We've considered implementing this validation pool + forum structure as smart contracts.
However, we expect that such contracts would be expensive to run, because the recursive algorithm for distributing reputation via the forum will incur a lot of computation, consuming a lot of gas.
Can we bake this reputation algorithm into the core protocol of our blockchain?
The structure seems to be similar to proof-of-stake. A big difference is that what is staked and awarded is reputation rather than currency.
The idea with reputation is that it entitles you to a proportional share of revenue earned by the network.
So what does that look like in this context?
Let's say we are extending Ethereum. ETH would continue to be the currency that users must spend in order to execute transactions.
So when a user wants to execute a transaction, they must pay a fee.
A portion of this fee could then be distributed to reputation holders.

# Protocol brainstorming
Each node must build/maintain a view of the history and/or state of the "smart contract" operations.
Nodes must sign messages to each other with asymmetric keys.
This is intended to be an open network that anyone can join.
Each node must verify the results reported by other nodes, and themselves report results to other nodes.
In order to receive payments, the network must solve the same problems that (other) block chains have solved, i.e. must prevent double-spend; must prevent tampering with the ledger.
Storage may be ranked into tiers, where there is core data essential to the integrity of the ledger; ancillary data that is important or desirable for review of the ledger; and supplementary data that is of variable importants for particular use cases, but does not compose the core fabric of the system.

## Client
Clients play a key role in an MVPR DAO.
Clients must be operated by reputation holders.
Clients are the agents that submit posts to the forum, initiate validation pools, and vote in validation pools.
We sometimes refer to the client as "the UI".
It will need to be a network-connected application. It will need a certain minimum of RAM,
and for some features disk storage,
and for some features uptime .
The behavior of the client constitutes what we refer to as the DAO's "soft protocols".
Malicious actors may freely modify their own client's behavior.
Therefore honest clients must engage in policing to preserve the integrity of the network.

A DAO is a group of cooperating entities.
If we're running our own network, it probably makes sense to consider nodes as the participants.
If we're running as smart contracts, it probably makes sense to consider individual addresses as the participants.
These schemes overlap, since both involve asymmetric keys.
Each node must validate the work of the other nodes
Our protocol will be a peer protocol, and will rely on signatures.
Therefore we arrive at a requirement for nodes: they must be physically secured so that private keys are protected.
We also arrive at a requirement for our network protocol: It must be possible to sign messages and verify message signatures against known public keys.
The network protocol MAY support asking peers about other peers / telling other peers about peers.
IF we support this IT SHALL BE linked with each node's reputation.
CAN WE SAY that each node MUST maintain A VIEW of THE ENTIRE / (THE CURRENT) / (ALL / CURRENT) HASHES / MERKLE TREE / -- World state, History
CAN WE GET AWAY WITH ONLY SAYING that each node maintains its own view.
WHAT is our protocol for evaluating the perspectives offered by peers?
- If one node perceives consensus among many others, that may sway their opinion.
- There may be opportunity during "informal voting" / non-binding validation pools (low tokenLossRatio) to gather this sort of information.
- If there is exact agreement, we have a very efficient case.
- If there is the HOPE of exact agreement, mistakes and attacks can be costly
- If there is an EXPECTATION of exact agreement, there must be externalities supporting that agreement, i.e. a common protocol and governance of that protocol.

## Expert submits governance post
A governance post can be considered one that is respected in some way by the operations of the [Client/UI](./client-or-ui.md).
This is a broad class of posts.
Each type of governance post can be individually (or by category?) handled by the business contract for a given DAO.

business -- 2. Post --> forum
business -- 2. Fee $ from<br />internal fund? --> pool
peers -- 3. Stake ℝ<br />to approve --> pool
pool -- 4. Validate --> forum
```
Forum usage is open-ended.
DAO protocol consists of core contracts + client behaviors.
Core contracts provide resilience to attacks, since reputation minting is financially backed by future income
Question: What does the DAO do with funds it receives?
Awswer: Distributes the funds to members immediately upon resolution of the reputation effects of a funded validation pool.
---
Before we delve into example use cases, we need to talk about the [Client/UI](./client-or-ui.md), and make sure we have
a sound understanding of how client/ui behaviors interact with the core of the system.
---
The forum, pool, business, and availability contracts all work together to express a single DAO.
Each post in the forum can be its own new DAO
What it would take for that to happen:
The seed of the new DAO becomes the tokens minted by that post DAO when it receives fees.
When will it receive fees? When submitted to its business contract interface.
What happens then? Work is assigned via availability stakes.
Meaning that someone has staked reputation.
Meaning that they had previously been awarded reputation.
The business contract, or the DAO, or the seed post, must be able to accept an initial fee
to mint the reputation of the first expert.
Then, that expert can stake their reputation on availability to perform the work expressed by the post and its associated business contract.
These operations can be consolidated.
When submitting a post to the forum, you may include an optional fee

In physics, Energy per unit of time is Power.
Energy is in the same units as Work, Potential, Heat, Free Energy,
We've talked about the "power" of a post regarding the effects it has on other posts.
The mechanism of a post exerting its effect also includes the validation pool, which has a duration.
Effective power can be considered as a flow rate of posts; (value per post) / (duration of each post)
Internal energy is similar to Forum total value / DAO total reputation
Total available reputation is similar to thermodynamic free energy

Each DAO needs to allocate some of its incoming fees to incentivize development.
---
Well, the above is not exactly correct. The incentive for development is to earn reputation.
However what is true is that a DAO may need to leverage some reputation toward governance-related actions.
For example gradually changing the weight of some posts bit by bit.
This can be accomplished by a work smart contract that allocates a fixed percentage of minted reputation in the desired way.
If no reputation is needed for such initiatives at a given time, it can be burned instead, to preserve fairness.

At the base layer, we need a peer to peer protocol that allows new nodes to join the network and send and receive messages. It must protect against denial of service attacks. It must support the establishment of consensus, to varying strengths.
We need a lightweight messaging solution to facilitate gathering information from the edges of the network, but we also need to protect against denial of service by malicious actors.
[gossipsub](https://github.com/libp2p/specs/blob/master/pubsub/gossipsub/gossipsub-v1.1.md) looks like a good protocol for this.

Matrix is a communications network.
It has a client-server, server-server decentralized architecture.
Rooms are synced (eventually consistent) among all servers with clients participating in the room.
Matrix supports "Application Services", which are limited to funcion in a passive mode, meaning they only piggyback on top of the existing protocols.
Synapse, a Matrix server implementation, supports "Modules"
The Matrix devs recognize the need for a robust reputation system and are in pursuit of funding and development for that purpose.

# Excerpts from DeSciPubDAOArchit22July19PrintCut.pdf

# Validation pool termination
How do we want to handle this?
The validation pool specifies a duration.
We don't want to compute results until the end of this duration.
We're currently supporting anonymous voting.
With anonymous voting, we need to wait until the end of the vote duration,
and then have a separate interval in which voters reveal their identities.
For now, we can let anonymous voters reveal their identities at any time

Bench.totalReputation is a very important quantity, isn't it? Basically determines inflation for reputation.

Should availability registration encumber reputation?

- Is a particular availability stake amount required?
Currently we support updating the staked amount.
Seems like a soft protocol thing.
A given DAO can have a formula for deciding appropriate amounts.

The following was a code comment on `Business.submitRequest(fee, ...)`:
> Fee should be held in escrow.
> That means there should be specific conditions under which the fee will be refunded.

> There could be separate thresholds to indicate the earliest that the job may be cancelled,

# Implementing forum
Does the following make sense?
We will link the forum to the bench
An author of a forum post /_ ? is always? can be? _/ a reputation holder.
This is what we call a expert. Let's update that terminology to be `reputationHolder`.
That's too long, though. Let's rename it to `expert`.
So we want to aim for the situation where the author of a forum post is an expert.
For now let's try thinking of them as experts no matter what;
The strength of their expertise is meant to be represented by reputation tokens.
So each reputation token must be a contract.
Minting a reputation token means to construct an instance of such a contract.
The reputation contract then has its own lifecycle.
We can support dynamic reevaluation if the reputation contract
- has an interface that allows (securely) updating
- Define secure :: passes validation pool
- How shall it know the operation is occurring as part of an "official" validation pool?
It can verify a signature...

what is reputation?

