Core/Blockstream are now in the Kübler-Ross "Bargaining" phase - talking about "compromise". Sorry, but markets don't do "compromise". Markets do COMPETITION. Markets do winner-takes-all. The whitepaper doesn't talk about "compromise" - it says that 51% of the hashpower determines WHAT IS BITCOIN.
They've finally entered the Kübler-Ross "bargaining" phase - now they're begging for some kind of "compromise". But actually, markets aren't about compromise. Markets are about competition. Markets are about winner-takes-all. And the Bitcoin whitepaper never mentions anything about "compromise". It simply says that 51% of the hashpower determines what is Bitcoin. And as we know - the best coin will win. Which will probably be Bitcoin Unlimited with its market-based blocksizes - and not SegWit with its 1.7MB centrally planned blocksize based on a dangerous anyone-can-spend spaghetti-code soft-fork. Let's review how this played out:
Core/Blockstream accepted $76 million in "fantasy fiat" from the "legacy ledger" of central bankers via their buddies at AXA.
And Core/Blockstream accepted censorship on the sad subreddit of r\bitcoin.
And lo and behold, Core/Blockstream's reliance on fiat funding and central planning and censorship has culminated in this pathetic piece of shit called SegWit, with the following worthless "features" that nobody even wants:
Yet-another centrally-planned 1.7MB maybe-someday blocksize - combined with some random arbitrary 1-to-4 "discount" that nobody asked for,
Fixes for low-priority non-problems like malleability and quadratic hashing,
By listening to real people in the actual market, and by following Satoshi's principles as stated in the whitepaper, Bitcoin Unlimited has been able to (surprise! surprise!) offer what real people in the actual market actually want - which is currently:
FlexTrans is much better than SegWit Also, these independent, non-fiat-financed devs developed Flexible Transactions, which is way better than SegWit. Flexible Transactions can easily fix malleability and quadratic hashing - while also introducing a simple, easy-to-use, future-proof tag-based format similar to JSON or HTML permitting future upgrades without the need for a hard fork. So Flexible Transactions provides the same things as SegWit - without the dangerous mess of SegWit's "anyone-can-spend" soft-fork hack - which Core/Blockstream tried to force on everyone - because they want to take away our right to vote via a hard fork - because they know that if we actually had a hard fork a/k/a full node referendum, everyone would vote against Core/Blockstream. The market wants to decide the blocksize So more and more of the smart, non-Blockstream-aligned miners, starting with ViaBTC and now including many others, have been adopting Bitcoin Unlimited - because they understand that:
Market-based blocksizes are the right, consensus-based mechanism to provide simple and safe on-chain scaling to solve the urgent problems of transaction delays and network congestion - now and in the future
Every increase in the blocksize roughly corresponds to the same increase squared in terms of price
ie 2x bigger blocks will lead to 4x higher price, 3x bigger blocks will correspond with 9x higher price, etc. - which means that bigger blocks will make everyone happy: more profits for miners, and no more high fees or transaction delays for users.
Now Core/Blockstream are starting to bitch and moan and beg about "compromise" And actually, we couldn't answer "Sorry it's too late for compromise" even if we wanted to. Because markets and economics and cryptocurrencies aren't about compromises. Markets are about competition - they're about winner-takes-all. Nakamoto Consensus is about 51% of the hashpower decides what the rules are. Imagine if Yahoo Email were to suddenly start begging with Google Mail for "compromise". What would that even mean in the first place?? Yahoo wrote crappy email code - based on their crappy corporate culture - so the market abandoned their crappy (and buggy and insecure) email service. Core/Blockstream is similar in some ways to Yahoo. They wrote crappy code - because they have a crappy "corporate culture" - because they accept millions of dollars in fiat from central bankers at places like AXA - and because they accept censorship on shit-forums like r\bitcoin - which is why they have no clue about the real needs of real people in the real market in the real world. Censorship and fiat made Core/Blockstream fragile and out-of-touch Core/Blockstream devs enjoy the "luxury" of being able to put their head in the sand and hide from the reality of the "shreaking" masses of actual people actually trying to use Bitcoin, because:
They get millions of dollars in fiat shoveled to them by central bankers,
They conduct their "debates" in the fantasy-land of the shit-forum r\bitcoin where all the important comments get deleted and all the intelligent posters got banned long ago - including quotes from Satoshi.
