x/authz

Abstract

x/authz is an implementation of a Cosmos SDK module, per ADR 30, that allows granting arbitrary privileges from one account (the granter) to another account (the grantee). Authorizations must be granted for a particular Msg service method one by one using an implementation of the Authorization interface.

Contents

Concepts

Authorization and Grant

The x/authz module defines interfaces and messages grant authorizations to perform actions on behalf of one account to other accounts. The design is defined in the ADR 030.

A grant is an allowance to execute a Msg by the grantee on behalf of the granter. Authorization is an interface that must be implemented by a concrete authorization logic to validate and execute grants. Authorizations are extensible and can be defined for any Msg service method even outside of the module where the Msg method is defined. See the SendAuthorization example in the next section for more details.

Note: The authz module is different from the auth (authentication) module that is responsible for specifying the base transaction and account types.

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/x/authz/authorizations.go#L11-L25

Built-in Authorizations

The Cosmos SDK x/authz module comes with following authorization types:

GenericAuthorization

GenericAuthorization implements the Authorization interface that gives unrestricted permission to execute the provided Msg on behalf of granter's account.

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/proto/cosmos/authz/v1beta1/authz.proto#L14-L22

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/x/authz/generic_authorization.go#L16-L29
  • msg stores Msg type URL.
SendAuthorization

SendAuthorization implements the Authorization interface for the cosmos.bank.v1beta1.MsgSend Msg.

  • It takes a (positive) SpendLimit that specifies the maximum amount of tokens the grantee can spend. The SpendLimit is updated as the tokens are spent.
  • It takes an (optional) AllowList that specifies to which addresses a grantee can send token.
https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/proto/cosmos/bank/v1beta1/authz.proto#L11-L30

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/x/bank/types/send_authorization.go#L29-L62
  • spend_limit keeps track of how many coins are left in the authorization.
  • allow_list specifies an optional list of addresses to whom the grantee can send tokens on behalf of the granter.
StakeAuthorization

StakeAuthorization implements the Authorization interface for messages in the staking module. It takes an AuthorizationType to specify whether you want to authorise delegating, undelegating or redelegating (i.e. these have to be authorised seperately). It also takes a required MaxTokens that keeps track of a limit to the amount of tokens that can be delegated/undelegated/redelegated. If left empty, the amount is unlimited. Additionally, this Msg takes an AllowList or a DenyList, which allows you to select which validators you allow or deny grantees to stake with.

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/proto/cosmos/staking/v1beta1/authz.proto#L11-L35

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/x/staking/types/authz.go#L15-L35

Gas

In order to prevent DoS attacks, granting StakeAuthorizations with x/authz incurs gas. StakeAuthorization allows you to authorize another account to delegate, undelegate, or redelegate to validators. The authorizer can define a list of validators they allow or deny delegations to. The Cosmos SDK iterates over these lists and charge 10 gas for each validator in both of the lists.

Since the state maintaining a list for granter, grantee pair with same expiration, we are iterating over the list to remove the grant (incase of any revoke of paritcular msgType) from the list and we are charging 20 gas per iteration.

State

Grant

Grants are identified by combining granter address (the address bytes of the granter), grantee address (the address bytes of the grantee) and Authorization type (its type URL). Hence we only allow one grant for the (granter, grantee, Authorization) triple.

  • Grant: 0x01 | granter_address_len (1 byte) | granter_address_bytes | grantee_address_len (1 byte) | grantee_address_bytes | msgType_bytes -> ProtocolBuffer(AuthorizationGrant)

The grant object encapsulates an Authorization type and an expiration timestamp:

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/proto/cosmos/authz/v1beta1/authz.proto#L24-L32

GrantQueue

We are maintaining a queue for authz pruning. Whenever a grant is created, an item will be added to GrantQueue with a key of expiration, granter, grantee.

In EndBlock (which runs for every block) we continuously check and prune the expired grants by forming a prefix key with current blocktime that passed the stored expiration in GrantQueue, we iterate through all the matched records from GrantQueue and delete them from the GrantQueue & Grants store.

https://github.com/T-ragon/cosmos-sdk/blob/5f4ddc6f80f9707320eec42182184207fff3833a/x/authz/keeper/keeper.go#L378-L403
  • GrantQueue: 0x02 | expiration_bytes | granter_address_len (1 byte) | granter_address_bytes | grantee_address_len (1 byte) | grantee_address_bytes -> ProtocalBuffer(GrantQueueItem)

The expiration_bytes are the expiration date in UTC with the format "2006-01-02T15:04:05.000000000".

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/x/authz/keeper/keys.go#L77-L93

The GrantQueueItem object contains the list of type urls between granter and grantee that expire at the time indicated in the key.

Messages

In this section we describe the processing of messages for the authz module.

MsgGrant

An authorization grant is created using the MsgGrant message. If there is already a grant for the (granter, grantee, Authorization) triple, then the new grant overwrites the previous one. To update or extend an existing grant, a new grant with the same (granter, grantee, Authorization) triple should be created.

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/proto/cosmos/authz/v1beta1/tx.proto#L35-L45

The message handling should fail if:

  • both granter and grantee have the same address.
  • provided Expiration time is less than current unix timestamp (but a grant will be created if no expiration time is provided since expiration is optional).
  • provided Grant.Authorization is not implemented.
  • Authorization.MsgTypeURL() is not defined in the router (there is no defined handler in the app router to handle that Msg types).

MsgRevoke

A grant can be removed with the MsgRevoke message.

