How Reya Is Different

Based-rollups are novel mechanisms through which developers can create isolated and performant application specific environments that still leverage the security and consensus of Ethereum L1 validators. These types of rollups haven’t been possible until now; for example some of the key technological unlocks, like the introduction of a Deterministic Proposer Lookahead, have only just got the required R&D momentum.

Previously, the main successful attempts at creating a performant onchain DEXs have been via

1. An alt-L1

2. A single-Sequencer Zk Rollup

A based zk rollup is superior to these choices in every way:

	Single-Sequencer Zk Rollup	Alt-L1	Based Zk Rollup
Speed	Very fast	Fast	Very Fast
Economic Security	None	Medium - dependant on L1 assets staked	Excellent - Ethereum L1 Proposers and Execution Nodes
Liveness / Reliability	Low - Single point of failure	Medium - dependant on number of L1 nodes and operators	Excellent - Ethereum L1 Proposers and Execution Nodes
Censorship Resistance / Neutrality	Low - Single point of failure	Medium - dependant on number of L1 nodes and operators	Excellent - Ethereum L1 Proposers and Execution Nodes
Composability	Low - not possible with Ethereum L1 in sychronous manner	Medium - dependant on size of L1 ecosystem	Excellent - synchronous with Ethereum L1

Reya is the first ever trading-specific based zk rollup and a transformational moment for DEX design.
