# Eris

### Participatory Architecture for Social Scientists (and Everyone Else)

---

### Ideas Alone Are Not That Powerful

* 2008 -- Koyoto Protocol CDM + Kiva
* 2009 -- Aquaponics for Villages
* 2010 -- Uber for Veggies
* 2011 -- Picture This
* 2012 -- Clan Based Insurance Mechanism
* 2013 -- Smart Recycling
* 2014 -- The Dawn of the DAO..?

---

But **ideas** combined with a **vernacular** and **tools** can be very powerful indeed.

We empower developers to embrace participatory software architecture via distributed computing and smart contract systems.

---

In other words: we are a `devtools` shop.

---

### What is **Participatory Architecture**?

It is a method of designing software where the users of the application participate in the **operation** and **scaling** of the application via:

1. lending computational power to assist in data management
2. lending storage space to assist in content distribution

---

Using participatory architecture, distributed systems, and smart contracts, **complex ideas** become easier to study.

And to implement

---

What is a **Smart Contract**?

`A cryptographically provable execution of code`

---

![smart contracts intro](lib/img/smart-ks.png)

---

What is **Eris Industries** Building?

---

`a distributed application server -- distributed systems agnosticism with a harmonized actions layer`

---

`a distributed database management system -- blockchains for everyone`

---

### Scenario

> A group of social scientists is interested in researching some aspect of Universal Basic Income. The research will be collaborative and distributed among a dozen researchers across the globe.

---

#### Step 1: Get the Tools

```bash
go get github.com/eris-ltd/thelonious/cmd/monk
cd $GOPATH/src/github.com/eris-ltd/thelonious/cmd/monk/
go install
```

```bash
go get github.com/eris-ltd/epm-go/cmd/epm/
cd $GOPATH/src/github.com/ethereum/serpent-go
git submodule init
git submodule update
cd $GOPATH/src/github.com/eris-ltd/epm-go/cmd/epm/
go install
epm init
```

---

#### Step 2: Design Your Chain

* Transactors
* Creators
* Committers
* Doug-ers

---

#### Step 3: Create Accounts

We don't have a tool for this yet, but we will be building one soon.

Distribute the keys for the accounts to all of the participants.

---

#### Step 4: Build genesis.json (1/4)

```json
{
  "address": "0000000000THISISDOUG",
  "pdx": "",
  "doug": "",
  "unique": true,
  "private-key": "",
  "no-gendoug": false,
  "consensus": "",
  "difficulty": 15,
  "public:mine": 0,
  "public:create": 0,
  "public:tx": 0,
  "maxgastx": "",
  "tapow": 0,
  "blocktime": 0,
  "vm": null
}
```

---

#### Step 4: Build genesis.json (2/4)

```json
  "accounts": [
         {
                 "address": "0xbbbd0256041f7aed3ce278c56ee61492de96d001",
                 "name": "researcherA",
                 "balance": "1000000000000000000000000000000000000",
                 "permissions": {"tx":1,"mine":1,"create":1,"doug":1},
                 "stake": 0
         },
         ...
  ]
}
```

#### Step 4: Build genesis.json (3/4)

```json
  "accounts": [
         {
                 "address": "0xaaad0256041f7aed3ce278c56ee61492de96d224",
                 "name": "trustedParticipantA",
                 "balance": "0",
                 "permissions": {"tx":1,"mine":1,"create":0,"doug":0},
                 "stake": 0
         },
         ...
  ]
}
```

#### Step 4: Build genesis.json (4/4)

```json
  "accounts": [
         {
                 "address": "0xcccd0256041f7aed3ce278c56ee61492de96d445",
                 "name": "participantA",
                 "balance": "0",
                 "permissions": {"tx":1,"mine":0,"create":0,"doug":0},
                 "stake": 0
         },
         ...
  ]
}
```

#### Step 5: Deploy Your Chain

```bash
epm new --genesis ./genesis.json --name researchProjectUBI_A

2015/01/12 19:21:04 [EPM-CLI] Deployed and installed chain: thelonious/d144e0971c674bbc3b983b8cbb29660dcf0ca530
2015/01/12 19:21:04 [EPM-CLI] Checked out chain: thelonious/d144e0971c674bbc3b983b8cbb29660dcf0ca530
```

```bash
epm refs

Available refs:
researchProjectUBI_a     :       thelonious/d144e0971c674bbc3b983b8cbb29660dcf0ca530
researchProjectUBI_b     :       thelonious/a2f25e98b90410a132fa0e6f75f83b333bc9f2d7
researchProjectUBI_c     :       thelonious/15deb792e5577ed67bc39105001c8044720586e3
researchProjectUBI_d     :       thelonious/0eab6abd02e1a79e60cb96c3d63e70fac2c31f8c
```

---

#### Step 6: Build & Deploy Your Smart Contracts

```bash
epm deploy --chain researchProjectUBI_A
```

---

#### Step 7: Have Fun!
