MagicBlock Ephemeral Validator 1.0.0

MagicBlock Ephemeral Validator 1.0.0 is here!

This release marks a major milestone for Ephemeral Rollups, bringing richer application workflows, broader Solana compatibility, and extensive improvements to performance, reliability, and recovery. It also introduces a new replication service and expands the tools available to validator operators.

Added

• Application workflows: Ephemeral accounts, intent bundles, post-delegation actions, and callbacks. These capabilities enable richer workflows within an Ephemeral Rollup while maintaining a controlled path for settling delegated state back to Solana.
• Settlement capabilities: Commit-finalize flows, automated undelegation, and commit-based fee handling.
• Runtime support: sBPF v3, Token-2022 compatibility, cryptographic precompiles, and syscalls.
• Replication: A new service with primary/replica coordination, AccountsDb snapshots for replicas, and deterministic blockhash checks.
• Settlement recovery: Recovery and retry of pending settlement intents across restarts.
• AccountsDb maintenance: Defragmentation and shrinking support.
• Operator tooling: A validator TUI, account-fetch diagnostics, and Geyser integration and output.

Improved

• Solana compatibility: Updated runtime dependencies to Solana 4.x, aligned rent parameters with the base chain, and improved transaction simulation.
• Account synchronization: More parallel, demand-driven synchronization, with lock-free paths, batched subscriptions and account fetches, and tiered gRPC/WebSocket coverage.
• Resource efficiency: Connection pooling, empty-account caching, reduced RPC traffic, and lower instrumentation overhead in critical paths.
• Transaction processing: Tuned ledger compaction and replication scheduling to reduce contention with transaction execution.
• Persistence and recovery: Improved ledger replay, cache behavior, compaction limits, and shutdown flushing.
• Observability: Structured tracing and expanded lifecycle and latency metrics.
• Release validation: Benchmark regression thresholds, expanded RedSuite coverage, and improved release automation.

Fixed

• Hardened handling of stale and out-of-order account updates.
• Addressed races during account cloning and subscription setup.
• Addressed silently stalled streams and reconnection failures.
• Hardened commit ordering and blockhash consistency.
• Addressed issues in ledger replay and startup/shutdown sequencing.

Experimental

• Replica mode and the challenge protocol remains experimental in 1.0.0.
