Tiknoolajiyada Blockchain^(Blockchain) waxay soo baxday iyada oo ka jawaabaysa burburkii dhowr hay'adood oo bangiyada ah 2008. Waxay soo jeedisay nidaam lacageed oo cusub oo loogu talagalay in laga saaro xakamaynta sahayda lacagta, iyada oo ku tiirsan kaliya nidaamka lacagta elektaroonigga ah ee asxaabta, oo si gaar ah loogu talagalay dijitalka. boqortooyada. Nidaamkan lacagta online-ka ah ayaa la aaminsanaa in uu yahay nidaam lacageed oo wanaagsan ilaa qaar ka mid ah ay bilaabeen inay ka hadlaan Hashgraph .

Waa maxay Hashgraph

Hashgraph waxaa la sheegay inuu yahay nidaam aad u adag. Algorithm-ka la isku raacsan yahay wuxuu bixiyaa madal cusub oo la isku raacsan yahay. Qaar ka mid ah sifooyinka sida caadiga ah loo isticmaalo tixraaca ama lagu qeexo Blockchain waa la qaybiyaa, daah-furan, heshiis ku salaysan, macaamil ganacsi iyo dabacsanaan. Hashgraph waxay xambaarsan tahay sifooyinkan oo dhan. Si kastaba ha ahaatee, waa qaab-dhismeedka xogta iyo algorithm la isku raacsan yahay oo aad uga dhakhso badan, caddaalad ah, oo ka ammaan badan blockchain. Waxaa lagu tilmaamay inay tahay mustaqbalka tignoolajiyada ledgerka la qaybiyay. Waxay isticmaashaa laba farsamooyin gaar ah si loo gaaro heshiis degdeg ah, cadaalad ah oo sugan.

1. Xanta xanta
2. Codeynta Virtual

Xanta ku saabsan xanta^{(Gossip about Gossip)} asal ahaan waxay la macno tahay in lagu lifaaqo xog yar oo dheeri ah Xantan^(Gossip) , kuwaas oo ah laba xashiish oo ay ku jiraan labadii qof ee ugu dambeeyay ee lala hadlo. Isticmaalka macluumaadkan, Hashgraph waa la dhisi karaa oo si joogto ah ayaa loo cusboonaysiin karaa marka macluumaad dheeraad ah la xamanayo, oo dusheeda ah.

Marka Hashgraph- ku diyaar yahay, way fududahay in la ogaado waxa noodu u codayn doono, maadaama aan ka warqabno macluumaadka uu nood kastaa haysto iyo goorta ay garanayaan. Xogtan ayaa markaa loo isticmaali karaa qayb ka mid ah algorithmamka codaynta iyo in la helo macaamilada si degdeg ah u gaadhay heshiis la isla qaatay.

Hashgraph vs Blockchain

Tignoolajiyada Blockchain waa buug dijitaal ah oo aan la dumin karin oo macaamil dhaqaale ah. Si kastaba ha ahaatee, waxaa la qorsheeyey in la duubo ma aha oo kaliya macaamil ganacsiyeedka laakiin wax kasta oo qiimo leh. Xogta^{(Information)} lagu hayo blockchain waxay u jirtaa sidii la wadaagay oo si joogto ah waa loo heshiiyaa/la cusboonaysiiyaa. Tani waxay hubinaysaa in diiwaanada/xogta ay hayso ay isku mid yihiin shabakadaha oo aan lagu kaydin meel gaar ah. Sidan oo kale, blockchain laguma xakamayn karo hal qayb. Marka labaad^(Second) , ma laha hal dhibic oo guul darro ah.

Hashgraph , dhanka kale, waxay sheeganeysaa inay taageerto qaab dhismeed xogeed heersare ah oo awood u leh inuu xalliyo dhibaatooyin badan oo bulshada Blockchain ay la halgamaysay in muddo ah sida, hababka la isku raacsan yahay.

Ilaa hadda, tignoolajiyada la isku raacsan yahay ayaa loo kala saaray laba qaybood middood:

1. Shabakadaha dadweynaha (ay ku jiraan Bitcoin iyo Ethereum )
2. Gaar ah^(Private) (xalka ku tiirsan algorithms is-afgarad ku salaysan hoggaamiyaha)

Shabakadaha dadwaynaha ayaa qaali ku ah socodsiinta waxayna leeyihiin caqabado shaqo oo ka yimaada Caddaynta Shaqada^{(Proof of Work)} (ku heshiiyaan nidaamka ay wax u kala iibsan karaan. Tani waxay hubinaysaa in sahayda lacagta ay joogto tahay oo qofna ma khiyaameeyo). Tani waxay hoos u dhigeysaa tirada codsiyada halka tignoolajiyada noocaas ah si dhab ah loogu shaqeyn karo.

Shabakadaha gaarka ah, si ka duwan, shabakadaha dadwaynaha ayaa xaddidaya isticmaalka ka qaybgalayaasha la yaqaan iyo kuwa la aamini karo. Habkani wuxuu hoos u dhigayaa qiimaha wuxuuna hagaajinayaa waxqabadka si weyn, iyadoo algorithms awood u leh inay gaaraan 1000 xawaalad ilbiriqsi kasta marka la barbar dhigo toddobada Bitcoin . Taasi waxay tidhi, daldaloolada qaabka jaangooyooyinka amniga dabacsan ayaa shabakadahan ka dhigaya bartilmaameedyo suurtagal ah weerarrada DDoS^{(DDoS attacks)} .

Swirld's 'Hashgraph algorithm wuxuu ka gudbaa cilladahaan maadaama uusan u baahnayn Caddeyn ^(Proof)Shaqo^(Work) iyo Hogaamiye midna . ^(Leader)Intaa waxaa dheer, waxay ballan qaadaysaa inay bixiso qiimo jaban iyo waxqabad wanaagsan oo aan lahayn hal dhibic oo guuldarro ah.

Isku dhafkan waa kan ka dhigaya Hashgraph qalab, oo mudan in la isku dayo.

Faa'iidooyinka kale ee HashGraph ka bixiso Blockchain

Algorithm is-afgarad cusub oo ku salaysan tignoolajiyada sare ee ledgerka la qaybiyey. Tani waxay meesha ka saaraysaa shuruudaha xisaabinta ballaaran iyo isticmaalka tamarta aan joogtada ahayn sida kuwa Bitcoin iyo Ethereum .

Sida hore loo sheegay, Bitcoin waxay ku xaddidan tahay 7 macaamil ganacsi ilbiriqsi kasta. Dhanka kale, Hashgraph waa 50,000 jeer ^(Times) Dhakhso^(Faster) : xaddidan oo kaliya bandwidth - 250,000+ macaamil ganacsi^{(Transactions Per Second)} ilbiriqsi kasta ( Pre-Sharding )

Ka cadaalad badan

Dunida blockchain, macdan qodayaashu waxay dooran karaan amarka ay macaamiladu ku dhacaan block, waxay dib u dhigi karaan amarrada iyaga oo ku dhejinaya blocks mustaqbalka, xitaa waxay joojiyaan gabi ahaanba inay galaan nidaamka. Shaabadaynta^(Consensus) wakhtiga la isku raacsan yahay ee la heli karo Hashgraph waxay bixisaa xal dhibaatadan. Waxay ka hortagtaa shakhsiga inuu saameeyo nidaamka la isku raacsan yahay ee wax kala iibsiga isagoo diidaya nooc kasta oo wax-is-daba-marin ah oo ku saabsan nidaamka macaamilka.

Dulqaadka Ciladda Byzantine^{(Byzantine Fault Tolerant)} Asynchronous

Si ka duwan nidaamyada kale, Hashgraph waxaa la caddeeyey inuu yahay Byzantine si buuxda isku mid ah . Tani waxay la macno tahay in aanay wax malo ah ka samaynayn sida dhakhsaha leh ee farriimaha loogu gudbiyo internetka. Awooddani waxay ka dhigaysaa mid u adkaysata weerarrada DDoS , botnets, iyo firewalls. Bitcoin ma aha Byzantine . Xitaa byzantine ma aha hoos malo xun. Bitcoin dhexdeeda , marna ma jirto waqti aad ku ogaanayso inaad leedahay heshiis.

100% hufan

Ma jiro baloog macdan qodan ah oo weligii duugoobay. Halka^(Whereas) blockchain-ka, wax kala iibsiga lagu rido weel (blocks) ka samaysan hal silsilad dheer. Haddii laba nin oo macdan qodayaal ahi ay isku mar abuurmaan laba baloog, bulshadu aakhirka waxay dooranaysaa mid ka kalena way iska tuuri doontaa, taasina waxay keentaa in dedaallo la’aan. Hashgraph , weel^(Hashgraph) kasta waa la isticmaalayaa midna lama tuuro.

Marka, in kasta oo Hashgraph ay u muuqato inay tahay tignoolajiyad ka sarraysa Blockchain, haddana waa in la xusuustaa in arrimuhu si degdeg ah u dhaqaaqi karaan. Taasi waa, marka aad bilowdo inaad wax ka barato wax cusub, wax kale ayaa beddelaya ka hor intaadan si guul leh ula qabsan.

What is Hashgraph? How is it different from Blockchain?

Blockchain technology emerged in reѕponse to the collapse of several banking institutions in 2008. It proposed a new monetary system intended to take away the control of the money supply, relying solely on a peer-to-peer electronic cash system, designed ѕpecifically for the digital realm. This onlіne currency system was believed to be a better monetary system until some started talking about Hashgraph.

What is Hashgraph

Hashgraph is said to be a more robust system. Its consensus algorithm provides a new platform for distributed consensus. Some of the attributes commonly used to refer or describe Blockchain are distributed, transparent, consensus-based, transactional and flexible. Hashgraph bears all these features. However, it is a data structure and consensus algorithm that is much faster, fairer, and more secure than blockchain. It is described as the future of distributed ledger technology. It uses two special techniques to achieve fast, fair and secure consensus.

1. Gossip about Gossip
2. Virtual Voting

Gossip about Gossip basically means attaching a small additional amount of information to this Gossip, which are two hashes containing the last two people talked to. Using this information, a Hashgraph can be built and regularly updated when more information is gossiped, on each node.

Once the Hashgraph is ready, it is easy to know what a node would vote, since we are aware of information that each node has and when they knew it. This data can thus be used as an input to the voting algorithm and to find which transactions have reached consensus quickly.

Hashgraph vs Blockchain

Blockchain technology is an incorruptible digital ledger of economic transactions. However, it can be programmed to record not just financial transactions but virtually everything of value. Information held on a blockchain exists as shared and is continually reconciled/updated. This ensures the records/data it holds are identical across the network and not stored in any individual location. As such, the blockchain cannot be controlled by any single entity. Second, it has no single point of failure.

Hashgraph, on the other hand, claims to support a superior data structure capable of solving many of the problems that the Blockchain community has been struggling with for some time like, consensus mechanisms.

Until now, consensus technologies were classified into one of two categories:

1. Public networks (includes Bitcoin and Ethereum)
2. Private (solutions relying on Leader-based consensus algorithms)

Public networks are expensive to run and have performance constraints resulting from Proof of Work (agreeing to the order in which transaction can occur. This ensures money supply is constant and no one cheats). This narrows down the number of applications where such technologies can be practically employed.

Private networks, unlike, public networks restrict usage to known and trusted participants. This approach brings down the cost and improves performance dramatically, with algorithms capable of achieving 1000 transactions per second compared to seven for Bitcoin. That said, loopholes in the form of relaxed security standards make these networks potential targets to DDoS attacks.

Swirld’s’ Hashgraph algorithm overcomes these shortcomings as it requires neither Proof of Work nor a Leader. Moreover, it promises to deliver low-cost and good performance with no single point of failure.

It is this combination that makes Hashgraph a tool, worth trying.

Other advantages HashGraph offers over Blockchain

A new consensus algorithm based on superior distributed ledger technology. This eliminates the requirement for massive computation and unsustainable energy consumption like those of Bitcoin and Ethereum.

As mentioned earlier, Bitcoin is limited to 7 transactions per second. On the other hand, Hashgraph is 50,000 Times Faster: limited only by bandwidth — 250,000+ Transactions Per Second (Pre-Sharding)

Fairer

In the blockchain world, a miner can choose the order for which transactions occur in a block, can delay orders by placing them in future blocks, even stop them entirely from entering the system. Consensus time stamping available with Hashgraph offers a solution to this problem. It prevents an individual from affecting the consensus order of transactions by denying any sort of manipulation of the order of the transactions.

Asynchronous Byzantine Fault Tolerant

Unlike the other systems, Hashgraph is proven to be fully asynchronous Byzantine. This means it makes no assumptions about how fast messages are passed over the internet. This capability makes it resilient against DDoS attacks, botnets, and firewalls. Bitcoin is not Byzantine. It’s not even byzantine under bad assumptions. In Bitcoin, there is never a moment in time where you know that you have consensus.

100% Efficient

No mined block ever becomes stale. Whereas in the blockchain, transactions are put into containers (blocks) that form a single, long chain. If two miners create two blocks at the same time, the community will eventually select one and discard the other, resulting in wastage of efforts. In Hashgraph, every container is used and none are discarded.

So, although Hashgraph appears to be a superior technology to Blockchain it should be remembered things can just move a little too fast. That is, once you begin to learn about something new, something else replaces it before you can successfully adapt.
