IoTeX Zanzibar Hard fork goes live on mainnet; staking rewards will now be distributed directly on-chain by the protocol
PANews October 19 According to IoTeX official announcement,Zanzibar hard fork has been activated on the IoTeX mainnet (at block height 53,533,081). According to IIP-59, voter rewards will be calculated and distributed on-chain in each reward era, eliminating off-chain services and intermediary steps. Anyone can verify every payment directly on-chain, with the first on-chain distribution to take place the following day. The upgrade also strengthens consensus through proof-of-possession checks for delegate keys, preparing for subsequent BLS signature aggregation. Node operators must upgrade to iotex-core v2.5.1, with no configuration changes or resynchronization required.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
A hard fork is an upgrade to a blockchain protocol's rules. This upgrade moves the calculation and distribution of voter rewards on-chain, allowing users to verify payment records directly; node operators need to update their software version.
Why it matters to readers
Reward distribution no longer relies on off-chain services or intermediary steps, and payments can be verified directly on-chain; delegate key checks also strengthen consensus-related verification.
If you participate in IoTeX voting or staking, you can monitor whether rewards are received under the new mechanism; if you operate a node, you need to upgrade to the specified version.
Risks and unknowns
The report relays IoTeX official statement through PANews; no on-chain transactions or independent verification results were provided as evidence.
The first on-chain reward distribution remains planned for the following day, and whether it will be completed on schedule is unknown.
The progress and compatibility of node upgrades, as well as mainnet operations after the upgrade, have not been specified.
Subsequent BLS signature aggregation is only in the preparation stage, and the specific launch schedule is unknown.
