Features
Optimistic rollup 
ZK-rollup 
Proof
Uses fraud proofs to prove transaction validity. 
Uses validity (zero-knowledge) proofs to prove transaction validity. 
Capital efficiency
Requires waiting through a 1-week delay (dispute period) before withdrawing funds. 
Users can withdraw funds immediately because validity proofs provide incontrovertible evidence of the authenticity of off-chain transactions. 
Data compression
Publishes full transaction data as calldata to Ethereum Mainnet, which increases rollup costs. 
Doesn't need to publish transaction data on Ethereum because ZK-SNARKs and ZK-STARKs already guarantee the accuracy of the rollup state. 
EVM compatibility
Uses a simulation of the Ethereum Virtual Machine (EVM), which allows it to run arbitrary logic and support smart contracts. 
Doesn't widely support EVM computation, although a few EVM-compatible ZK-rollups have appeared. 
Rollup costs
Reduces costs since it publishes minimal data on Ethereum and doesn't have to post proofs for transactions, except in special circumstances. 
Faces higher overhead from costs involved in generating and verifying proofs for every transaction block. ZK proofs require specialized, expensive hardware to create and have high on-chain verification costs. 
Trust assumptions
Doesn't require a trusted setup. 
Requires a trusted setup to work. 
Liveness requirements
Verifiers are needed to keep tabs on the actual rollup state and the one referenced in the state root to detect fraud. 
Users don't need someone to watch the L2 chain to detect fraud. 
Security properties 
Relies on cryptoeconomic incentives to assure users of rollup security. 
Relies on cryptographic guarantees for security.

WEB3 HACKATHON OVERVIEW

Best Hackathons for Web3 Developers [2022]

Build at the Best Web 3 Hackathons to Improve Skills and Earn Funding
Last Updated:
July 14, 2022

Every year, there are dozens of hackathons hosted by a variety of companies in the Web3 space. For beginners and veterans in Web3, hackathons are a terrific way to learn blockchain development, turn hackathon ideas into a reality, manage blockchain projects in hybrid work environments, use web3 GitHub repositories, and more. 

Here are some reasons why you should consider participating in a Web3 hackathon, and four of the greatest hackathons in the industry from this year.

What is a hackathon?

A web3 hackathon is an event hosted by blockchain protocols, web3 dApps, companies, or web3 hackathon event producers to give web3 developers resources, an environment, incentives, and direction for creating functional minimum viable products (MVPs). 

Hackathon Tracks

Web3 hackathons typically offer incentives for blockchain projects centered on multiple different tracks such as niche (e.g. NFTs, DeFi, Metaverse), region (e.g. US, Africa, Europe), or technology (e.g. a new library, protocol, or dApp).

Project submissions are commonly split up into multiple tracks, each focusing on a different use-case of blockchain. Aside from competing for track-specific rewards, hackathons may also feature bounties–rewards for projects that complete specific challenges designed by sponsors. 

Hackathon Duration

Traditionally, hackathons take place over a week or weekend of hacking with a team of developers and designers. However, hackathons in web3 have also expanded to include month-long schedules to give teams ample time to learn new technologies, test their dApps, and launch functional MVPs.

Hackathon Location

Traditionally, hackathons take place in-person hacking, however, due to restrictions imposed by the COVID-19 pandemic and the rise of remote work, many hackathons also allow devs to participate online while collaborating with teams through Discord, Telegram, and other web3 team communication platforms.

Hackathon Judging

At the end of the hackathon schedule, all the submitted projects will be judged by a panel of judges, typically web3 influencers, blockchain investors, and dApp founders, to award the best hackathon projects with cash prizes, grants, and exposure to big industry names. 

Hackathons often offer plenty of developer support, guiding contestants of all backgrounds to learn new technologies and grow from the hacking experience.

Web3 Hackathon Benefits

Hackathons are an amazing opportunity for new and existing web3 developers to turn ideas into an actual product, and potentially a venture-backed Web3 startup. 

Throughout the process developers get to:

  • Find a community of like-minded individuals, all highly motivated to create in Web3
  • Learn how to build products using innovative technology and primitives
  • Attend educational events and hear talks from industry leaders
  • Find inspiration alongside cutting-edge blockchain project ideas
  • Win financial prizes for your accomplishments
  • Meet web3 investors, analysts, and fund managers
  • Network with builders and investors

Above all, hackathons give developers an opportunity to put into practice the skills they've learned completing online web3 developer courses, scouring countless blockchain newsletters, and learning through web3 tutorials to put their practice into action.

