It has been anoft-cited examplethatEthereumcan be utilized to create a “decentralized Uber,” and there have beenseveral(as-yetunsuccessful) makes an attempt to do exactly that. But what does making a decentralized Uber really entail? In this publish, I suggest ) Ethereum is overkill for the duty at hand, and b) decentralized Uber will not be as horny because it sounds, and should or might not really make sensein the actual world.

What Uber Is Today

Uber is a enterprise that bundles a number of companies collectively to create a seamless transportation utility:

  • Technology growth.Uber employs engineers and designers to make it possible for all of Uber’s know-how works to their requirements, together with server- and client-side functions for drivers and passengers. Uber additionally does R&D to checknew business models, newapp features, and newproducts.
  • Order matchmaking.When folks press the button on their Uber app to catch a cab, their GPS location is broadcast to Uber’s servers the place the order is algorithmically matched with a driver whose personal Uber app can also be broadcasting their GPS location to Uber’s servers. Once the order is matched and the driving force accepts the order, the driving force is instructed the place the passenger is situated. The passenger may also see the place the driving force’s automotive is at and comply with their motion to the passenger’s location. Both are offered a communication hyperlink to one another through a proxy cellphone quantity to allow them to resolve any points whereas the driving force is en route to choose up the passenger.
  • Payments.Once the trip is over, credit score/debit card funds are processed by way of the Uber utility utilizing a third-party cost processor known as Braintree, a subsidiary of PayPal.
  • Insurance.While drivers are required to hold their very own legitimate insurance coverage with minimumcoverage quantities, Uber additionally supplies an umbrella insurance coverage coverage that covers any gaps whereas passengers are using within the car. Insome states, corporations like Uber and drivers that use their community are mandated by regulation to hold an insurance coverage coverage that meets sure minimal protection ranges.
  • Quality management.Uber checks to ensure drivers have a sound driver’s license, runs background checks to ensure drivers shouldn’t have a violent prison historical past or a poor driving document, confirm that drivers have legitimate insurance coverage with sufficient protection, and monitor each driver and passenger rankings to make sure that high quality requirements are being met by members of Uber’s community.
  • Customer service.If the driving force or passenger has a major problem with the transaction, they’ll escalate the difficulty to Uber customer support for decision. Customer service can also be accountable for following up if the driving force or passenger experiences a forgotten merchandise within the car.
  • Ancillary benefitsand companies.In addition to all of the core companies talked about, Uber additionally makes use of its scale and reachto negotiate bulk reductions on many ancillary companies for drivers corresponding to healthcare, automotive upkeep, cellular phone plans, and different services. Uber helps drivers acquire car financing in order that they’ll purchase a automotive to drive for Uber, and likewise lobbies governments to enact insurance policies which are favorable for Uber (and often, by extension, drivers and passengers) or oppose insurance policies that aren’t favorable.

What Decentralized Uber Is Not

Decentralized Uberis noteverybody broadcasting their location onto a blockchain and getting matched up by algorithmic oracles primarily based on location proximity and bidding on the perfect value for a trip.

  1. Putting folks’s present location and vacation spot on a public blockchain is dangerous for privateness and private safety. Peoplealready get upsetafter they’re confronted with the conclusion that Uber can monitor all of its customers in actual time.
  2. Putting folks’s present location and vacation spot and bids for fares on a public blockchain doesn’t scale effectively and might be actually costly.
  3. Ridesharing is an inherently native service, so orders don’t have to be broadcast to the entire world.
  4. Bidding for fares is an idea tried by thefailedridesharing startup Sidecar and has confirmed so as to add an excessive amount of friction to the method. It can also be an inherently completely different mannequin than the intentional simplicity of Uber’s “press one button to hail a cab” mannequin.

In brief, Ethereum will not be wanted to construct a decentralized Uber as a result of most consumer interactions ina decentralized Uber app would occur off-chain, and Bitcoin helps all of the on-chain interactions wanted at present.

What Decentralized Uber Could Be

Decentralized Uber ?’“ let’s name it “Doober” ?’“ is anunbundledUber, with the likelihood for redundancy in some areas to stop there from being a central level of management or failure. Different corporations can every be used for app growth, background checks, GPS monitoring, insurance coverage, matchmaking, funds, customer support, and extra advantages and companies, after which aggregated along with the Doober app. These companies couldbe re-bundled the place it makes financial sense to take action, thoughit is feasible manyparts of the system will stay decentralized for financial or sensible causes.


