Digital assets and cryptocurrencies hack is a recurring issue that generated losses worth billions of USD over the last couple of years. Numerous exchanges have been hacked and some of them went bankrupt. With the increasing interest of institutional players including stock exchanges and banks, secure protection of digital assets from external and internal attacks as well as from loss is of the utmost importance. Key takeaways of this talk are • Context and drivers for secure custody of digital assets • How thefts from cryptocurrency exchanges happens ? • Why it is difficult to protect digital assets and cryptocurrencies, risks and mitigation techniques. • Best practices for crypto custody and cryptocurrencies wallet management (BTC, IOTA,ETH,XLM …)]]>

0 Privacy-preserving techniques using zero knowledge proof in public Ethereum /slideshow/privacypreserving-techniques-using-zero-knowledge-proof-in-public-ethereum/81585254 executivesummarybat38elcazkpcryptoblockchain-171104092300
Public Blockchain technology like Ethereum is gaining interest and growing use case among startup and fintechs. Apart from scalability issues which are going to be solved with new consensus and mining techniques (Ethereum Metropolis and Bitcoin SegWit2x with Lightning network), privacy on transaction is still an issue which is not yet fully addressed yet. Because of the public nature of a Ethereum, many businesses are reluctant to deploy Smart-contract or Dapps solutions for fear of exposing confidential or sensitive information. The use of zk SNARKs (zk-SNARK stands for “Zero-Knowledge Succinct Non-Interactive Argument of Knowledge”) would essentially solve this dilemma (next EIP improvement of Ethereum called 'Byzantium' include zk SNARKS). The idea of zk-SNARKs is that they allow verification of the correctness of computations, without a verifier having to execute those computations, or even learn what was actually executed. Using zk-SNARKs, a verifier can confirm that a computation happened correctly, with ‘zero-knowledge’ of the computation. We propose during this talk to have a brief presentation on cryptography and theory around zero-knowledge proof algorithm. Then we will try to showcase the benefits of zk-SNARKS and other privacy-preserving techniques (like zcash) on the public blockchain ecosystem.]]>

Since January 2017, it does not happen a week without a new ICO is launched (more than 200 to date with $ 3Mds raised), but also without an ICO facing attacks of all kinds (Parity Multi-sig wallet bug with $ 30Mln stolen and Scam slack/twitter posts and phishing attacks with DNS spoofing, phishing link ...) During this talk, we will discuss the security principles of an ICO and see how and which elements to protect in order to secure both IT aspects (server hardening, web application firewall, multi-factor ...) and processes aspects (governance, mutli-signature procedure, smart-contract ownership, hot / cold keys storage, secret management ...) Also we will try to give an overview on how to use/secure smart-contract for Token sales and TGE process.]]>