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/proto/cosmos/authz/v1beta1/tx.proto#L69-L78

The message handling should fail if:

  • both granter and grantee have the same address.
  • provided MsgTypeUrl is empty.

NOTE: The MsgExec message removes a grant if the grant has expired.

MsgExec

When a grantee wants to execute a transaction on behalf of a granter, they must send MsgExec.

https://github.com/T-ragon/cosmos-sdk/blob/v0.47.0-rc1/proto/cosmos/authz/v1beta1/tx.proto#L52-L63

The message handling should fail if:

  • provided Authorization is not implemented.
  • grantee doesn't have permission to run the transaction.
  • if granted authorization is expired.

Events

The authz module emits proto events defined in the Protobuf reference.

Client

CLI

A user can query and interact with the authz module using the CLI.

Query

The query commands allow users to query authz state.

simd query authz --help
grants

The grants command allows users to query grants for a granter-grantee pair. If the message type URL is set, it selects grants only for that message type.

simd query authz grants [granter-addr] [grantee-addr] [msg-type-url]? [flags]

Example:

simd query authz grants cosmos1.. cosmos1.. /cosmos.bank.v1beta1.MsgSend

Example Output:

grants:
- authorization:
    '@type': /cosmos.bank.v1beta1.SendAuthorization
    spend_limit:
    - amount: "100"
      denom: stake
  expiration: "2022-01-01T00:00:00Z"
pagination: null
Transactions

The tx commands allow users to interact with the authz module.

simd tx authz --help
exec

The exec command allows a grantee to execute a transaction on behalf of granter.

  simd tx authz exec [tx-json-file] --from [grantee] [flags]

Example:

simd tx authz exec tx.json --from=cosmos1..
grant

The grant command allows a granter to grant an authorization to a grantee.

simd tx authz grant <grantee> <authorization_type="send"|"generic"|"delegate"|"unbond"|"redelegate"> --from <granter> [flags]

Example:

simd tx authz grant cosmos1.. send --spend-limit=100stake --from=cosmos1..
revoke

The revoke command allows a granter to revoke an authorization from a grantee.

simd tx authz revoke [grantee] [msg-type-url] --from=[granter] [flags]

Example:

simd tx authz revoke cosmos1.. /cosmos.bank.v1beta1.MsgSend --from=cosmos1..

gRPC

A user can query the authz module using gRPC endpoints.

Grants

The Grants endpoint allows users to query grants for a granter-grantee pair. If the message type URL is set, it selects grants only for that message type.

cosmos.authz.v1beta1.Query/Grants

Example:

grpcurl -plaintext \
    -d '{"granter":"cosmos1..","grantee":"cosmos1..","msg_type_url":"/cosmos.bank.v1beta1.MsgSend"}' \
    localhost:9090 \
    cosmos.authz.v1beta1.Query/Grants

Example Output:

{
  "grants": [
    {
      "authorization": {
        "@type": "/cosmos.bank.v1beta1.SendAuthorization",
        "spendLimit": [
          {
            "denom":"stake",
            "amount":"100"
          }
        ]
      },
      "expiration": "2022-01-01T00:00:00Z"
    }
  ]
}

REST

A user can query the authz module using REST endpoints.

/cosmos/authz/v1beta1/grants

Example:

curl "localhost:1317/cosmos/authz/v1beta1/grants?granter=cosmos1..&grantee=cosmos1..&msg_type_url=/cosmos.bank.v1beta1.MsgSend"

Example Output:

{
  "grants": [
    {
      "authorization": {
        "@type": "/cosmos.bank.v1beta1.SendAuthorization",
        "spend_limit": [
          {
            "denom": "stake",
            "amount": "100"
          }
        ]
      },
      "expiration": "2022-01-01T00:00:00Z"
    }
  ],
  "pagination": null
}

func RegisterQueryHandler 

func RegisterQueryHandler(ctx context.Context, mux *runtime.ServeMux, conn *grpc.ClientConn) error

RegisterQueryHandler registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over "conn".

func RegisterQueryHandlerClient 

func RegisterQueryHandlerClient(ctx context.Context, mux *runtime.ServeMux, client QueryClient) error

RegisterQueryHandlerClient registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over the given implementation of "QueryClient". Note: the gRPC framework executes interceptors within the gRPC handler. If the passed in "QueryClient" doesn't go through the normal gRPC flow (creating a gRPC client etc.) then it will be up to the passed in "QueryClient" to call the correct interceptors.

func RegisterQueryHandlerFromEndpoint 

func RegisterQueryHandlerFromEndpoint(ctx context.Context, mux *runtime.ServeMux, endpoint string, opts []grpc.DialOption) (err error)

RegisterQueryHandlerFromEndpoint is same as RegisterQueryHandler but automatically dials to "endpoint" and closes the connection when "ctx" gets done.

func RegisterQueryHandlerServer 

func RegisterQueryHandlerServer(ctx context.Context, mux *runtime.ServeMux, server QueryServer) error

RegisterQueryHandlerServer registers the http handlers for service Query to "mux". UnaryRPC :call QueryServer directly. StreamingRPC :currently unsupported pending https://github.com/grpc/grpc-go/issues/906. Note that using this registration option will cause many gRPC library features to stop working. Consider using RegisterQueryHandlerFromEndpoint instead.

func RegisterQueryServer 

func RegisterQueryServer(s grpc1.Server, srv QueryServer)

func ValidateGenesis 

func ValidateGenesis(data GenesisState) error

ValidateGenesis check the given genesis state has no integrity issues
