Validating a block no longer has to consume energy. It can simply require putting something at stake.

Imagine a validator who sets aside 100 coins as collateral before they can confirm transactions. If they approve a valid block, they receive a small reward, say 2 coins. But if they try to slip in a fraudulent transaction and the network detects it, they lose some or all of that collateral. There’s no need to solve a mathematical puzzle that consumes electricity on a massive scale. You just need to have something to lose.

This mechanism is called proof of stake. Ethereum, for example, switched to this model so validators can $ETH back the network with locked-up capital instead of computation.

KEY CONCEPTS
- The collateral isn’t just for show: if the validator misbehaves, they lose it. There’s still a cost; it’s just taken a different form.
- Depositing collateral doesn’t automatically make anyone honest. Without a clear penalty for backing an invalid chain, some validators might try to support several versions at once.
- Not every part of the industry uses this model, or adopted it at the same time. Other networks still use the previous method, spending electricity to validate.
- Agreement on which block is valid is a technical process among validators, not a popular vote among everyday users.

And that’s the real difference from the energy use of the past: electricity is no longer burned to prove commitment; instead, validators put their own capital at risk. Same problem, different collateral.

Solana prepares Alpenglow for October 21: what’s changing and what’s still pending

On October 13, 2026, Anza announced the planned migration to Alpenglow on the Solana mainnet for October 21. The Solana Foundation guide places activation in epoch 1064; when the sources were checked, it was still listed as not activated.

The goal is to achieve finality in about 150 milliseconds under normal conditions. This is a design target, not a result already measured on the mainnet or a guarantee that every user will experience that wait. It is also not the time between blocks.

The first phase introduces Votor: validators exchange votes directly and bundle them into certificates, instead of sending them as transactions. Program execution does not change. Rotor, another phase focused on distributing block data, is planned for later, with no date set.

One detail to keep in mind when reading the metrics: when votes are removed from blocks, transaction-per-second counts that previously included them may fall. A drop caused by this change in accounting would not demonstrate lower user activity; equivalent metrics will need to be compared.

The migration requires software updates and changes to services that read data from the network. Readiness and operational stability are aspects to monitor; the planned schedule does not replace verifying that activation has actually occurred.

Market perspective: faster finality could benefit payments and applications, but it does not guarantee demand for SOL or a higher price. On Binance, at 05:27 UTC on October 14, SOL was trading at 107.58 USDT (−0.775% in 24 hours) and BTC at 83,606.06 USDT (−0.204%). These are contextual figures, not a reaction attributed to the announcement.
