1  Bitcoin / Development & Technical Discussion / Re: How to push your own TX with a local node. on: September 22, 2017, 10:32:19 PM
Yes. If your node is Bitcoin Core (or is based on it), you can open the debug console (Help > Debug Window > Console) and use the sendrawtransaction command.
2  Bitcoin / Development & Technical Discussion / Re: Hashing coinbase transaction to get txid on: September 22, 2017, 07:05:49 PM
Ok, great. But my regtest setup (version 14.1) gives me a similar raw coinbase transaction:
Code:
020000000001010000000000000000000000000000000000000000000000000000000000000000ffffffff050282060101ffffffff020e642500000000002321031a70a95a57f63b7d63e46803d385fd483b77f7a71a7a753ffcf7aafb67ec3edcac0000000000000000266a24aa21a9edad9d9c439414e2d257fda34cdc00667c0ecd7d78256721a4178046b49ee7382f0120000000000000000000000000000000000000000000000000000000000000000000000000
Is the implementation error in the node? Maybe working in 15.0?
Hmm. That's interesting. I can reproduce that. I will investigate and see what's up with that.

Regardless, the txid is calculated from the non-witness serialization of a transaction, so you should strip out the witness parts of this and hash the remaining. That will get you the txid.



Ok, so apparently that is actually expected behavior. From BIP 141:
Quote
and the coinbase's input's witness must consist of a single 32-byte array for the witness reserved value.
This is done to allow for future extensibility.

Also, goatpig didn't explicitly mention this but I believe this will fix the issues people were seeing when they ran Core 0.15.0.1 (i.e., the ones where goatpig told them to go back to 0.15). If you're still having issues, post your logs!
Yes, it does fix that problem, hence that one line under "== Fixed =="

You seem to be working with the following:
Code:
01000000 00010100 00000000 00000000
00000000 00000000 00000000 00000000
00000000 000000ff ffffff31 03816b07
244d696e 65642062 7920416e 74506f6f
6c6b2f45 42312f41 44362f4e 59412f33
2059c36d 7be15500 00df3200 00ffffff
ff023825 2e4d0000 00001976 a9146603
71326d3a 2e064c27 8b20107a 65dad847
e8a988ac 00000000 00000000 266a24aa
21a9edc1 1e8cdbd8 d442b27b f8f27339
5baa83b5 da4c9c3d 87fbc539 dad74248
04371001 20000000 00000000 00000000
00000000 00000000 00000000 00000000
00000000 00000000 00

Notice the extra "0120" at the end followed by an extra 36 bytes of "00"?
Also notice that you have an extra byte of "00" between the 4-byte version (the 01000000) at the beginning, and the "01" representing the number of inputs?
Then notice that you have an extra "01" byte immediately following the in-counter?
These extra bytes are resulting in an invalid hash calculation.
But I tried getting the raw transaction from electrum wallet and chainquery.com, and they all have the long tail starting with 12...
They seem to be giving you the transaction in the extended serialiation format (witness serialization when there are witnesses). This is actually incorrect and in violation of the segwit specification which states that the witness serialization for a non-witness transaction (as the coinbase transaction is) is the legacy non-extended (no witnesses) serialization format.

The extra 0001 between the version number and number of inputs is the marker and flag bytes for extended serialization. The 012000... at the end of the transaction is an incorrect and invalid witness (it means that there is a witness of 1 stack item which is 32 bytes in length and all 0's. During verification, this would be pushed to the stack, but it is incorrect to have that there at all).

Edit: That was wrong, explained in a post below.

if i have a wallet running with updated version and if it is the only wallet with updated protocol versions, how does it generate new blocks.
In whatever way the consensus rules specify that blocks should be generated.

Block generation has nothing to do with syncing.

Ah, sorry, was working from (apparently very bad) memory.

