Day 3 DevCon4 (2018) , Prague
Half of the event has already gone.. Let’s try to get the most of of these days
- Preparing for a security audit. We expected quite more of this 2 hours workshop. Half of the time was focused on how to build a solidity contract… the other half was centered on what do they care about, look at, review as security auditors audit. Minimum 90% of coverage,Non Spaghetti code, up to date libraries, symbolic execution, functional completeness and testing approach that has sense and is understandable
Some food , networking, and a meeting with the PEGASYS guys. We shared out needs on IBFT, needs : smart contract based permissioning, stable performance, whitelists, firewall etc. They are really working hard and with a real community based focus development
- Web3 Design Systems — components and design standards for better dApp UX. A good overview about the challenges on developing dapps towards UX design. Its at important that we find a way to on onboard non-crypto oriented users with really cool apps. There are only 13000 active user on the overall space.
Networking brings you ideas, information: Shamir keys as key recovery system, quorum by consensys, Shared docker including chain and deployed contract version
- How to make smart contracts upgradable without adding trust?. We spent 45 mins on a 2 hours workshop centered on upgradeable contracts. A common proxy storage approach splitting storage, including a new versioning concept that’s really interesting
- Oracle = Chainlink , middleware, oracle
Chainlink brings a platform for oracles to build your external needs. They have asSWIFT and VISA agreement. Quite generic presentation. The official web page has common info. A project to follow and check how they include payment information and differences with oraclize.
- Using Solidity’s SMTChecker. SMT checker a formal proof verification framework.
As EVENTEUM commiters, abridge between your Ethereum smart contract events and backend microservices, it was fun to meet Kauri guys (some dubai mates) and know who is behind de scenes of the github repo.
Day 3 ends and there are some parties around. Blockchains LLC is doing a lot of noise and we decided to go to the party, perhaps it seems quite a strange marketing strategy. 10 free buses to the event… we arrive, drinks , sushi, waffles, ice cream, nice stewards and people with bodyguards…place and a mood quite opposite to devcon DNA. Countdown finishes and the speech starts, hologram, amazing videos… 15 minutes speech of 2 billionaire brothers talking about a smart city in nevada, private key custody bunker, AI, nanotechnology, vains biometry… a sandbox to start… and a final call for developers …and all of this without any drugs , hopefully there weren’t any on the food or drinks. Lets see next news and steps. Seems a mad approach but who knows.
We joined aragon’s party afterwards, drinks, music, fun… thats all for today!
