The blog post: https://blog.cosmos.network/sifchain-announces-peggy-cosmos-ethereum-cross-chain-bridge-eeb46a8f91db contains several factual inaccuracies that we would like to see corrected.

Inaccuracies

1. Incorrect use of "Proof of Authority"

The post incorrectly claims that Althea's Peggy uses "Proof of Authority" and that a "select set of pre-ordained validators" control the bridge. This is simply wrong. Peggy processes transactions signed by the current validator set on the Cosmos chain. The only entities that a user of Peggy must trust are the Cosmos validators. Using the terms "select set of pre-ordained validators" and "proof of authority" gives readers of this blog post a false impression of how Peggy works. If Peggy is "Proof of Authority", then the Cosmos Hub is also "Proof of Authority".

2. Misquoting our documentation about the inherent tradeoffs of Proof of Stake