So to answer Omega's question, presumably Bech32 addresses will in fact be more difficult to create vanity addresses with?
No, it will about the same difficulty. The bitness for what people will be using as vanity addresses (P2WPKH) is the same. It's still a 160-bit hash that you need to grind in order to generate a vanity address.
8  Bitcoin / Development & Technical Discussion / Re: Lightning Network where are the transaction records stored? on: September 22, 2017, 03:16:09 AM
but how would you prove impartially your books are the correct record, when the other parties books say different?
The "books" would be the commitment transactions and their corresponding revoke_and_ack messages. The commitment transactions are signed by both parties, so you can prove that the balance for each transaction was agreed upon by both parties. The "books" cannot add transactions, only omit them. To prove that no transactions presented were omitted, you can use the per-commitment secrets and next per-commitment points in the revoke_and_ack messages to show which message corresponds to which transaction. If there is a revoke_and_ack message that has a next per-commitment point that is not used in any of the commitment transactions, then you know that at least one transaction was omitted.
9  Bitcoin / Bitcoin Discussion / Re: Bitcoin Core 0.15.0.1 Released on: September 21, 2017, 09:29:38 PM
Few post up
Oh, I missed that.

He's wrong.

I think it would, not 100% sure, there may be some mathematical subtleties I'm not aware of. In principle, it should (I think this new Bech32 format is 32-bit in length and using base 36 numbers, whereas the current address format is 33 bit and uses base 58 numbers).
No, that is completely and absolutely wrong.

First of all, current addresses are 160 bits in length (bitness is not the same as character length). Bech32 addresses are either 160 bits or 256 bits. Bech32 uses base 32 and it will actually be longer than current addresses.
10  Bitcoin / Bitcoin Discussion / Re: Bitcoin Core 0.15.0.1 Released on: September 21, 2017, 07:25:38 PM
Not sure going backwards is the way to go with bitcoin, ie the shorting of address length.. Seeing they want to use a different address for every single transaction. I mean people thought 4 billion ip (which also is 32 bit) addresses would be enough...
What are you talking about? The address length is not becoming shorter.
11  Bitcoin / Bitcoin Discussion / Re: Bitcoin Core 0.14.2 Released on: September 20, 2017, 08:39:31 PM
Bitcoin Core 0.15.0.1 has been released: https://bitcointalk.org/index.php?topic=2191238.0

For technical support for Bitcoin Core 0.14.2 (or any other version of Bitcoin Core), please make a thread in the technical support section: https://bitcointalk.org/index.php?board=4.0
12  Bitcoin / Armory / Re: Armory 0.96.2 is out (SegWit enabled) on: September 20, 2017, 08:24:45 PM
Downgrade until I put out the fix. ArmoryDB chokes on Core 0.15.0.1
By downgrade you mean downgrade Bitcoin Core, not Armory. Older versions of Armory will still have this problem. If you are not using Bitcoin Core's GUI, then the bug fix in 0.15.0.1 will not have any effect and downgrading is safe.
13  Bitcoin / Development & Technical Discussion / Re: Trying to understand P2PKH mechanism almost there but not quite there. on: September 20, 2017, 01:57:42 PM
so I should believe this guy just because has been here and knowledgeable?
he virtually basically negated to major source of bitcoin technical materials and thinks he is right, lol and I should somehow discard what is written there and follow this guy at the same time being critisized??? Haha, WHAT A BIT-COIN-CIDENCE Grin Grin   Grin

https://en.bitcoin.it/wiki/Transaction
...
A Bitcoin address is only a hash, so the sender can't provide a full public key in scriptPubKey. When redeeming coins that have been sent to a Bitcoin address, the recipient provides both the signature and the public key. The script verifies that the provided public key does hash to the hash in scriptPubKey, and then it also checks the signature against the public key...
You are horribly misunderstanding the page. The scriptPubKey is the output script of the output being spent. The scriptSig is the script of the input that spends the previous output. From the wiki:
Quote
scriptPubKey: OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG
scriptSig: <sig> <pubKey>

The only time a script like
Code:
<CAFE SIGNATURE> <CAFE PUBLIC KEY> OP_DUP OP_HASH160 <CAFE PUB KEY HASH> OP_EQUAL OP_CHECKSIG
is ever seen is during script validation where the output script is concatenated to the input script (note that this is not how script validation is done anymore by the same idea remains). This only occurs during validation and is never present in any transactions. This is also explained on https://bitcoin.org/en/developer-guide#p2pkh-script-validation, particularly in the diagrams provided there.



