TRON DAO has officially released GreatVoyage v4.8.2 (Pyrrho), a mandatory network upgrade that all node operators must install by August 16, 2026, 23:59 SGT to avoid synchronization issues. The update focuses on fortifying Ethereum compatibility, protocol security, and node performance.
The TRON Virtual Machine (TVM) now aligns more closely with Ethereum’s Pectra and Osaka upgrades, introducing the CLZ (Count Leading Zeros) opcode and a precompiled contract for secp256r1 signature validation. These additions enable compatibility with modern authentication methods such as Apple Secure Enclave, WebAuthn, and Android Keystore. The MODEXP precompile also gains input limits, standardized signature validation, and updated pricing, easing the migration of Ethereum-based dApps to TRON.
Core protocol improvements include TIP-2935, which stores historical block hashes to support stateless clients, Layer-2 solutions, and enhanced interoperability. Other changes involve BigInteger-based resource window calculations, stricter calldata verification, and adjustable time limits for contract calls, all enhancing execution reliability and long-term scalability.
On the infrastructure side, TRON replaced the Fastjson library with Jackson for JSON processing, improved JSON-RPC compatibility, and migrated node monitoring from InfluxDB to Prometheus. The Event Plugin has also been updated to version 3.0.0, and operators using it must upgrade first. These changes collectively strengthen network reliability, developer experience, and monitoring efficiency.
