<div>{{current}}{{see also|Scalability FAQ}}<br />
[[Block]]s are limited to 1MB in size. Miners can mine blocks up to the 1MB fixed limit, but any block larger than 1MB is invalid. This limit cannot be modified without a hard fork. To prevent Bitcoin from temporarily or permanently splitting into separate payment networks ("altcoins"), hard forks require adoption by nearly all [[Full node#Economic_strength|economically active]] full nodes.<br />
<br />
== Arguments in favor of increasing the blocksize ==<br />
* More transactions per second<br />
* Off-chain solutions are not yet ready to take off the load from the main blockchain.<br />
<br />
== Unclear Arguments ==<br />
* Increased blocksize will leave space for extensions like Mastercoin, Counterparty, etc.<br />
** Neutral: Bitcoin competitors will have lower fees<br />
** Negative: Bitcoin full nodes are forced to use more resources that don't support Bitcoin<br />
* Small blocks eventually will require higher fees for fast confirmations.<br />
** Positive: It will no longer be cheap to spam transactions such as Satoshi Dice bets<br />
** Positive: Fees will not be zero. This is eventually a necessity in order to incentivize miners and secure the mining ecosystem<br />
** Negative: Bitcoin may look unattractive to new users with high fees<br />
** Negative: High fees may stop or reverse global adoption, investment, development, support and centralization{{clarification needed}}<br />
** Negative: Bitcoin users pay higher fees<br />
<br />
== Arguments in opposition to increasing the blocksize ==<br />
* A hard fork requires waiting for sufficient consensus.<br />
* Risk of catastrophic consensus failure<ref>https://www.mail-archive.com/bitcoin-development@lists.sourceforge.net/msg08276.html</ref>{{clarification needed}}<br />
* An emergency hard fork that can achieve consensus can be deployed on a short time period if needed.<ref>[https://www.reddit.com/r/Bitcoin/comments/392m43/mike_hearn_blocksize_debate_at_the_breaking_point/cs00wdd How to raise block size in a short time], Peter Todd, Reddit /r/Bitcoin, 9 June 2015</ref><br />
* Orphan rate amplification, more reorgs and double-spends due to slower propagation speeds.<br />
* European/American pools at more of a disadvantage compared to the Chinese pools{{why}}<br />
* "Congestion" concerns can be solved with mempool improvements including transaction eviction.<br />
* No amount of max block size would support all the world's future transactions on the main blockchain (various types of off-chain transactions are the only long-term solution)<br />
* Fast block propagation is either not clearly viable, or (eg, IBLT) creates centralised controls.<br />
* A low blocksize limit encourages higher transactions fees to incentivize miners ("let a fee market develop"). Counter-argument: [https://dl.dropboxusercontent.com/u/43331625/feemarket.pdf A Transaction Fee Market Exists Without a Block Size Limit]<br />
<br />
=== Damage to decentralization ===<br />
* Larger blocks make full nodes more expensive to operate.<br />
* Therefore, larger blocks lead to less hashers running full nodes, which leads to centralized entities having more power, which makes Bitcoin require more trust, which weakens Bitcoins value proposition.<br />
* Bitcoin is only useful if it is decentralized because centralization requires trust. Bitcoins value proposition is trustlessness.<br />
* The larger the hash-rate a single miner controls, the more centralized Bitcoin becomes and the more trust using Bitcoin requires.<br />
* Running your own full node while mining rather than giving another entity the right to your hash-power decreases the hash-rate of large miners. Those who have hash-power are able to control their own hash power if and only if they run a full node.<br />
* Less individuals who control hash-power will run full nodes if running one becomes more expensive<ref>https://www.weusecoins.com/why-blocksize-limit-keeps-bitcoin-free-decentralized/</ref>.<br />
<br />
==Proposals==<br />
===BIP 100===<br />
Periodically change the limit based on observed block size, but never go larger than 32MB.<br />
===BIP 101===<br />
{{seealso|Bitcoin XT}}<br />
Increase to 8 MB on January 11, 2016, and double the limit every two years.<br />
===BIP 102===<br />
Increase to 2 MB on November 11, 2015.<br />
===BIP 103===<br />
Increase by 17.7% annually until 2063.<br />
<br />
== Entities positions ==<br />
Positions below are based on a suggested fixed block size increase to 20MiB. Positions against these larger blocks do not necessarily imply that they are against an increase in general, and may instead support a smaller and/or gradual increase.<br />

<div>The '''testnet''' is an alternative Bitcoin [[block chain]], to be used for testing. Testnet coins are separate and distinct from actual bitcoins, and are never supposed to have any value. This allows application developers or bitcoin testers to experiment, without having to use real bitcoins or worrying about breaking the main bitcoin chain.<br />
<br />
Run bitcoin or bitcoind with the -testnet flag to use the testnet (or put testnet=1 in the bitcoin.conf file).<br />
<br />
There have been three generations of testnet. Testnet2 was just the first testnet reset with a different genesis block, because people were starting to trade testnet coins for real money. '''Testnet3''' is the current test network. It was introduced with the 0.7 release, introduced a third genesis block, a new rule to avoid the "difficulty was too high, is now too low, and transactions take too long to verify" problem, and contains blocks with edge-case transactions designed to test implementation compatibility.<br />
<br />
==Differences==<br />
* Default Bitcoin network protocol listen port is 18333 (instead of 8333)<br />
* Default RPC connection port is 18332 (instead of 8332)<br />
* Bootstrapping uses different DNS seeds.<br />
* A different value of ADDRESSVERSION field ensures no testnet Bitcoin addresses will work on the production network. (0x6F rather than 0x00)<br />
* The protocol message header bytes are 0x0B110907 (instead of 0xF9BEB4D9) <br />
* Minimum [[difficulty]] of 1.0 on testnet is equal to difficulty of 0.5 on mainnet. This means that the mainnet-equivalent of any testnet difficulty is half the testnet difficulty. In addition, if no block has been found in 20 minutes, the difficulty automatically resets back to the minimum for a single block, after which it returns to its previous value.<br />
* A new genesis block<br />
* The IsStandard() check is disabled so that non-standard transactions can be experimented with.<br />
<br />
==Genesis Block==<br />
<br />
Testnet uses a different genesis block to the main network. You can find it [https://www.biteasy.com/testnet/blocks/000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943 here] or [http://blockexplorer.com/testnet/b/0 here].<br />