Side note: please stop with the aggressive behavior, insulting those who are trying to help you, and shouting (typing in all caps). Otherwise you will be temporarily banned for flaming and I will lock and delete this thread.
14  Bitcoin / Technical Support / Re: Bitcoin Core 0.15.01 on: September 19, 2017, 09:15:46 PM
What do you see about it that is not signed? Only the installers are signed and nothing changed in the release process that makes them not signed.
15  Bitcoin / Development & Technical Discussion / Re: If Core had to hard fork and use another mining algorithm, what would it be? on: September 19, 2017, 09:10:05 PM
Could have sworn the argument used to be that it wouldn't be a valid hardfork unless there was a super-majority.  Now that it might happen, a super-majority is a bad thing because it suits you? 
No, the argument is still that a valid hardfork requires a super majority of all users of Bitcoin (meaning miners, businesses, and users), in fact, it requires consensus. A super majority of miners is not enough; miners do not and cannot dictate what Bitcoin is. You need a super majority of everyone involved in Bitcoin.
16  Bitcoin / Development & Technical Discussion / Re: How do exchanges implement cold wallets and instant payments simultaneously? on: September 19, 2017, 09:07:02 PM
Most exchanges have a Hot wallet and a Cold wallet so not all coins are kept in Cold storage nor are they all kept online. The Hot wallet is online and that is the one that actually sends you the coins. IIRC you also usually deposit into the Hot wallet. Exchanges also have a Cold wallet where the bulk of their coins are stored. Coins are transferred from the Hot wallet to the Cold wallet when the Hot wallet becomes too full, and transferred from the Cold wallet to the Hot wallet when the Hot wallet becomes too empty. Such transfers are usually done on a regular basis.
17  Bitcoin / Development & Technical Discussion / Re: how bitcoin transactions work under the hood: a visual guide in json on: September 19, 2017, 09:04:33 PM
This part is completely wrong:
Quote
What is signed by the signature in the spending transaction?
- snip -
It is neither the current or previous transaction, but rather a hybrid of both.  It includes the scriptPubKey from the previous transaction, which gave them ownership in the first place and

The scriptPubKey of the previous transaction is NOT signed by the sender of the current transaction.

Only the current transaction (except the signature since that hasn’t been created yet) is signed by the sender.
No, that part is correct. The sighash perimage algorithm takes the current transaction, 0's out all scriptsigs, puts the scriptPubKey of the current input's UTXO in the scriptsig, and then appends the sighash flag to the end. That preimage is then hashed and signed. See https://bitcoin.stackexchange.com/questions/3374/how-to-redeem-a-basic-tx and https://github.com/bitcoin/bitcoin/blob/efb4383ef6c69e801ddca160a53e7fb4ee8b156a/src/script/interpreter.cpp#L1176



Some comments in addition to those that DannyHamilton has left:

Quote
remainder commission for miners
Usually that "commission" is called the transaction fee, not a commission.



scriptPubKey's can contain other scripts too, such as P2SH outputs scripts, bare multisig scripts, OP_RETURN scripts, and really any script that fits in the scriptPubKey. It is not just limited to the P2PKH script. Perhaps you should mention that.

How to Upgrade
==============

If you are running an older version, shut it down. Wait until it has completely
shut down (which might take a few minutes for older versions), then run the
installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
or `bitcoind`/`bitcoin-qt` (on Linux).

The first time you run version 0.15.0, your chainstate database will be converted to a
new format, which will take anywhere from a few minutes to half an hour,
depending on the speed of your machine.

The file format of `fee_estimates.dat` changed in version 0.15.0. Hence, a
downgrade from version 0.15.0 or upgrade to version 0.15.0 will cause all fee
estimates to be discarded.

Note that the block database format also changed in version 0.8.0 and there is no
automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading
directly from 0.7.x and earlier without redownloading the blockchain is not supported.
However, as usual, old wallet versions are still supported.

Downgrading warning
-------------------

The chainstate database for this release is not compatible with previous
releases, so if you run 0.15 and then decide to switch back to any
older version, you will need to run the old release with the `-reindex-chainstate`
option to rebuild the chainstate data structures in the old format.

If your node has pruning enabled, this will entail re-downloading and
processing the entire blockchain.

Compatibility
==============

Bitcoin Core is extensively tested on multiple operating systems using
the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported.

Bitcoin Core should also work on most other Unix-like systems but is not
frequently tested on them.

Notes for 0.15.0.1
===================

GUI startup crash issue
-------------------------

After upgrade to 0.15.0, some clients would crash at startup because a custom
fee setting was configured that no longer exists in the GUI. This is a minimal
patch to avoid this issue from occuring.

