 While specific timelines may vary, the development of JAM typically involves ongoing research,
 testing, and iteration. The RFC will be published as a first step, where the community gives

 ## Do parachains need to rewrite their code? How much work is it to build?
 
 Parachains will be one of the “products” that can run on JAM. JAM will only remove the enshrined
-parachain consensus and replace it with a model that supports different services. For the first

 ## Does it even make sense now to build a parachain on Polkadot?
 
 Of course! Parachains will be one of the “products” that can run on JAM, and they will stay
 first-class citizens. There will be different use cases, some suitable for parachains and some
-suitable for services. Also, JAM is a research project in its very early stages (see
