2. The Ethereum Blockchain

  • Ethereum is a public Blockchain. Its main interface is Etherscan.

  • Smart Contracts are self-executed contracts that enables end-to-end transactions, removing the need of many third parties such as brokers, escrow, lawyers or courts. (code is law!)

  • All is needed to interact with Ethereum is a wallet

  • An ICO is a DeFi instrument for CrowdFunding: A certain amount of token is issued and sold in exchange of cryptocurrency

3. Initial Coin Offering (ICOs) : Access Tokens

  • An ICO is a DeFi instrument for CrowdFunding: A certain amount of token is issued and sold in exchange of cryptocurrency

  • Buyers invest in a token often with the expectation of it being a future functional unit of currency (speculative investment)

An ICO removes intermediaries such as venture capitalists, investment firm, banks, and stock exchanges.

4. StableCoins (Asset-Backed Tokens)

  • An Asset-Based Token is a form of Digital Stock
  • Each token represents an ownership right of the underlying asset
  • Minting and Redeeming token done by the issuer (not trustless!)

cache, contract

4. MakerDAO and the Dai token

  • The MakerDAO is a plateform that lets users take out a loan in Dai
  • Dai supply is collaterized by other valuable crypto assets
  • Trustless! Minting and Burning purely based on Smart-Contracts Interactions
  • The Dai token is a StableCoin softly-pegged to USD (1 DAI = 1 USD)

5. Decentralized Exchanges and P2P markets

  • ~2B$ to 3B$ liquidity provided
  • Daily Trading Volume peaked ~ 1B$ (overtaking CoinBase), current
  • Only 10 employees (coinbase 1000 employees)
On 16th of September, Uniswap team announced the UNI governance token.
1 Billion UNI token distributed to over 50 000 addresses.