Notes for 0.15.0
================

Current SegWit support
----------------------

Version 0.15.0 supports adding a segregated witness address via the `addwitnessaddress` RPC, but
please note that this is a testing/expert RPC, which does not guarantee recovery from backup. Only use
this RPC if you know what you are doing. More complete wallet support for segregated witness is coming
in a next version.

Rescanning with encrypted wallets
---------------------------------

As in previous versions, when using an encrypted HD wallet, the keypool cannot be topped up without unlocking
the wallet. This means that currently, in order to recover from a backup of an encrypted HD wallet, the user
must unlock the wallet with a really long timeout and manually trigger a rescan, otherwise they risk missing
some keys when auto-topup cannot run. Unfortunately there is no `rescan` RPC in this version, that will be
included in a future version, so for now a rescan can be triggered using one of the `import*` commands, using
a dummy address generated by another (trusted) wallet.

Notable changes
===============

Performance Improvements
------------------------

Version 0.15 contains a number of significant performance improvements, which make
Initial Block Download, startup, transaction and block validation much faster:

- The chainstate database (which is used for tracking UTXOs) has been changed
  from a per-transaction model to a per-output model (See [PR 10195](https://github.com/bitcoin/bitcoin/pull/10195)). Advantages of this model
  are that it:
    - avoids the CPU overhead of deserializing and serializing the unused outputs;
    - has more predictable memory usage;
    - uses simpler code;
    - is adaptable to various future cache flushing strategies.

  As a result, validating the blockchain during Initial Block Download (IBD) and reindex
  is ~30-40% faster, uses 10-20% less memory, and flushes to disk far less frequently.
  The only downside is that the on-disk database is 15% larger. During the conversion from the previous format
  a few extra gigabytes may be used.
- Earlier versions experienced a spike in memory usage while flushing UTXO updates to disk.
  As a result, only half of the available memory was actually used as cache, and the other half was
  reserved to accommodate flushing. This is no longer the case (See [PR 10148](https://github.com/bitcoin/bitcoin/pull/10148)), and the entirety of
  the available cache (see `-dbcache`) is now actually used as cache. This reduces the flushing
  frequency by a factor 2 or more.
- In previous versions, signature validation for transactions has been cached when the
  transaction is accepted to the mempool. Version 0.15 extends this to cache the entire script
  validity (See [PR 10192](https://github.com/bitcoin/bitcoin/pull/10192)). This means that if a transaction in a block has already been accepted to the
  mempool, the scriptSig does not need to be re-evaluated. Empirical tests show that
  this results in new block validation being 40-50% faster.
- LevelDB has been upgraded to version 1.20 (See [PR 10544](https://github.com/bitcoin/bitcoin/pull/10544)). This version contains hardware acceleration for CRC
  on architectures supporting SSE 4.2. As a result, synchronization and block validation are now faster.
- SHA256 hashing has been optimized for architectures supporting SSE 4 (See [PR 10821](https://github.com/bitcoin/bitcoin/pull/10821)). SHA256 is around
  50% faster on supported hardware, which results in around 5% faster IBD and block
  validation. In version 0.15, SHA256 hardware optimization is disabled in release builds by
  default, but can be enabled by using `--enable-experimental-asm` when building.
- Refill of the keypool no longer flushes the wallet between each key which resulted in a ~20x speedup in creating a new wallet. Part of this speedup was used to increase the default keypool to 1000 keys to make recovery more robust. (See [PR 10831](https://github.com/bitcoin/bitcoin/pull/10831)).

Fee Estimation Improvements
---------------------------

Fee estimation has been significantly improved in version 0.15, with more accurate fee estimates used by the wallet and a wider range of options for advanced users of the `estimatesmartfee` and `estimaterawfee` RPCs (See [PR 10199](https://github.com/bitcoin/bitcoin/pull/10199)).

