Polygon hard fork 'Delhi' successfully completed
The team behind the Ethereum Layer-2 scaling protocol confirmed on Tuesday, January 17, that the planned 'Delhi' upgrade has been successfully completed.

The team behind the Ethereum Layer-2 scaling protocol confirmed on Tuesday, January 17, that the planned "Delhi" upgrade has been successfully executed.
The hard fork is intended to optimize fluctuations in transaction costs and adjust block creation to limit "reorgs". A "reorg" is the temporary split of the blockchain before a consensus is reached on the network. To prevent this, the update provides that validators produce blocks in shorter windows than before.
The second improvement concerns the structure of transaction costs. While the fees generally work well, there can be exponential spikes in transaction costs when the network is busy.
"The goal is to gradually reduce the peaks and ensure a smoother experience when interacting with the blockchain," says the Polygon development team. The "degree of change for base gas costs is expected to fall from the current 12.5 percent to 6.25 percent to reduce sharp swings in gas prices." Matic holders and node operators do not need to take action, as the upgrade was automatically executed.
