Move in instructions from inherent transactions to unsigned transactions
The original intent was to use inherent transactions to prevent needing to vote on-chain, which would spam the chain with worthless votes. Inherent transactions, and our Tendermint library, would use the BFT's processs voting to also vote on all included transactions. This perfectly collapses integrity voting creating *no additional on-chain costs*. Unfortunately, this led to issues such as #6, along with questions of validator scalability when all validators are expencted to participate in consensus (in order to vote on if the included instructions are valid). This has been summarized in #241. With this change, we can remove Tendermint from Substrate. This greatly decreases our complexity. While I'm unhappy with the amount of time spent on it, just to reach this conclusion, thankfully tendermint-machine itself is still usable for #163. This also has reached a tipping point recently as the polkadot-v0.9.40 branch of substrate changed how syncing works, requiring further changes to sc-tendermint. These have no value if we're just going to get rid of it later, due to fundamental design issues, yet I would like to keep Substrate updated. This should be followed by moving back to GRANDPA, enabling closing most open Tendermint issues. Please note the current in-instructions-pallet does not actually verify the included signature yet. It's marked TODO, despite this bing critical.

# Consensus
|
||||
|
||||
### Inherent Transactions
|
||||
|
||||
Inherent transactions are a feature of Substrate enabling block producers to
|
||||
include transactions without overhead. This enables forming a leader protocol
|
||||
for including various forms of information on chain, such as In Instruction. By
|
||||
having a single node include the data, we prevent having pointless replicas on
|
||||
chain.
|
||||
|
||||
In order to ensure the validity of the inherent transactions, the consensus
|
||||
process validates them. Under Substrate, a block with inherents is checked by
|
||||
all nodes, and independently accepted or rejected. Under Serai, a block with
|
||||
inherents is checked by the validators, and if a BFT majority of validators
|
||||
agree it's legitimate, it is, regardless of the node's perception.
|
||||
|
||||
### Consensus
|
||||
|
||||
Serai uses Tendermint to obtain consensus on its blockchain. Tendermint details
|
||||
both block production and finalization, finalizing each block as it's produced.
|
||||
|
||||
Validators operate contextually. They are expected to know how to create
|
||||
inherent transactions and actually do so, additionally verifying inherent
|
||||
transactions proposed by other nodes. Verification comes from ensuring perfect
|
||||
consistency with what the validator would've proposed themselves.
|
||||
|
||||
While Substrate prefers block production and finalization to be distinct, such
|
||||
a model would allow unchecked inherent transactions to proliferate on Serai.
|
||||
Since inherent transactions detail the flow of external funds in relation to
|
||||
Serai, any operations on such blocks would be unsafe to a potentially fatal
|
||||
degree. Accordingly, re-bundling the two to ensure the only data in the system
|
||||
is that which has been fully checked was decided as the best move forward.

# In Instructions
|
||||
|
||||
In Instructions are included onto the Serai blockchain via unsigned
|
||||
transactions. In order to ensure the integrity of the included instructions, the
|
||||
validator set responsible for the network in question produces a threshold
|
||||
signature of their authenticity.
|
||||
|
||||
This lets all other validators verify the instructions with an O(1) operation.
