What is Scroll crypto?

Scroll crypto usually means Scroll, a layer 2 network that runs on top of Ethereum, or SCR, the token tied to it. Scroll is a zk-rollup, so it processes transactions off Ethereum and then posts a mathematical proof that they were handled correctly. It launched its main network in 2023.

What is the Scroll blockchain?

Scroll is not a standalone blockchain. It is a rollup, which means Ethereum is its settlement layer. According to Scroll's documentation, Ethereum stores the data and ordering for the Scroll chain, checks its proofs and hosts its bridge contracts.

The network has three parts:

• Sequencing. An execution node runs transactions and produces Scroll blocks, while a rollup node groups them into batches and posts the data to Ethereum.
• Proving. A pool of provers creates zero-knowledge proofs that the batches are correct. As of October 2026, these run on OpenVM, a proving system Scroll built with Axiom.
• Bridging. A bridge contract on Ethereum moves assets and messages between the two networks.

Scroll is designed to work with Ethereum's tools, so developers can deploy most Ethereum smart contracts with few changes. In that sense it sits in the same group as ZKsync, Starknet and Linea, though each handles proofs and compatibility in its own way.

What is the Scroll token?

SCR launched in October 2024, according to The Block. Its total supply is 1 billion tokens. The planned split was:

• 15 percent for community airdrops
• 25 percent to fund projects building on Scroll
• 20 percent shared between the Scroll DAO treasury and the Scroll Foundation
• 17 percent for investors and 23 percent for contributors

Scroll describes SCR as a governance token, used to vote on how the network and its treasury are run. For the general idea, see what a governance token is.

How decentralized is the Scroll network?

L2BEAT, an independent site that rates rollups, uses stages from 0 to 2 to show how much control a team keeps. In April 2025 Scroll activated an upgrade called Euclid. Decrypt reported that it let users get transactions included without the main operator and added a delay before upgrades took effect. Scroll said this made it the first zk-rollup at Stage 1, with a 12-member Security Council where most members were outside Scroll.

That position did not last. Scroll's DAO was reorganized in September 2025 so that it reports to the Scroll Foundation, which kept a veto. In April 2026 Scroll proposed dissolving the Security Council, saying its cost was not justified by its use. L2BEAT records that the council was replaced on June 1, 2026 by a 3-of-4 admin multisig that can upgrade core contracts with no delay, and it now rates Scroll Stage 0.

In practice, this means users rely more on the Scroll team not to make harmful changes. Users can still force transactions through Ethereum if the operator stalls for more than seven days, according to L2BEAT. These settings can change, so check L2BEAT for Scroll's current rating.
