The block is a consecutive chain of blocks with information about the transactions that have been committed. It is believed that this information can not be unnoticeably changed in hindsight, since this will affect all subsequent blocks. For the first time the technology of blocking was implemented in the system of crypto-currency, but later it was interested in banks and other organizations that conduct and track various transactions.
This isn't really news.
The real question is, why would you follow links written in the blockchain?
I don't even click links that friends send me, unless it is from a known website.

Hi,
The main problem is this: If you're downloading the full blockchain you're indirectly storing child pornography on your computer.
And storing child pornography on your computer (even without knowing it) may lead to trouble and I guess you know how well politician and prosecuting authorities are familiar with the blockchain, decentralization etc.

Except its FUD spread for 5-6 years already
https://news.bitcoin.com/no-isnt-child-porn-bitcoin-blockchain/
Guess what, because of https://en.wikipedia.org/wiki/Steganography any picture you download on internet (or even broader, any FILE) can have hidden links
to child porn inside it...oh no, lets ban Internet
Definitely feels a bit fuddy, but then again it may be an issue that we will have to take a look at in the future. The Governments of the World will 100% definitely attempt to step in and stop CP other damaging information/pictures/files/etc to be written/stored on the blockchain.

Researchers at RWTH Aachen University in Germany recently downloaded the entire Bitcoin blockchain and discovered it contains links to child pornography websites and a possible image of a “mildly nude” minor. They were investigating the blockchain’s non-financial data to uncover “objectionable” content but stumbled across the appalling surprise. The researchers provided their findings in a new paper during the Financial Cryptography and Data Security 2018 conference in late February.
At the time of the download, Bitcoin’s blockchain weighed at a hefty 122GB in size. The researchers concluded that only 1.4 percent of all blockchain transactions contain non-financial data, which consumes a mere 118.5MB of the entire blockchain volume. Even more, the transactions with data they could actually read weighed a mere 22.6MB. This is where they stumbled across the child pornography.
A blockchain typically records transactions using Bitcoins or other cryptocurrencies. It’s a decentralized ledger that keeps track of anonymous purchases between buyer and seller. It’s secure because the technology is based on cryptography, thus data can’t be modified or traced back to a specific individual.
But users can inject the blockchain with non-financial data by encoding that data as a standard transaction. Currently, there are four services that can inject non-financial data into the blockchain: CryptoGraffiti, Satoshi Uploaded, P2SH Injectors, and Apertus.
After their investigation, the researchers unearthed 274 links to child pornography sites. But the problem goes beyond child pornography: The blockchain can also be used to store pirated copyrighted content, malware, stolen personal data and/or images, leaked government information, and other “illegal and condemned” content.
The real kicker is how a blockchain works: Because it is decentralized, it relies on a network of millions of PCs scattered across the globe rather than one specific bank or government institution. Thus, given that anyone can inject the blockchain with non-financial data, controversial and possibly illegal content can be problematic for everyone maintaining the blockchain.
“Since all blockchain data is downloaded and persistently stored by users, they are liable for any objectionable content added to the blockchain by others. Consequently, it would be illegal to participate in a blockchain-based system as soon as it contains illegal content,” the paper states.
Because of a blockchain’s anonymous nature, countries will need to add this technology to their list of platforms that can’t post illegal content, such as filesharing networks, newsgroups, online storage, social networks, and so on. More specifically, they need to deem blockchain data illegal that can be converted to “visual representation of illegal content” by anyone with access to the blockchain.”A plethora of fundamentally different methods to store non-financial–potentially objectionable–content on the blockchain exists in Bitcoin. As of now, this can affect at least 112 countries in which possessing content such as child pornography is illegal. This especially endangers the multi-billion-dollar markets powering cryptocurrencies such as Bitcoin,” the paper adds.
Unfortunately, due to the cryptographic nature of the blockchain, methods to remove illegal content is unknown at the moment.

My gut feeling tells me that this is another cheap, unsubstantiated attack by the establishment aimed against Bitcoin and other cryptos. Even if proven real, they most likely linked to those sites themselves - sites that exist outside of the blockchain. In addition, it doesn't take away from the fact that fiat currencies and some of the networks it support have been the greatest enablers of child pornography on planet earth. So fiat currencies should be banned without delay in order to protect the public.
An individual can store everything in blockchain cause it is decentralized.
It could be a fake news a paradox to mislead bitcoin lover to stay away from their investment, and I'll have to admit it is a good move.
an enthusiast will do everything to get hold a certain amount of bitcoin however with the current price it is highly unlikely to happen in order for the said enthusiast to hold a large volume of BTC oneself need to advertise such disgusting true feature of blockchain or similarly a more unpleasant concepts of bitcoin as a whole.
P.S Unless someone debunk my statement I must admit that it is a genuine 'impornation'

thats real due to decentralize blockchain. and due to become anonymous. many people abuse what is the advantages of this.. dark web /deep web also for sure using this for personal reason.. one of the example if im right is the owner of silkroad at darkweb.
