Design Overview
Pyth is a protocol that allows market participants to publish pricing information on-chain for others to use. The protocol is an interaction between three parties:
  1. 1.
    Publishers submit pricing information to Pyth's on-chain program. Pyth has multiple data publishers for every product to improve the accuracy and robustness of the system.
  2. 2.
    Pyth's on-chain program combines publishers' data to produce a single aggregate price and confidence interval.
  3. 3.
    Consumers read the price information produced by the on-chain program.
The Pyth program maintains a number of different Solana accounts that list the products on Pyth and their current price data. Publishers publish their price and confidence by interacting with the on-chain program on every slot. The program stores this information in its accounts. The first price update in a slot additionally triggers price aggregation, which combines the price data from the previous slot into a single aggregate price and confidence interval. This aggregate price is written to the Solana account where it is readable by other on- and off-chain programs (see Client Libraries for how to use this data).
