9 results for “oracle”

  1. Glossary termOracleA system that delivers outside data, most often asset prices, to a blockchain so that smart contracts can rely on it.
  2. ArticleOracles: how outside data reaches the blockchain and where it breaksA smart contract cannot look up an asset's price on its own. We explain how oracles deliver outside data to the blockchain, how their architectures differ and what failures and manipulation they face.
  3. SectionTechnology and infrastructureHow the mechanisms behind crypto applications work: price discovery, oracles, on-chain settlement, layer 2 networks and the line between on-chain and off-chain.
  4. ArticleWhy crypto infrastructure combines on-chain and off-chain componentsWhy trading protocols do not move everything onto the blockchain, which functions usually run on servers and which in smart contracts, and how to locate the trust boundary — using Variational’s documentation as an example.
  5. ArticleDeFi protocol risks: from smart contracts to counterpartiesThe classes of risk that make up the overall risk of a decentralized finance protocol, where each one arises and why a code audit covers only part of the picture.
  6. ArticleProtocol and application: how Variational and Omni relateWhere the Variational protocol ends and the Omni application begins: what settlement pools define, what Omni decides, what OLP is, where revenue comes from and how this split affects risk.
  7. Glossary termLiquidationThe forced closing of a position, or part of it, when collateral falls below the maintenance margin level.
  8. ArticleWhat happens in on-chain settlement: a trade's path from quote to ledgerHow settlement differs from clearing and booking, what actually makes it “on-chain” and which parts of the process can be verified on the blockchain and which cannot.
  9. ArticleWhy crypto applications use layer 2: the Arbitrum exampleWhy applications move transactions to layer 2 networks, how an optimistic rollup works and what trust assumptions come with a sequencer and upgradeable contracts.
