Ethereum vs Solana Roadmaps: Where Both Networks Are Headed

TL;DR

• Ethereum’s Strawmap treats the L1 as a decentralized settlement and data-availability base coordinating an ecosystem of L2 rollups.
• Solana’s Alpenglow treats the L1 as a single global state machine, replacing TowerBFT and removing Proof of History from core consensus.
• Alpenglow targets 100-150ms finality, down from 12.8 seconds, and passed governance with 98.27% approval under SIMD-0326.
• Strawmap outlines roughly 7 hard forks through 2029, targeting 10,000 TPS on L1 and 10 million TPS across rollups.
• Both roadmaps reshape the validator job. Everstake has operated non-custodial validator infrastructure on both networks and since early days.

What is Solana and Ethereum PMF?

Ethereum and Solana now answer two different design questions, which is why their roadmaps pull apart. 

Network	Core question	End-state vision
Ethereum	How does a decentralized settlement layer support an ecosystem of rollups?	L1 as settlement and data-availability base; L2s handle execution
Solana	How can one blockchain approach internet-tier responsiveness?	L1 as a single global state machine handling execution and settlement

What is Alpenglow

Alpenglow is Solana’s largest consensus change since the network’s 2020 launch, formalized under governance document SIMD-0326. It replaces TowerBFT and removes Proof of History from core consensus. It passed validator governance with 98.27% approval and is in test-cluster phase, with mainnet targeted for late 2026 early 2027.

The upgrade introduces two components in place of the old stack:

• Votor, a direct-vote finality protocol that collapses the prior 32-round confirmation process into 1 or 2 rounds.
• Rotor, a block-propagation system replacing the multi-layer Turbine relay tree.

Alpenglow targets 100-150ms finality, down from roughly 12.8 seconds under TowerBFT. When 80% of validator stake is active, Votor finalizes in a single round near 100ms. At 60% participation, it takes 2 rounds, targeting 150ms.

The upgrade also eliminates on-chain vote transactions. Those votes currently consume roughly 75% of Solana block space, so removing them frees that capacity for user transactions.

Solana’s direction: the L1 as a single global state machine

Solana’s roadmap keeps everything on one base layer, and Alpenglow signals that same direction. The network is optimizing for internet-tier responsiveness rather than offloading execution to a separate scaling layer. Settlement happens on the base layer, not on rollups above it.

Cutting confirmation from 12.8 seconds to 100-150ms is roughly an 80-100x improvement, aimed at high-frequency DeFi and payments.

Faster finality also reshapes MEV economics on Solana. Anatoly Yakovenko has noted that the window for reordering shrinks when blocks finalize in milliseconds.

Ethereum’s direction: a settlement and data-availability layer

Ethereum’s Strawmap treats the L1 as the coordination and settlement base for an ecosystem of L2s. The roadmap, introduced by Ethereum Foundation researcher Justin Drake on February 25, 2026, frames the base layer around security, settlement, and data availability. Execution diversity lives on rollups.

The Strawmap does not remove rollups, but it strengthens the L1 beneath them. Its Teragas L2 north star targets 1 GB/sec of data-availability bandwidth, framed as roughly 10 million TPS across rollups. The Gigagas L1 north star targets roughly 10,000 TPS on the base layer via embedded zkEVMs.

Vitalik Buterin has said that relying heavily on rollups alone for scaling no longer makes full sense. Wider data availability still benefits rollups, while faster finality and zk-L1 execution may move more settlement logic back to the base layer.

Ethereum vs Solana: a roadmap comparison

Ethereum and Solana diverge significantly. Ethereum focuses on a modular, rollup-centric architecture where the L1 acts as a secure settlement and data-availability layer, while Solana maintains a monolithic, integrated design that optimizes for high-performance execution on a single base layer.

Dimension	Ethereum (Strawmap)	Solana (Alpenglow)
Core question	Settlement layer for rollups	One internet-tier state machine
Consensus	PoS with ePBS; Minimmit finality researched	Votor replaces TowerBFT
Finality target	6-16 seconds (from 16 minutes)	100-150ms (from 12.8 seconds)
Scaling model	L1 settlement plus L2 execution	Single global state machine
End-state	10,000 TPS L1 / 10M TPS L2	Unified base-layer execution
Operator profile	CL plus EL clients; zk hardware ahead	Lower entry barrier; off-chain voting

Roadmap milestones for 2026

Both networks have concrete near-term items scheduled for 2026. Ethereum’s Strawmap sketches roughly 7 hard forks through 2029 at a cadence of one every 6 months. Solana’s Alpenglow moves from the test cluster toward mainnet.

