There are treacherous passes in any technological revolution.
Some people in the blockchain industry have pointed out that blockchain has become overhyped, when, in reality, the technology has limitations and is inappropriate for many digital interactions.
But through research and development, success and failure, and trial and error, we’ve learned the current issues and limitations of blockchains.
Complexity
Blockchain technology involves an entirely new vocabulary.
It has made cryptography more mainstream, but the highly specialized industry is chock-full of jargon. Thankfully, there are several efforts at providing glossaries and indexes that are thorough and easy to understand.
Network size
Blockchains (like all distributed systems) are not so much resistant to bad actors as they are ‘antifragile’ – that is, they respond to attacks and grow stronger.
This requires a large network of users, however. If a blockchain is not a robust network with a widely distributed grid of nodes, it becomes more difficult to reap the full benefit.
There is some discussion and debate about whether this a fatal flaw for some permissioned blockchain projects.
Transaction costs, network speed
Bitcoin currently has notable transaction costs after being touted as ‘near free’ for the first few years of its existence.
As of late 2016, it can only process about seven transactions per second, and each transaction costs about $0.20 and can only store 80 bytes of data.
There’s also the politically charged aspect of using the bitcoin blockchain, not for transactions, but as a store of information. This is the question of ‘‘bloating’ and is often frowned upon because it forces miners to perpetually reprocess and rerecord the information.
Human error
If a blockchain is used as a database, the information going into the database needs to be of high quality. The data stored on a blockchain is not inherently trustworthy, so events need to be recorded accurately in the first place.
The phrase ‘garbage in, garbage out’ holds true in a blockchain system of record, just as with a centralized database.
Unavoidable security flaw
There is one notable security flaw in bitcoin and other blockchains: if more than half of the computers working as nodes to service the network tell a lie, the lie will become the truth. This is called a ‘51% attack’ and was highlighted by Satoshi Nakamoto when he launched bitcoin.
For this reason, bitcoin mining pools are monitored closely by the community, ensuring no one unknowingly gains such network influence.
Politics
Because blockchain protocols offer an opportunity to digitize governance models, and because miners are essentially forming another type of incentivized governance model, there have been ample opportunities for public disagreements between different community sectors.
These disagreements are a notable feature of the blockchain industry and are expressed most clearly around the question or event of ‘forking’ a blockchain, a process that involves updating the blockchain protocol when a majority of a blockchain’s users have agreed to it.
These debates can be very technical, and sometimes heated, but are informative for those interested in the mixture of democracy, consensus and new opportunities for governance experimentation that blockchain technology is opening up.

However, with Bitcoin we are trying to build a decentralized currency system, so we will need to combine the state transition system with a consensus system in order to ensure that everyone agrees on the order of transactions. Bitcoin's decentralized consensus process requires nodes in the network to continuously attempt to produce packages of transactions called 'blocks'. The network is intended to produce roughly one block every ten minutes, with each block containing a timestamp, a nonce, a reference to (ie. hash of) the previous block and a list of all of the transactions that have taken place since the previous block. Over time, this creates a persistent, ever-growing, 'blockchain' that constantly updates to represent the latest state of the Bitcoin ledger.bitcoin background bitcoin rotator tether bitcointalk tether программа

Bitcoin shares the monetary properties that caused gold to emerge as a monetary medium, but it also improves upon gold’s flaws. While gold is relatively scarce, bitcoin is finitely scarce and both are extremely durable. While gold is fungible, it is difficult to assay; bitcoin is fungible and easy to assay. Gold is difficult to transfer and highly centralized. Bitcoin is easy to transfer and highly decentralized. Essentially, bitcoin possesses all of the desirable traits of both physical gold and the digital dollar combined in one, but without the critical flaws of either. When evaluating monetary mediums, first principles are fundamental. Ignore the conclusion or end point, and start by asking yourself: if bitcoin were actually scarce and finite, ignoring that it is digital, could that be an effective measure of value and ultimately a store of value? Is scarcity a sufficiently powerful property that bitcoin could emerge as money, regardless of whether the form of that scarcity is digital?форк ethereum bitcoin sec обмен monero monero coin ethereum видеокарты bitcoin attack bitcoin farm keystore ethereum
