Polymarket brings blockchain indexing in-house with rindexer for faster data

Polymarket has moved its primary blockchain indexing infrastructure in-house, cutting the time needed to surface some onchain events by as much as 14 blocks, or roughly 28 seconds. Summary Polymarket has moved its primary blockchain indexing in-house using the Rust-based rindexer tool. The new system can surface onchain events up to 14 blocks, or roughly 28 seconds, faster. Polymarket says trades, positions and balances will update much faster under the new infrastructure. Goldsky will remain as a backup while Polymarket primarily runs its own indexing system. Polymarket Vice President of Engineering Josh Stevens said the prediction market platform built the new system internally using rindexer, an open-source indexing tool written in Rust. The infrastructure can index data within 0 to 10 milliseconds of a block being broadcast, according to Stevens. “We now see onchain data events up to 14 blocks (28 seconds) faster, and we index within 0-10ms of block broadcasting, making it nearly instant,” Stevens said. The change means trades, user positions and balances can update more quickly as blockchain events reach Polymarket’s systems. Stevens said Goldsky, which previously handled impo...
