Neo X TestNet v0.6.0 adds Ethereum Osaka fork support, Geth v1.16.9 base
Neo X TestNet has been upgraded to v0.6.0 “Rarefaction,” introducing assist for Ethereum’s Osaka fork, a rebased Geth v1.16.9 basis, and the brand new BEACON/2 P2P protocol for improved community synchronization. The discharge is totally suitable with Neo X v0.5.3. The discharge, introduced by Neo World Growth on June 11, continues the chain’s sample of monitoring upstream Ethereum execution layer adjustments.
Neo X is constructed as a fork of Geth, Ethereum’s Go-based shopper implementation, maintained by Bane Labs. As such, it inherits execution layer upgrades from Ethereum’s roadmap. The v0.6.0 replace is the newest in a collection of TestNet releases which have progressively modernized Neo X’s structure, following the post-merge mannequin launched in v0.5.2 earlier this 12 months.
Osaka fork activation
Osaka is the execution layer part of Ethereum’s Fusaka improve, which mixed the Fulu consensus layer with Osaka and went reside on Ethereum MainNet in December 2025. Neo X TestNet will activate Osaka at Unix timestamp 1781500000, roughly June 15 at 5:06 a.m. (UTC).
BEACON/2 protocol and EIP-4844 enhancements
The discharge introduces BEACON/2, an up to date model of the beacon P2P protocol first deployed in v0.5.2. The brand new protocol model improves transaction synchronization via a proposal-aware search cache, block synchronization through handshake-triggered fetcher notifications, and blob synchronization with an improved sidecar fetcher. Older beacon protocol variations shall be eliminated in future releases, making the improve important for continued community participation.
EIP-4844 blob transaction assist, initially launched in v0.5.0 and expanded with devoted storage and question APIs in v0.5.2, has additionally been additional improved. The discharge notes don’t specify the precise adjustments, although associated bug fixes tackle blob synchronization configuration and sidecar fetcher habits.
Geth v1.16.9 safety fixes
The underlying Geth codebase has been up to date to v1.16.9, a safety hotfix that addresses P2P-layer vulnerabilities CVE-2026-26314 and CVE-2026-26315. The Ethereum Basis really helpful that operators recreate P2P node keys following the replace. Node operators working Neo X TestNet infrastructure ought to pay attention to this steerage.
Extra enhancements embrace upgraded execution-layer downloader assist for post-merge backfilling, gentle verification for consensus-layer beacon belief extension, and refactored synchronization standing checks. Bug fixes tackle points with dBFT seal hash computation, transaction alternative habits, and RPC error responses for under-priced transactions.
Improve path
The replace is a suitable rolling improve that requires no chain reset. Operators upgrading from v0.5.3 ought to obtain the brand new binary and genesis file, cease the node, exchange the binary, initialize the database with the brand new genesis file utilizing geth init, and restart. Nonetheless, as with the v0.5.2 launch, the P2P protocol migration means nodes working variations older than v0.5.2 can now not obtain execution-layer block broadcasts. Operators are urged to improve promptly to take care of synchronization.
No MainNet deployment timeline has been introduced for v0.6.0. The complete launch notes might be discovered on the hyperlink under:
