The hashrate can be calculated from the expected rate of finding a block (144 a day), the actual rate of finding a block and the current difficulty. So let's calculate the average hash_rate for a single day: expected_blocks = 144 difficulty = 11187257.461361 # this is on May 22nd 2013 blocks_found = 155 # Also May 22nd 2013 hash_rate = (blocks_found/...

This chart can answer that question for any period you choose: https://tradeblock.com/bitcoin/historical/1w-f-txval_per_avg-11101 Measured in BTC, the average transaction value was naturally the highest in the early days of bitcoin when its value was much less in fiat terms

The network hash rate can be statistically inferred from the difficulty and the rate at which blocks are found. It's just a more complex version of the fact that if you know that someone is flipping coins and heads comes up 800 times an hour, they're flipping about 1,600 coins an hour.

I've not touched a large part of my online wallet (two weeks), nor the paper wallets under my sink (two years), but they are by no means disappeared, idle or lost. There's really no way of telling, no matter how much thought is put into it. Some coins can be called lost, that is they don't have any associated private keys known, but there's no way of ...

The ledger chain stores all transactions. So yes, you can rebuild the transaction history. But the validators don't need to store or serve the whole chain to operate. A new validator only needs the last closed ledger to validate new transactions. This is different from bitcoin, where nodes need the last output of the relevant public key to validate a new ...

not sure what you mean by logarithmic graph. The time in a logarithmic scale, or the value? On both, there is a "log" button below the graph. And you can export as CSV or JSON: https://blockchain.info/de/charts/market-price?timespan=all or alternativly: https://coinmarketcap.com/currencies/bitcoin/

There has been a rally in price of 10% or more since May, and there is constant supply of new bitcoins entering the market, so some of the cash from the order book has since moved into bitcoins. But no doubt, a thicker order book (reflecting lots of buying interest) lessens the risk of a selloff. When Mt. Gox's BTC/USD represented 80% or more of the ...

There does not seem to be a chart like that for this website. Not every exchange provides a live chart on its own, and asides the two websites you mentioned, there aren't any other that would provide access to a more "live" feed.

It is impossible to tell lost coins from stored coins, because there is not way to tell if anyone has the private key associated with a foreign address. The only coins that can realiably be declared lost are those that have been assigned to invalid recipient addresses.

The blue bars indicate the transaction volume in that period, this is how many bitcoins have been traded. Use the blue numbers at the left axis to see how many bitcoins were traded. The yellow line is the average weighted price in that period. Use the yellow numbers on the right to see what the price is. The green and red parts show the fluctuations (high &...

As mentioned, raw transactions are incredibly easy to screw up since you must explicitly pay yourself if you want change. Here's a few scenarios besides unbalanced outputs which will produce huge transaction (Tx) fees: forgetting to pay change forgetting to convert to Satoshis in your code misplacing the decimal (perhaps due to rounding errors) swapping ...

In my opinion, you should not use Mt. Gox as an indication of the price of Bitcoin. The price on Mt. Gox is significantly higher than the other exchanges, because sellers must be compensated for the difficulty of getting their money off the site. Instead, you might use BTC-e for pricing info. Here is the chart you ask for: http://bitcoincharts.com/charts/...