There have been three generations of testnet. Testnet2 was just the first testnet reset with a different genesis block, because people were starting to trade testnet coins for real money. '''Testnet3''' is the current test network. It was introduced with the 0.7 release, introduced a third genesis block, a new rule to avoid the "difficulty was too high, is now too low, and transactions take too long to verify" problem, and contains blocks with edge-case transactions designed to test implementation compatibility.<br />
<br />
==Differences==<br />
* Default Bitcoin network protocol listen port is 18333 (instead of 8333)<br />
* Default RPC connection port is 18332 (instead of 8332)<br />
* Bootstrapping uses different DNS seeds.<br />
* A different value of ADDRESSVERSION field ensures no testnet Bitcoin addresses will work on the production network. (0x6F rather than 0x00)<br />
* The protocol message header bytes are 0x0B110907 (instead of 0xF9BEB4D9) <br />
* Minimum [[difficulty]] of 1.0 on testnet is equal to difficulty of 0.5 on mainnet. This means that the mainnet-equivalent of any testnet difficulty is half the testnet difficulty. In addition, if no block has been found in 20 minutes, the difficulty automatically resets back to the minimum for a single block, after which it returns to its previous value.<br />
* A new genesis block<br />
* The IsStandard() check is disabled so that non-standard transactions can be experimented with.<br />
<br />
==Genesis Block==<br />
<br />
Testnet uses a different genesis block to the main network. You can find it [https://www.biteasy.com/testnet/blocks/000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943 here] or [http://blockexplorer.com/testnet/b/0 here].<br />
The testnet was reset with a new genesis block for the 0.7 bitcoin release.<br />
<br />
==Mining==<br />
[[solo.ckpool]] has a testnet bitcoin solo mining implementation available, without the need to set up bicoind locally.<br />

<br />
==Problem==<br />
<br />
Lazy web designer wants to use bitcoins without dealing with installing bitcoin on a server, installing a shopping cart interface, or using ugly merchant services with callbacks.<br />
<br />
==Solution for sending bitcoins==<br />
<br />
<strike>Use the [https://mtgox.com/support/tradeAPI MtGox API] which allows you to use the offchain payment network.</strike><br />
<br />
==Solution for receiving bitcoins==<br />
# Input a list of bitcoin receiving addresses to your database<br />
# Give a bitcoin address to a potential customer<br />
# Have the customer tell you when they have sent the coins and have at least 1 confirmation (you can choose a number higher than 1 if you are worried about double-spending)<br />
# Check blockexplorer to see if they sent the right amount (i.e. http://blockexplorer.com/q/getreceivedbyaddress/19hMEAaRMbEhfSkeU4GT8mgSuyR4t4M6TH/1) - the /1 is the number of confirmations you require<br />
# Give them what they paid for<br />
# After a reasonable amount of time has passed, you can re-use the address for another customer<br />

<br />
BlockExplorer is a service that is provided by a private party. There is no guarantee that the information provided by BlockExplorer matches the blockchain.<br />
<br />
There have not been any reports that BlockExplorer has reported transaction data incorrectly.<br />
<br />
===Double Spending===<br />
<br />
A merchant is exposed to a [[double-spending]] attack when recognizing a payment before it has been [[confirmation|confirmed]] with a sufficient number of blocks.<br />
<br />
For an attacker to be successful with this double spend tactic a significant effort is required and thus the risk of this attack being made against the typical retail merchant is pretty minimal. It would not be advisable for a merchant with little to no recourse against an attacker to accept payment without a sufficient number of confirmations however.<br />
<br />
Note that this attack can be performed no matter which API or client is being used.<br />

<div>[[File:blockchain.png|thumb|Blocks in the main chain (black) are the longest series of blocks that go from the genesis block (green) to the current block. Purple blocks are blocks that are not in the longest chain and therefore not used.]]<br />
<br />
A '''block chain''' is a transaction database shared by all [[Node|nodes]] participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every [[transaction]] ever executed in the currency. With this information, one can find out how much value belonged to each [[address]] at any point in history.<br />
<br />
Every [[Blocks|block]] contains a [[hash]] of the previous block. This has the effect of creating a chain of blocks from the [[genesis block]] to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make [[double-spending]] of bitcoins very difficult. The block chain is the main innovation of Bitcoin.<br />
<br />
Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block.<br />
<br />
For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes.<br />
<br />
Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists.<br />
<br />
These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children.<br />
<br />
Because a block can only reference one previous block, it is impossible for two forked chains to merge.<br />
<br />
It's possible to use the block chain algorithm for non-financial purposes: see [[Alternative chain]].<br />
<br />
The block chain is broadcast to all nodes on the networking using a flood protocol: see [[Block chain download]].<br />
