The document summarizes a workshop on AltLayer, an application-tailored Layer 2 scaling solution. It describes issues with current general purpose Layer 1 and Layer 2 networks, and introduces AltLayer's approach of launching disposable "flash layers" optimized for specific applications. Examples are provided of AltLayer hosting a successful NFT minting event and an online PvP game without transaction fees spikes. Upcoming events like a hackathon are also advertised.

3. Issues Faced by Popular Applications
on General Purpose L{1,2}s — Ethereum Edition
The Otherdeed Land Sale Gas War
Over 20,000 ETH was burnt as
gas fees in the heavily hyped
Otherdeed land sale.
Each user spent an average of
2-3 ETH in gas fees alone.

4. Issues Faced by Popular Applications
on General Purpose L{1,2}s — Polygon Edition
Sunflower game on Polygon
PoS consumed over 40% of
the blockspace.
Created negative externalities
for users of other dApps.

5. Issues Faced by Popular Applications
on General Purpose L{1,2}s — Arbitrum Edition
Arbitrum’s NFT campaign was
paused due to ensuing congestion
on the network.
Gas fees on Arbitrum was higher
than that on Ethereum L1.

6. Shared blockspace model
offered by general purpose
L{1,2}s is not ideal for most
popular dApps due to poor
UX and lack of flexibility for
devs.
Why AltLayer?

A platform to launch application-tailored L2 execution layers.

Flash Layers Create Resource
Optimisation for dApps
Init Exec Free
Consider an NFT sale happening on an L1. As the developer notices
a surge in demand, he initiates a flash layer.
Once the NFT sale has been completed on the flash layer, the state
is committed to the L1. The flash layer is subsequently freed and
taken down.
Flash layers are disposable
application-tailored rollups with
optional fraud proofs.
Disposability makes them
highly resource optimised.

9. Flash layer offers several
advantages over one-size-fits-all
offerings from other appchains
(e.g., Cosmos SDK).

Verifier
Verifier checks the
correctness of proof of
validity. It updates network
progression on the L1 chain
by creating a fraud proof.
Block
producer
Block producer processes each
transaction in EVM/WASM.
Producer generates and
consolidates blocks and states
into WebAssembly as proof of
validity.
Aggregator
Aggregator receives and
tags transactions with
timestamp and sends them
to the block producer.

At least one light-client/hardware/dApp/user verifies the block.

14. 1. Real-World Validation with AltLayer’s
OG Badge NFT Mint Event
NFTs Minting
Hosted a POAP-style mint event
on a flash layer. Setup was
designed to create a burst in
demand.
•12k whitelisted minters
•No KYC
•Freemint
•No need to acquire gas

400 NFTs settled on

15. - 94K transactions per day; txns equivalent to approx 60% of
txns on all Arbitrum dApps, and over 90% of all txns on
Optimism.
2. Hosting Blockchain PvP Games, with
~190k txs w/o creating fee spike
