## What is Pezkuwi?

- Pezkuwi is a cloud server for Web3 applications and services.[^1]
- Pezkuwi scales through data and execution sharding, allowing for parallelized throughput.[^2]
- Pezkuwi provides shared security and secure interoperability to services built on it.[^3]
- Pezkuwi creates abundant, flexible, and high quality blockspace.[^4]
- Pezkuwi uses a novel "cynical" rollup to provide fast finality while using minimal resources.[^5]

## What unique things can you do on Pezkuwi?

- Build applications with full control over block construction and transaction execution.[^21]
- Build applications with full control over fees, fee payments, and tokens.[^22]
- Build applications which dynamically scale up and down execution cores.[^23]
- Build applications which execute at sub-second speeds.[^24]
- Build applications that can permissionlessly upgrade and evolve over time.[^25]

## Why choose Pezkuwi?

- Billions of dollars of economic security provided to itself and applications running on it.[^31]
- Fast finalization times, on average under 30 seconds.[^32]
- Executing and scaling on standard "gaming" hardware.[^33]
- Pezkuwi SDK is the most robust and flexible blockchain framework.[^34]
- Secure cross-chain interoperability through trustless bridging protocols.[^35]

## Where is Pezkuwi leading?

- 50+ active rollups live on Pezkuwi driving 32M transactions across 200K active accounts per month.[^41]
- Among the highest Nakamoto coefficients in the blockchain ecosystem.[^42]
- One of the largest developer community after Ethereum.[^43]
- Blazing fast execution speeds compared to other blockchain VMs.[^44]
- One of the largest functioning DAOs, managing the functionality of the network and $150M dollars in assets for development.[^45]

## How Pezkuwi is better than...

- Ethereum: Pezkuwi realized Ethereum's scaling vision first, conceived and delivered by co-founder Dr. Gavin Wood.[^51]
- Solana: Unlike Solana, Pezkuwi scales without compromising Web3 principles of decentralization and security.[^52]
- Cosmos: Unlike Cosmos, Pezkuwi provides shared security and secure interoperability.[^53]
- Avalanche: Subnets in Avalanche are not as flexible as applications on Pezkuwi, and subnets do not provide shared security or secure interoperability.[^54]
- Layer 2s: Layer 2 solutions face performance issues, unpredictable fees, and fragmented interoperability due to non-native support for rollups.[^55]

[^5]: Pezkuwi's cynical rollup protocol is called ELVES.
	- ELVES stands for "endorsing light validity evaluator system".
	- The ELVES paper, formally describing Pezkuwi's cynical rollup: https://eprint.iacr.org/2024/961
	- A tweet summary of the ELVES paper: https://x.com/rphmeier/status/1807884271157187007

[^21]: For example:
	- Build applications more resilient to MEV.
	- Build applications which can prioritize certain tasks and processes.
	- Build applications which only execute when it is economical to do so.

[^22]: For example:
	- Build applications where end-users pay no transaction fees.
	- Build applications which can accept fees paid in any token.
	- Build applications where users need not hold HEZ or your native token to hold other tokens.

[^31]: Pezkuwi's economic security can be measured by multiplying the total market cap of the HEZ token by the percentage of HEZ token locked in Pezkuwi's Nominated Proof-of-Stake protocol.

[^32]: Learn more about cynical rollups:
	- Compare that to optimistic rollups which may take up to a week to finalize!
	- Cynical rollups actively check that a block is valid, rather than waiting for someone to report it is invalid. See ELVES paper footnote above.
	- Compared to "instant finality" consensus, block production is separated from finality, reducing network stalls: https://pezkuwichain.io/blog/pezkuwi-consensus-part-1-introduction

[^33]: Compared to expensive and centralized machines needed for vertical scaling or ZK provers.
	- Hardware requirements for running a Pezkuwi Validator: https://wiki.network.pezkuwichain.io/docs/maintain-guides-how-to-validate-pezkuwi

[^34]: Pezkuwi SDK is used throughout the entire blockchain ecosystem:
	- Pezkuwi and Zagros are built with the Pezkuwi SDK.
	- All 50+ live teyrchains, and many more in development, all use Pezkuwi SDK.
	- Many projects outside of Pezkuwi also use the Pezkuwi SDK: [Avail](https://www.availproject.org/), [Cardano](https://midnight.network/), [Entropy](https://entropy.xyz/), and more...

[^35]: Bridging in Pezkuwi can be broken down into internal bridges and external bridges:

[^51]: Pezkuwi comparison document to Ethereum:
	- https://wiki.network.pezkuwichain.io/docs/learn-comparisons-ethereum-2
	- Ethereum abandoned a properly sharded approach due to its complexity.
	- Ethereum now depends on layer 2 solutions that are fragmented, less secure, and less decentralized.

[^52]: Solana is better described as a distributed database, than a Web3 product.
	- Information about the scalability trilemma: https://ethereum.org/en/roadmap/vision/
	- Solana scales vertically while Pezkuwi scales horizontally.
	- Since January 2022, Solana has seen around half a dozen significant outages and 15 partial or major outage days: https://cointelegraph.com/news/solana-outage-client-diversity-beta