### Changes to internal logic and wallet behavior

- Internally, estimates are now tracked on 3 different time horizons. This allows for longer targets and means estimates adjust more quickly to changes in conditions.
- Estimates can now be *conservative* or *economical*. *Conservative* estimates use longer time horizons to produce an estimate which is less susceptible to rapid changes in fee conditions. *Economical* estimates use shorter time horizons and will be more affected by short-term changes in fee conditions. Economical estimates may be considerably lower during periods of low transaction activity (for example over weekends), but may result in transactions being unconfirmed if prevailing fees increase rapidly.
- By default, the wallet will use conservative fee estimates to increase the reliability of transactions being confirmed within the desired target. For transactions that are marked as replaceable, the wallet will use an economical estimate by default, since the fee can be 'bumped' if the fee conditions change rapidly (See [PR 10589](https://github.com/bitcoin/bitcoin/pull/10589)).
- Estimates can now be made for confirmation targets up to 1008 blocks (one week).
- More data on historical fee rates is stored, leading to more precise fee estimates.
- Transactions which leave the mempool due to eviction or other non-confirmed reasons are now taken into account by the fee estimation logic, leading to more accurate fee estimates.
- The fee estimation logic will make sure enough data has been gathered to return a meaningful estimate. If there is insufficient data, a fallback default fee is used.

### Changes to fee estimate RPCs

- The `estimatefee` RPC is now deprecated in favor of using only `estimatesmartfee` (which is the implementation used by the GUI)
- The `estimatesmartfee` RPC interface has been changed (See [PR 10707](https://github.com/bitcoin/bitcoin/pull/10707)):
    - The `nblocks` argument has been renamed to `conf_target` (to be consistent with other RPC methods).
    - An `estimate_mode` argument has been added. This argument takes one of the following strings: `CONSERVATIVE`, `ECONOMICAL` or `UNSET` (which defaults to `CONSERVATIVE`).
    - The RPC return object now contains an `errors` member, which returns errors encountered during processing.
    - If Bitcoin Core has not been running for long enough and has not seen enough blocks or transactions to produce an accurate fee estimation, an error will be returned (previously a value of -1 was used to indicate an error, which could be confused for a feerate).
- A new `estimaterawfee` RPC is added to provide raw fee data. External clients can query and use this data in their own fee estimation logic.

Multi-wallet support
--------------------

Bitcoin Core now supports loading multiple, separate wallets (See [PR 8694](https://github.com/bitcoin/bitcoin/pull/8694), [PR 10849](https://github.com/bitcoin/bitcoin/pull/10849)). The wallets are completely separated, with individual balances, keys and received transactions.

Multi-wallet is enabled by using more than one `-wallet` argument when starting Bitcoin, either on the command line or in the Bitcoin config file.

**In Bitcoin-Qt, only the first wallet will be displayed and accessible for creating and signing transactions.** GUI selectable multiple wallets will be supported in a future version. However, even in 0.15 other loaded wallets will remain synchronized to the node's current tip in the background. This can be useful if running a pruned node, since loading a wallet where the most recent sync is beyond the pruned height results in having to download and revalidate the whole blockchain. Continuing to synchronize all wallets in the background avoids this problem.

Bitcoin Core 0.15.0 contains the following changes to the RPC interface and `bitcoin-cli` for multi-wallet:

* When running Bitcoin Core with a single wallet, there are **no** changes to the RPC interface or `bitcoin-cli`. All RPC calls and `bitcoin-cli` commands continue to work as before.
* When running Bitcoin Core with multi-wallet, all *node-level* RPC methods continue to work as before. HTTP RPC requests should be send to the normal `<RPC IP address>:<RPC port>/` endpoint, and `bitcoin-cli` commands should be run as before. A *node-level* RPC method is any method which does not require access to the wallet.
* When running Bitcoin Core with multi-wallet, *wallet-level* RPC methods must specify the wallet for which they're intended in every request. HTTP RPC requests should be send to the `<RPC IP address>:<RPC port>/wallet/<wallet name>/` endpoint, for example `127.0.0.1:8332/wallet/wallet1.dat/`. `bitcoin-cli` commands should be run with a `-rpcwallet` option, for example `bitcoin-cli -rpcwallet=wallet1.dat getbalance`.
* A new *node-level* `listwallets` RPC method is added to display which wallets are currently loaded. The names returned by this method are the same as those used in the HTTP endpoint and for the `rpcwallet` argument.

Note that while multi-wallet is now fully supported, the RPC multi-wallet interface should be considered unstable for version 0.15.0, and there may backwards-incompatible changes in future versions.