And then (surprise! surprise!) the following happened:
At any moment now, at the Schelling point of our own choosing, more hashpower can also "dump Core" and start using Bitcoin Unlimited - which is why everyone involved with Core/Blockstream is now shitting in their pants.
But in a decentralized, permissionless, open-source system like Bitcoin, there is not a single thing that CEO Adam Back u/adam3us and CTO Greg Maxwell u/nullc at their shitty little AXA-funded startup Blockstream or u/theymos and u/bashco on their shitty little censored forum r\bitcoin can do to stop Bitcoin Unlimited from taking over the network - because in open-source and in economics and in markets, the best code and the best cryptocurrency wins. Everyone (except Core/Blockstream) predicted this would happen So now - predictably - the Core/Blockstream devs and their low-information supporters are all running around saying "Nobody could have predicted this!" But actually everyone has been shouting at the top of their lungs predicting this for years - including the most important old-time Bitcoin devs supporting on-chain scaling like Mike Hearn, Gavin Andresen and Jeff Garzik who were all "censored, hounded, DDoS'd, attacked, slandered & removed" - plus new-time devs like Peter Rizun u/Peter__R who provided major scaling innovations like XThin - by the vicious drooling toxic authoritarian goons involved with Core/Blockstream. Everyone has been predicting the current delays and congestion and high fees for years, out here in the reality of the marketplace, in the reality of the uncensored forums - away from Core/Blockstream's centralized back-room closed-door fiat-funded censorship-supported PowerPoint presentations in Hong Kong and Silicon Valley, away from years and years of Core/Blockstream's all-talk-no-action scaling stalling conferences. The Honey Badger of Bitcoin doesn't give a fuck about "compromise" and "censorship" and "central planning". The Honey Badger of Bitcoin doesn't give a fuck about yet-another centrally planned blocksize (Now with 1.7MB! SegWit is scaling!TM) which some economically ignorant fiat-funded dev team happened to pull out of their ass and bundle into a radical and irresponsible spaghetti-code SegWit soft-fork. Markets aren't about "compromise". Markets are about competition. As u/ForkiusMaximusrecently pointed out: The market couldn't even give a fuck if it wanted to - because markets and cryptocurrencies are not about the politics of "compromise" - they're about the economics of competition. Markets are about decentralization, and they're about Nakamoto Consensus, where 51% of the hashpower decides the rules and everyone else either gets on the bandwagon or withers away watching their hashpower and coin price sink into oblivion. So, anyone who even brings up the topic of "compromise" is simply showing that they have a fundamental misunderstanding of how markets work, and how Nakamoto Consensus works. This actually isn't very surprising. Blockstream CEO Adam Back u/adam3us and Blockstream CTO Greg Maxwell u/nullc and all the rest of the so-called "Core devs" and all their low-information hangers-on like the economic idiot Blockstream founder Mark Friedenbach u/maaku7 have never really understood Bitcoin or markets. And that's fine and normal. Plenty of individuals don't understand markets very well. But such people simply lose their own money - and they generally don't get put in charge of losing $20 billion of other people's money. Markets don't need managers or central planners. Markets run very well on their own - and they don't like central planning or censorship. Now Core/Blockstream has finally entered the Kübler-Ross "bargaining" phase So now some people at Core/Blockstream and some of their low-information supporters have have started bitching and moaning and whining about "compromise", as they sink into the Kübler-Ross "bargaining" phase - while their plans are all in shambles, and they've failed in their attempts to hijack our network and our currency. Meanwhile, the Honey Badger of Bitcoin doesn't give a fuck about a bunch of central planners and censors whining about "compromise". Bitcoin Unlimited just keeps stealing more and more hashpower away from Core - until the day comes when we decide to fork their ass into the garbage heap of shitty, failed alt-coins. Fuck Blockstream/Core and the central bankers and censors they rode in on We told them for years that they were only shooting themselves in the foot with their closed-door back-room fiat-financed wheeling and dealing and their massive censorship. We told them they were only giving themselves enough rope to hang themselves with. Now that it's actually happening, we couldn't say "it's too late for compromise" even if we wanted to - because there is no such thing as "compromise" in markets or cryptocurrencies. Markets are all about competition And Bitcoin is all about 51% of the hashpower.
Bitcoin Core decided to bet on hard-coded centrally planned 1.7MB blocksize based on a a shitty spaghetti-code soft-fork. That's their choice. They made their bed now let them lie in it.
