This hard fork served as a great social experiment in creating money out of thin air, which is becoming the trademark of cryptocurrency. SegWit and Bitcoin Cash continue to run their own versions of blockchain, both claiming to spread the original decentralised vision. Overall, the prospects are looking good. The future SegWit2x implementations moved tension forward November this year.
The usability and widespread use of these features are still to be proven on the market. Setting the system is an important part. Stay with us for our next blogpost when we will describe a new way to fund crypto companies: ICO Initial Coin Offerings.
Your blog posts help understand different facets and nuances of Bitcoin that I would not otherwise be aware of. I would never have thought that virtual mining had an energy cost! Thanks for the comment Ginger Thanks for the comment Ginger.
Indeed vast amount of data generated in Bitcoin system might be a burden for the flexibility. Bitcoin blockchain is inefficient by design. Miners network is large generating 6 ExaHash per second and consumes a lot of energy. One transaction verified on Bitcoin network requires time more energy that a credit card swipe. Nevertheless, energy efficiency of Bitcoin block chain might not be such a big problem. Decentralized property of system might have different solutions for mutual verifications.

Decision making in decentralised systems All changes and decisions to Bitcoin and blockchain can only be implemented through the consensus of the users. SegWit implementation As 1 August approached, the uncertainty around proposals grew.

It is a significant shift in the blockchain's code, which makes the old blocks incompatible with the new chain that is created. The result of a hard fork is that the affected blockchain splits into two. Hard forks can also split a cryptocurrency network in two if they are not entirely adopted. Additionally, if enough miners, nodes, validators, or other entities within a network adopt a proposed hard fork, they may force a blockchain division.
On the other hand, soft forks entail a shift in network rules and make the updated blockchain backward compatible. This means that the data from the old blocks are incorporated into the new blocks, and the blockchain continues. Among the most concerning problems that faced Bitcoin at the time was scalability. Because block size in the Bitcoin blockchain was capped at 1 MB megabyte , there was a limit to the number of transactions the network could process per second.
Block limits create a bottleneck in transaction approval speeds. As cryptocurrencies continue to increase in popularity, this bottleneck can slow the networks down. Developers and cryptocurrency enthusiasts had been working to address this issue, but the debate over how to effectively scale the network was a difficult and contentious one. Segregated witness SegWit was proposed in late by developer Pieter Wuille.
SegWit proposed moving witness signature information—which occupied most of the available space within a block—to the coinbase transaction. This transaction is the first transaction recorded in a new block. Removing this information increased the amount of data that could be stored in a block; at the same time, a new method for determining block size was implemented—block weight units. Weight units WU allowed the Bitcoin blockchain to vary the size of the blocks based on a block weight limit of 4 million WU.
The goal of SegWit was to increase overall transaction capacity via a soft fork mechanism which would not prompt a split. Segwit2x was an attempt to increase the block size limit in megabytes to increase transaction validation and network speeds. SegWit was a soft fork suggestion—SegWit2x was a hard fork proposal.
When SegWit was introduced to the network in , it was the first of a two-stage process known as the "New York Agreement" by scalability experts and developers. Speeding up cryptocurrency transaction times remains a challenge. Projects like the Lightning Network seek to address these issues by moving smaller transactions off-chain into another layer. By increasing the block size, the SegWit2x proponents hoped to increase speed and mitigate rising transaction fees.
Leading up to the SegWit2x release date, miners and startups tended to be the most vocal supporters of the new protocol. They often argued that Bitcoin's inaction was causing competing cryptocurrencies to overtake the leading digital currency and that the existing upgrades were not sufficient to mitigate the problem.
Developers and node operators , on the other hand, often opposed the adoption. They suggested that Bitcoin should be a store of value, as opposed to a payment system. Additionally, they felt the riskiness of the new protocol outweighed the potential benefits. Some also felt that miners and enterprises would benefit disproportionally from the protocol. It was also theorized that increasing the block size would have increased the burden on node operators, who would be required to store more data.
More data meant they would be required to upgrade their systems, adding more costs. In reality, when SegWit was introduced, block sizes increased automatically depending on transaction sizes. For example, block number ,, mined on Feb. In comparison, block ,, mined on Jan. Thus, Segwit2x was unnecessary because SegWit allowed the blocks to vary in size depending on the block's weight units. SegWit2x was highly controversial partly because of its status as a hard fork , and its developers were unable to reach a consensus on its adoption.
The hard fork had initially been planned for Nov. However, on Nov. SegWit2x was perceived as a good idea by some developers and enthusiasts but not others. However, it proved to be a non-essential protocol because SegWit already increased the amount of data that could be placed into a block, which was the primary purpose for SegWit2x.
