Web3 Crash Course: From Basics to Advanced Concepts

This crash course will introduce you to key concepts and practical knowledge to help you navigate the Web3 Space.

Basic Concepts

1. Blockchain/DLT (Distributed Ledger Technology)
- A decentralized, transparent, and immutable digital ledger
- Records transactions across multiple computers

2. Cryptocurrency
- Digital or virtual currencies built on blockchain technology

3.Web3
- Communities on top of crypto
- Enables user ownership and control of data and digital assets

4. Blockchain Ecosystems
- Various blockchains exist with different properties and purposes
- Each has its own community and use cases (e.g., Ethereum, Solana, Polkadot)

5. Cryptography Basics
- Private keys: Secret codes that prove ownership and allow transactions
- Public keys: Derived from private keys, used to receive funds
- Addresses: Shortened versions of public keys for easier use

6. Wallets
- Software or hardware tools to interact with blockchain e.g. send currencies
- Browser wallets e.g. Metamask

7. Gas Fees
- Transaction costs paid in a blockchain's native token
- Compensates network validators for processing transactions

8. Tokens and Utilities
- Cryptocurrencies built on existing blockchains (e.g., ERC-20 tokens on Ethereum)
- Can represent various assets or utilities like voting rights in DAOs

9. Interaction with wallet:
- Seed phrase
- Connect to website
- sign message
- execute transaction

Advanced Concepts

1. Layer 2 Solutions (L2s)
- Built on top of existing blockchains to improve scalability and reduce fees
- Examples: Optimism, Arbitrum, Polygon

2. Multisignature Wallets (Multisigs)
- Require multiple signatures to authorize transactions
- Enhance security and enable shared control of funds

3. Decentralized Finance (DeFi) Basics
- Decentralized Exchanges (DEXs): Trade cryptocurrencies without intermediaries
- Bridges: Transfer assets between different blockchains
- token allowance/revoking with Revoke.cash

4. Advanced DeFi
- Lending protocols: Borrow or lend cryptocurrencies
- Liquidity pools: Provide assets to DEXs and earn rewards

5. Public Goods
- Platforms for donations and grants in cryptocurrency
- Examples: Gitcoin, Giveth, Octant

6. DAOs and Coordination
- Decentralized Autonomous Organizations
- Community-led entities with shared treasuries and decision-making

7. Quadratic voting/funding, and other voting mechanisms e.g. conviction voting

Practical Tips

1. Fiat-Crypto Conversion (On/Off Ramps)
- How to buy cryptocurrencies with traditional money and vice versa

2. Living on Crypto
- Services accepting crypto payments: hotels, flights, transportation, food
- Crypto debit cards for everyday purchases

3. Safety and Security
- Always double-check addresses before sending funds
- Use hardware wallets for long-term storage of significant amounts
- Be wary of phishing attempts and too-good-to-be-true offers


Remember, the Web3 space is rapidly evolving. Stay curious, keep learning, and always do your own research (DYOR) before making any financial decisions.

Juicebox v4, a web3 crowdfunding platform, will be launched on Mainnet, Optimism, Arbitrum, Base allowing to issue same token across all chains!

It’ll make it much easier to issue token!

DeSpace: Bringing the Web3 to Outer Space

Short for "Decentralized Space," it's a fancy term for projects that mix space exploration with web3 tech.

Possible applications:
1. Space Daos
2. Space-focused DeFi tools
3. Utilizing web3 voting systems like Quadratic Voting, or Conviction Voting for Space Exploration

At it's core it's all about people passionate about Space Exploration and Decentralization

Gitcoin GG22 stars on Oct 23.

No DeSci round this time, but check others, maybe you could get on some rounds with your projects

https://grants.gitcoin.co

Conviction voting

Conviction voting is a form of voting that allows token holders to express their support for multiple proposals over time.

You vote for an option and with time the strength of your vote increases according to predefined formula.

It could be applied to situation, where continues voting makes sense, e.g. in project eligibility for the grants round. Instead of qualifying projects right before the round by a small group of selected stewards why not to rely on community votes?

Often people in the community do not have time to go over tons of applications/proposals over a short period of time, but if it'll be distrubted across a longer period more people would be able to cast their vote.

HyperDeSci is about experimenting with novel mechanisms and Gardens provides us not just with a tool to make it happen, but also to raise some funds on their upcoming round, later to be distributed via Conviction voting on Gardens.

Let's do some fun(draising), so:

1. Create a profile on Gardens on Arbitrum and join HyperDeSci community (you'll have to stake 1 Arb, let me know if you do not have and I'll send):
https://app.gardens.fund/gardens/42161/0x912ce59144191c1204e64559fe8253a0e49e6548/0xc3ba42da1d9f6b09d4d1315ac04f873a5ba64d3c
2. Later the funds from Gardens QF would be distributed via Gardens mechanisms to projects that would apply.
3. If you do not have a project - plz still apply, so later you'll be able to vote for projects, if they are DeSci/should be eligible for grants distribution or not

Please create a profile and join HyperDeSci by 17th of October to make us eligible for the round.

PS I expect that participating project would get a couple of hundred of $, some exp with Conviction voting. It would take a couple of hours on a course of several weeks

A few hours ago this cryptopunk was sold for 24 000 $ETH (~$56mln)

To make it easier to coordinate on irl events in Chiang May Archipelago I e made a group on tg
