Account Operations

The set of methods in this section correspond to querying the states of Blockstack token accounts. Each token account is represented by an account address, which is a Crockford base-32 encoding of the RIPEMD160 hash of the SHA256 hash of one or more keys, plus a version byte and a 4-byte SHA256 checksum. Internally, Blockstack account addresses are generated and represented in the same way as p2pkh and p2sh Bitcoin addresses – that is, a Blockstack account addresses are in 1-to-1 correspondance with Bitcoin addresses (Blockstack account addresses simply use a different encoding alphabet). We have a reference library for helping developers generate and convert between Bitcoin and Blockstack addresses.

Right now, an account can only own Stacks tokens (designiated in the API as having a toke type STACKS). However, in the future Blockstack may be upgraded to support owning many different kinds of app-specific tokens. The API presented here is designed to accomodate this possible development.

Get account status
GET/v1/accounts/{address}/{tokenType}/status

Get the status of an account’s current token allocation. The current number of tokens held by the account’s address is equal to the difference between the credit_value and debit_value. These two numbers always increase and are accounted in the smallest possible unit of the token type (e.g. microStacks for the STACKS token). Programs that parse these values should be aware of this, and should use an appropriate numeric representation like BigInteger when parsing them.

The last transaction’s ID (txid) and transaction offset (vtxindex) are given. If vtxindex is 0, then the transaction ID corresponds to a “sentinal” transaction in Blockstack Core that indicates tokens getting generated or unlocked. These transaction IDs will not appear in any block explorer, since they do not correspond to “real” transactions.

Get account balance
GET/v1/accounts/{address}/{tokenType}/balance

Get the number of tokens held by a particular account, given the account’s address and the token type.

Note that the value returned by this endpoint can be very large, since the token balances are integers that represent the number of smallest units of the token (e.g. microStacks for the STACKS token).

This endpoint returns a zero balance for accounts and token types that do not exist.

Get account statuses at block
GET/v1/accounts/{address}/history/{blockNum}

Get the status(es) of an account at a particular block height. If the account was affected by a transaction at the given block height, the states the account passed through will be returned (i.e. at least two entries). If the account was not affected at this block height, then the last state the account was in at that block height will be returned.

If there is more than one state, then the states will be listed in reverse order chronologically, with the latest state as the first entry.

If the account does not exist, then an empty list will be returned.

Resolve DID
GET/v1/dids/{did}

Resolve a Blockstack DID to its DID document object (DDO). In practice, the DDO is stored in the same way as a user profile, but a few extra DDO-specific fields will be filled in by this endpoint (namely, @context and publicKey).

Blockstack DIDs correspond to non-revoked, non-expired names. A DID will not resolve if its underlying name is revoked or expired, or if the DID does not correspond to an existing name.
