1. r\u00e9sz. A biz\u00e1nci t\u00e1bornokok feladata \u00e9s pletyk\u00e1k
\n<\/b>A t\u00f6rt\u00e9net alapja a \u201eBiz\u00e1nci t\u00e1bornokok feladata\u201d (Byzantine Fault Tolerance, BFT) nev\u0171 gondolatk\u00eds\u00e9rlet \u2014 amely bemutatja a rendszerek \u00e1llapot\u00e1nak szinkroniz\u00e1l\u00e1s\u00e1val kapcsolatos probl\u00e9m\u00e1t, amikor a kommunik\u00e1ci\u00f3 megb\u00edzhat\u00f3nak sz\u00e1m\u00edt, de a csom\u00f3pontok nem. Akiket \u00e9rdekel, itt vagy itt r\u00e9szletesebben is tanulm\u00e1nyozhatj\u00e1k a k\u00e9rd\u00e9st. <\/p>\n

A Hedera Hashgraph platform algoritmusai a biz\u00e1nci t\u00e1bornokok feladat\u00e1nak egy k\u00fcl\u00f6nleges eset\u00e9re, az aszinkron biz\u00e1nci t\u00e1bornokok feladat\u00e1ra (aBFT) alapoznak. 2016-ban el\u0151sz\u00f6r a matematikus Lemoyne Baird javasolt r\u00e1 megold\u00e1st, \u00e9s, hogy mondanival\u00f3j\u00e1t kar\u00f3ba h\u00fazza, azonnal be is jegyezte. <\/p>\n

A Hedera Hashgraph platform is characterized by the shared use and synchronization of digital data according to a consensus algorithm, physical decentralization of data storage nodes, and the absence of a single control center. However, the Hashgraph protocol (in this case, Hedera is the ecosystem, and Hashgraph is the protocol) does not relate to blockchains but represents a directed acyclic graph consisting of parallel sequences that start from one node and reach the final node through different paths. <\/p>\n

Roughly speaking, while a classic blockchain can be visually represented as a strict sequence of links (which is, in fact, its main property), Hashgraph visually resembles a bonsai with numerous branching. Since the number of simultaneous cycles is virtually unlimited, Hashgraph allows for an immense number of transactions to occur simultaneously (developers talk about 250,000 transactions per second, which exceeds Visa's capabilities fivefold, let alone the Bitcoin network), and the fee for a transaction is generally nonexistent.<\/p>\n

The next fundamental difference between Hashgraph and a classic blockchain is the gossip subprotocol (gossip protocol). Within the distributed ledger, each transaction does not mean the transfer of all data but rather the transfer of information about the information (Gossip about Gossip). A node informs two other arbitrary nodes about the transaction, each of which, in turn, broadcasts messages to two more until the number of informed nodes is sufficient to achieve consensus, which happens when a majority of nodes are informed (and it is due to this that the stated number of transactions per unit of time is reached). <\/p>\n

Part 2. A Blockchain Killer or Not
\n<\/b>Currently, Hedera Hashgraph is in the development process. Specifically, testing is underway for its own cryptocurrency supporting micropayments, distributed network file storage, and scenarios that allow the creation of smart contracts based on the Ethereum environment languages. <\/p>\n

A projekt k\u00f6r\u00fcli v\u00e9lem\u00e9nyek ritka polariz\u00e1ci\u00f3t mutatnak. Egyes forr\u00e1sok a Hashgraph-ot \"a blokkl\u00e1nc gyilkos\u00e1nak\" nevezik, m\u00edg m\u00e1sok helyt\u00e1ll\u00f3an megjegyzik, hogy nincsenek p\u00e9ld\u00e1k m\u0171k\u00f6d\u0151 decentraliz\u00e1lt alkalmaz\u00e1sokra a Hedera k\u00f6rnyezet\u00e9ben. Harmadik f\u00e9l pedig azt kifog\u00e1solja, hogy a platform alapja szabadalmaztatott, \u00e9s annak fejleszt\u00e9se egy fel\u00fcgyel\u0151 tan\u00e1cs ellen\u0151rz\u00e9se alatt \u00e1ll, amely a Fortune 500 lista sz\u00e1mos c\u00e9geinek k\u00e9pvisel\u0151ib\u0151l \u00e1ll (b\u00e1r az ut\u00f3bbi \u00e9ppen azt mutatja, hogy a projektnek val\u00f3di potenci\u00e1lja van, \u00e9s biztosan nem csal\u00e1s). Egy\u00e9bk\u00e9nt, egy ideje a projekt k\u00fcl\u00f6n\u00e1ll\u00f3 Hedera Hashgraph v\u00e1llalatt\u00e1 alakult, ami szint\u00e9n az fejleszt\u0151k sz\u00e1m\u00e1ra priorit\u00e1st jelent.<\/p>\n
