TEEs na Blockchains: Njirimara ndị ọzọ

Blockchains na TEEs nwere ike dị iche iche:

• Blockchains na-ekwe nkwa nnweta, nkwụsi ike nke steeti, ma kwe ka ọha na eze nyochaa steeti ahụ dum - mana ha nwere ikike ngụkọta oge pere mpe.
• TEEs nwere ike ịrụ ọrụ mgbagwoju anya na nzuzo - mana enweghị nkwụsi ike nke ala.

Ha niile jikọrọ aka mee ka e nwee usoro dị ike nke na-echebe ihe nzuzo.

Ntanetị Nzuzo: Nzuzo nke TEE kwadoro

Secret Network na-eji teknụzụ TEE (ọkachasị Intel SGX) iji mee ngụkọta na ntinye, mmepụta, na steeti ezoro ezo.

Onye ọ bụla na-agba ọsọ Intel SGX ibe. A na-ejikọta nkwekọrịta na nhazi ọkwa:

• A na-edozi azụmahịa n'ime oghere ndị nwere nchebe.
• A na-edozi data naanị n'ime TEE.

This is different from Zcash, which uses zero-knowledge proofs for privacy. In Zcash, shielded transactions are broadcast and validated publicly with no additional data revealed to the network. Zcash Shielded Assets follow the same principle.

Maka nkọwa zuru ezu banyere etu esi etinye TEEs na Secret Network, gụọ ọmarịcha edemede a site n'aka @l_woetzel: https://carter-woetzel.medium.com/secret-network-tees-lets-talk-fud-vulnerability-33ca94b6df38

Otú Ntaneti Nzuzo Si Echebe Mkpịsị Ụzọ na Ọnọdụ

• A na-echekwa mkpụrụ nzuzo nzuzo nke netwọk ahụ n'ime TEE nke onye nyocha ọ bụla.
• Nkwekọrịta na-eji igodo ezoro ezo pụrụ iche.
• Secret contracts run on the Cosmos SDK compute module but support encrypted inputs/outputs and state.

Ịkpọchi data

Ebe ọ bụ na enklave enweghị steeti, a ga-echekwa data mgbe ụfọdụ n'èzí na ebe nchekwa a na-atụkwasịghị obi.

Data Sealing encrypts data inside the enclave using a key derived from the CPU. The encrypted block can only be unsealed on the same system.

Oasis Network

Oasis Network na-ejikwa TEEs site na nzuzo ya ParaTime (dịka Sapphire na Cipher).

A na-abanye data ezoro ezo na TEE yana nkwekọrịta smart. A na - agbagha ya, hazie ya, ma degharịa ya tupu ịhapụ ogige ahụ.

TEEs na Proof-of-Stake Networks

Ọtụtụ Proof-of-Stake blockchains (gụnyere Nzuzo na Oasis) jiri Tendermint dị ka usoro nkwekọrịta ha.
