Bitcoin qt data directory models

4 stars based on 35 reviews

This is a new major version release, including new features, various bugfixes and performance improvements, as well as updated translations. If you are running an older version, shut it down. The first time you run version 0. Note that the block database format also changed in version 0. Upgrading directly from 0. However, bitcoin qt data directory models usual, old wallet versions are still supported. Wallets created in 0. Existing wallets that were created with older versions are not affected by this.

Bitcoin Core is extensively tested on multiple operating systems using the Linux kernel, bitcoin qt data directory models Windows XP is not supported. Bitcoin Core should also work on most other Unix-like systems but is not frequently tested on them. A new -addresstype argument has been added, which supports legacyp2sh-segwit defaultand bech32 addresses. It controls what kind of addresses are produced by getnewaddressgetaccountaddressand createmultisigaddress.

A -changetype argument has also been added, with the same options, and by default equal bitcoin qt data directory models -addresstypeto control which kind of change is used. Note that some RPCs do not yet support segwit addresses. Support for segwit in those RPCs will continue to be added in future versions. This is done to ensure the change output is as indistinguishable from the other outputs as possible in either case.

This includes the ability to send to BIP addresses including non-v0 onesand generating these addresses including as default new addresses, see above.

A checkbox has been added to the GUI to select whether a Bech32 address or P2SH-wrapped address should be generated when using segwit addresses. Due to a backward-incompatible change in the wallet database, wallets created with version 0.

Note that this only applies to new wallets; wallets made with previous versions will not be upgraded to be HD. There is a checkbox to mark the transaction as final.

The RPC default remains unchanged: Bitcoin Core now has more flexibility in where the wallets bitcoin qt data directory models can be located. Previously wallet database files were stored at the top level of the bitcoin data directory.

The behavior is now:. Care should be taken when choosing the wallets directory location, as if it becomes unavailable during operation, funds may be lost. No effort bitcoin qt data directory models be made to support older versions of GCC. See discussion in issue for more information. The minimum version for the Clang compiler is still 3. This would bitcoin qt data directory models pruned nodes to serve the most recent blocks.

However, the current change does not yet include support for connecting to these pruned peers. In previous versions they were enabled using the --enable-experimental-asm flag when building, but are now the default and no longer deemed experimental. A new RPC rescanblockchain has been added to manually invoke a blockchain rescan. The RPC supports start and end-height arguments for the rescan, and can be used bitcoin qt data directory models a multiwallet environment to rescan the blockchain at runtime.

Safe mode is a feature that disables a subset of RPC calls - mostly related to the wallet and sending - automatically in case certain problem conditions with the network are detected. However, developers have come to regard these checks as not reliable enough to act on automatically.

Even with safe mode disabled, they will still cause warnings in the warnings field of the getneworkinfo RPC and launch the -alertnotify command. The value for embedded includes much of the information validateaddress would report if invoked directly on the embedded address. This is a replacement for the existing addresses field which reports the same information but encoded as P2PKH bitcoin qt data directory modelsrepresented in a more useful and less confusing way.

The addresses field remains present for non-segwit addresses for backward compatibility. In particular, this means that invoking validateaddress on bitcoin qt data directory models output of getnewaddress will always report the pubkeyeven when the address type is P2SH-P2WPKH.

As well as everyone that helped translating on Transifex. Bitcoin Core version 0. Please report bugs using the issue tracker at GitHub: Downgrading warning Wallets created in 0. Compatibility Bitcoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS This means that downgrading after creating a segwit address will work, as long as the wallet file is up to date.

All segwit keys in the wallet get an implicit redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software. All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a segwit address will work Note that some RPCs do not yet support segwit addresses.

HD-wallets by default Due to a backward-incompatible change in the wallet bitcoin qt data directory models, wallets created with version 0.

Wallets directory configuration -walletdir Bitcoin Core now has more flexibility in where the wallets directory can be located. The behavior is now: For existing nodes where the data directory already existswallets will be stored in the data directory root by default. Minimum GCC bumped to 4. The option to reuse a previous address has now been removed. Support for searching by TXID has been added, rather than just address and label.

A toggle for unblinding the password fields on the password dialog has been added. Validateaddress improvements The validateaddress RPC output has been extended with a few new fields, and support for segwit addresses both P2SH and Bech Low-level bitcoin qt data directory models The deprecated RPC getinfo was removed.

It is recommended that the more specific RPCs are used: The wallet RPC addwitnessaddress was deprecated and will be removed in bitcoin qt data directory models 0.

