See the -asmap configuration option in New Settings, above. In the Peers window, the details for a peer now displays a Mapped AS field to indicate the mapped Autonomous System used for diversifying peer selection.The “Start Bitcoin Core on system login” option has been removed on macOS.The -whitelistforcerelay configuration parameter has been removed after it was discovered that it was rendered ineffective in version 0.13 and hasn’t actually been supported for almost four years.The -walletnotify configuration parameter will now replace any %w in its argument with the name of the wallet generating the notification.The -debug=db option has been deprecated and will be removed in the next major release. The -debug=db logging category has been renamed to -debug=walletdb to distinguish it from coindb.The file must now be specified with -loadblock=. Importing blocks upon startup via the bootstrap.dat file no longer occurs by default.All custom settings configured when Bitcoin Core starts are now written to the debug.log file to assist troubleshooting.This option is experimental and subject to removal or breaking changes in future releases, so the legacy /16 prefix mapping of IP addresses remains the default. See issue #16599, PR #16702, and the bitcoind help for more information. A new -asmap configuration option has been added to diversify the node’s network connections by mapping IP addresses Autonomous System Numbers (ASNs) and then limiting the number of connections made to any single ASN.New rpcwhitelist and rpcwhitelistdefault configuration parameters allow giving certain RPC users permissions to only some RPC calls.This implies that autotools and other required packages are installed on the user’s system. autogen.sh script from the root of the unpacked archive. Therefore, to build from such source, a user should run the.
Bitcoin core code#
The source code archives that are provided with gitian builds no longer contain any autotools artifacts.This retains compatibility with RHEL 7, CentOS 7, Debian 8 and Ubuntu 14.04 LTS. glibc 2.17 or greater is now required to run the release binaries.The -enable-bip70 option remains, but it will throw an error during configure. BIP70 support has been fully removed from Bitcoin Core.OpenSSL is no longer used by Bitcoin Core.The createmultisig and addmultisigaddress RPCs now return an output script descriptor for the newly created address.See the -asmap configuration option described below in New Settings. The getpeerinfo RPC now includes a mapped_as field to indicate the mapped Autonomous System used for diversifying peer selection.The bumpfee RPC will return a PSBT when used with wallets that have private keys disabled.The bumpfee RPC’s parameter totalFee, which was deprecated in 0.19, has been removed.This can be disabled by setting the bip32derivs parameter to false. The walletprocesspsbt and walletcreatefundedpsbt RPCs now include BIP32 derivation paths by default for public keys if we know them.The RPCs which accept descriptors now accept the new sortedmulti(.) descriptor type which supports multisig scripts where the public keys are sorted lexicographically in the resulting script.The reason for rejection is still reported. Log messages that previously reported the reject code when a transaction was not accepted to the mempool now no longer report the reject code.They still return the verbal reject reason. testmempoolaccept and sendrawtransaction no longer return the P2P reject code when a transaction is not accepted to the mempool.The removal of BIP61 reject message support also has the following minor RPC and logging implications: Nodes on the network can not generally be trusted to send valid messages (including reject messages), so this should only ever be used when connected to a trusted node. (#17004) This feature has been disabled by default since Bitcoin Core version 0.18.0.
The -enablebip61 command line option to enable BIP61 has been removed. P2P and network changes - Removal of BIP61 reject network messages from Bitcoin Core De releasenotes zien er als volgt uit: Notable changes Het Core-ontwikkelteam heeft Bitcoin Core 0.20.0 uitgebracht. En om een node te draaien kun je gebruikmaken van Bitcoin Core, dat in de volksmond ook wel Satoshi-client wordt genoemd. Het Bitcoin-netwerk bestaat uit verschillende nodes. De grondlegger van de techniek en tegelijk bekendste is Bitcoin. Blockchains en cryptovaluta zijn inmiddels niet meer weg te denken uit het nieuws in welke vorm dan ook.
