data to smart contracts. Both these solutions are of course off-chain. Prevent certain transactions from going through. Such a system can be useful for beginners who may want to have a wallet with the same protections as their traditional bank account.

Gnosis safe is secure wallet with 2 factor authentication. It is usable and accesible for both new and advanced users. The large trade-oofs between security and usability are usually reduced.

Decentralised services / storage

Building decentralised protocols on centralized services might soon be a thing of the past. Pando is building a decentralised Github, leveraging technologies such as IPFS, Swarm and Aragon in order to rely exclusively on decentralised technologies for storage and governance.

Governance / DAOs

Governance was a hot topic too like the broad talk about blockchain governance on a macroscopic level by lead researcher Vlad Zamfir. Panvala wraps the existing ecosystem of grant funders, corporate open source projects and volunteers with a token that gives them all a shared incentive to find sustainable funding together.

Dai ecosystem

POA Network presented the characteristics of the first stable chain using bridged Dai — xDai- as the native asset. The chain is indeed less secure than public blockchains but very well suited to allow a large number of transactions with very low fees and confirmation times.

MarkerDAO is an open platform that allows equal access to high quality financial services, including fair credit for everyone.

Dai is an asset-backed, hard currency for the 21st century. The first decentralized stablecoin on the Ethereum blockchain.

Privacy

On the other hand, upgrading users confidentiality and private data management on public networks was also an important topic.

AZTEC protocol teams make use of zero-knowledge proofs and in particular zk-SNARKs in their protocol.

InTech devs are making their way into allowing the use of private transactions through the Parity client.

HOPR offers a solution by establishing P2P communication between nodes. Following another path to privacy. Their protocol encrypts the message, besides making it hard to know who is sending that message, the size of the message, and the IP addresses involved.

Security tokens

Tokenization of financial assets is a thing, and projects like Polymath, Meridio, and Dauriel Network are at the forefront of it. Dauriel Network allows the issuance, management and transfer of compatible securities on Ethereum blockchains, both public and private.

The organization of the event was been very good and more than 1000 people from all over the world participated. Many coffees an interesting conversations shared with nice people in a unique atmosphere.

But not all was conferences or workshops, we had the opportunity to talk with some of the developers with whom we collaborated on open source software projects. For example, we spoke with our friends from Kauri (Consensys) with whom we collaborated in the Eventum project.

We also had the opportunity to talk with people from other companies about what we are doing in ioBuilders and about our ioCash platform that allows us to operate with blockchain regulated money as a stable 100% regulated bank, receiving feedback and a great interest from the community .

If you still do not know our platform do not hesitate to visit the product website (we have a demo dApp called Eurion available).

In short, we come with re-energized and with great enthusiasm in what we are doing.

The future is here! Let’s #build it!
