How Does NEAR Protocol Work?

Threshold Proof of Stake with chunk-based validation across shards

Validators are assigned to validate specific chunks (shard segments) rather than full blocks. With Nightshade 2.0, stateless validation allows validators to verify transactions using cryptographic proofs without storing the entire blockchain state. 100 block producers and up to 10,000 chunk validators.

Fixed annual inflation at 2.5% (halved from 5% in Oct 2025) with 70% to validators and 30% burned

Originally 5% fixed inflation. Governance proposal to halve to 2.5% passed through validator-level vote (68.41% support) despite community vote falling short of 66.67% threshold. Foundation bundled the change into a protocol upgrade regardless.

30% of transaction fees burned, 70% to contract developers (if applicable) or validators

Fee burn mechanism similar to EIP-1559 but with developer reward component. At current usage levels, burn offsets only a fraction of inflation.

NEAR Foundation manages ecosystem treasury with discretionary spending authority

Foundation controls significant treasury for grants, ecosystem development, and strategic initiatives. Centralization concern highlighted by the inflation halving override.

Direct delegation to validators with minimum stake threshold

Token holders delegate NEAR to validators. Minimum validator seat price determined by auction mechanism. ~4.7% staking reward rate.

Algorithmic slashing for double-signing and chunk invalidity

Validators can be slashed for producing invalid chunks or double-signing. Slashing is automatic and enforced at the protocol level.

Rainbow Bridge: trustless lock-and-mint bridge to Ethereum using light client verification

Uses NEAR light client on Ethereum and Ethereum light client on NEAR for trustless verification. Watchdog bots automatically challenge invalid blocks. Successfully repelled two hack attempts in 2022 (May and August), with attackers losing their bonds.

Nightshade dynamic resharding with stateless validation

Nightshade 2.0 (launched 2024-2025) introduces stateless validation where validators no longer need to store the entire blockchain state. Dynamic resharding allows the network to split and merge shards based on demand. Achieved 1M+ TPS in benchmarks across 70 shards. 600ms block time with 1.2s finality.

At current usage levels, the 30% fee burn offsets only ~0.3% of the 2.5% inflation, meaning the system is predominantly dilutive. NEAR needs roughly 8x current transaction volume before burn meaningfully offsets inflation. The inflation halving helps but does not solve the fundamental imbalance.

The Foundation's decision to bundle the inflation halving into a protocol upgrade despite the community vote failing short of quorum demonstrates that validator-level governance can be bypassed when the Foundation controls the release pipeline. This creates a trust dependency on the Foundation for all protocol-level changes.

Bridge security depends on the NEAR light client accurately representing chain state. If a sharding bug causes inconsistent state across shards, the bridge light client could be fed invalid state proofs. The complexity of stateless validation + dynamic resharding increases the surface area for state inconsistency bugs.

When shards split or merge dynamically, validators must be reassigned. During resharding transitions, there is a window where shard security may be temporarily reduced if validator assignment does not keep pace with resharding events. This is largely theoretical but represents a novel attack surface.
