I recently experienced a power failure while performing the Initial Block Download onto a Samsung T7 solid state drive, which was partitioned for ext4 and mounted with the default data=ordered journaling option. My node was running with the following parameters: -txindex=1 -blockfilterindex=1 peerblockfilters=1.

The node started back up without any issues. However, I am concerned about the possibility of data corruption (blocks, indexes, etc.) due to the power failure. To be on the safe side, I've decided to restart the node with -checkblocks=0 -checklevel=3 options to verify the integrity of the stored data.

Is this enough to ensure that no data has been corrupted due to the power failure? Or should I consider taking additional steps to verify the integrity of my node data?

Thank you in advance for your help!

I'm checking out OKEx and Kraken. Could anyone comment on the relative strengths of their futures trading platforms?

Looks like we'll be getting an increase of about 0.88%. Miner capitulation has already happened. This is it!

# Release 3.2.0 - Satoshi's Vision (June 30, 2018)

 * If present, libsecp256k1 is used to speed up elliptic curve
   operations. The library is bundled in the Windows, MacOS, and
   Android binaries. On Linux, it needs to be installed separately.
 * Two-factor authentication is available on Android. Note that this
   will only provide additional security if one time passwords are
   generated on a separate device.
 * Semi-automated crash reporting is implemented for Android.
 * Transactions that are dropped from the mempool are kept in the
   wallet as 'local', and can be rebroadcast. Previously these
   transactions were deleted from the wallet.
 * The scriptSig and witness part of transaction inputs are no longer
   parsed, unless actually needed. The wallet will no longer display
   'from' addresses corresponding to transaction inputs, except for
   its own inputs.
 * The partial transaction format has been incompatibly changed. This
   was needed as for partial transactions the scriptSig/witness has to
   be parsed, but for signed transactions we did not want to do the
   parsing.  Users should make sure that all instances of Electrum
   they use to co-sign or offline sign, are updated together.
 * Signing of partial transactions created with online imported
   addresses wallets now supports significantly more
   setups. Previously only online p2pkh address + offline WIF was
   supported.  Now the following setups are all supported:
   - online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline WIF,
   - online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline seed/xprv,
   - online {p2sh, p2wsh-p2sh, p2wsh}-multisig address + offline seeds/xprvs
     (potentially distributed among several different machines)
   Note that for the online address + offline HD secret case, you need
   the offline wallet to recognize the address (i.e. within gap
   limit).  Having an xpub on the online machine is still the
   recommended setup, as this allows the online machine to generate
   new addresses on demand.
 * Segwit multisig for bip39 and hardware wallets is now enabled.
   (both p2wsh-p2sh and native p2wsh)
 * Ledger: offline signing for segwit inputs (#3302) This has already
   worked for Trezor and Digital Bitbox. Offline segwit signing can be
   combined with online imported addresses wallets.
 * Added Revealer plugin. ( https://revealer.cc ) Revealer is a seed
   phrase back-up solution. It allows you to create a cold, analog,
   multi-factor backup of your wallet seeds, or of any arbitrary
   secret. The Revealer utilizes a transparent plastic visual one time
   pad.
 * Fractional fee rates: the Qt GUI now displays fee rates with 0.1
   sat/byte precision, and also allows this same resolution in the
   Send tab.
 * Hardware wallets: a "show address" button is now displayed in the
   Receive tab of the Qt GUI. (#4316)
 * Trezor One: implemented advanced/matrix recovery (#4329)
 * Qt/Kivy: added "sat" as optional base unit.
 * Kivy GUI: significant performance improvements when displaying
   history and address list of large wallets; and transaction dialog
   of large transactions.
 * Windows: use dnspython to resolve dns instead of socket.getaddrinfo
   (#4422)
 * Importing minikeys: use uncompressed pubkey instead of compressed
   (#4384)
 * SPV proofs: check inner nodes not to be valid transactions (#4436)
 * Qt GUI: there is now an optional "dark" theme (#4461)
 * Several other minor bugfixes and usability improvements.

At that time the inflation rate will drop to 1.79%. Just a reminder everyone.

I think the US doesn't charge nonresident aliens if using a US exchange. Trying to be sure though. Hard to find good attorneys. Anyone here have experience with that?

Sorta strange we are at an ATH but at the moment it seems like diff will stay about even or drop very slightly. Thoughts as to why?

Already two weeks earlier than it was scheduled. Not many coins left. Don't let the wealth effect take your coins when you get rich.

I notice Gmail warns emails to bitcointalk.org aren't encrypted in transit. Perhaps good to enable?

I love listening to this during rallies.

All hail the dragon.

Now past the high of the week of Aug 24 2014.

If this CW scam, blocksize debate, etc. and the ensuing media attention won't make Satoshi sign something saying he is not CW, then nothing can do so. He will make a move if and when he decides (if he is still alive). So although this is just a stupid sideshow it does provide us with additional information which can be useful to pricing our favorite asset. Satoshi is not going to raise his head until he is good and ready, and that is likely some time (in terms of price) from now.

I can't believe it! Here's a volatility update as of April 17, 2016:

60-day volatility has fallen to the 2nd lowest on record! 1.315%

And 30-day is now the lowest on record! 0.723%

What comes next?

Didn't even think I could get money for my dog until another poster here pointed that out. Thanks! Now I'm making my last post before I sell my laptop. Gotta switch to a paper wallet. This time I'm going all in! Fortunately public nudity is not illegal around these parts. See you guys after the halving!

Turning that topic on its head!

In reality I hold bitcoin, not dollars.

I think the answer is no. The age of the billionaire will not be replaced by the age of the trillionaire but by the thousandaire.

30-day volatility is below 1% as of today for the first time since January 2013. The price has never been this high and this stable. Sort of exciting!

Some numbers:
60-day vol: 1.50753099% 36th least vol. on record
30-day vol: 0.97875074% 15th least vol. on record

Source: https://btcvol.info/ (standard deviation of daily returns for preceding 30- & 60-day windows)

Lowest on record are 0.86% and 1.41% just after the last halving. Will volatility drop to new lows?

Edit: 0.79116124% and 1.3148784% are actually the lowest on record.

Market cap in blue, bitcoin price in red, starting on the same zero point at the left and diverging as inflation takes away from the price of each coin.

Peak market cap is 2.06x current market cap compared to peak btc price which is 2.59x, a 26% difference.

The slope of the trend lines are interesting as well.

peak 13900051500, 1151.0
current 6751214190, 448.2

Whoops, too early.
