Come creare una transazione

Ci sonopiù riferimenti online chefornisconomaterialeper comprenderei passaggi coinvoltiin questo. Puoi controllare questo o quello . Alcunielementi sonoforniti anchein quest'altra domanda

Fondamentalmentei passaggi sono

1. ottieni dipendenze
   • hash ramo: /chains/main/blocks/head/hash
   • counter: /chains/main/blocks/head/context/contracts/<source_pkh>/counter
   • hash delprotocollo: /protocols
2. operazione diforgiatura (/chains/main/blocks/head/helpers/forge/operations) Notabene se èfacile replicare questa logica al difuori del clientnativo
3. byte di segno (tezos-client sign bytes)
4. operazionepreapply (/chains/main/blocks/head/helpers/preapply/operations/)
5. decodifica lafirmain formatoesadecimale
6. inject operazione (/inject/operation)

There are multiple references online which provide material to understand the steps involved in this. You can check this or that. Some elements are also provided in this other question

Basically the steps are

1. get dependencies
   • branch hash: /chains/main/blocks/head/hash
   • counter: /chains/main/blocks/head/context/contracts/<source_pkh>/counter
   • protocol hash: /protocols
2. forge operation (/chains/main/blocks/head/helpers/forge/operations) Note sure if it's easy to replicate this logic outside from the native client though
3. sign bytes (tezos-client sign bytes)
4. preapply operation (/chains/main/blocks/head/helpers/preapply/operations/)
5. decode signature to hexadecimal format
6. inject operation (/inject/operation)

helpers/scripts/run_operation è utileper simulare un'operazione senzafirmarla (èpossibile utilizzare zerobyteper lafirma),alfine di stimarei requisiti digase stoccaggio.Vedrai tezos-client -l cheimpostagas_limite storage_limit ai valorimassimi qui,quindi utilizzail risultatoperimpostareilgas_limite lo storage_limiteffettivi (soggetto al limitemassimo di storage accettabile dell'utente,chiamato "-burn-cap ").

Per sapere come l'operazione è codificatain binario,puoi vedere tezos-client describe unsigned operation.

helpers/scripts/run_operation is useful to simulate an operation without signing it (you may use zero bytes for the signature), in order to estimate the gas and storage requirements. You will see tezos-client -l setting gas_limit and storage_limit to the maximum values here, and then using the result to set the actual gas_limit and storage_limit (subject to the user's maximum acceptable storage_limit, called "--burn-cap").

To learn how the operation is encoded in binary, you can see tezos-client describe unsigned operation.

Ilmodopiù semplice sarebbe controllare come ades.eztzimplementai trasferimenti .

Quindiguarda come vengonoforgiate le operazioni ditrasferimento qui .

Einfine come vieneiniettata l'operazione contraffatta qui .

A quantopare,sembra che forge dieztz siaeseguitoin remoto da /helpers/forge/operations.

Easiest would be checking out how e.g. eztz implements transfers.

Then see how the transfer operations is forged here.

And finally how the forged operation is injected here.

By the looks of it, seems like eztz's forge is done remotely by /helpers/forge/operations.
