bitcoin: karnataka woos techies, organises blockchain hackathon


bengaluru: as blockchain -- the technology behind cryptocurrencies such as bitcoin -- is fast gaining acceptance worldwide, the karnataka government has taken the first step to see if it can be used in some critical areas of governance in the state. "there are problems that could be better solved using modern tools and technologies. we want to understand the blockchain technology itself, and see how we can use it to solve specific issues," information technology minister priyank kharge told et. towards this, karnataka's information technology department is organising a blockchain hackathon from january 19 to january 21 to see if participants can create demonstrable prototypes of the use of blockchain in government applications. this is a 'residential' hackathon: i...






transactions - how is bitcoin supposed to serve as currency when it is all but i


bitcoin is not like dollar, it is like gold (i.e. a store of value). bitcoin is not made for everyday transactions for a cafe or a pizza. to allow such transactions with low fees, we would have to increase block size, allowing a lot of transactions to be stored forever in the blockchain. this idea can be expressed more or less by: "we do not want every cafe or every pizza sold in the world today to be stored forever in the blockchain" the blockchain bytes are expensive (and thus the fees today), because the blockchain has to stay small. why? because if blockchain's size increases a lot faster than the average "hard disk" available to consumers, then fewer people will be able to host a node (at home or in their vps). and then only big companies will be able to host a bitcoin node, this...






blockchain - so i mined a block, but why would other nodes accept my mined block


the thing to remember here is that a bitcoin is valid if people think it is valid (i.e. is willing to accept it as payment). when you mine a block, you get coins, no matter where the block is in the blockchain (even if you fork it into a block-tree). however, these coins you just minted are only valuable to people who think they are valuable. bitcoin has a general rule that one should consider the longest blockchain (or, more precisely, the highest difficulty blockchain) to be the best.if you tried to fork the blockchain by mining your own block out of the middle of the chain, rather than the end, you would mine coins, but find it hard to actually spend them. few people (if any) would be willing to accept your coins as payment because there is a much longer blockchain out there (the main b

bitcoin is doing well, despite what dimon wants you to think


the bitcoin battle has divided wall street recently, with seemingly bright people having differing opinions.understand that when many bankers talk about bitcoin, they are generally referring to the blockchain technology that is underlying bitcoin transactions.with bitcoin, there is no centralized clearing, settlement or oversight. nor is there the ability to unmask the movers or holders of bitcoin, a code-based currency. that is all by design, and numerous people have gone to prison for drug-running and related money-laundering using the cryptocurrency.a few weeks ago, jpmorgan chief jamie dimon referred to bitcoin as a mere “fraud.”in september dimon said, “my daughter bought bitcoin, it went up, now she thinks she is a genius” (and now the dumb money is flooding in, as the crypto...
