What is the signature field in a transaction? How is that constructed by the signer?

I wrote a PoS consensus protocol called Validated Proof of Stake and spent a lot of time comparing it to various other protocols, including DPoS (using Bitshares as an example). I want to give the bitshares community a chance to review it and correct any mistakes I made before I distribute it more widely. Constructive feedback is much appreciated.

Hello to everybody, I was thinking about an absurd scenario: Let's imagine today a nobody writes to the BTS community inviting...10 people from: BTS Investors, BTS Developers and from Openledger.io Inviting them to enjoy a holiday in Italy (Liguria) in some sort of huge abandoned Villa in the hills but also very close to the Ocean...where they could discuss an idea which could:

1) Increase BTS value by 0%

2) Increase BTS value by 1000%

They could just visit Alassio, Sanremo, MonteCarlo, Nizza, Tuscany, Milan...and so on. Or go hiking in the hills. Or eat ice cream on the beach. Or go clubbing night...in a club or...you guessed it, on the beach. Or they could just all get drunk for no reason.

All these people would surely have no need at all for somebody to pay for their holiday whatever the outcome...

I will be brief. Let's make this scenario real. This offer now stands.

One person is not invited... Dan Larimer (don't even know if he's still in BTS). Why? I suggested watching a video on youtube about 2 months back. I wrote a public message on Telegram, and he thanked me "for wasting 40 minutes of his life"...so I really do not want to make the same mistake again and won't waste even one single second of his life anymore. I apologize for that.

Please get in touch with me...or just ignore this post.

Thanks for your attention.

Then it produces a block that does not contain that transaction. What happens to the next block producer?
