Anei Bitcoin Me Nga Kohakore o Ethereum, E ai ki tenei Whakatewhatewha a Pentagon

I whakairihia e te kamupene haumaru Trail of Bits he pūrongo on potential vulnerabilities that can allegedly affect the Bitcoin (BTC) and Ethereum (ETH) blockchain. Called “Are Blockchains Decentralized?”, the report was funded by the U.S. Department of Defense via its Defense Advanced Research Projects Agency (DARPA).

The report is focused on Bitcoin and Ethereum but approaches other blockchain-based platforms using Proof-of-Work (PoW) and Proof-of-Stake (PoS) and Byzantine Fault Tolerant consensus protocols in general.

I whakatauhia e te whakatewhatewha he "kaha" nga waahanga cryptographic o enei whatunga, me nga whakaraeraetanga kerēme kei roto i te whakatinanatanga poraka, me nga kawa whakaae. I etahi atu kupu, e whakapono ana te umanga haumarutanga ka taea te whakamahi poraka, engari he kaha te tuhinga tuhi e tautoko ana ia ratou.

Trail of Bits arrived at the following conclusions during their investigation: Bitcoin, Ethereum, and other blockchains have a “privileged set of entities” with the power to change their transactions, unencrypted traffic, nodes running old “vulnerable” software, and others.

I te nuinga o te korero, e kii ana te ripoata kaore i te whakahekehia nga whatunga poraka, a he whakaraerae ratou ki te raupapa o nga waahi whakaeke me te raruraru mai i nga kaiwhakaari o waho. Ina koa, i tohu ratou ko nga whatunga poraka o naianei kaore he "utu Sybil" te tikanga ka taea "ngawari" te whakaeke:

For a blockchain to be optimally distributed, there must be a so-called Sybil cost. There is currently no known way to implement Sybil costs in a permissionless blockchain like Bitcoin or Ethereum without employing a centralized trusted third party (TTP)Until a mechanism for enforcing Sybil costs without a TTP is discovered, it will be almost impossible for permissionless blockchains to achieve satisfactory decentralization.

Kaore he korero, kua paopao te hapori crypto i nga whakatau o enei kitenga. Ko nga moni crypto nui e rua na te putea maakete BTC me te ETH i hangaia i runga i te whakaaro ki te hanga i nga punaha whakaheke, kore pono, maamaa me te tuwhera. Ko nga wero o te ripoata e kii ana kua rahua ratou i roto i tera ahuatanga.

He Bitcoin And Ethereum Truly Decentralized?

He tino tautohetohe te ripoata na runga i ana kitenga, i te tika o ana whakatau, a na te mea i whiwhi putea mai i te US Pentagon, na nga rangatira o te kawanatanga o tenei whenua i whakaputa korero kino ki te umanga crypto me nga moni crypto.

The CTO and Co-founder at Swan Bitcoin Yan Pritzker and its Editor-in-Chief Tomer Strolight meka tirohia the investigation and arrived at discrepancies. Their arguments were in support of Bitcoin that “most blockchains are centralized to varying degrees (…)”.

The report from Pritzker and Strolight studies Trail of Bits claims one by one. First, they said Bitcoin lacks a “privileged set of entities” capable of changing its code, as it’s the user running the nodes that decide which software code they run. They add:

Even if we focus on the most popular Bitcoin kiritaki, bitcoin-core, the claim that four people control the source code is also FALSE (…). Many other blockchains employ a forced-upgrade mechanism such as Ethereum’s difficulty bombs. In those cases, we find the claim to be largely TRUE (…).

I tua atu, i whakanuia e Pritzker me Strolight te rereketanga i waenga i nga puna keri me nga kaikeri ki te tohu kaore e taea e te hunga o mua te whakararu i te whatunga, e ai ki te ripoata a DARPA. I runga i te utu whakaeke a Sybil a BTC, e kii ana te purongo i nga korero e whai ake nei me pehea te hanga o te cryptocurrency me te kaupapa o te aukati i tenei vector whakaeke ki tana whatunga:

The invention of Nakamoto Consensus (i.e. Bitcoin’s reliance on proof of work for source of truth) was literally designed to prevent Sybil attacks. Satoshi wanted any participant to be able to add a block, but choosing one user at random would be open to individuals pretending to be many users. But work cannot be faked (…).

I te wa e tuhi ana, ko te utu o te BTC e tuhi ana i te 3% i roto i nga haora 24 kua pahure ake nei me te hokohoko i te $20,000.
