kang··on How I became Leonardo da Vinci on the Blockchain
sorry, but blockchain should be compared to internet, not google & yes packet-switching took a decade to become TCP/IP and took more than 2 decades, to become the internet. Bitcoin should be compared to google.
kang··on How I became Leonardo da Vinci on the Blockchain
Blockchains don't work for digital assets either because there is no way to 'give' anything digital i.e., ensuring sender no longer has a digital copy
kang··on HashLife: An Algorithm for Compressing Space and Time (2006)
Memoization is borrowing time from the past, not bypassing/compressing it.
kang··on Ask HN: How to blog things I've learnt in graduate school?
This is one possible route - whichever topic or doubt you end up searching the internet for, make a small post about the solution. As you grow over time, start being more comprehensive about the solutions, and try to list information on the very niche topic till the periphery of human knowledge( from history of birth to bleeding edge tech in that area). Growing more over time you will start getting in-depth and at a zen blogger stage, cross-domain.

Or you could make the blog all about you. Your personal journey of how some attained knowledge in the past, you were able to apply.

kang··on Launch HN: Dharma (YC S17) an open protocol for borrowing/lending cryptoassets
The word dharma means one's duty according to their place in their cosmic order. Assigning it to sacred teachings of anyone is not correct. There is a word _dhammam_ in pali lang that is from around the area buddha lived, which has different meaning from dharma, is used to refer budhha's teachings.
kang··on The Verge Hack, Explained
One can always invent blockchain buzzwords like "Dark Gravity Wave" but even copying code requires understanding of algorithms.
kang··on The Verge Hack, Explained
This statement is against the spirit of HN. Although I agree that none of other pow coins currently have as robust code, but making an absolute statement like that is not rational.

You are saying every merge in the core code protocol is trusted by you even if that code has not even been written yet.

To think bitcoin is a database is laughable.

"solid track record"

Can you name one thing he built/invented that does anything? Beyond collecting bitcoin.

kang··on Ethereum Sharding FAQ
This comment is just wishful thinking and stems from a false fact. There are HNers who were using "blockchain" even before Vitalik knew about bitcoin.

There is no innovation happening. Distributed is not decentralized. Ethereum's blockchain is a mathematical proof of it being mutable (and thus not a blockchain?). Tell me any "dapp" and I will tell you the point of centralization. (Before you even mention it's probably 'the origin of money' )

kang··on Ethereum Sharding FAQ
Haha, “Vitalik’s project immediately before Ethereum is that he was collecting investments from people to fund building a computer program to solve NP-complete problems in polynomial time, supposedly by simulating a quantum computer."
kang··on Show HN: Tube – Minimalist YouTube
Few years ago there were sites like cull.tv and mox.tv that were really amazing interfaces for youtube. Its sad that now doesn't even exist a demo somewhere(?)

kang··on SBFT: A Scalable Decentralized Trust Infrastructure for Blockchains
"Permissioned" ledgers have existed and failed many times before the invention of bitcoin. This is not decentralized. None of the BFT protocols are.
kang··on India’s Central Bank Bans Regulated Entities From Dealing In Virtual Currencies
Indian governance is a mess right now. A govt sending a message like this while collecting tax in parallel from the same system is a contradiction to me.

To start with RBI needs to sit with IT dept. And please include some CS professors.

kang··on Gravitational attraction of stars and cows
The entire universe is having measurable("infinite" but countable) gravitational effect. You need to prove that "cumulative" effect is negligible.
kang··on Keybase is now supported by the Stellar Development Foundation
Stellar doesn't work.

Disturbed by energy consumption, their solution is to divide(shard) the blockchain graph. Does that result in a consensus though? Not in their own prior version.

Will the topology they are claiming emerge? There is no proof.

kang··on Launch HN: CoinTracker (YC W18) – Cryptocurrency portfolio and tax manager
The least we can say is satoshi's whitepaper lists eliminating financial intermediaries as the prime motive, in the first paragraph itself.
kang··on Launch HN: CoinTracker (YC W18) – Cryptocurrency portfolio and tax manager
Hello, congratulations on exposure. I would like to express a concern.

Being a cryptocurrency user is all about NOT paying taxes. As more people understand the systems of cryptoanarchy, more will the gateway business models fade-away(basically exchanges and add-ons like OP).

kang··on For first time a dedicated conversation on cryptocurrency in US congress
As you mentioned, since money trickling out cannot be prevented after this invention, a better bet for India and China is to incubate home projects that can attract foreign money and hope it is more than spending. People who spend more than the value they create for humanity, are doomed in long-term.
kang··on Governments Worry That Cryptocurrencies Could Be the ‘Next Swiss Bank Account’
One may adjust the 'centralised' in "decentralised" to include anything. In reality it is just BTC.
kang··on Governments Worry That Cryptocurrencies Could Be the ‘Next Swiss Bank Account’
Governments worry that those 'Swiss Bank Accounts' aren't exclusive anymore.
kang··on Waze Carpool
Vancouver is same in regards to the service but strangely the position-tracking of a bus is more accurate on mobile google maps than the official 'transit' app, although the former says the source of data is latter.
kang··on Blockchains from a Distributed Computing Perspective [pdf]
> a ledger is just an indelible, append-only log of transactions that take place between various parties.

Readers should decide either the above statement is true and ethereum is not a blockchain by that definition[0] or blockchain is just an abstract buzzword. Technology wise, git is as powerful as a blockchain at being an append-only log without the most important ingredient - proof-of work.

2. There is a whole section on private blockchains

Can you write one program using a private blockchain(for eg use ibm's hyperledger) that can't be written using git? Private blockchains, premined coins, colored tokens, assets etc all of them.

3. Regarding smart contracts, can you show me one use of turing completeness in a blockchain? If yes, ethereum is not turing complete practically cause gas.

4. How does one determine the gas price of an opcode in a network? How does ethereum do it? (i think only people understanding need of proof-of-work will understand this)

5. W.r.t the layers of OSI model, the need for smart contract is trivial. Show me one smart contract you can do 'in' a blockchain and I will tell you how to do it 'on' bitcoin.

kang··on Show HN: Collateralized Debt Agreements Using Smart Contracts and Virtual Cats
The 'underwriter' in dharma protocol is essentially current day middleman. You contradicted yourself by saying "trustlessly" in point 1 and then admitting to point 3. Point 2 is unenforceable without current legal system.
kang··on Show HN: Collateralized Debt Agreements Using Smart Contracts and Virtual Cats
Both the points and your third point about a centralized system being able to decentralize itself - I am saying all of them are impossible (given current knowledge - unless you have secret protocols...).
kang··on Show HN: Collateralized Debt Agreements Using Smart Contracts and Virtual Cats
I have looking deeply into lending smart contract protocols - dharma, ethlend, salt, paypie, etc. My biggest complaint is all of them are so-called 'blockchain' products but not only can they be done better without blockchain, but that despite their product being all about decentralization, none of these projects are decentralised!
kang··on Ethereum programming for web developers
This looks like the start of slockit conversation proposing a DAO
kang··on Ethereum programming for web developers
> The most natural follow-up to currencies on a blockchain are assets

Natural for marketing-team maybe but not for developers. They only seem natural because they both look like 'value' transfer. But there is a huge difference. The value in-case of currency-use is inherently generated using proof-of-work whereas there is no decentralised way to map a real asset to virtual token.

So NO, none of these 'assets on the blockchain' are decentralized or even need blockchain non-trivially.
