#blockchainhackers vol.3 recap

Hacken, SmartDec and ChainSecurity hosted #blockchainhackers vol.3 meetup during Berlin Blockchain Week. The best blockchain security engineers shared their knowledge by presenting lightning talks and chatting during the afterparty networking. Hacken team is proud to have 60+ attendees who care about blockchain security and we continue to host our meetups regularly. Thanks Parity for giving us the perfect location for the meetup! 

Kudos to the speakers who brought highest-quality content to #blockchainhackers vol.3: 

• Alexander Seleznev (SmartDec) presented SmartDec Scanner - the tool, which helps enterprises to build secure development process for blockchain projects. Alexander demonstrated how the tool can be used as issue tracker and vulnerabilities management platform, how its UI can be integrated to smart contract security scanners and many more cool features of it!
• Bernhard Mueller and Daniel Luca (MythX / ConsenSys Diligence) presented their talk from DefCon 27 about security audit and exploitation tools for Solidity smart contracts. Bernhard talked about MythX features, for example, symbolic execution. Daniel presented 2 tools for smart contract exploitation tools - Karl and Theo.

• Ben Burns (Whiteblock) talked about Genesis platform - end-to-end development sandbox and testing platform for Web3 and blockchain-based distributed systems. Ben demonstrated main concepts and features of the Genesis platform
• Hubert Ritzdorf (ChainSecurity) presented the security  implications of the upcoming Istanbul hard fork. The main concern of Ethereum security community is EIP-1884 - Opcode repricing for trie-size-dependent opcodes. Implementation of EIP-1884 might break a lot of working contracts and no solution is found for the issue. If you have any ideas how to implement EIP-1884 without impact on existing contracts - refer to contacts below

• Liz Steininger (LeastAuthority) demonstrated ideas how to make the security reports more understandable for users. Liz showed several consumer report examples, which might help to understand how to make more user-friendly reports and outlined call to actions 

• Pavel Radchuk (Hacken) talked about low-hanging fruits in blockchain security. Pavel demonstrated blockchain vulnerabilities that are easiest to test against and several real-life examples, for example, blockchain network DoS via API and RCE in block explorer of the EOS testnet

#blockchainhackers vol.3 meetup is THE THIRD event of the series. Hacken will continue gathering blockchain security experts and everyone interested in security.