With so many protocols using hackathons as a crypto marketing strategy and new organizations receiving funding to manage hackathon events throughout the entire year, getting started as a web3 developer at hackathons has never been easier.

Best Web3 Hackathons

The best hackathons are determined by the quality of developers that attend, the quality of judges and investors in attendance, the quality of talks and side events, the prize pool, the resources provided to developers, and the technologies that builders are incentivized to use.

Because there are so many hackathons and a limited amount of time to build applications, web3 developers must decide which hackathon is the best event to attend. 

In this article we will explore four hackathons: 

  1. ETHDenver BUIDLathon
  2. Solana Summer Camp
  3. Polygon BUIDLit
  4. ETHOnline

Although one hackathon has finished, and two are currently in progress receiving submissions, these hackathons happen each year, so you can start planning to attend them in the future.

1. ETHDenver BUIDLathon

‍ETHDenver’s BUIDLathon hackathon occurred from February 11th to 20th in 2022 where contestants participated both in-person and virtually, competing for separate rewards pools. Winners took part in over $1 million in bounties and prizes, and $2 million in investments.

Web3 hackathons typically offer incentives for blockchain projects centered on multiple different tracks such as niche (e.g. NFTs, DeFi, Metaverse), region (e.g. US, Africa, Europe), or technology (e.g. a new library, protocol, or dApp).

Project submissions are commonly split up into multiple tracks, each focusing on a different use-case of blockchain. Aside from competing for track-specific rewards, hackathons may also feature bounties–rewards for projects that complete specific challenges designed by sponsors. 

Hackathon Duration

Traditionally, hackathons take place over a week or weekend of hacking with a team of developers and designers. However, hackathons in web3 have also expanded to include month-long schedules to give teams ample time to learn new technologies, test their dApps, and launch functional MVPs.

Hackathon Location

Traditionally, hackathons take place in-person hacking, however, due to restrictions imposed by the COVID-19 pandemic and the rise of remote work, many hackathons also allow devs to participate online while collaborating with teams through Discord, Telegram, and other web3 team communication platforms.

Hackathon Judging

At the end of the hackathon schedule, all the submitted projects will be judged by a panel of judges, typically web3 influencers, blockchain investors, and dApp founders, to award the best hackathon projects with cash prizes, grants, and exposure to big industry names. 

Hackathons often offer plenty of developer support, guiding contestants of all backgrounds to learn new technologies and grow from the hacking experience.

Web3 Hackathon Benefits

Hackathons are an amazing opportunity for new and existing web3 developers to turn ideas into an actual product, and potentially a venture-backed Web3 startup. 

Throughout the process developers get to:

  • Find a community of like-minded individuals, all highly motivated to create in Web3
  • Learn how to build products using innovative technology and primitives
  • Attend educational events and hear talks from industry leaders
  • Find inspiration alongside cutting-edge blockchain project ideas
  • Win financial prizes for your accomplishments
  • Meet web3 investors, analysts, and fund managers
  • Network with builders and investors

Above all, hackathons give developers an opportunity to put into practice the skills they've learned completing online web3 developer courses, scouring countless blockchain newsletters, and learning through web3 tutorials to put their practice into action.

With so many protocols using hackathons as a crypto marketing strategy and new organizations receiving funding to manage hackathon events throughout the entire year, getting started as a web3 developer at hackathons has never been easier.

Best Web3 Hackathons

The best hackathons are determined by the quality of developers that attend, the quality of judges and investors in attendance, the quality of talks and side events, the prize pool, the resources provided to developers, and the technologies that builders are incentivized to use.

Because there are so many hackathons and a limited amount of time to build applications, web3 developers must decide which hackathon is the best event to attend. 

In this article we will explore four hackathons: 

  1. ETHDenver BUIDLathon
  2. Solana Summer Camp
  3. Polygon BUIDLit
  4. ETHOnline

Although one hackathon has finished, and two are currently in progress receiving submissions, these hackathons happen each year, so you can start planning to attend them in the future.