Replace-by-fee control in the GUI
---------------------------------

Bitcoin Core has supported creating opt-in replace-by-fee (RBF) transactions
since version 0.12.0, and since version 0.14.0 has included a `bumpfee` RPC method to
replace unconfirmed opt-in RBF transactions with a new transaction that pays
a higher fee.

In version 0.15, creating an opt-in RBF transaction and replacing the unconfirmed
transaction with a higher-fee transaction are both supported in the GUI (See [PR 9592](https://github.com/bitcoin/bitcoin/pull/9592)).

Removal of Coin Age Priority
----------------------------

In previous versions of Bitcoin Core, a portion of each block could be reserved for transactions based on the age and value of UTXOs they spent. This concept (Coin Age Priority) is a policy choice by miners, and there are no consensus rules around the inclusion of Coin Age Priority transactions in blocks. In practice, only a few miners continue to use Coin Age Priority for transaction selection in blocks. Bitcoin Core 0.15 removes all remaining support for Coin Age Priority (See [PR 9602](https://github.com/bitcoin/bitcoin/pull/9602)). This has the following implications:

- The concept of *free transactions* has been removed. High Coin Age Priority transactions would previously be allowed to be relayed even if they didn't attach a miner fee. This is no longer possible since there is no concept of Coin Age Priority. The `-limitfreerelay` and `-relaypriority` options which controlled relay of free transactions have therefore been removed.
- The `-sendfreetransactions` option has been removed, since almost all miners do not include transactions which do not attach a transaction fee.
- The `-blockprioritysize` option has been removed.
- The `estimatepriority` and `estimatesmartpriority` RPCs have been removed.
- The `getmempoolancestors`, `getmempooldescendants`, `getmempoolentry` and `getrawmempool` RPCs no longer return `startingpriority` and `currentpriority`.
- The `prioritisetransaction` RPC no longer takes a `priority_delta` argument, which is replaced by a `dummy` argument for backwards compatibility with clients using positional arguments. The RPC is still used to change the apparent fee-rate of the transaction by using the `fee_delta` argument.
- `-minrelaytxfee` can now be set to 0. If `minrelaytxfee` is set, then fees smaller than `minrelaytxfee` (per kB) are rejected from relaying, mining and transaction creation. This defaults to 1000 satoshi/kB.
- The `-printpriority` option has been updated to only output the fee rate and hash of transactions included in a block by the mining code.

Mempool Persistence Across Restarts
-----------------------------------

Version 0.14 introduced mempool persistence across restarts (the mempool is saved to a `mempool.dat` file in the data directory prior to shutdown and restores the mempool when the node is restarted). Version 0.15 allows this feature to be switched on or off using the `-persistmempool` command-line option (See [PR 9966](https://github.com/bitcoin/bitcoin/pull/9966)). By default, the option is set to true, and the mempool is saved on shutdown and reloaded on startup. If set to false, the `mempool.dat` file will not be loaded on startup or saved on shutdown.

New RPC methods
---------------

Version 0.15 introduces several new RPC methods:

- `abortrescan` stops current wallet rescan, e.g. when triggered by an `importprivkey` call (See [PR 10208](https://github.com/bitcoin/bitcoin/pull/10208)).
- `combinerawtransaction` accepts a JSON array of raw transactions and combines them into a single raw transaction (See [PR 10571](https://github.com/bitcoin/bitcoin/pull/10571)).
- `estimaterawfee` returns raw fee data so that customized logic can be implemented to analyze the data and calculate estimates. See [Fee Estimation Improvements](#fee-estimation-improvements) for full details on changes to the fee estimation logic and interface.
- `getchaintxstats` returns statistics about the total number and rate of transactions
  in the chain (See [PR 9733](https://github.com/bitcoin/bitcoin/pull/9733)).
- `listwallets` lists wallets which are currently loaded. See the *Multi-wallet* section
  of these release notes for full details (See [Multi-wallet support](#multi-wallet-support)).
- `uptime` returns the total runtime of the `bitcoind` server since its last start (See [PR 10400](https://github.com/bitcoin/bitcoin/pull/10400)).

Low-level RPC changes
---------------------

- When using Bitcoin Core in multi-wallet mode, RPC requests for wallet methods must specify
  the wallet that they're intended for. See [Multi-wallet support](#multi-wallet-support) for full details.