Meanwhile, Bitcoin Unlimited decided to bet on market-based blocksizes. And that's the market's choice. Bitcoin Unlimited listened to the market - and (suprise! surprise!) that's why more and more hashpower is now mining Bitcoin Unlimited blocks.
Yes, Bitcoin was always supposed to be gold 2.0: digital gold that you could use like cash, so you could spend it anywhere without needing banks and gold notes to make it useful. So why is Core trying to turn it back into gold 1.0? (112 points, 85 comments)

Bitcoin Core 0.10.0 released | Wladimir | Feb 16 2015
Wladimir on Feb 16 2015: Bitcoin Core version 0.10.0 is now available from: https://bitcoin.org/bin/0.10.0/ This is a new major version release, bringing both new features and bug fixes. Please report bugs using the issue tracker at github: https://github.com/bitcoin/bitcoin/issues The whole distribution is also available as torrent: https://bitcoin.org/bin/0.10.0/bitcoin-0.10.0.torrent magnet:?xt=urn:btih:170c61fe09dafecfbb97cb4dccd32173383f4e68&dn;=0.10.0&tr;=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce&tr;=udp%3A%2F%2Ftracker.publicbt.com%3A80%2Fannounce&tr;=udp%3A%2F%2Ftracker.ccc.de%3A80%2Fannounce&tr;=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr;=udp%3A%2F%2Fopen.demonii.com%3A1337&ws;=https%3A%2F%2Fbitcoin.org%2Fbin%2F Upgrading and downgrading 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). Downgrading warning Because release 0.10.0 makes use of headers-first synchronization and parallel block download (see further), the block files and databases are not backwards-compatible with older versions of Bitcoin Core or other software:
Blocks will be stored on disk out of order (in the order they are
received, really), which makes it incompatible with some tools or other programs. Reindexing using earlier versions will also not work anymore as a result of this.
The block index database will now hold headers for which no block is
stored on disk, which earlier versions won't support. If you want to be able to downgrade smoothly, make a backup of your entire data directory. Without this your node will need start syncing (or importing from bootstrap.dat) anew afterwards. It is possible that the data from a completely synchronised 0.10 node may be usable in older versions as-is, but this is not supported and may break as soon as the older version attempts to reindex. This does not affect wallet forward or backward compatibility. Notable changes Faster synchronization Bitcoin Core now uses 'headers-first synchronization'. This means that we first ask peers for block headers (a total of 27 megabytes, as of December 2014) and validate those. In a second stage, when the headers have been discovered, we download the blocks. However, as we already know about the whole chain in advance, the blocks can be downloaded in parallel from all available peers. In practice, this means a much faster and more robust synchronization. On recent hardware with a decent network link, it can be as little as 3 hours for an initial full synchronization. You may notice a slower progress in the very first few minutes, when headers are still being fetched and verified, but it should gain speed afterwards. A few RPCs were added/updated as a result of this:
getblockchaininfo now returns the number of validated headers in addition to
the number of validated blocks.
getpeerinfo lists both the number of blocks and headers we know we have in
common with each peer. While synchronizing, the heights of the blocks that we have requested from peers (but haven't received yet) are also listed as 'inflight'.
A new RPC getchaintips lists all known branches of the block chain,
including those we only have headers for. Transaction fee changes This release automatically estimates how high a transaction fee (or how high a priority) transactions require to be confirmed quickly. The default settings will create transactions that confirm quickly; see the new 'txconfirmtarget' setting to control the tradeoff between fees and confirmation times. Fees are added by default unless the 'sendfreetransactions' setting is enabled. Prior releases used hard-coded fees (and priorities), and would sometimes create transactions that took a very long time to confirm. Statistics used to estimate fees and priorities are saved in the data directory in the fee_estimates.dat file just before program shutdown, and are read in at startup. New command line options for transaction fee changes:
-txconfirmtarget=n : create transactions that have enough fees (or priority)
so they are likely to begin confirmation within n blocks (default: 1). This setting is over-ridden by the -paytxfee option.
