The Polygon Basis, the group that oversees growth of the layer-2 scaling community within the Ethereum ecosystem, stated on Wednesday that consensus and finality features have been restored, following a software program bug that precipitated some nodes to fall out of sync with the blockchain.
Polygon efficiently executed a tough fork following the software program bug that disrupted some distant process name (RPC) nodes, that are used to relay info between functions and the blockchain layer, the Polygon workforce stated in Wednesday’s replace.
The bug was brought on by a “defective” proposal from a validator, which pushed a few of the Bor nodes, used for transaction ordering and block manufacturing, onto divergent community forks, in accordance with Polygon co-founder Sandeep Nailwal. Nailwal stated:
“We rolled out fixes on each Heimdall v0.3.1 — a brand new model with a tough fork to delete the recognized milestone — and Bor 2.2.11 beta2, purging the milestone from the database. With these fixes now dwell, nodes aren’t caught, checkpoints and milestones are finalizing usually.”
Software program bugs proceed to trigger blockchain outages. As cryptographic protocols turn into extra advanced by internet hosting sensible contract performance, file storage and cross-chain interoperability, bugs might turn into extra frequent, disrupting the onchain person expertise.

Polygon experiences second software program bug since July
Wednesday’s software program bug didn’t halt block manufacturing on Polygon; as a substitute, the difficulty impacted node communication, inflicting a discrepancy between block manufacturing and what the impacted nodes had been relaying.
Polygon confronted an identical subject in July when the Hemidall mainnet, the consensus consumer that relays communication between nodes for Polygon’s proof-of-stake (PoS) consensus mechanism, was halted for an hour.
Like Wednesday’s incident, block manufacturing on the community by no means ceased, and new blocks continued to be added to the chain through the Bor mainnet.
The consensus layer’s partial outage was resulting from a validator exiting the community, Polygon spokespeople advised Cointelegraph on the time.
Following the unnamed validator’s exit, a number of RPC nodes needed to resynchronize with the blockchain and reestablish communication to renew regular performance on the layer-2 community.