- The new database model no longer stores information about transaction
  versions of unspent outputs (See [Performance improvements](#performance-improvements)). This means that:
  - The `gettxout` RPC no longer has a `version` field in the response.
  - The `gettxoutsetinfo` RPC reports `hash_serialized_2` instead of `hash_serialized`,
    which does not commit to the transaction versions of unspent outputs, but does
    commit to the height and coinbase information.
  - The `getutxos` REST path no longer reports the `txvers` field in JSON format,
    and always reports 0 for transaction versions in the binary format

- The `estimatefee` RPC is deprecated. Clients should switch to using the `estimatesmartfee` RPC, which returns better fee estimates. See [Fee Estimation Improvements](#fee-estimation-improvements) for full details on changes to the fee estimation logic and interface.

- The `gettxoutsetinfo` response now contains `disk_size` and `bogosize` instead of
  `bytes_serialized`. The first is a more accurate estimate of actual disk usage, but
  is not deterministic. The second is unrelated to disk usage, but is a
  database-independent metric of UTXO set size: it counts every UTXO entry as 50 + the
  length of its scriptPubKey (See [PR 10426](https://github.com/bitcoin/bitcoin/pull/10426)).

- `signrawtransaction` can no longer be used to combine multiple transactions into a single transaction. Instead, use the new `combinerawtransaction` RPC (See [PR 10571](https://github.com/bitcoin/bitcoin/pull/10571)).

- `fundrawtransaction` no longer accepts a `reserveChangeKey` option. This option used to allow RPC users to fund a raw transaction using an key from the keypool for the change address without removing it from the available keys in the keypool. The key could then be re-used for a `getnewaddress` call, which could potentially result in confusing or dangerous behaviour (See [PR 10784](https://github.com/bitcoin/bitcoin/pull/10784)).

- `estimatepriority` and `estimatesmartpriority` have been removed. See [Removal of Coin Age Priority](#removal-of-coin-age-priority).

- The `listunspent` RPC now takes a `query_options` argument (see [PR 8952](https://github.com/bitcoin/bitcoin/pull/8952)), which is a JSON object
  containing one or more of the following members:
  - `minimumAmount` - a number specifying the minimum value of each UTXO
  - `maximumAmount` - a number specifying the maximum value of each UTXO
  - `maximumCount` - a number specifying the minimum number of UTXOs
  - `minimumSumAmount` - a number specifying the minimum sum value of all UTXOs

- The `getmempoolancestors`, `getmempooldescendants`, `getmempoolentry` and `getrawmempool` RPCs no longer return `startingpriority` and `currentpriority`. See [Removal of Coin Age Priority](#removal-of-coin-age-priority).

- The `dumpwallet` RPC now returns the full absolute path to the dumped wallet. It
  used to return no value, even if successful (See [PR 9740](https://github.com/bitcoin/bitcoin/pull/9740)).

- In the `getpeerinfo` RPC, the return object for each peer now returns an `addrbind` member, which contains the ip address and port of the connection to the peer. This is in addition to the `addrlocal` member which contains the ip address and port of the local node as reported by the peer (See [PR 10478](https://github.com/bitcoin/bitcoin/pull/10478)).

- The `disconnectnode` RPC can now disconnect a node specified by node ID (as well as by IP address/port). To disconnect a node based on node ID, call the RPC with the new `nodeid` argument (See [PR 10143](https://github.com/bitcoin/bitcoin/pull/10143)).

- The second argument in `prioritisetransaction` has been renamed from `priority_delta` to `dummy` since Bitcoin Core no longer has a concept of coin age priority. The `dummy` argument has no functional effect, but is retained for positional argument compatibility. See [Removal of Coin Age Priority](#removal-of-coin-age-priority).

- The `resendwallettransactions` RPC throws an error if the `-walletbroadcast` option is set to false (See [PR 10995](https://github.com/bitcoin/bitcoin/pull/10995)).

- The second argument in the `submitblock` RPC argument has been renamed from `parameters` to `dummy`. This argument never had any effect, and the renaming is simply to communicate this fact to the user (See [PR 10191](https://github.com/bitcoin/bitcoin/pull/10191))
  (Clients should, however, use positional arguments for `submitblock` in order to be compatible with BIP 22.)

