One of the biggest problems facing Blockchain is its lack of scale

Here's what you need to know about the problems that come with technology that supports Bitcoin and other cryptocurrencies.

In order for the world economy to continue to grow, we need to develop a digital infrastructure to support the speed and volume in which we share information. The data infrastructure must be scalable and deployable as the needs of our digital age continue to evolve.

Although blockchain is somehow the "new guy on the block", he has thrilled the business world. According to a survey conducted by Gartner, 66% of respondents said they believe that the blockchain represents a business break and 5% is willing to spend more than $ 10 million on technology.

Blockchain has many uses and implications, however, the first mainstream application we have seen is the cryptocurrency. But the initial design of cryptocurrencies was not built for widespread use and adoption

For Bitcoin and Ethereum compete with traditional systems like Visa and PayPal, they need to step up their game with their transaction times. As explained by Crypto's trading company, Coindesk, "While PayPal handles 193 transactions per second and Visa handles 1667 transactions per second, Ethereum only executes 20 transactions per second while Bitcoin handles seven transactions per second, the only way to improve these numbers

Scalability obstacles created by mining

When dealing with Bitcoin and Ethereum, a transaction is granted only when a miner (the person whose computer has processed the code behind the currency) puts the transaction data in the blocks that they extracted.

Let's say that Stephen wants to send Andrew 10 BTC (bitcoin).) He will send the transaction data to the miners, the miner will put it in their block and then the transaction will be completed.

However, with the increase in Bitcoin's popularity, this process takes more time, and there is the issue of transaction fees when miners pull out a block, they become guardians of that block. In order for transactions to pass, users will have to pay a toll to that gatekeeper. This "toll" is referred to as a transaction fee. This commission creates problems during resizing because it creates an additional barrier.

What about Ethereum? In theory, Ethereum should process 1,000 transactions per second. However, in practice, Ethereum is limited by a limit of 6.7 million gas – the amount of computational effort required by the recipient side of the transaction – on each block.

Here's how to understand what "gas" means. Stephen has issued a smart contract for Andrew. Andrew sees that the elements of the contract will cost X amount of gas. As a result, it will charge Stephen for the amount of gas consumed. It's like letting your friend borrow your car and getting them to repay the amount of gas that was used when he drove.

It has emerged a lot more, because until recently the adoption of cryptocurrencies has not spread. Ethereum has exploded in popularity around December 2017 through a game called CryptoKitties (where users buy digital cats and breed them). The popularity of the game brought to the fore the problem of scalability, as documented in this article Mashable .

Here are some terms you should know about resizing the blockchain. [19659009] Sharding

Sharding is the division of the block verification process and the operation of parallel subcommittees to group the completed data. Zilliqa is a platform that uses sharding. It has been shown to handle 2,400 transactions per second with the goal of matching the Visa average to 8,000 transactions per second, according to The-Blockchain .

Perhaps most important, Zilliqa efficiently reacts to scalability needs because its throughput increases with its network size, unlike bitcoin clogging with transactions. With a node size equivalent to Ethereum, Zilliqa predicts that it could handle twice the Visa transactions per second.

Hard fork

When a platform drastically moves away from its initial direction of the platform, it is called a "hard fork." "Preceding the autonomous decentralized organization hacking on the Ethereum network (where $ 53 million Crowdfunded cryptocurrencies have been "stolen", as reported by Bitcoin.com.) Ethereum has taken a bifurcation to recover the money and has continued as Ethereum Classic, while the existing course has retained the original blockchain as Ethereum.

Bitcoin has recently adopted a fixed fork with block size limit, which means that the old and the new software are not compatible with each other and invalidate the old outputs Bitcoin has already forked previously, as with Bitcoin Cash, and there are others scheduled for this year

Segregato testimone

The proposed bitcoin forks will include all SegWit (the segregated Witness soft fork), which is a software designed to solve the malleability of transactions but also to improve the problem of limited block size. Each block has a limit size that creates a finite amount of transactions that occur on each block.

SegWit increases the block size limit to 4 MB, which means that a single block can contain records of more than 8,000 transactions. However, although the increase in locks provides a short-term respite in scalability problems, it will eventually present the same restrictions once transactions have exceeded the limit.
