 - The default consensus engine available within the SDK is [Tendermint Core](https://github.com/tendermint/tendermint). Tendermint is the most (and only) mature BFT consensus engine in existence. It is widely used across the industry and is considered the gold standard consensus engine for building Proof-of-Stake systems.
 - The SDK is open source and designed to make it easy to build blockchains out of composable modules. As the ecosystem of open source SDK modules grow, it will become increasingly easier to build complex decentralised platforms with it. 
 - The SDK is inspired by capabilities-based security, and informed by years of wrestling with blockchain state-machines. This makes the Cosmos SDK a very secure environment to build blockchains. 
-- Most importantly, the Cosmos SDK has already been used to build many application-specific blockchains that are already in production. Among others, we can cite [Cosmos Hub](https://hub.cosmos.network), [Iris](https://irisnet.org), [Binance Chain](https://docs.binance.org/), [Terra](https://terra.money/) or [Lino](https://lino.network/). Many more are building on the Cosmos SDK. You can get a view of the ecosystem [here](https://cosmos.network/ecosystem).
