Anyone know how to specify the block filter index for the new getindexinfo rpc? bash-5.0# bitcoin-cli getindexinfo
{
"txindex": {
"synced": true,
"best_block_height": 771336
},
"coinstatsindex": {
"synced": true,
"best_block_height": 771336
},
"basic block filter index": {
"synced": true,
"best_block_height": 771336
}
}
bash-5.0# bitcoin-cli getindexinfo blockfilterindex

I have my node (Satoshi 0.11.0) set with txindex=1 Given a random set I can pull up any transaction by TXID using getrawtransaction, however when I try to pull up the transaction in the Genesis block I get: bitcoin-cli getrawtransaction 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b No information available about transaction (code -5) I'm wondering if there is a way to get the transaction on my node? |

Running "bitcoin-cli help encryptwallet" returns the help page as expected if the wallet is not encrypted, however if the wallet has been encrypted "help encryptwallet" returns "unknown command". It does not feel like this should be expected behavior, but maybe it is intentional? Command:bitcoin-cli help encryptwallet help: unknown command: encryptwallet
encryptwallet "passphrase"
Encrypts the wallet with 'passphrase'. This is for first time encryption.
After this, any calls that interact with private keys such as sending or signing
will require the passphrase to be set prior the making these calls.
Use the walletpassphrase call for this, and then walletlock call.
If the wallet is already encrypted, use the walletpassphrasechange call.
Note that this will shutdown the server.
Arguments:
1. "passphrase" (string) The pass phrase to encrypt the wallet with. It must be at least 1 character, but should be long.
Examples:
Encrypt you wallet
> bitcoin-cli encryptwallet "my pass phrase"
Now set the passphrase to use the wallet, such as for signing or sending bitcoin
> bitcoin-cli walletpassphrase "my pass phrase"
Now we can so something like sign
> bitcoin-cli signmessage "bitcoinaddress" "test message"
Now lock the wallet again by removing the passphrase
> bitcoin-cli walletlock
As a json rpc call
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "encryptwallet", "params": ["my pass phrase"] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
Edit: Satoshi Client 0.11.0 |

Originally planned on holding off on releasing this until all the API commands were integrated, but with the recent large increase in transaction volume, an Alpha release with what is ready seemed appropriate. In particular estimatefee and getmempoolinfo are now publicly available through your browser, along with 25 other API commands. When all the Bitcoin Core 0.10.2 commands are complete the whole thing will be released on GitHub as open source. So without further ado, http://ChainQuery.com/bitcoin-apiCurrently supported commands: Built for the average Joe to explore Bitcoin's core API and to serve as the foundation for PHP web applications to easily communicate with bitcoin core. I hope you like it so far, any questions or feedback are welcome and appreciated. |

1. Sheets 2. Donations to non-profits 3. Headphones 4. Cases and holders 5. Area rugs 6. Cables and tools 7. Mattresses 8. Coffee tables 9. A/V cables 10. Fashion sunglasses Pretty cool that donations is #2. Sheets at #1 is surprising, maybe people madly stuffing paper wallets into their mattresses created a need?  |

Marc Andressen took to Twitter today to share his thoughts on the state of Bitcoin in 26 tweets. Here is what he had to say... Some thoughts on the state of Bitcoin, cryptocurrencies, and distributed transaction and trust networks at start of 2015! A year ago I articulated my views on Bitcoin in the New York Times, and I wouldn’t change a word today: http://dealbook.nytimes.com/2014/01/21/why-bitcoin-matters/Over the last several months of 2014, there were three Bitcoin counter-narratives that I will describe and analyze: First, what I call the “dumb” critique: “Bitcoin BTC currency price dropped to below $300, proving Bitcoin is a stupid idea.” Same class of critics slamming BTC for price falling in 2014 were slamming BTC for price rising in 2013. Only consistency is the slamming. Further, the critique that BTC is bad because it was down in 2014 changes completely if one uses a 2-year window instead of 1-year window. BTC was below $14 in Jan 2013. If 1-year performance has been disappointing, 2-year performance has been spectacular. As a general rule, arguments that rely on cherry-picking specific date windows are not very good arguments. The second critique I call “smarter”: “BTC is too volatile — it goes up and down too much and so cannot be used as a store of value.” This is largely correct at the moment, and yet misses most of the point of Bitcoin as a distributed transaction and trust network. Bitcoin was specifically designed to use speculation early on to overcome the normal chicken/egg boostrapping problem for new networks. Attacking Bitcoin for having speculative levels of volatility is missing the point of how the system was designed for this point in time. Now, yes, in the long run, BTC does need to stabilize — which I think will happen with a combo of scale + use of derivatives (hedging). In the short run, Bitcoin is still highly useful as a transaction and trust network in many uses cases even with high volatility. For example, payment applications of BItcoin don’t require users/merchants to hold BTC for any period of time. All benefits still gained. Further, all other uses cases of Bitcoin and the blockchain are unhampered by volatility of BTC. The system continues working just fine. Net net, the network boostrapping process is happening pretty much exactly as Satoshi designed and anticipated. It’s a thing of beauty. The third critique I call the “innocent” one — “Are there enough sufficiently compelling uses cases for Bitcoin to succeed at scale?” I previously identified many uses cases here http://dealbook.nytimes.com/2014/01/21/why-bitcoin-matters/ … ranging from ecommerce to remittance to micropayments to anti-spam. Two particular areas of focus today are A use outside the US where currencies + banks are often awful, and B machine-to-machine payments. At our venture firm, we continue to see an escalating stream of fascinating new Bitcoin uses cases and applications from entrepeneurs. In addition, there are entirely new vistas of technological creativity opening up, such as sidechains http://www.blockstream.com/sidechains.pdf . The price of BTC has very little to do with the level of creativity of thinking that’s going into new Bitcoin apps, or their usefulness. By loose analogy, the price of domain names didn’t determine the usefulness of the Internet. This is a broad-based technology phenomenon. What to watch in 2015: New apps, new use cases, international adoption, consumer education, technological innovation & spinoff ideas! Final thought: The entire Bitcoin system is 6 years old. TCP/IP was 6 years old in 1981. Big things take time. Onward! Source and links to the tweets: https://medium.com/@CoinCadence/marc-andreessens-26-twitter-posts-6d8189f74499 |

Man, is it just me or has this whole forum been taken over by trolls shouting "the sky is falling" in the last few days?
What gives folks?

My original post here: http://www.reddit.com/r/Bitcoin/comments/2mkmoq/til_where_the_bitcoins_at_mysteries_of_the/TIL: Where the bitcoins at… Mysteries of the BlockchainI love both the transparency and the pseudonymity that bitcoin provides, so I thought I’d take a gander at the blockchain and see what there was to see. There are a couple sites that list the “100 richest addresses”, but I’m a curious guy and a bit of a data junky and wanted to see what else the blockchain could reveal. A little PHP, a current bitcoin node with the full transaction index, a MySQL database, 5 days(!) of processing time on a server and I now have every single unspent output in the blockchain in my DB. An unspent output is essentially a transaction to a public addresses that not been spent, i.e. has a balance. I started with the genesis block (#1) and followed the coins all the way up to today. The data is not perfect, there were some transactions I simply could not parse that were either null or non-standard. Here is some of what I learned as of block 330,433 (Monday November 17th, 2014): There are currently 14,104,525 unspent outputs in 3,609,649 unique address.Zero value transactions:There are 3,393 unspent outputs that contain 0.00000000, this is curious because obviously you cannot spend a 0 balance. In looking at the transactions many of the early ones include a high fee, and then sent 0 BTC to many addresses, talk about blockchain spam and bloat… The first occurrence was in block 82,627 and the latest was in block 329,151. Here is an example of an early one that simply looks like some kind of spam attack on the network, these stopped occurring so I assume someone fixed it: https://blockchain.info/tx/9173744691ac25f3cd94f35d4fc0e0a2b9d1ab17b4fe562acc07660552f95518Here is one of the more recent ones, it only sends 0 BTC to a single address, but its still an unspent output that is worthless: https://blockchain.info/tx/83277716e29cfaef9525fdd732fa39e008afd7a50302218eaf5073e87a082b24Perhaps someone with more knowledge then I can shed some light on these… 1 Satoshi Multisig:There are 16,848 multisig addresses with a 0.00000001 balance. Why? who knows… example: https://blockchain.info/tx/045727591618d2154239956332f307c754a52c0e7896856a05848ec7065db1c3Total of 1 Satoshi addresses:There are 732,959 addresses with a 1 Satoshi balance totaling 0.00732959 BTC Untouched early mining income:In the early days of mining using the bitcoin client each 50 BTC mining reward (when 0 transaction fees were included) would go to a unique address, there are still 39,228 transactions with an unspent 50 BTC balance, thats 1,961,400 Bitcoin. Some of these are not newly generated coins, simply a transaction containing 50 BTC, however the vast majority are old mining income. Many of these probably belong to Satoshi… example: https://blockchain.info/tx/b0a478fc79ecca1173cefe5975dd4a9874593cceb44b66ea4ea14eb40d587a14Broken addresses:There are 326 addresses with a balance where the address is “non standard”, a non standard address is one that cannot be decoded by the bitcoin core, and most likely can never be spent again. Total non standard unspent outputs = 2,614.256208 BTC example: https://blockchain.info/tx/ddddf9f04b4c1d4e1185cacf5cf302f3d11dee5d74f71721d741fbb507062e9eMany 1’s:There are 531 transactions going to a very unique address: 1111111111111111111114oLvT2 (many of them with advertisement like notes) https://blockchain.info/address/1111111111111111111114oLvT2While this is a valid address it is very likely that no individual has the private key for it, and the 2.98804915 BTC in it can never be spent A selection of other unique addresses that are valid and contain a balance, but most likely no one has the key for:- 1BitcoinKicksAss1111111111114BbAUx

There is a lot more to be discovered, but that’s it for now. If there is anything you would like to know about unspent transactions just ask, if your question can be expressed as SQL I’ll do my best to get you an answer… I’m considering keeping the database updated in real time and publishing some or all of this on my website, http://www.CoinCadence.com would that interest you? |

Claiming to be China’s largest holder of bitcoin, angel investor Li Xiao Lai has funded a new Beijing-based currency mining operation, Sfards Technology. The company is the result of a merger between Gridseed and WiiBox. Additional funding was provided by venture capital firm Matrix Partners China. The seed capital for the new endeavor was not disclosed in a press release.
Lai will lead the management team for the new operation which plans to launch “next-stage” ASIC technology, promising more power and efficiency.
“We are also expanding the capabilities of the WiiBox: an open-source mining hardware control system,” the company said in the release. “The platform will now also include an innovative hash rate rental feature, granting users the ability to seamlessly rent their equipment and use bought hashing power to mine a multitude of coins with complete autonomy.”
Sfards also states that it intends to offer cloud mining services in the future.
