BlockWorld 2018

Blockchain alone isn’t enough to provide true cybersecurity — but add it to trusted computing, and you’ve got a powerful combination that keeps an immutable record of what you’re doing while ensuring that it’s what you wanted to do.

In this talk the speaker will explain very briefly the key cryptographic concepts used in the blockchain systems and will demonstrate them with Python code: - Elliptic curve cryptography (ECC), ECC concepts, curves, secp256k1, ed25519 - From private key to public key to blockchain address - Generating Ethereum addresses / signing / verifying signed messages - Cryptographic hash functions like SHA256, SHA3, RIPEMD160, … - HMAC and key derivation, key-derivation functions like HMAC-SHA256, PBKDF2, SCrypt - Blockchain wallets: simple keystores and HD wallets (BIP39 and BIP44), wallet formats (like JSON / UTC), wallet encryption (AES + padding + CBC/CTR, SCrypt, HMAC)

The shaping of the block chain 3.0 and the use cases about the Dapps in China and US.

NuCypher is a data privacy layer for blockchain and decentralized applications that gives developers a way to store, share, and manage private data on public blockchains. It uses proxy re-encryption to create a decentralized access control infrastructure and is leveraged by leading dApps and protocols like Bluzelle, Origin Protocol, Medibloc, and many others.

Currently the mindset of the IoT world is that devices are clients to a powerful central server. This is not going to work going forward with billions of potentially insecure devices with our personal information communicating over long distances to servers in the cloud. Hopefully the general public will wake up and demand that they own their data, and will be provided with unbrickable future-proofed IoT products. If that happens the end-user will need to be protected with end-to-end encryption, in-house security products to protect the “lesser” devices and will need the ability to source services from independent providers for their needs (security, storage, etc). This will make the service providers in the cloud clients of our devices on the IoT Edge. The whole client-server paradigm will be inverted, central cloud clients communicating with IoT Edge servers. The inversion quickening has already begun! The unbrickable, free open and modular hardware platform, the Subutai Blockchain Router v2.0 went into production in April of 2018 to specifically lead the inversion. It is the Swiss Army Knife of IoT Gateways. The router has an Arduino Shield header, a Raspberry Pi Hat, and 4-PMOD connectors to interoperate with shields offered for these ecosystems. Thousands of sensors, actuators, controllers, and peripheral buses interoperate with the Subutai Blockchain Router. The router is acts both as an IoT Gateway and a hardware accelerated cloud router. It’s essentially a Subutai appliance with custom circuitry inside programmable logic that also supports an advanced hardware security framework for industrial IoT. The device’s FPGA can also contain a soft core for the Ethereum Virtual Machine to rapidly execute EVM instructions. It is designed to integrate itself and the devices it connects on the edge securely into the blockchain. In this session we will introduce users to the Subutai Blockchain Router and how to create IoT-enabled edge using the Subutai Platform.

AnyLog is a decentralized network that manages IoT data. AnyLog uses storage and compute resources offered by miners (for rewards) to create a massively parallel computer to process IoT data. Using a unique and innovative approach (leveraging a decentralized network), AnyLog allows users to store, share, query, and monetize IoT data in real time, with no reliance on a centralized authority.

AnyLog inherently solves the problems of scalability, real time availability and high costs associated with the huge amounts of IoT data and it replaces the IoT silos of data with a global and unified platform. In the same way that Google offers a unified interface to websites' data, AnyLog offers a unified interface to IoT data.
