This block size debate might lead to a fork, or a change of the bitcoin protocol in order to modify the structure (and also the size, of course) of the blocks. A soft fork is an update of the bitcoin protocol that causes an only temporary divergence within the blockchain: old nodes won’t be able to recognize the new blocks upgraded only for a. The current block size limits the Bitcoin use to transactions per second. This can force regular users to compete for transactions by increasing the fees, pricing some users out of the network, once Bitcoin is popular enough. A hard fork requires waiting for sufficient consensus. Risk of catastrophic consensus failure. Bitcoin Classic In its first 8 months, Bitcoin Classic promoted a single increase of the maximum block size from one megabyte to two megabytes. In November this changed and the project moved to a solution that moved the limit out of the software rules into the hands of the miners and nodes.

It also dictates the system requirements for participating in Bitcoin without needing to trust another party. Letter published at Change. In their letter, they emphasize that they played an important role in the development of bitcoin. Over the past five years, we have written code, we have conducted more than fifty bitcoin updates and reviewed more than forty-five formal proposals to improve the performance of bitcoin, its reliability and its scalability.
Technical discussions, sometimes heated, have always focused on improving bitcoin. Much has already been done, but" a number of key problems still stand", the authors of the open letter. But the most important thing, in their opinion — caution, because bitcoin "means a lot to many people", and at stake billions of dollars of user assets.
Moreover, it is very important to increase the maximum block size without damaging "the most important features of bitcoin — decentralization, reliability and openness to updates".
Insisting that they years considered the question of the block size, the authors of the letter imply that there is no one who could better judge of this matter than themselves.
But in the letter they report that they will look for solutions only together with other members of the bitcoin community. The authors report on two upcoming seminars on increasing the maximum size of the bloc, which they believe will lead to a "technical consensus" in the ongoing discussion. The authors of the letter Express confidence that"working together, we will be able to agree on a better way of action.
The letter is signed by many developers of the bitcoin core software. But under it there is no signature of Andresen Gavin and Mike Hearn. Two of the most famous bitcoin developers believe that they have already found a solution to the problem.
They proposed BIPa change in the bitcoin code, increasing the maximum block size in the block chain to 8 megabytes since the beginning of , followed by a doubling every two years — so the block size will be 16 megabytes in , 32 megabytes in and so on. Faced with doubts about the need for such changes, Mike hirn decided to implement the development and create a new version of bitcoin, Bitcoin XT , based on BIP The miners had a choice - either not to change anything and stay with the size of the block of 1 megabyte, or fully accept Bitcoin XT, based on the ideas of Andrisen and hirn.
But despite the open letter in support of BIP and Gavin Andresen , signed by representatives of the largest bitcoin companies, the largest mining pools supported the third decision-BIP, proposed by Jeff Garzik , and provides that the size of the block changes every three months in accordance with the result of the vote miners.
There are many valid reasons to want a bigger block size. The current block size limits the Bitcoin use to transactions per second. This can force regular users to compete for transactions by increasing the fees, pricing some users out of the network , once Bitcoin is popular enough.
While a bigger block size is defended by many. There are also reasonable arguments for the concervative side that belives blocks should be limited to 1 MB. For broader coverage of this topic, see Bitcoin. Part of this section is transcluded from Fork blockchain. Main article: Lightning Network.