- The `verbose` argument of `getblock` has been renamed to `verbosity` and now takes an integer from 0 to 2. Verbose level 0 is equivalent to `verbose=false`. Verbose level 1 is equivalent to `verbose=true`. Verbose level 2 will give the full transaction details of each transaction in the output as given by `getrawtransaction`. The old behavior of using the `verbose` named argument and a boolean value is still maintained for compatibility.

- Error codes have been updated to be more accurate for the following error cases (See [PR 9853](https://github.com/bitcoin/bitcoin/pull/9853)):
  - `getblock` now returns RPC_MISC_ERROR if the block can't be found on disk (for
  example if the block has been pruned). Previously returned RPC_INTERNAL_ERROR.
  - `pruneblockchain` now returns RPC_MISC_ERROR if the blocks cannot be pruned
  because the node is not in pruned mode. Previously returned RPC_METHOD_NOT_FOUND.
  - `pruneblockchain` now returns RPC_INVALID_PARAMETER if the blocks cannot be pruned
  because the supplied timestamp is too late. Previously returned RPC_INTERNAL_ERROR.
  - `pruneblockchain` now returns RPC_MISC_ERROR if the blocks cannot be pruned
  because the blockchain is too short. Previously returned RPC_INTERNAL_ERROR.
  - `setban` now returns RPC_CLIENT_INVALID_IP_OR_SUBNET if the supplied IP address
  or subnet is invalid. Previously returned RPC_CLIENT_NODE_ALREADY_ADDED.
  - `setban` now returns RPC_CLIENT_INVALID_IP_OR_SUBNET if the user tries to unban
  a node that has not previously been banned. Previously returned RPC_MISC_ERROR.
  - `removeprunedfunds` now returns RPC_WALLET_ERROR if `bitcoind` is unable to remove
  the transaction. Previously returned RPC_INTERNAL_ERROR.
  - `removeprunedfunds` now returns RPC_INVALID_PARAMETER if the transaction does not
  exist in the wallet. Previously returned RPC_INTERNAL_ERROR.
  - `fundrawtransaction` now returns RPC_INVALID_ADDRESS_OR_KEY if an invalid change
  address is provided. Previously returned RPC_INVALID_PARAMETER.
  - `fundrawtransaction` now returns RPC_WALLET_ERROR if `bitcoind` is unable to create
  the transaction. The error message provides further details. Previously returned
  RPC_INTERNAL_ERROR.
  - `bumpfee` now returns RPC_INVALID_PARAMETER if the provided transaction has
  descendants in the wallet. Previously returned RPC_MISC_ERROR.
  - `bumpfee` now returns RPC_INVALID_PARAMETER if the provided transaction has
  descendants in the mempool. Previously returned RPC_MISC_ERROR.
  - `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction has
  has been mined or conflicts with a mined transaction. Previously returned
  RPC_INVALID_ADDRESS_OR_KEY.
  - `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction is not
  BIP 125 replaceable. Previously returned RPC_INVALID_ADDRESS_OR_KEY.
  - `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction has already
  been bumped by a different transaction. Previously returned RPC_INVALID_REQUEST.
  - `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction contains
  inputs which don't belong to this wallet. Previously returned RPC_INVALID_ADDRESS_OR_KEY.
  - `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction has multiple change
  outputs. Previously returned RPC_MISC_ERROR.
  - `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction has no change
  output. Previously returned RPC_MISC_ERROR.
  - `bumpfee` now returns RPC_WALLET_ERROR if the fee is too high. Previously returned
  RPC_MISC_ERROR.
  - `bumpfee` now returns RPC_WALLET_ERROR if the fee is too low. Previously returned
  RPC_MISC_ERROR.
  - `bumpfee` now returns RPC_WALLET_ERROR if the change output is too small to bump the
  fee. Previously returned RPC_MISC_ERROR.

20  Bitcoin / Development & Technical Discussion / Re: A replacement Alert System should be considered to promote updates as necessary on: September 19, 2017, 02:03:04 PM
I don't understand what you mean when you refer to a singular "trusted authority".
The trusted authority is the group "Bitcoin Core developers" in general. It doesn't matter that there are multiple people in that group who would have to sign off on an alert, they are a trusted authority as they are part of the group "Bitcoin Core developers". Because those developers are part of the same group, they, as an entity, may decide to publish an alert for something which users may not want. Users have to trust that the group as a whole does not partake in any malicious behavior.
