The company claims to be working on a 7nm flagship miner which will ship by the end of 2019, just as miners prepare for the mid-2020 halving. Critics wonder how Bitmain can reproduce the success of the S9 without the company's original chip designer.
Inside the rise and fall (and rise?) of crypto mining giant Bitmain
"Bitmain’s new CEO has the difficult job of leading a divided firm, after failed IPO and mass lay-offs. The company hopes that next bitcoin halving in 2020 will spur demand for its yet-to-be launched 7nm-chip miners. The world’s biggest cryptocurrency mining company is going through tough times. But a code change in bitcoin might come to the rescue, again."
A simple on-boarding to bitcoin
"So I thought to myself, a materials engineer who is often asked how he became interested in the 'blockchain space' — why not write up a few reasons I think bitcoin is fascinating and follow it up with some information I would’ve loved to have known when I went through on-boarding myself. Here’s just a bit of what I have to say. ... Having said all that, bitcoin is an incredibly interesting experiment in systems thinking, touching on and inter-relating more subject areas than anything I’ve encountered before. For this reason, I simply can’t get enough."
The ETF Tax Dodge Is Wall Street’s “Dirty Little Secret”
"One day last September an unidentified trader pumped more than $3 billion into a tech fund run by State Street Corp. Two days later that trader pulled out a similar amount. Why would someone make such a large bet—five times bigger than any previous transaction in the fund—and then reverse it so quickly? It turns out that transfusions like these are tax dodges, carried out by the world’s largest asset managers with help from investment banks. The beneficiaries are the long-term investors in exchange-traded funds. Such trades, nicknamed “heartbeats,” are rampant across the $4 trillion U.S. ETF market, with more than 500 made in the past year. One ETF manager calls them the industry’s “dirty little secret.”"

Libra: Succinct Zero-Knowledge Proofs with Optimal ProverComputation
"We present Libra, the first zero-knowledge proof system that has both optimal prover time and succinct proof size/verification time. In particular, if C is the size of the circuit being proved (i) the prover time is O (C) irrespective of the circuit type; (ii) the proof size and verification time are both O (dlogC) ford-depth log-space uniform circuits (such as RAM programs). In addition Libra features an one-time trusted setup that depends only on the size of the input to the circuit and not on the circuit logic. Underlying Libra is a new linear-time algorithm for the prover of the interactive proof protocol by Goldwasser, Kalai and Rothblum (also known as GKR protocol), as well as an efficient approach to turn the GKR protocol to zero-knowledge using small masking polynomials. Not only does Libra have excellent asymptotics, but it is also efficient in practice."

Bitcoin Bear Market Diaries Volume 12 Marty Bent
"Make sure you understand the gravity that comes with a world in which Bitcoin succeeds. It is a disruptive force that could potentially be met by an opposing, coordinated force in the future. Be prepared for that reality. I believe wholeheartedly that Bitcoin will be a net positive for the world, but it will obsolete a lot of entrenched power in the process of accruing a massive amount of value, and that entrenched power may not be all too pleased about it."
