      "title": "Token Models - Grid+",
      "body": "# Grid+\n\nIn my [previous post](http://pitchandrolls.com/2017/10/04/analysing-token-models/) I stated I would try to learn more about token models and the associated technology by investigating crypto companies. First up a company called [Grid+](https://gridplus.io/).\n\nGrid+ aims to be a utility provider that exposes its customers to wholesale electricity prices. I really like their [blog posts](https://blog.gridplus.io/), they put a lot of effort into explaining the thought process behind the company. One of the co-founders, Alex Miller, actually encourages criticism and I think his transparency is refreshing. They’re one of the few companies who actually go into details about how blockchain technology can be used in a real life business and reading their posts really helps to develop my understanding of this technology.\n\n## Grid+ Value\n\nFirst up it’s useful to look at what value Grid+ can potentially bring to a customer.\n\nGrid+ want to expose its customers to wholesale electricity prices. Traditional utilities use fixed prices which are not market driven but wholesale prices vary throughout the day. Grid+ will offer prices both for consumed and generated energy based on the wholesale price (with a relatively small markup for most customers). This means customers have the opportunity to buy electricity when it is cheap, store it in batteries and sell when the price goes up. To me that’s pretty cool by itself.\n\nThe plan is to operate using the existing grid infrastructure. In theory thats a smart way to save costs, especially to start-up. From the description of how the system will work (see more detail at the end) I wonder if this might potentially restrict them.\nThey place a lot of emphasis on giving their users ‘[agency](https://blog.gridplus.io/grid-3-user-agency-and-iot-identity-ce36239b9e2b)’ which means users control the sending of funds, etc. In this system there is minimal human administration and minimal credit risk. Ultimately this keeps the price low for customers by avoiding traditional costs associated with admin, etc.\n\nAn IoT ‘Agent’ device is used to automatically handle payments via the Ethereum network. The goal is to create a p2p market between Grid+ agents. A customer who has electricity to sell can offer it at a local rate lower than the nearest wholesale rate. They will get bought out by another customer with the two customer Agents handling payments via a Grid+ hub on the Raiden network.\n\nGrid+ acts as the bridge between the old world of traditional energy suppliers and the new world of prosumers and p2p transactions.\n\nThey also have ambitions to make the Agent ‘smart’ to help the customer purchase the cheapest electricity possible. The Agent can be connected to other sensors such as thermostats, it will then predict energy usage and save money on energy purchasing.\nUltimately these are all potentially smart ways to provide cheaper electricity to the customer.\n\n## Tokens\n\n### Grid+ Tokens\n\nGrid+ will operate with a two-token model, a BOLT token and a GRID token.\n\nThe BOLT token will be treated by Grid+ as a stable-coin, redeemable by Grid+ customers for $1 worth of energy from Grid+ and backed by USD deposits.\n\nThe GRID token will allow Grid+ customers to purchase electricity from Grid+ at wholesale price. 1 GRID token = 500 kWh at the wholesale price.\n\n### Token Evaluation\n\nWorking through the twenty questions proposed by William Mougayar in Tokenomics — [A Business Guide to Token Usage, Utility and Value](https://medium.com/@wmougayar/tokenomics-a-business-guide-to-token-usage-utility-and-value-b19242053416) really helps to think about how the tokens are used:\n\n| Question       | BOLT         | GRID |\n| ------------- |:-------------:| :-----:|\n| Is the token tied to a product usage, i.e. does it give the user exclusive access to it, or provide interaction rights to the product?     | Yes, Provides access to Grid+ energy.| Yes, 1 GRID token = 500 kWh at the wholesale price.|\n| Does the token grant a governance action, like voting on a consensus related or other decision-making factor?|\tNo|\tNo|\n|Does the token enable the user to contribute to a value-adding action for the network or market that is being built?|\tYes, Selling generated electricity on a p2p network.|\tNo |\n|Does the token grant an ownership of sorts, whether it is real or a proxy to a value?\t|Yes, Ownership of energy.|\tYes, Ownership of wholesale energy.|\n| Does the token result in a monetizable reward based on an action by the user (active work)?\t|Yes, Any revenue earned by a customer from selling electricity is earned in BOLT tokens instead of fiat and is stored on the Agent.|\tNo|\n|Does the token grant the user a value based on sharing or disclosing some data about them (passive work)?\t|No\t|No|\n|Is buying something part of the business model?\t|Yes\t|Yes|\n|Is selling something part of the business model?\t|Yes\t|No|\n|Can users create a new product or service?\t|No\t|No|\n|Is the token required to run a smart contract or to fund an oracle?|\tNo\t|No|\n|Is the token required as a security deposit to secure some aspect of the blockchain’s operation?\t|No\t|No|\n|Is the token (or a derivative of it, like a stable coin or gas unit) used to pay for some usage?\t|Yes, Pay for used electricity.|\tNo|\n|Is the token required to join a network or other related entity?\t|Yes, Can't join Grid+ network without token.|\tNo|\n|Does the token enable a real connection between users?\t|Yes? Allows p2p payments between users.|\tNo|\n|Is the token given away or offered at a discount, as an incentive to encourage product trial or usage?|\tNo|\tYes, I think it incentivises people to start using Grid+.|\n|Is the token your principal payment unit, essentially functioning as an internal currency?\t|Yes\t|No|\n|Is the token (or derivative of it) the principal accounting unit for all internal transactions?\t|I think this is a yes although it may be kW instead.\t|No|\n|Does your blockchain autonomously distribute profits to token holders?\t|Yes, Agents are automatically updated.\t|No|\n|Does your blockchain autonomously distribute other benefits to token holders?\t|Yes. Also possibly Casper, etc?\t|No|\n|Is there a related benefit to your users, resulting from built-in currency inflation?|\tNo\t|No|\n|**Total**|**13/20**|**4/20**|\n\nWhich leads to the conclusion that the tokens offer the following utility:\n\n**The Value Exchange**\n\nThe BOLT token is a unit of value that allows the buying and selling of energy between Grid+ and users and also user to user.\nUsers can also earn BOLTS by generating and selling electricity or by arbitrage.\n\n**The Toll**\n\nIt’s obvious that the BOLT token is used to pay for electricity used but I feel like I’m not 100% on this one. Maybe it’s because a token isn’t essential for this function. In the [User Agency](https://blog.gridplus.io/grid-3-user-agency-and-iot-identity-ce36239b9e2b) post Alex does admits this part could be done using a traditional infrastructure.\n\n**The Function**\n\nAs far as I can see the GRID token is mainly for. It is offering a discount that encourages users to use Grid+ services.\n\n**The Currency**\n\nTraditional payment processing fees and admin costs are reduced.\n\np2p payments are made economically and technologically viable.\n\n## Conclusions\n\nI’m not sure if 13/20 is considered a high score but my feelings are the BOLT token utility more than proves itself essential to the business model.\n\nInitially I was sceptical about the use of the GRID token but after working through the questions I can see it’s potentially a really nice way to incentivise people to start using the service.\n\nThere are also some other interesting opportunities described in the post [Casper, Plasma, and the Grid+ Agent](https://blog.gridplus.io/casper-plasma-and-the-grid-agent-944c324a1b69) that demonstrates the Grid+ team are super innovative when it comes to using blockchain technology and are still exploring new ideas — it must be a cool place to work! I think the last paragraph from Alex Millers [The P2P Grid We All Want](https://blog.gridplus.io/the-p2p-grid-we-all-want-d7b1b923f02c) post demonstrates this:\n\n> However, this brainstorming session is likely an exercise in futility because the future is always uncertain and we’re talking about a future that is likely a decade or more away. Nevertheless, we at Grid+ are primarily motivated by bringing forth the future of energy. If Grid+ is so successful that our customers eventually dis-intermediate us and we really have no way to make money, then perhaps we’ve accomplished what we set out to do. We as a team would be happy with an outcome that empowers the people and establishes a new, transactive grid because that would mean we will have proven the power of decentralizing technologies — as far as we’re concerned, that’s a win for humanity.\n\n## How Grid+ Will Work\n\nThe following isn’t actually that relative from the token model perspective but it’s really interesting to see the nuts and bolts of how a crypto company could function. Really cool of the Grid+ to share this.\n\nA customer purchases an agent (a small device capable of making signatures) and claims that device based on a serial number printed on the box.\n\nBefore shipping the agent Grid+ whitelist its serial number on their registry contract.\n\nGrid+ map that serial number to an Ethereum address, which is a function of its public key.\n\nAgent Address — Created when device first boots up.\n\nOwner Address — customer who enters the serial number printed on the device into the Grid+ web console.\n\nCustomers will make a refundable initial deposit then will prepay each month.\n\nFiat payments will be converted to USDX tokens.\n\nEvery few hours Grid+ request payment from a customers agent commensurate with the amount of energy used.\n\nIf the customer exceeds her monthly allowance (or her agent simply doesn’t pay), the customer will be notified deductions are made from her initial account deposit.\n\nyour utility company tracks how much power goes into your house and how much power goes out of your house and then sends you a bill based on the net result.\n\nSmart meters send data to ISO. ISO makes data available via API.\n\nGrid+ will query the ISO (ERCOT in Texas) and bill customers’ Agents based on that usage.",

      "title": "IOTA & Python - A Beginning",
      "body": "## Intro\n\n> IOTA is a revolutionary new transactional settlement and data integrity layer for the Internet of Things. It’s based on a new distributed ledger architecture, the Tangle, which overcomes the inefficiencies of current Blockchain designs and introduces a new way of reaching consensus in a decentralized peer-to-peer system. For the first time ever, through IOTA people can transfer money without any fees. This means that even infinitesimally small nanopayments can be made through IOTA. - [From the docs](https://iota.readme.io/v1.2.0/docs)\n\nSounds pretty cool! And I think it has potential to overcome some existing blockchain issues. I wanted to try out some development using Python and IOTA Python. It took a bit of work getting started but once you know the steps it's pretty easy so I thought I'd share what I did.\n\n## Setup Dev Environment\n\nIt's always good practise to develop using a virtual environment so I started in a clean dir and ran:\n\n````\nvirtualenv env\n````\n\nAnd then activated the environment:\n````\nsource env/bin/activate\n````\n\n## Install PyOTA\n\n[PyOTA](https://github.com/iotaledger/iota.lib.py) is the official Python library for the IOTA Core and implements the [official IOTA API](https://iota.readme.io/).\n\nIn your activated dev environment install the pyota library using:\n```\npip install pyota\n```\n\n\n## Full Nodes, Light Clients, Adapters & Routing \n\nAn IOTA full node connects to the tangle to share data with other nodes, it also takes care of Proof Of Work (PoW).  It's possible to interface with a running node through port 14265 using [API calls](https://iota.readme.io/docs/getting-started).\n\nSome resource restricted devices will not be able to act as a full node. These can run a light client and connect to a remote IRI instance which takes care of some of the more intensive overhead. Using a light client also makes getting started easier as you don't have to worry about connecting to neighbours and static IP addressing.\n\nPyOTA doesn't yet have PoW integrated, so requests like [attachToTangle](https://iota.readme.io/docs/attachtotangle) need to be offloaded to a full IOTA node. Normally you would want a full node to sync with the network which means you need to pair with neighbours but because I don't have a static IP address this is tricky. \n\nTo overcome this it's possible to use PyOTAs Adapter Routing Wrapper. Adapters are responsible for sending requests to a node and returning the response. The RoutingWrapper allows you to route API requests to different nodes depending on the command name. \n\nSo now PoW commands can be routed to a locally running full node which doesn't have to be synced because everything else can be routed to a remote IRI. Very handy!\n\n\n## Install Local Full Node\n\nNext I installed the IRI - the IOTA Reference Implementation. It's a complete IOTA node so can take care of PoW. As mentioned in the last section I'm not worried about syncing this node so don't need to worry about finding neighbours.\n\nThe source code for the IRI can be found [here](https://github.com/iotaledger/iri). I installed it by downloading an official release of a jar file, in my case iri-1.2.4.jar, from [this location](https://github.com/iotaledger/iri/releases).\n\nOnce downloaded it can be started using:\n\n````\njava -jar iri-1.2.3.jar -p 14265\n````\n\n\n## Send Example\n\nNow we can bring it all together by using the extended API call, [send_transfer](https://github.com/iotaledger/wiki/blob/master/api-proposal.md#sendtransfer), to make a transaction.\n\n```Python\n# coding=utf-8\n\"\"\"\nSimple example using the RoutingWrapper to route API requests to different nodes.\nSee: https://github.com/iotaledger/documentation/blob/iota.lib.py/1.2.x/source/includes/_adapters.md#routingwrapper\n\"\"\"\nfrom iota import *\nfrom iota.adapter.wrappers import RoutingWrapper\n\napi =\\\n  Iota(\n    # Send PoW requests to local node.\n    # All other requests go to light wallet node.\n    RoutingWrapper('http://service.iotasupport.com:14265')\n      .add_route('attachToTangle', 'http://localhost:14265'),\n\n    # Seed used for cryptographic functions.\n    seed = b'SEED9GOES9HERE'\n  )\n\n# Example of sending a transfer using the adapter.\nbundle = api.send_transfer(\n  depth = 100,\n    transfers = [\n      ProposedTransaction(\n        # Recipient of the transfer.\n        address =\n          Address(\n            #b'TESTVALUE9DONTUSEINPRODUCTION99999FBFFTG'\n            #b'QFWEHEL9KCAFXBJBXGE9HID9XCOHFIDABHDG9AHDR'\n          ),\n\n        # Amount of IOTA to transfer.\n        # This value may be zero.\n        value = 1,\n\n        # Optional tag to attach to the transfer.\n        tag = Tag(b'ADAPT'),\n\n        # Optional message to include with the transfer.\n        message = TryteString.from_string('Hello!'),\n      ),\n    ],\n)\n```",
