Exa will create the world's first evolving blockchain, ecosystem, and transfer protocol Layer 0 Hyper Graph Transfer Protocol (HGTP) Exa will build the foundational layer of the decentralized web, supporting other layers by providing infrastructure and cross-chain interoperability. Thus solving the blockchain trilemma
Layer 1 Exa Blockchain Properties:
fixed size nodes, such as 22kb
non permanent data storage, data will be reset after reaching certain timelines
directed acyclic graph (DAG), data only flows in a certain direction and never repeats, or cycles
wallets both cold (hardware) and hot (software) can tell when a sending address is valid or invalid
Consensus Protocol Proof of Loyalty (POL) is a new consensus algorithm that rewards users based on loyalty. Streamers will act as nodes, in which when the streamer goes live, they and viewers will validate the blockchain based on the number of hours they stream, and the amount of watchtime from viewers
Layer 2 Zero Knowledge Proofs
non consensus node needs 5 pieces of information
verification key
protocol state
zk proof
account information
merkle path
3 components:
key generation
proof generation
verification
3 fundamental properties:
completeness
soundness
zero knowledge
Elliptic Curve Cryptography for security
uses twin key structure
public and private key for encryption and decryption of data
uses recursion
use cases: digital identity, financial privacy, scalability, zk-apps (smart contracts), zk-bridges, blocks front running
must be non-interactive for blockchain use
Different types of zk-proofs
zk-snarks, zero-knowledge succinct non-interactive argument of knowledge (no information leak, proofs are small and easy to verify, no back and forth communication, proof is the source of truth, the proof is the return output of a function, minimal computing power)
zk-starks
zk- rollups