The blockchain is certainly a key part of the Doober utility, however not in the way in which that has been beforehand envisioned. Doober makes use of the blockchain just for identification and funds, delegating the duty of order matchmaking to a community of personal servers known as Matchmaker servers. Drivers and passengers can then select which servers they belief with their location information.

Blockstackis a key-value retailer database that makes use of the blockchain as a decentralized mechanism for figuring out the order of database updates. Think of it like a worldwide file listing with a trusted root within the blockchain e.g. or Blockstack is the glue that bindsall of ourunbundled companies collectively in a decentralized approach the place the consumer stays in management.

Blockstack could be used to register a novel identification on the blockchain ?’“ known as a “blockchain ID” ?’“ and hyperlink that identification to: public keys for message authentication and encryption; fame rankings from different drivers and passengers; official endorsements for statements like “I have a valid driver’s license,” “I have valid insurance with this much coverage,” “I do not have a violent criminal history,” and many others; and a hyperlink to a GPS API endpoint ?’“ all of the elements wanted for a Decentralized Uber-like system.

HowDecentralized Uber Could Work

  1. Register a blockchain ID like “” then hyperlink the blockchain ID to the Doober utility.
  2. Link a public key, known as an “ID Key,” to the blockchain ID and use the corresponding non-public key to signal and decrypt messages linked to the blockchain ID. This is how messages from the blockchain ID proprietor are authenticated. The ID key will go into Blockstack like
  3. Have an identification verification service signal tokens indicating that the one who controls theblockchain ID has offered proof of a sound driver’s license, insurance coverage with ample protection, and no historical past of violent conduct or automotive accidents. Link these tokens to the blockchain ID. These tokens will go into Blockstacklike
  4. Register for a novel GPS API endpoint service with the blockchain ID and hyperlink the distinctive GPS API endpoint to the blockchain ID. This endpoint will go intoBlockstacklike
  5. Register an account with a Matchmaker server. The account might be linked to the blockchain ID and is authenticated with the ID Key. Each Matchmaker can have completely different insurance policies relating to driver and passenger necessities e.g. background checks, insurance coverage, minimal fame rankings, and many others. Drivers and passengers canregister with a number of Matchmaker servers, and servers might federate for redundancy and scale. Userswill give permission to every registered Matchmaker to entry the consumer’s GPS location solely when the Doober app is on and ready to provide or obtain a trip.
  6. Passengers can broadcast orders to a number of servers on the identical time. If an order is matched on a number of servers, then the shopper can both manually choosewhich order they need to decide to, or they’ll set automated insurance policies to choosefor them. Drivers will then get pinged by the Matchmaker server(s) after they get a trip request, and might settle for or deny the request.
  7. Payments can happen on-chain or (extra doubtless) utilizing a Layer 2 system just like theLightning Network. The Matchmaker or different pre-determined arbitrator might be a signatory on a multi-sig transaction between the driving force and passenger to stop both from getting ripped off. Of course, they might additionally use another agreed upon cost technique.
  8. Issues are resolved both by insurance coverage corporations or Matchmaker customer support (or each, or another third celebration ?’“ this will all be negotiated manually or mechanically beforehand through the Doober app). Matchmaker servers can dealer fame exchanges and hold monitor of the whole fame historical past to make sure that high quality requirements are met. Drivers and passengers can hyperlink their fame historical past to their blockchain ID in order that it’s simply moveable. If the fame score of a driver or passenger falls under a pre-determined threshold, the Matchmaker can droop or deletetheir account. Matchmaker servers can gossip the fame rankings of blockchain IDs with different Matchmaker servers to assist stop hit-and-run/exit scamscenarios.

As you’ll be able to see, there are fairly a number of steps concerned, however actually not that mcuh greater than is concerned with signing up for Uber at present. Whether decentralizing Uber like that is value the additional friction for purchasers or really solves any actual issues is up for debate.

I believe there’s worth in giving peoplemore selection about who they share their information with, and breaking peopleout of silos and proprietary networks provides them extra leverage to regulate their on-line relationships. The proven fact that there may be redundancy between Matchmaker servers through federation might make the Doober community extra resilient in opposition to censorship in jurisdictions that shouldn’t have a good view of corporations like Uber. Then the targets of regulators should be drivers and passengers as a substitute of massive companieslike Uber, the identical approach end-users of BitTorrent are the goal of copyright enforcement as a substitute of BitTorrent Inc. Is it is a good factor or a foul factor? Maybe time will inform.

Anyways, that is how I might decentralize Uber.
