Proof of Work #63
Greetings from Boston! I’ll be in NYC from the 10th to the 12th—I love meeting PoW readers, so if you’ll be around please feel free to reply to this! I’ll also be speaking very briefly at the Magical Crypto Conference on the 11th at 5:10 PM about Satoshi’s Treasure—if you’re a Hunter, it might be worth either showing up or sending a friend in your stead 👀
The first week of Satoshi’s Treasure has been absolutely incredible. The second set of clues were released on Sunday, and as before were solved much faster than we were expecting. Not only did hunters decipher all of the clues to get the Leporine Key, but they even identified the extremely obscure Chinese cult movie that one of the gif clues was from. It strikes me that we’ve accidentally assembled the beginnings of an army of the world’s most resourceful hackers and problem solvers…
In addition to explosive growth in the number of people playing, I’ve been especially stoked to see the number of people who are actually creating things. Fan sites with satellite transmissions, prediction market bets on which teams will perform well, a very full-featured Discord bot for team management, fan art, and more. A bunch of really solid developers are building on top of what we’ve made, and what’s cool about using cryptographic primitives for game is that they don’t have to ask us for an API key to do so—they can just do it! We’ve also pretty much taken over the Blockstream satellite and turned it into a one-way Satoshi’s Treasure chat room 😂.
The next clue with be released this Sunday, and the previous clues have all been publicly released (findable with some Googling) so if you haven’t started playing, now is a great time.
I’m reverting to the previous format on then newsletter cuz everyone seems to like it better. Highlights this week: Monero community releases a really nice PDF intro to the coin, Cosmos cleanly pulled off an upgrade, dYdX launched their mainnet product, MKR raised their stability fee to 14.5%, and Livepeer published a post on their probabilistic micropayments solution.
China & Asia Updates
No major news in mining this week. Many miners who stocked up on mining machines earlier this year have seen a decent return as prices start to rally. S9’s average price is now close to 2000 RMB ($250-300) vs 900 RMB ($120-150) at its lowest
Mining machines’ price beta is always greater than 1 compared to BTC’s price, and the risk is largely taken on by the buyer, not the seller
OKEx’s support for $BSV is mostly a relationship play between Jack Lu and Star Xu. Jack is the most well-known public $BSV supporter in the Chinse community and was a long-time OKEx veteran. He also overlapped with CZ (former OKEx CTO) between 2014-2015 as Head of International at OKEx
On-going game of musical chairs amongst Asian exchanges’ IEOs, and some drama during the recent Bibox IEO may signal the end of the IEO hype. Another fairly new exchange Biss.com, created a new model for a FOMO3D hybrid IEO. The IEO hype reminds me of last year’s transaction fee mining frenzy, which was also not sustainable because the model is easily reproducible. Both are like a game of musical chairs where each exchange hopes they’ll still have a seat when the music stops
Both Huobi and Okex are rushing to launch their public chains in Q2. Few details have been released from either side regarding the chains
India’s National Payments Corporation, a domestic bank consortium is said to be building a blockchain settlement rail for retail payments.
Rakuten Wallet might be one of the biggest things at the moment in the Japan crypto scene. It’s now open for web registration, only a month after it acquired a crypto license from the FSA. Regulatory cost in Japan is VERY high, and the FSA is extremely conservative when it comes to foreign players, hence why it is giving local fintech giants an unfair advantage over global crypto players like Binance and Coinbase.
According to a Korea local TV (Arirang) reports, over 7% over total Koreans (3.5 million) have bought cryptocurrencies with an average investment of $6000. To put this in context, the average Korean’s monthly income is about $3000, meaning those who made crypto investments are likely upper middle class. Another unconfirmed source (this statistic has been floating around since early 2018) claims that over 70% of Korean white collar workers have held cryptoassets at some point.