The RPC getblockchaininfo now includes an errors field. A new blockhash parameter has been added to the getrawtransaction RPC which allows for a raw transaction to be fetched from a specific block if known, even without -txindex enabled. The decoderawtransaction and fundrawtransaction RPCs now bitcoin qt data directory models optional iswitness parameters to override the heuristic witness checks if necessary.

Using addresses with the createmultisig RPC is now deprecated, and will be removed in a later version. Public keys should be used instead. The logging RPC has now been made public rather than hidden. An initialblockdownload boolean has been added to the getblockchaininfo RPC to indicate whether the node is currently in IBD or not. The -usehd option has been removed. Segwit is now always active in regtest mode by default. Failure to do this will result in a CheckBlockIndex assertion failure that will look like: Open files read only if requested Elbandi 46d1ebf Document partial validation in ConnectBlock sdaftuar c Make all script validation flags backward compatible sipa f Add a CChainState class to validation.

Bitcoin Core runs as a full network node and maintains a local copy of the block chain. This data independence improves wallet privacy and security. With local access to the complete set of headers and transactions, Bitcoin Core can use full verification to tell when peers lie about payments.

However, dealing with the block chain comes at a price. An ever-growing data set causes smaller hard drives to fill up quickly. This article describes two approaches that can be used with either a new or existing Bitcoin Core 0. To protect yourself from loss of funds, make a backup of your wallet now. After the backup has been saved, exit Bitcoin Core. The first step is finding the default data directory.

Mac, Windows, and Linux version of Bitcoin Core each store data in a different location. The procedure described here will use a graphical file browser to find it. On Windows 7, begin by clicking on the Windows menu. Then click your username from the right-hand menu. Windows Explorer should show a folder containing other folders such as Contacts and Desktop. Another folder, AppData is hidden by default.

Windows Explorer should now display an AppData folder. Then enter the Roaming folder, where the Bitcoin folder is contained. Double click on the Application Support folder. On Ubuntu, open a file browser by clicking on the folder icon in the launcher.

Having found the default data directory, we can now copy it. Be sure that Bitcoin Core has been shut down and is no longer running. The software occasionally takes a minute or two to completely exit. Begin by renaming the Bitcoin Core data directory. Use the name bitcoin-backup.

This allows recovery of the original data directory in case something goes wrong. To recover the original, reinstate the original name of the bitcoin-backup folder either Bitcoin or. Next copy the renamed bitcoin data directory to a destination of your choice. This can be the same hard drive, an external hard drive, or a removable medium such as USB drive or SD card. Copying data may require only a few minutes or a couple of hours, depending on how up-to-date your copy of the block chain is and the speed of your hardware.

You can now rename the copied folder. For example, it might be convenient to use the name Bitcoin. With no default data directory, Bitcoin Core assumes that this is its first session.

Launching Bitcoin Core should yield a welcome screen. This screen gives you to option to store data in the default location or a custom location. Select the second option. Bitcoin Core should continue starting up. When the process completes, the software should work exactly as it did before. When ready to proceed to the next step, close the application.

At this point your system contains two more or less identical copies of the data directory. Assuming there were no issues with the move, the original can now be deleted. Browse to the location of the bitcoin-backup directory and delete it. Users of Armory on Mac face a tricky problem when trying to move the Bitcoin Core data directory. Armory only recognizes the default data directory on OS X. Moving it means that Armory will no longer function. Fortunately, the solution is relatively simple.

Create a symbolic link from the new data directory to the old default directory. Creating this link allows the new data directory to be used as if it still resided at the old location. Begin by launching the Terminal application. Instead of pulling the data directory out from under Bitcoin Core and then supplying a new path after startup, the data directory can be passed as the command line parameter datadir. This approach keeps the existing default data directory intact.

It also allows multiple data directories to be used side-by-side. Windows users can create a shortcut that uses the command line option datadir.

Doing so directs Bitcoin Core to use, not the default data directory, but the one given as a parameter. Browse to the location of the Bitcoin Core executable C: Next, add the command line option datadir , using the path to your data directory. Double clicking the newly-created shortcut will direct Bitcoin Core to use the new data directory.

This places a shortcut on the desktop. Double clicking the resulting shortcut starts Bitcoin Core with the custom data directory. Although a similar shortcut-based approach will work on OS X, creating a clickable icon is much more difficult. Copy the Data Directory Having found the default data directory, we can now copy it.

Delete the Original Data Directory At this point your system contains two more or less identical copies of the data directory. Command Line Parameter Instead of pulling the data directory out from under Bitcoin Core and then supplying a new path after startup, the data directory can be passed as the command line parameter datadir.
