The Upcoming “Decentralized Cloud” (DPaaS): Decentralized Computing + DB + Storage as a Service

April 24, 2018
I had a talk at a blockchain conference regarding the upcoming public “Decentralized Cloud” systems, which will combine the best of the public cloud platforms (like AWS, Azure, Google Cloud, Heroku, …) with the blockchain and peer-to-peer networks (Ethereum, IPFS, EOS, TRON, NEM, NEO, Storj, Sia, …). Why? Because the trend towards decentralized organizations (DAO)

Blockchain Cryptography for Developers: ECC, secp256k1, SCrypt, AES, Wallets

April 15, 2018
Recently I had a talk about the basics of cryptography for blockchain developers at the Bulgarian Web Summit 2018. I am happy to succeed to introduce the most important concepts of the elliptic curve cryptography (ECC), key derivation and encryption (SCrypt, AES and HMAC), digital signatures (ECDSA, sign / verify) and crypto-wallets (HD wallets, mnemonics

Алгоритми за децентрализиран консенсус – Наков @ jProfessionals (Jan 2018)

January 28, 2018
Шервам видео и материали от моето вчерашното участие на конференцията jProfessionals – Jan 2018. Разказах за предизвикателствата, които съвременните блокчейн мрежи решават, за да постигнат децентрализиран консенсус относно състоянието на данните в блокчейн мрежата, което отделните възли виждат. Обясних защо е необходим консенсус, как консенсус алгоритмите подреждат транзакциите и построяват новите блокове, как решават double-spending
