Blockchain ​

Blockchain is an immutable linked list of hashes that uses some consensus system like proof of stake (or other methods) to decide which blocks (transactions or runnable code) are added next.

Solana, Tezos, Monero, Mimblewimble & Avalanche are interesting blockchains. In future they can let you run web apps that run like protocols -- no company in the middle, just peer to peer networks. In practice now, they are mostly empty promises and lots of fraud.

You should not use a blockchain unless you critically need finality in a shared context with a lot of other financial applications like exchanges, stable coin providers. If you don't need that, don't use a blockchain.

Dark Forest is a unique game built on top of blockchain.

Thirdweb seems like a nice dev framework.

Want to study Dexterity code for how to build a decentralized exchange.

Consensus algorithms ​

  • PoW: The more hashing power the more trust worthy.
  • PoS: The more coins the more trust worthy.
  • PBFT: Hand selected trusted nodes.
  • Randomized asynchronous algorithm: You trust nobody! Every single node is constantly re-evaluated. (Skycoin)
