This document discusses rollup-as-a-service and its benefits for building application-specific blockchains. It notes that building custom blockchains is challenging due to high upfront costs, long development times, and lack of ecosystem. Rollup-as-a-service aims to address this by offering customizable rollups that can be used to host applications with options like native tokens, customized parameters, and add-ons. Examples provided show it can scale to thousands of transactions per second without congesting base layers. A hackathon is announced seeking projects to build on their rollup development platform.

3. dApps Requirements Spectrum

4. Appchain as solution?

5. Fast blocktime
dApps Wishlist for Appchain
Full control over
native token Dedicated blockspace
Custom limits for EVMs Seamless bridging capability

6. Current cookbook for building appchain for dApps
Figure out
requirements
Decide where to build eg. Cosmos, Substrate, Avax subnet, Starknet, Fork Ethereum Client, DIY
Hire and train up a protocol development team
Buidl, Buidl, Buidl
Engage partners to run
validators
1 year later or more -> launch
network
Maintain it 24/7/365

7. Immediate problems
Huge upfront costs -
Compute and manpower
Lose focus on build
core product
Building appchain take
a long time
Appchain lacks of a
vibrant dApp
ecosystem
Lack of the technical
expertise

10. Two Product Offerings
With the Same Underlying Tech
Short-lived
Application-Dedicated
Rollups
aka Flash Layers
Persistent
Application-Dedicated
Rollups
These are optimistic rollups.

11. Customization
Native token
customization
Limit adjustment - Gas limit, contract size

Block time

Gas mechanism adjustment eg. Disable gas price auction
Node hardware specifications

12. Add-ons
Each layer is ship with optional useful pre-installed add-ons that will be
beneficial to the application specific / thematic rollup
Current addons
1RPC private RPC
relayer
NFT minting suite
In
development
NFT marketplace FE and
contracts
VRF for
games

13. At least one honest producer generates the correct block.
At least one light-client/hardware/dApp/user verifies the block.
L1 verifies the fraud proof to ensure the same level of L1 security.
