NBER Study Reveals Bitcoin Is Over Concentrated And Vulnerable To A 51% Attack

A new study reveals that Bitcoin is concentrated in the hands of a few whales.The research goes on to reveal that Bitcoin miners are heavily concentrated and leave the network susceptible to a 51% attack. The largest BTC whales include MicroStrategy, Satoshi Nakamoto, Micree Zhan, and the Winklevoss twins.

Jedným z predajných miest Bitcoin is the extent of its decentralization over traditional financial systems. A recent study by the National Bureau of Economic Research reveals that the network might not be as decentralized as we think.

Niekoľko rúk, veľa BTC

An in-depth study by the National Bureau of Economic Research, (NBER) has revealed that the bulk of Bitcoins is owned by a few individuals. The research team utilized a methodology that involved splitting addresses between intermediaries and individuals, which generated interesting results despite the difficulty of the undertaking.

Štúdia odhalila, že 10,000 6,000,000 peňaženiek ovláda viac ako 1,000 3,000,000 XNUMX BTC, čo je tretina všetkej kryptomeny v obehu. Pri ďalšom skúmaní NBER zistil, že popredných XNUMX XNUMX investorov vlastní okolo XNUMX XNUMX XNUMX BTC, pričom metriky sa vysoko koncentrujú ďalej v rebríčku. 

"Toto meranie koncentrácie je s najväčšou pravdepodobnosťou podhodnotené, pretože nemôžeme vylúčiť, že niektoré z najväčších adries sú kontrolované rovnakým subjektom," povedali výskumníci. “Our results suggest that despite the significant attention that Bitcoin has received over the years, the Bitcoin ecosystem is still dominated by large and concentrated players, be it large miners, Bitcoin holders or exchanges.”

Trend koncentrácie možno objaviť aj medzi ťažiarmi kryptomien, kde vedúcich 10 % ťažiarov predstavovalo 90 % generovania aktív, zatiaľ čo len zlomok bol zodpovedný za 50 %. Napriek zdanlivo decentralizovanej povahe siete, štúdia NBER pokračuje v nakreslení iného obrazu.

Nevýhodou veľkej koncentrácie baníkov podľa štúdie je náchylnosť na 51% napadnutie siete. K tomuto druhu útoku dochádza, keď útočník získa väčšinovú kontrolu nad hashovacou silou blockchainu.

najväčší Bitcoin Whales And Miners

Although it’s hard to tell who the largest holders of Bitcoin are, some entities stand out from the pack as the biggest whales. For organizations, MicroStrategy is the largest entity with an odhadovaných 111,042 6 BTC, ktoré majú hodnotu viac ako XNUMX miliárd dolárov a nevykazujú žiadne známky spomalenia akvizícií.

Bitcoin’s founder, Satoshi Nakamoto is said to have over 1 million BTC in his possession which would make him the largest whale. Other noteworthy individuals include the Winklevoss brothers, Barry Silbert, Tim Draper, Michael Novogratz, and Micree Zhan, the owner of Bitmain.

Prior to China’s cryptocurrency crackdown, the country accounted for over 50% of Bitcoin’s hash rate but with the tide turning, America now has the highest concentration of Bitcoin baníci. Na druhom a treťom mieste sú Kazachstan a Rusko.
