What's the technology behind StarkNet?

StarkNet enhances Ethereum's scalability by leveraging an ingenious cryptographic technique known as zk-STARKs, functioning as a secondary protocol layer.

Delving into zk-STARKs, these are a form of cryptographic proof pioneered by StarkWare, crucial for ensuring secure and private computation on blockchain platforms. They operate by shifting intricate computations to an external STARK prover, which then formulates cryptographic proofs. Subsequently, a STARK verifier on the blockchain validates these proofs, certifying the computations' accuracy.

StarkWare has ingeniously merged contemporary algebra with robust hash functions to optimize zk-STARKs. The company has made remarkable progress in complex proofs, such as quasi-linear probabilistically checkable proofs (PCPs), interactive oracle proofs (IOPs), and efficient algebraic coding protocols like FRI, positioning their STARK prover and verifier as the swiftest available, surpassing other cryptographic methods. Notably, this technology is constructed on minimal and more secure cryptographic assumptions, offering quantum resistance, transparency, and a setup free from cryptographic snares and hidden flaws.

StarkNet's infrastructure provides an effective and economical environment for smart contract execution, comprising several key components:

ZK Operator: This entity is adept at crafting ZK proofs for transactions, orchestrating the Merkle tree data structure that facilitates proof creation, ensuring accuracy and trustworthiness in the proofs.
Execution Manager (EM): The EM orchestrates the network's symphony, overseeing smart contract execution and managing transactions, updating the network's state with each transaction to maintain seamless operations.
Verifier: Serving as the scrutinizer of authenticity, the verifier confirms the ZK proofs' validity, essential for the integrity and precision of contract executions, guaranteeing legitimacy.
Cairo Programming Language: StarkNet was constructed using Cairo, a language tailored for zk-STARKs, enabling the creation of intricate and secure smart contracts, with a framework that supports local contract testing prior to network deployment.
Proof Verifier Factory: This facility churns out verifiers as necessary, handling their creation and lifecycle, ensuring the system can validate processes effectively.
Storage: At its core, StarkNet features a storage layer utilizing a Merkle tree structure for efficient contract and data retrieval, expediting smart contract interactions.
Gateway: This bridge connects Ethereum and StarkNet, facilitating the transfer of funds, providing a seamless transition of assets between the two platforms, and allowing users to tap into StarkNet's benefits.

Through the implementation of zk-STARKs, StarkNet attains scalability by enabling off-chain computation alongside on-chain verification, reinforcing the secure and private execution of blockchain computations. The foundational technologies of StarkNet, like Cairo, along with its STARK prover and verifiers, have withstood the rigors of real-world application, proving their efficiency and dependability.

What is the native explorer for StarkNet?

StarkNet's ecosystem is equipped with essential tools for transparency and user engagement, notably its block explorers, Voyager and StarkScan.