for now, combine c2 and c3

then send that to the forum to distribute.

The communication protocol(s) among network nodes
Each communication protocol among network nodes
has its own purpose
has its own assumptions, expectations, requirements, constraints
I think it makes sense to identify the constraints for our protocols.
We need the general public to be able to reliably
- Query information about the reputation WDAG
- Submit requests and fees for work
- Obtain the products of the work submitted by forum experts
Suppose we want only the requestor to be able to access a given work product.
(Why might we want this?)
Then the (soft) protocol for reviewing the work product would consist of
validating a signature by the requestor, attesting to their acceptance of the work product.
Alternatively access could be permitted to some group, such as reputation holders (a.k.a. experts).
Otherwise, for maximum utility, we would want to make the work products available indefinitely, as valuable artifacts.
Value here can be equated to the expected fees that the work products will help attract, which can in turn be equated to
reputation awarded to authors and reviewers of the work products.
Thus, the work of making the artifacts available must be funded.
The work of participating in a gossip / forum node consensus protocol and validating forum chain blocks must also be funded.
Suppose we have a storage contract.
- There can be a market for specific pledges of storage.
- buy: (amount, duration, price)
- sell: (amount, duration, price)
- Governance: Management of storage price
- may negotiate via loose -> tight binding traversal forum post sequence
- reputation in accordance with majority opinions on price parameters
- Verification of storage must occur by (randomly) querying the storage nodes and validating their responses.

Reputation Tokens
Minting
Suppose it's possible to mint a reputation token.
Say we have a contract that keeps track of all the reputation tokens.
Suppose the reputation contract implements ERC720 (NFT).
Assume a validation pool always corresponds to a post.
A single token could be minted for each validation pool.
That token could be subdivided so that each winning voter gets some.
Perhaps voters get tokens that are specifically identifiable as governance reputation tokens.
Then the main token can be awarded to the post author.
Each token should carry a specific value.
The forum will update the value of the token for the post author as well as posts affected by its chain of references.
Then, when participants wish to stake reputation (for voting or for availability),
they must specify the amount and the token address which carries that reputation.
The token should probably then lock that reputation, preventing it from being staked concurrently for another purpose.
Perhaps our interface can allow staking reputation from multiple tokens at the same time.
And/or we can provide a mechanism for consolidating tokens.
Or maybe, if reputation is staked via a given token, then the reputation awards should go to that same token.
In that case, when should new tokens be minted?
Maybe a token should be minted for each validation pool, but not subdivided.
Voter rewards can just add value to the existing tokens from which reputation was staked.
Maybe a new token should only be minted if the author did not provide a token from which to stake reputation on their own post.
This supports the case of a new author earning their first reputation.
In that case the author may need to pay a fee to buy in to the DAO.
Or perhaps they can be sponsored by one or more existing reputation token holders.
Existing reputation holders could grant some reputation to a new member.
Perhaps there could be a contract that allows sponsoring a new member, such that whatever fee is given,
that fee will automatically be repaid from the new member's earnings, before the new member starts receiving their share of earnings.
This could be a multi-party action, or could just be a generic operation that can be performed multiple times.
However, this effectively allows buying reputation, which goes against the core concept of reputation as evidence of performance.
It could make more sense for new members to submit some sort of petition, i.e. to make a post.
Maybe rather than submitting fees, existing members can grant some of their own reputation to a new member, and receive some sort of compensation if the new member does well.
So far the only workable model seems to be the idea that a new member must submit a post along with a fee, in order to be considered, and if the post is approved, they gain their first reputation.
The amount of this fee can be up to the applicant, and/or can be regulated by soft protocols within the DAO.
If this is the only scenario in which new rep tokens are minted, and from then on their value is updated as a result of each validation pool,
then we probably want each token to store information about the history of its value.
At a minimum this can be a list where each item includes the identifier of the corresponding validation pool, and the resulting increment/decrement of token value.
Each validation pool can then keep a record of the reputation staked by each voter, and the identifier of the corresponding post.

Matrix uses rooms to establish contexts.
We can have a forum context,
wherein a few things happen.
One is that the forum will have a root post; equivalently, any post can be the root of a forum.
The context of that post can be preserved.
