We’re actually used to centralization, almost everywhere. It’s in our governments, in our banks, in the products we use. Centralization means that one single party (company, government, organization, or individual) is in charge of things. They have full authority and control to fix… or to manipulate, censor, and even destroy the services and platforms they offer. That’s why decentralized systems and cryptocurrencies were created: to avoid that risk.\These centralized parties offer convenience, but they also open doors that are harder to close once something goes wrong. Let’s explore, indeed, how things may go wrong in the online security realm with centralized authorities.Single Point of FailureImagine that you upload a sensitive file to A Cloud to keep it safe. Then, one day, without warning, the company behind A Cloud faces a massive fire on its servers, and all of its files are lost. It could also happen that they’re hacked, and all of their files are stolen and sold on the Darknet. A human error could cause a whole crash on their exclusive systems, too. Well, the point is that many things could go wrong, because they’re a single point of failure.When everything runs through one hub, that hub becomes a pressure point. If it breaks, the whole structure can wobble or collapse. This can happen in the crypto space as well, with centralized crypto exchanges and similar custodial companies. A single server outage can pause trading, block withdrawals, or lock users out without warning. Other times, mere negligence or deliberate manipulation can happen, leading to loss of funds.\In decentralized ledgers, responsibilities are spread across many, many nodes. If one of them fails (or becomes dishonest) for any reason, we’d still have hundreds or thousands more supporting the network. That makes them harder to shut down with just one hit. On the other hand, when a centralized system fails, recovery depends on the same authority that failed in the first place. That doesn't always end well.Attractive Target for Attacker & Insider ThreatsThis is a no-brainer. If a certain company or platform holds large amounts of money in one solitary place, they’re a giant, alluring target. The team in custody of those funds needs to invest a lot in security, or any cyber-attacker will break through their walls. Sadly, crypto history has plenty of examples. Some reports have registered over 220 “major [hacking] incidents” on centralized and even decentralized exchanges. Only the top ten attacks have managed to rob over $4.3 billion since 2019.Besides, threats don’t always come from strangers: insiders can be just as dangerous or more. Employees, founders, or team members with privileged access can move funds, change records, or leak sensitive data. Or simply die with the knowledge of all private keys, like the infamous case of QuadrigaCX. Crypto companies try to reduce this risk with multi-signature wallets and strict access policies, but that shouldn't happen with really decentralized ledgers.\Hackers rarely bother to attack the strongest crypto networks, because their decentralized nature (too many nodes) makes this type of attack almost impossible to carry out. To steal directly from a distributed ledger, the entire history would have to be changed from the transaction you want to double-spend. The cost of performing such a feat is usually not worth it.Censorship and ControlIf a central party makes all decisions, they can also decide who can use their system, how, and when. Their reasoning and policies aren’t always “fair,” either. Sometimes it happens due to legal pressure, but other times it can be completely arbitrary. In the financial world, it’s quite common that banks have full control over your money. If they go bankrupt or the government orders them, for any reason, to manipulate those funds, then your savings may be gone for good.\Payment platforms are also known for censoring accounts linked to “controversial” activities, including 18+ content and political protests, all across the world. PayPal is especially infamous for freezing or blocking accounts without clear explanations. In crypto, centralized exchanges can suspend withdrawals or restrict certain addresses, too —again, for any reason.It’s supposed that rules are there to protect us against fraud or illegal activity, but they also create uncertainty and barriers for ordinary users. Funds that sit under someone else’s authority can be paused without much warning. That risk becomes more visible during political or economic tension.Lack of TransparencyThe thing is, you don’t know what the companies behind A Cloud or Generic Exchange are doing behind closed doors. You can't exactly sneak in and look at their accounting books to make sure they're not using their customers’ funds to buy yachts. Yeah, there have been cases. While users see clean interfaces and steady balances, the internal processes remain hidden. If we’re talking about centralized crypto exchanges, those balances aren’t even “real.” The coins are elsewhere, by the way. The balances are only “IOUs” on your behalf.\Some stablecoins provide an example of this. Tether, for instance, has faced ongoing scrutiny about whether its reserves fully back the tokens in circulation. Questions about transparency have persisted for years, with regulators and analysts asking for clearer disclosures. Without open verification, users rely on trust. If not all USDT tokens are backed and the public finds out, hell will break loose in the whole market.\The deceased FTX exchange is a darker case of a lack of transparency. Customers believed their funds were safe, but internal practices told a different story.Billions of dollars in customer assets were misused, leading to one of the largest failures in crypto history. The lack of visibility allowed risky behavior to continue until it became impossible to hide. That doesn’t happen in decentralized crypto networks because most of them have publicly available source codes, balances, and transactions.Regulatory and Political PressureCentralized entities are at the mercy of the legal rules imposed on them. That influence shapes how these systems handle security and user data, of course. Crypto exchanges often adjust policies to meet regulatory requirements, such as identity verification (KYC) and transaction monitoring.\Now, those measures can improve oversight but also create new data storage risks. Large databases of personal information become valuable targets for attackers. Besides, there have been cases where authorities have requested access to user data or restricted certain services. Security decisions may shift to align with legal demands rather than user protection.Political pressure can also lead to sudden changes. A platform might block regions, halt services, or alter features to meet new rules. Users have little influence over these decisions, yet they bear the consequences. The case of Tornado Cash proved that not only companies may be affected.An Escape in DecentralizationWe already have solutions at hand to avoid all these risks brought about by centralization, and we should use them. Decentralized ledgers and cryptocurrencies aren’t a fix-all, but they can improve our autonomy and ownership exponentially. \It also depends on what tools and networks we use, and the decentralization degree they offer. A lot of them still rely on their own powerful middlemen (miners or “validators”) to approve transactions, which may lead to censorship again. In that sense, Obyte is different.Built on an Acyclic Directed Graph (DAG) instead of a blockchain, Obyte’s design gets rid of miners, “validators,” or any other powerful middlemen. Users themselves add their own transactions without barriers or permission. They can also vote on-chain on key parameters of the network, and access features like smart contracts, self-sovereign identity, customized tokens, DeFi platforms, and more.\Finally, we can say that centralization keeps systems simple and familiar, but it also accumulates risk in ways that are easy to overlook. One weak point can ripple across an entire network. A single authority can become a gatekeeper, a target, and a blind spot. Spreading control doesn't remove every risk, yet it gives us more security and independence.\Featured Vector Image by macrovector / Freepik
