Polygon fixes RPC node bug, consensus returns to normal

The Polygon Foundation, the enactment that oversees improvement of the layer-2 scaling web successful the Ethereum ecosystem, said connected Wednesday that statement and finality functions person been restored, pursuing a bundle bug that caused immoderate nodes to autumn retired of sync with the blockchain.

Polygon successfully executed a hard fork following the bundle bug that disrupted immoderate distant process telephone (RPC) nodes, which are utilized to relay accusation betwixt applications and the blockchain layer, the Polygon squad said successful Wednesday’s update.

The bug was caused by a “faulty” connection from a validator, which pushed immoderate of the Bor nodes, utilized for transaction ordering and artifact production, onto divergent web forks, according to Polygon co-founder Sandeep Nailwal. Nailwal said:

“We rolled retired fixes connected some Heimdall v0.3.1 — a caller mentation with a hard fork to delete the identified milestone — and Bor 2.2.11 beta2, purging the milestone from the database. With these fixes present live, nodes are not stuck, checkpoints and milestones are finalizing normally.”

Software bugs continue to origin blockchain outages. As cryptographic protocols go much analyzable by hosting astute declaration functionality, record retention and cross-chain interoperability, bugs whitethorn go much frequent, disrupting the onchain idiosyncratic experience.

Polygon experiences 2nd bundle bug since July

Wednesday’s bundle bug did not halt artifact accumulation connected Polygon; instead, the contented impacted node communication, causing a discrepancy betwixt artifact accumulation and what the impacted nodes were relaying.

Polygon faced a akin contented successful July erstwhile the Hemidall mainnet, the statement lawsuit that relays connection betwixt nodes for Polygon’s proof-of-stake (PoS) statement mechanism, was halted for an hour.

Like Wednesday’s incident, artifact accumulation connected the web ne'er ceased, and caller blocks continued to beryllium added to the concatenation via the Bor mainnet.

The statement layer’s partial outage was owed to a validator exiting the network, Polygon spokespeople told Cointelegraph astatine the time.

Following the unnamed validator’s exit, respective RPC nodes had to resynchronize with the blockchain and reestablish connection to resume mean functionality connected the layer-2 network.