The forum is thus a collection of posts. Each post MAY have its own internal structure.
A post MAY "replace" a prior post. This consists of on-chain and off-chain elements.
On-chain, a new post replaces a prior post.

> Users may also store arbitrary private key/value data in their account - such as client preferences, or server configuration settings which lack any other dedicated API. The API is symmetrical to managing Profile data.
> The client-server API allows clients to send messages, control rooms and synchronise conversation history. It is designed to support both lightweight clients which store no state and lazy-load data from the server as required - as well as heavyweight clients which maintain a full local persistent copy of server state.

This system is meant to represent a body of experts receiving fees to perform work.
Experts register their availability to receive work via the availability contract.
Request and associated fees are sumbitted via the business contract.
Evidence of the work performed is submitted as a post to the forum.
A successful validation pool ratifies the post.
Reputation is minted and distributed.
Fees are distributed.
What if we want the work to be block production for a blockchain?
Then to perform this work, an expert will need to participate in a communications network
such that they can confidently arrive at a majority view of each block.
Or else must at least be able to attest that a proposed block is valid,
meaning that it
- does not conflict with what the node believes to be the majority view
- includes what the node believes must be included according to the majority view
note that with this scheme there be muliple possible valid proposed blocks.
In any case, block production will require some form of consensus protocol. (BFT).
We have to define an algorithm from the perspective of a single node.
That node will need to make certain assumptions. Let us identify those assumptions.
- continuity guarantees?
- sender identifiability?
- it needs to bo possible to verify an asymmetric signature
This leads us to the storage requirements for a node.
For a node to exist, it must be capable of at least some temporal continuity.
That's what distinguishes a node from a client.
We want our protocol to involve performing certain kinds of work.
- Block production
- Messaging protocol
- In-memory storage
- Queryable history
- Fast record storage
- Archival record storage
What is common among these?
- Availability stake represents commitment to perform the specified work
- Peers must validate the work product via validation pool
How can we adapt the following concepts?
- Business contract interfacing with availability contract
- Reputation is minted via validation pools
- Reputation is rewarded to validation pool winners
- Reputation is awarded to a post in the forum
- Reputation is propagated via citations
In a messaging system, the work is
- Listening for messages
- Receiving messages
- Processing messages
- Sending messages
- Maintaining context related to incoming messages for the duration of some operation
- Performing computations
The work of verifying peers in a messaging system is
- Detecting invalid messages
- Successfully defending against DoS attacks
- Initiating validation pools?
- Voting in validation pools?
The work of providing a storage service extends that of participating in a messaging system.
- Storing data
- Retrieving data
The work of verifying peers work products in a storage network is
- Periodically querying peers and verifying their responses
- Participating in validation pools to police peers
- Initiating validation pools
- Voting in validation pools
Governance of a storage network includes
tuning post and validation pool timing and other parameters.
This can be served via the forum and validation pool,
by having the clients agree on an interpretation of the forum,
such that clients can derive from forum posts, at least some operating parameters.
It may even be possible to use the forum to provide the client code itself,
or tools for generating such code.

We are trying to build the reputation mechanisms for the X-prize project.
This project has the loosely stated goal of building tools for communities, but there is an expectation that this will use "MVPR."
My thinking is that the following basic features are needed of reputation:
- Bootstrap initial members
- Members can onboard new members
- Members can perform actions that affect each other's reputation
- Members can vote to prioritize content
- Public can view prioritized content
We need to provide detailed workflows for each of these.
# Bootstrap initial members
# Members can onboard new members
- A non-member is equivalent to a member with no reputation.
- Non-members can post and have their posts reviewed in order to gain reputation.
# Members can perform actions that affect each other's reputation
- Members can positively/negatively cite posts (what kind of posts?) by other members
- Stake reputation on these posts
- Validation pool determines the outcome - poster may gain or lose reputation,
- strength of effect can be influenced by ratio of upvotes
- Upvote = Post?
- Upvote = Vote in validation pool?
- Multiple types of reputation?
- Correctness
- "Goodness"
- Humor
# Members can vote to prioritize content
# Public can view prioritized content

* https://forum.openzeppelin.com/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* The default value of {decimals} is 18. To change this, you should override
* this function so it returns a different value.
*
