1/ a quick thread on protocols focused on location. location data is leveraged by many consumer services (Google Maps, Uber), but also by military and industrial applications. now teams are #blockchain-ing this data to make it tamper-proof (secure), verifiable, and trustless.
2/ furthermore, new applications like self driving vehicles, AI, and increasingly digitized consumer, industrial, and military services will rely on secure location information services to deliver service. example - in 2012, a military drone was hacked and "stolen" by students...
3/ several projects are working on a new form of consensus called "proof of location" to design new mechanisms for collecting, verifying, storing, and sending data about location to the services and applications that consumer this data. let's dig into proof of location.
4/ first you need devices to collect location data. various implementations of PoL rely on beacons of various types of gather x and y coordinates and assign location data to these geospatial coordinates using a system of stakeholder incentives via a token.
5/ you also need a z coordinate for time - and then you effectively have a space coordinate with a time anchor to provide an accurate assessment of geospatial network topology. if this sounds complicated, it is. i have limited experience with geospatial data and mapping...
6/ but i can fully appreciate the complexities of providing mission-critical location data in a secure, accurate manner. if you want to dig into these systems further, here are some projects to look into:
7/ FOAM (@foamspace) - a proof of location protocol that has been in development since 2017 (if not earlier). has a TCR to add, rank, and review locations. recently conducted a public token sale via @tokenfoundry to raise 38k ETH for development.
8/ Platin (@platin_io) - a proof of location blockchain with a focus on mobile-based computation via a phone app, and including zero-knowledge proofs to preserve privacy of data validators and contributors. conducting a token sale and airdrops in October.
9/ XYO Network (@XYOracleNetwork) - a cryptographic location network who have deployed over 1 million location beacons and claim the "single largest" network of Bluetooth & GPS devices in the world. note - they also have a sponsored race car.
10/ last but not least, @streetcredco - built by execs from MapQuest and Mapzen (a Samsung co), focusing on building "accessible data for places people care about." no specifics published yet, but you can earn #bitcoin by mapping locations in NYC -
11/ what projects have i missed? do we need new protocols with their own token for location data, or can we leverage #bitcoin for the incentive layer? anyone spending time on this space? recommended reading? i'm intrigued by this use case, but scratching the surface.

1/ let's talk about today's @MakerDAO / @a16z announcement. for those who missed it, A16Z's crypto fund bought 6% of Maker tokens for $15M, at a 25% implied discount to the current price of $MKR.
2/ according to a blog post, the $15M will be used to fund the next 3 years of operating costs. i'm sure people think this is a great sign for the project - being able to recruit high quality capital. but, i think this is a massive failure in governance and project management.
3/ no vote was conducted on this matter, despite governance being a core tenant of the project:

instead, a team decided to sell a large portion of tokens to one single investor without consulting other $MKR holders or communicating with their community.

1/ in markets, investor psychology is everything. i shared my thoughts on greed, investor psychology, shitcoin, and market cannibalization at @dezentral_io in berlin and wanted to share some of these ideas here...

option b: skip directly to slides here:…
2/ investors in the crypto ecosystem saw everything go up and to the right. everyone in the market is feeling good, and worth a lot on paper. everyone outside the market is feeling FOMO, and wants in on some juicy returns. the narrative is "blockchain, make me money!"
3/ everyone starts looking for the next #bitcoin, #ethereum, #ripple. people begin to believe that the market will go up and to the right forever, and investors flush with paper returns from the crypto casino rush to multiply their money at the shitcoin roulette wheel.

1/ decentralization is a myth. we use "decentralized" without any specificity as to what that *actually* means. let's untangle the idea of decentralization. i developed a basic grid that breaks it down at the protocol, network, and app layer (dated april 2018)
2/ a good chunk of the data comes from - the brainchild of @ummjackson - who was continuously harassed by some of the projects on his site that are... ummm... clearly not "decentralized" in any manner while marketing that narrative ad nauseum
3/ there are many different ways to view "decentralization" - @SarahJamieLewis wrote about this as well - great tweetstorm here

1/ security tokens may be interesting, but i think we are far from a world where there is demand for millions of tokenized assets. let’s dive into “why” - promise this will be fun 😈
2/ i’ve been spending the last six months deeply immersed in the institutional investor community. for simplicity, let’s say the US cohort of “institutional” investors - or the TAM - for tokens is $28 trillion in AUM. (ignore new demand creation)
3/ currently, these investors allocate to things like venture and hedge funds (15%), private equity (10%), real estate (20%), equities (30%), and the remaining 25% is commodities, debt, developing markets, FX, and cash.

1/ re-visiting Howard Marks' @Oaktree comments on liquidity, very relevant to crypto, and especially thinly traded or centrally owned, alts:

the key criterion [for liquidity] isn't "can you sell it?" it's "can you sell it a price equal or close to the last price?"
2/ liquidity is ephemeral. it can come and go. the liquidity of an asset often depends on which way you want to go... and which way everyone else wants to go. if you want to sell when everyone wants to buy, you're likely to find your position is highly liquid.
3/ if you want to sell when everyone wants to sell, you may find your position is totally illiquid;
selling may take a long time
require accepting a big discount
or both.
it's not illiquid or liquid; it's entirely situational.

1/ as you may already know, i love developing new frameworks around various matters in #crypto and drawing analogs to existing concepts in traditional finance (recovering consultant, I know 🙄)

my latest target: the @tezos experiment and token holder activism
2/ full disclosure: I'm a #tezos token holder and will be delegating my stake to the baking crew at @tezzigator (what up josh and bo)

Here's why:…

now what is "baking" you may ask? a great place to start it turns out.
3/ where #bitcoin has Proof of Work and mining, #Tezos has (delegated) Proof of Stake and baking. in tezos, “bakers" participate in consensus and earn the right to create blocks when a tezos "roll" (10,000 $XTZ) that they own or manage is randomly selected to create a new block