-sendfreetransactions : Send transactions as zero-fee transactions if possible
(default: 0) New RPC commands for fee estimation:
estimatefee nblocks : Returns approximate fee-per-1,000-bytes needed for
a transaction to begin confirmation within nblocks. Returns -1 if not enough transactions have been observed to compute a good estimate.
estimatepriority nblocks : Returns approximate priority needed for
a zero-fee transaction to begin confirmation within nblocks. Returns -1 if not enough free transactions have been observed to compute a good estimate. RPC access control changes Subnet matching for the purpose of access control is now done by matching the binary network address, instead of with string wildcard matching. For the user this means that -rpcallowip takes a subnet specification, which can be
a single IP address (e.g. 126.96.36.199 or fe80::0012:3456:789a:bcde)
a network/CIDR (e.g. 188.8.131.52/24 or fe80::0000/64)
a network/netmask (e.g. 184.108.40.206/255.255.255.0 or fe80::0012:3456:789a:bcde/ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff)
An arbitrary number of -rpcallow arguments can be given. An incoming connection will be accepted if its origin address matches one of them. For example: | 0.9.x and before | 0.10.x | |--------------------------------------------|---------------------------------------| | -rpcallowip=192.168.1.1 | -rpcallowip=192.168.1.1 (unchanged) | | -rpcallowip=192.168.1.* | -rpcallowip=192.168.1.0/24 | | -rpcallowip=192.168.* | -rpcallowip=192.168.0.0/16 | | -rpcallowip=* (dangerous!) | -rpcallowip=::/0 (still dangerous!) | Using wildcards will result in the rule being rejected with the following error in debug.log:
Error: Invalid -rpcallowip subnet specification: *. Valid are a single IP (e.g. 220.127.116.11), a network/netmask (e.g. 18.104.22.168/255.255.255.0) or a network/CIDR (e.g. 22.214.171.124/24).
REST interface A new HTTP API is exposed when running with the -rest flag, which allows unauthenticated access to public node data. It is served on the same port as RPC, but does not need a password, and uses plain HTTP instead of JSON-RPC. Assuming a local RPC server running on port 8332, it is possible to request:
In every case, EXT can be bin (for raw binary data), hex (for hex-encoded binary) or json. For more details, see the doc/REST-interface.md document in the repository. RPC Server "Warm-Up" Mode The RPC server is started earlier now, before most of the expensive intialisations like loading the block index. It is available now almost immediately after starting the process. However, until all initialisations are done, it always returns an immediate error with code -28 to all calls. This new behaviour can be useful for clients to know that a server is already started and will be available soon (for instance, so that they do not have to start it themselves). Improved signing security For 0.10 the security of signing against unusual attacks has been improved by making the signatures constant time and deterministic. This change is a result of switching signing to use libsecp256k1 instead of OpenSSL. Libsecp256k1 is a cryptographic library optimized for the curve Bitcoin uses which was created by Bitcoin Core developer Pieter Wuille. There exist attacks against most ECC implementations where an attacker on shared virtual machine hardware could extract a private key if they could cause a target to sign using the same key hundreds of times. While using shared hosts and reusing keys are inadvisable for other reasons, it's a better practice to avoid the exposure. OpenSSL has code in their source repository for derandomization and reduction in timing leaks that we've eagerly wanted to use for a long time, but this functionality has still not made its way into a released version of OpenSSL. Libsecp256k1 achieves significantly stronger protection: As far as we're aware this is the only deployed implementation of constant time signing for the curve Bitcoin uses and we have reason to believe that libsecp256k1 is better tested and more thoroughly reviewed than the implementation in OpenSSL.  https://eprint.iacr.org/2014/161.pdf Watch-only wallet support The wallet can now track transactions to and from wallets for which you know all addresses (or scripts), even without the private keys. This can be used to track payments without needing the private keys online on a possibly vulnerable system. In addition, it can help for (manual) construction of multisig transactions where you are only one of the signers. One new RPC, importaddress, is added which functions similarly to importprivkey, but instead takes an address or script (in hexadecimal) as argument. After using it, outputs credited to this address or script are considered to be received, and transactions consuming these outputs will be considered to be sent. The following RPCs have optional support for watch-only: getbalance, listreceivedbyaddress, listreceivedbyaccount, listtransactions, listaccounts, listsinceblock, gettransaction. See the RPC documentation for those methods for more information. Compared to using getrawtransaction, this mechanism does not require -txindex, scales better, integrates better with the wallet, and is compatible with future block chain pruning functionality. It does mean that all relevant addresses need to added to the wallet before the payment, though. Consensus library Starting from 0.10.0, the Bitcoin Core distribution includes a consensus library. The purpose of this library is to make the verification functionality that is critical to Bitcoin's consensus available to other applications, e.g. to language bindings such as [python-bitcoinlib](https://pypi.python.org/pypi/python-bitcoinlib) or alternative node implementations. This library is called libbitcoinconsensus.so (or, .dll for Windows). Its interface is defined in the C header [bitcoinconsensus.h](https://github.com/bitcoin/bitcoin/blob/0.10/src/script/bitcoinconsensus.h). In its initial version the API includes two functions:
bitcoinconsensus_verify_script verifies a script. It returns whether the indicated input of the provided serialized transaction
correctly spends the passed scriptPubKey under additional constraints indicated by flags
bitcoinconsensus_version returns the API version, currently at an experimental 0
The functionality is planned to be extended to e.g. UTXO management in upcoming releases, but the interface for existing methods should remain stable. Standard script rules relaxed for P2SH addresses The IsStandard() rules have been almost completely removed for P2SH redemption scripts, allowing applications to make use of any valid script type, such as "n-of-m OR y", hash-locked oracle addresses, etc. While the Bitcoin protocol has always supported these types of script, actually using them on mainnet has been previously inconvenient as standard Bitcoin Core nodes wouldn't relay them to miners, nor would most miners include them in blocks they mined. bitcoin-tx It has been observed that many of the RPC functions offered by bitcoind are "pure functions", and operate independently of the bitcoind wallet. This included many of the RPC "raw transaction" API functions, such as createrawtransaction. bitcoin-tx is a newly introduced command line utility designed to enable easy manipulation of bitcoin transactions. A summary of its operation may be obtained via "bitcoin-tx --help" Transactions may be created or signed in a manner similar to the RPC raw tx API. Transactions may be updated, deleting inputs or outputs, or appending new inputs and outputs. Custom scripts may be easily composed using a simple text notation, borrowed from the bitcoin test suite. This tool may be used for experimenting with new transaction types, signing multi-party transactions, and many other uses. Long term, the goal is to deprecate and remove "pure function" RPC API calls, as those do not require a server round-trip to execute. Other utilities "bitcoin-key" and "bitcoin-script" have been proposed, making key and script operations easily accessible via command line. Mining and relay policy enhancements Bitcoin Core's block templates are now for version 3 blocks only, and any mining software relying on its getblocktemplate must be updated in parallel to use libblkmaker either version 0.4.2 or any version from 0.5.1 onward. If you are solo mining, this will affect you the moment you upgrade Bitcoin Core, which must be done prior to BIP66 achieving its 951/1001 status. If you are mining with the stratum mining protocol: this does not affect you. If you are mining with the getblocktemplate protocol to a pool: this will affect you at the pool operator's discretion, which must be no later than BIP66 achieving its 951/1001 status. The prioritisetransaction RPC method has been added to enable miners to manipulate the priority of transactions on an individual basis. Bitcoin Core now supports BIP 22 long polling, so mining software can be notified immediately of new templates rather than having to poll periodically. Support for BIP 23 block proposals is now available in Bitcoin Core's getblocktemplate method. This enables miners to check the basic validity of their next block before expending work on it, reducing risks of accidental hardforks or mining invalid blocks. Two new options to control mining policy:
-datacarrier=0/1 : Relay and mine "data carrier" (OP_RETURN) transactions
if this is 1.
-datacarriersize=n : Maximum size, in bytes, we consider acceptable for
"data carrier" outputs. The relay policy has changed to more properly implement the desired behavior of not relaying free (or very low fee) transactions unless they have a priority above the AllowFreeThreshold(), in which case they are relayed subject to the rate limiter. BIP 66: strict DER encoding for signatures Bitcoin Core 0.10 implements BIP 66, which introduces block version 3, and a new consensus rule, which prohibits non-DER signatures. Such transactions have been non-standard since Bitcoin v0.8.0 (released in February 2013), but were technically still permitted inside blocks. This change breaks the dependency on OpenSSL's signature parsing, and is required if implementations would want to remove all of OpenSSL from the consensus code. The same miner-voting mechanism as in BIP 34 is used: when 751 out of a sequence of 1001 blocks have version number 3 or higher, the new consensus rule becomes active for those blocks. When 951 out of a sequence of 1001 blocks have version number 3 or higher, it becomes mandatory for all blocks. Backward compatibility with current mining software is NOT provided, thus miners should read the first paragraph of "Mining and relay policy enhancements" above. 0.10.0 Change log Detailed release notes follow. This overview includes changes that affect external behavior, not code moves, refactors or string updates. RPC:
