github.com/hyperion-hyn/go-ethereum@v2.4.0+incompatible/docs/Privacy/Tessera/Usage/Interface & API.md (about) 1 ## Interface Details 2 3 All interfaces can be set to run over HTTP, GRPC or HTTP-over-Unix-Sockets. 4 5 ### gRPC (for inter-node communication) 6 7 We currently have an implementation of gRPC for peer node communication as experiment API. This is not enabled on Quorum yet, but between Tessera nodes they can be enabled by adding in a couple of properties in the configuration file as child elements of `serverConfig`. 8 9 - `grpcPort` - when this value is specified, Tessera node will start a gRPC server listening on this port. The normal `port` value would still be used for starting REST server. 10 11 - `communicationType` - possible values are `REST`, `GRPC`. Default value is `REST`. 12 13 Please note that communication between Quorum and Tessera are still via unix socket. This communication flag provides additional options for Tessera peer-to-peer communication. If gRPC is the option specified, please ensure the peers urls are provided with the appropriate ports. 14 15 --- 16 17 ### Tessera to Tessera - Public API 18 19 Tessera nodes communicate with each other for: 20 21 - Node/network discovery 22 - Sending/Receiving encrypted payloads 23 24 The following endpoints are advertised on this interface: 25 26 * `/version` 27 * `/upcheck` 28 * `/push` 29 * `/resend` 30 * `/partyinfo` 31 * `/partyinfo/validate` 32 33 ### Third Party - Public API 34 35 Tessera nodes communicate with third parties for: 36 37 - storing encrypted payloads for external applications 38 39 The following endpoints are advertised on this interface: 40 41 * `/version` 42 * `/upcheck` 43 * `/storeraw` 44 45 ### Quorum to Tessera - Private API 46 47 Quorum uses this API to: 48 - Check if the local Tessera node is running 49 - Send and receive details of private transactions 50 51 The following endpoints are advertised on this interface: 52 - `/version` 53 - `/upcheck` 54 - `/sendraw` 55 - `/send` 56 - `/receiveraw` 57 - `/receive` 58 - `/sendsignedtx` 59 60 ### Admin API 61 62 Admins should use this API to: 63 - Access information about the Tessera node 64 - Make changes to the configuration of the Tessera node 65 66 The following endpoints are advertised on this API: 67 - `/peers` - Add to, and retrieve from, the Tessera node's peers list 68 - `/keypairs` - Retrieve all public keys or search for a particular public key in use by the Tessera node 69 70 ## API Details 71 72 **`version`** - _Get Tessera version_ 73 74 - Returns the version of Tessera that is running. 75 76 **`upcheck`** - _Check Tessera node is running_ 77 78 - Returns the text "I'm up!" 79 80 **`push`** - _Push transactions between nodes_ 81 82 - Persist encrypted payload received from another node. 83 84 **`resend`** - _Resend transaction_ 85 86 - Resend all transactions for given key or given hash/recipient. 87 88 **`partyinfo`** - _Retrieve details of known nodes_ 89 90 - GET: Request public keys/url of all known peer nodes. 91 - POST: accepts a stream that contains the caller node's network information, and returns a merged copy with the callee node's network information 92 93 **`partyinfo/validate`** - _Validates a node possesses a key_ 94 95 - Will request a node to decrypt a transaction in order to prove that it has access to the private part of its advertised public key. 96 97 **`sendraw`** - _Send transaction bytestring_ 98 99 - Send transaction payload bytestring from Quorum to Tessera node. Tessera sends the transaction hash in the response back. 100 101 **`send`** - _Send transaction bytestring_ 102 103 - Similar to sendraw however request payload is in json format. Please see our [Swagger documentation](https://jpmorganchase.github.io/tessera-swagger/index.html) for object model. 104 105 **`storeraw`** - _Store transaction bytestring_ 106 107 - Store transaction bytestring from a third party to Tessera node. Tessera sends the transaction hash in the response back. 108 109 **`sendsignedtx`** - _Distribute signed transaction payload_ 110 111 - Send transaction payload identified by hash (returned by storeraw) from Quorum to Tessera node. Tessera sends the transaction hash in the response back. 112 113 **`receiveraw`** - _Receive transaction bytestring_ 114 115 - Receive decrypted bytestring of the transaction payload from Tessera to Quorum for transactions it is party to. 116 117 **`receive`** - _Receive transaction bytestring_ 118 119 - Similar to receiveraw however request payload is in json format. Please see our [Swagger documentation](https://jpmorganchase.github.io/tessera-swagger/index.html) for object model. 120 121 **`delete`** - _Delete a transaction_ 122 123 - Delete hashed encrypted payload stored in Tessera nodes. 124 125 For more interactions with the API see the [Swagger documentation](https://jpmorganchase.github.io/tessera-swagger/index.html).
