cosmos and tendermint

you can’t have blockchains that are decentralized, scalable, and secure.

2 schools of though with scalability

• vitalik: rollups

• interoperability between blockchains

  • have blockchains communicate with each other

cosmos is scalable and secure

• network of independent blockchains named ‘zones’

• interoperability b/t blockchains while still allowing blockchains to run in parallel

• each zone contains a chain

  • zones can communicate to each other through cosmos hub

  • cosmos hub records total number of tokens in each zone

  • each zone uses tendermint BFT as its consensus machine and can send and receive tokens

  • zones can transfer tokens/info to each other, but this must go through the hub

  • the hub keeps track of each zone’s state through recent block commits, and zones keep track of hub’s state (much better for scaling)

  • th

• what is tendermint:

  • tendermint is also referred to as the “Tendermint Core,” a protocol that can communicate with blockchains within a network and with external blockchains. With Tendermint, you can create any blockchain system seamlessly. It helps to overcome the time-consuming technical setup phase so you can focus on the application itself.

tendermint consensus engine:

• transactions are recorded on every machine in the same order.