The near-term items on each side include:

1. Ethereum Glamsterdam, targeting end of August 2026 or later, with headliners EIP-7732 (ePBS) and EIP-7928 (Block-Level Access Lists).
2. Ethereum Hegotá, targeted for late 2026 or early 2027, carrying FOCIL (EIP-7805) for censorship resistance.
3. Solana Alpenglow, in community test-cluster phase, with mainnet expected late 2026 after the Agave 4.1 release in Q3 2026.

What each path means for operators and stakers

Each roadmap reshapes the operator and staker reality differently. Solana’s Alpenglow lowers the validator entry barrier through off-chain voting plus the Validator Admission Ticket (VAT), proposed at 1.6 SOL per epoch under SIMD-0357. The VAT is charged to validators, not deducted from delegator rewards.

Ethereum’s rollup-centric L1 changes staking economics through upgrades like ePBS. Currently 40 million ETH is staked (about 32.12% of supply), across 1.1 million active validators.

The operator demands differ by network:

• Solana under off-chain voting plus VAT allows HSM-friendly identity keys and a lower hardware barrier.
• Ethereum validators run both consensus-layer and execution-layer clients, with zk-proof hardware requirements ahead.
• Both face shifting MEV capture, via ePBS and FOCIL on Ethereum and faster finality on Solana.

Where validators fit

Everstake provides non-custodial validator infrastructure for institutional stakers on both networks, so both roadmaps directly influence the processes.

The non-custodial role means stakers keep custody while Everstake runs the node infrastructure. Everstake holds SOC 2 Type II, ISO 27001:2022, and maps controls to the NIST CSF.

The two roadmaps change the validator job. On Solana, off-chain voting and VAT lower the barrier and reshape cost accounting. On Ethereum, heavier cryptography and dual-client operation raise the technical bar over time.

Everstake has run validator infrastructure across 130+ networks, tracking each roadmap so stakers do not have to. For prior context, see this breakdown of the Ethereum upgrade roadmap and this analysis of institution-centric vs open architecture. 

FAQ

What is Alpenglow?

Alpenglow is Solana’s largest consensus upgrade since the network launched in 2020, formalized under SIMD-0326. Everstake notes it replaces TowerBFT and removes Proof of History from core consensus, targeting 100-150ms finality.

Does Alpenglow remove Proof of History?

Yes. Alpenglow removes Proof of History from core consensus and replaces it with a fixed 400ms block time using local timeouts. 

What is Solana’s finality target?

Solana’s Alpenglow targets 100-150ms finality, down from roughly 12.8 seconds under TowerBFT. The single-round finality near 100ms requires about 80% of validator stake to be active.

Is Ethereum becoming a settlement layer?

Ethereum’s Strawmap frames the L1 as a settlement and data-availability base for an ecosystem of rollups. The roadmap targets roughly 10,000 TPS on L1 and 10 million TPS across L2s by 2029.

Will Ethereum or Solana win?

Ethereum and Solana are now solving different problems, so a direct winner framing does not fit. Everstake operates validators on both networks and views them as distinct architectural bets rather than competitors on one roadmap.

What does Alpenglow change for validators?

Alpenglow lowers the validator entry barrier through off-chain voting and introduces the Validator Admission Ticket (VAT) at 1.6 SOL per epoch under SIMD-0357. The VAT is charged to validators, not deducted from delegator rewards.

What is TowerBFT?

TowerBFT is Solana’s original voting mechanism, requiring 32 rounds to reach economic finality at roughly 12.8 seconds. Alpenglow replaces it with Votor, which finalizes in 1 or 2 rounds.

When does Glamsterdam activate?

Ethereum’s Glamsterdam targets mainnet activation at the end of August 2026 as the internal working target, but it could arrive later. The headliners are EIP-7732 and EIP-7928.
