Glossary

A

Address A unique alphanumeric identifier representing a user or entity on the blockchain, derived from a cryptographic public key. Used to send/receive transactions and interact with VIDAs.

B

Blockchain as a Data Layer A design where PWR Chain serves as an immutable ledger for VIDAs, treating transactions like rows in a global, verifiable database.

Byzantine Fault Tolerance (BFT) A consensus mechanism (enhanced in PWR Chain) that ensures network agreement even if some nodes act maliciously or fail.

C

Conduit Nodes Specialized nodes that enable trustless communication between VIDAs or between VIDAs and external systems (e.g., cross-chain protocols). They validate and relay transactions, governed by VIDA-specific rules.

Cross-Validation A security mechanism where multiple Execution Agents of a stateful VIDA compare root hashes to detect discrepancies and ensure consistency.

F

Falcon Signatures A post-quantum cryptographic signature scheme (NIST-standardized) used by PWR Chain to secure transactions and validator votes.

H

Horizontal Scalability The ability to add unlimited VIDAs without impacting PWR Chain’s performance, achieved by offloading execution to independent VIDAs.

I

Immutable Records Transactions permanently recorded on PWR Chain that cannot be altered or deleted.

Instant Finality A feature of PWR Chain’s consensus where blocks are finalized irreversibly within seconds.

O

Open Verification The ability for anyone to rerun a VIDA using on-chain transactions to independently verify its state or outputs.

P

Parallelized Processing A scalability feature of PWR Chain where transactions are verified across multiple CPU cores, enabling high throughput (e.g., 600k+ TPS).

Post-Quantum Cryptography Cryptographic algorithms (e.g., Falcon) resistant to attacks from quantum computers, used to secure PWR Chain.

PWR Coin The native cryptocurrency of PWR Chain, used for staking, governance, transaction fees, and incentivizing network participants.

R

Replayability The ability to recreate an VIDA's state by reprocessing its transaction history from PWR Chain, ensuring transparency and auditability.

Root Hash A cryptographic summary (e.g., Merkle root) of an VIDA's state, published on-chain for cross-validation and consistency checks.

RPC Node A Remote Procedure Call node that processes blockchain requests, enabling VIDA's to interact with PWR Chain.

S

Staking Slashing A penalty mechanism where validators or Conduit Nodes lose staked PWR Coin for malicious actions (e.g., double-signing).

T

Tendermint Consensus A BFT consensus protocol modified by PWR Chain for quantum resistance and equal validator opportunities.

V

VIDA Execution Instance A VIDA actively running on a machine, processing its logic and transactions sent to it through PWR Chain.

W

Wallet A tool to manage private keys, sign transactions, and interact with PWR Chain. Types include hot (online) and cold (offline) wallets.

PreviousIf an VIDA’s Logic Changes, how does PWR Chain Ensure Past Transactions Remain Verifiable?
