ʻAʻole maopopo iaʻu ke kumu i hōʻike ʻia ai nā ʻike āpau e pili ana iā Hedera Hashgraph ma ke ʻano huikau, inā paha he hopena kēia o ke kulekele ʻike o nā mea hoʻomohala a i ʻole he pōʻino. Akā i kekahi hihia, ua paʻakikī loa ke kākau ʻana i kahi kikokikona pili e pili ana iā Hedera Hashgraph. I kēlā me kēia manawa me he mea lā ʻo ia, ua hoʻomaopopo hope wau i nā mea a pau, ʻaneʻane ʻike koke ʻia a ʻike hou ʻia he hoʻopunipuni hohonu kēia. I ka hopena, me he mea lā ua puka mai kekahi mea koʻikoʻi, akā naʻe - heluhelu pono, ʻaʻole i pau ka pilikia o ka hemo ʻana o kou lolo.
Mahele 1. ʻO ka hana a nā Generala Byzantine a me ka haʻihaʻi
ʻO ka puʻuwai o kēia moʻolelo ka mea i kapa ʻia ʻo Byzantine Fault Tolerance (BTF), kahi hoʻokolohua noʻonoʻo i hoʻolālā ʻia e hōʻike i ka pilikia o ka hoʻonohonoho ʻana i ke kūlana o nā ʻōnaehana i ka hihia kahi i manaʻo ʻia ai nā kamaʻilio hilinaʻi, akā ʻaʻole pono nā nodes. Hiki i ka poʻe hoihoi ke aʻo i ka pilikia ma aneʻi a i ʻole ma ʻaneʻi i nā kikoʻī hou aku.
Kūkulu ʻia nā algorithms o ka platform Hedera Hashgraph ma kahi hihia kūikawā o Byzantine Fault Tolerance, ka Asynchronous Byzantine General Task, a i ʻole aBFT. I ka makahiki 2016, ua hāʻawi mua ka mea makemakika ʻo Lemon Baird i kahi hoʻonā no ia, a mai lilo ʻoe i naʻaupō, hoʻopaʻa koke iā ia.
Hōʻike ʻia ke kahua ʻo Hedera Hashgraph e ka kaʻana like a me ka hoʻonohonoho ʻana i nā ʻikepili kikohoʻe e like me ka algorithm consensus, ka decentralization kino o nā nodes mālama ʻikepili a me ka nele o kahi kikowaena hoʻokahi. Eia naʻe, ʻo ka protocol Hashgraph (ma kēia hihia, ʻo Hedera ka eco-environment, ʻo Hashgraph ka protocol) ʻaʻole ia i nā blockchains, akā he digraph me ka ʻole o nā kaʻina sequential a me nā kaʻina like e hoʻomaka ana ma kahi node a hiki i ka node hope. ma na ano like ole.
ʻO ka ʻōlelo koʻikoʻi, inā hiki ke ʻike ʻia kahi blockchain maʻamau e like me ke ʻano o nā loulou (ʻo ia hoʻi, ʻo ia kāna waiwai nui), a laila ʻike ʻia ʻo Hashgraph i kahi bonsai me ka nui o nā lālā. No ka mea ʻaʻole palena ʻole ka helu o nā pōʻai like ʻole, ua ʻae ʻo Hashgraph i ka nui o nā hana e hana ʻia i ka manawa like (ʻōlelo nā mea hoʻomohala 250 tausani i kēlā me kēia kekona, ʻo ia ka ʻelima mau mana o Visa, ʻaʻole e haʻi i ka pūnaewele Bitcoin). a ʻaʻohe kumu kūʻai maʻamau .
ʻO ka ʻokoʻa hou aʻe ma waena o Hashgraph a me ka blockchain maʻamau ka sub-protocol gossip. I loko o kahi papa kuhikuhi, ʻaʻole kēlā me kēia kālepa i ka hoʻololi ʻana i nā ʻikepili āpau, akā ʻo ka ʻike wale nō e pili ana i ka ʻike (Gossip about Gossip). Hoʻomaopopo ka node i ʻelua mau node ʻokoʻa ʻē aʻe e pili ana i ke kālepa, ʻo kēlā me kēia, e hoʻolaha i nā memo i nā ʻelua ʻē aʻe a hiki i ka manawa e lawa ai ka helu o nā node i hōʻike ʻia e hoʻokō i ka ʻae ʻana, a ke hana nei kēia i ka wā e ʻike ʻia ai ka hapa nui o nā node ( a ma muli o ia mea i loaʻa ai ka helu o nā hana i kēlā me kēia manawa).
Mahele 2. Blockchain pepehi kanaka a i ole
Ke kūkulu ʻia nei ʻo Hedera Hashgraph i kēia manawa. Ma keʻano kūikawā, ke hoʻāʻo nei mākou i kā mākou cryptocurrency ponoʻī me ke kākoʻo no nā micropayments, ka mālama ʻana i ka ʻoihana pūnaewele o nā faila a me nā palapala e hiki ai iā mākou ke hana i nā ʻaelike akamai e pili ana i nā ʻōlelo o ke kaiapuni Ethereum.
Kakaʻikahi ka polarized nā manaʻo ma kēia papahana. Kekahi mau kumu bluntly kapa Hashgraph he "blockchain killer", 'ē aʻe pololei kuhikuhi 'aʻohe laʻana o ka hana decentralized noi i loko o ka Hedera kaiapuni, 'ē aʻe i huikau e ka mea i ke kumu o ka anuu ua patented, a me kona ulu ana ma lalo o ka ka mana o ka papa hoʻomalu, e komo pū ana nā ʻelele o kekahi mau hui mai ka papa inoa ʻo Fortune 500 (ʻoiai ʻo ia ka manaʻo he mana maoli ka papahana a ʻaʻole ia he scam). Ma ke ala, i kekahi manawa i hala aku nei ua wili ʻia ka papahana i kahi hui ʻokoʻa, ʻo Hedera Hashgraph, kahi e hōʻike ai i kāna mea nui no nā mea hoʻomohala.
ʻO nā mea hoʻomohala, me ka nui ʻole o ka haunaele, ua hōʻiliʻili mua i $ 18 miliona no nā pono hana ma ke kūʻai ʻana i nā hōʻailona pani a, ma hope o kekahi manawa, ʻo $ 100. ʻAʻohe mea kikoʻī e pili ana i ka ICO i hōʻike pū ʻia, a ma ke ʻano nui, ʻaʻole hiki ke hoʻomaopopo ʻia ka palapala alanui Hedera Hashgraph. ʻAʻole ia e pale i ka ʻoihana mai ka hana ʻana i nā hana ikaika e pili ana i ka hoʻolaha ʻana i kēia algorithm consensus, ke hana ikaika nei ka ʻoihana i ka hoʻokumu ʻana i nā kaiāulu ʻoihana like ʻole - mai nā mea papahana a i nā loio, ua mālama mua nā ʻelele o ka papahana ma mua o 80 mau hālāwai me nā kamaʻāina hoihoi a puni ka honua, a hiki i Rusia - i ka lā Malaki 6, ua mālama ʻia kahi hālāwai ma Moscow me ka Pelekikena o Hedera Hashgraph Tom Trowbridge, e like me kā lākou e ʻōlelo nei, ua hui pū i nā ʻelele he nui o kā mākou IT a me nā pōʻai kālā.
Ua ʻōlelo ʻo Mr. Trowbridge, i ka wā e hiki mai ana ma kahi o 40 mau noi decentralized e pili ana iā Hedera Hashgraph e manaʻo ʻia, a ma ke ʻano he 100 o lākou e hana nei, no laila i ka wā e hiki mai ana e loaʻa i nā kānaka āpau ka manawa e ʻike ai i ka hana ʻana o kēia ʻoihana. .
Hōʻuluʻulu
Ma keʻano laulā, hiki ke ʻōlelo ʻia kekahi mau mea me ka maopopo. ʻO ka mea mua, he mea ʻole ka papahana a ua hoʻāla mua i ka hoihoi nui mai nā ʻelele o nā hui nui. ʻO ka lua, no ka non-specialist ia i frankly incomprehensible, ka mea, apparently, wehewehe i ka nele o kaʻikepili e pili ana iā ia i loko o ka lehulehu (a no hoi, e hookolokolo ana ma ka wikiō me Mr. ʻōlelo a pau). ʻO ke kolu, ʻaʻole paha e lilo ia i "Bitcoin killer" a i ʻole kekahi mea like ʻole, akā ʻo kāna mau mea maikaʻi i ʻōlelo ʻia he mea nui e hahai pono i ka papahana.
Eia kekahi, aia nā lono e hele koke ana nā mea hoʻonohonoho i ka tranche o nā hoʻopukapuka e hiki mai ana, hiki ke kūpono ke komo i loko.
