+A Florincoin blockchain REST and web socket API service for [Flocore Node](https://github.com/bitpay/flocore-node).
 
-*insight API* is an open-source bitcoin blockchain REST

-*Insight API* allows to develop bitcoin-related applications (such as wallets) that
+```bashl
-require certain information from the blockchain that bitcoind does not provide.

+```
 
-A blockchain explorer front-end has been developed on top of *Insight API*. It can
+The API endpoints will be available by default at: `http://localhost:3001/flosight-api/`
-be downloaded at [Github Insight Repository](https://github.com/bitpay/insight).
-
-## Warning
-  Insight file sync does not work with **bitcoind**  v0.10 
-  In order to use Insigtht you must set the environment variable INSIGHT_FORCE_RPC_SYNC = 1  
-  We are working on `bitcore-node` to replace Insight-api. Check `bitcore-node` on  [github](https://github.com/bitpay/bitcore-node).
 
 ## Prerequisites
 
-* **bitcoind** - Download and Install [Bitcoin](http://bitcoin.org/en/download)
+- [Flocore 5.x](https://github.com/bitpay/flocore)
 
-*insight API* needs a *trusted* bitcoind node to run. *insight API* will connect to the node
+**Note:** You can use an existing Florincoin data directory, however `txindex`, `addressindex`, `timestampindex` and `spentindex` needs to be set to true in `florincoin.conf`, as well as a few other additional fields.
-through the RPC API, bitcoin peer-to-peer protocol, and will even read its raw block .dat files for syncing.
 
-Configure bitcoind to listen to RPC calls and set `txindex` to true.
+## Notes on Upgrading from v0.3
-The easiest way to do this is by copying `./etc/bitcoind/bitcoin.conf` to your
-bitcoin data directory (usually `~/.bitcoin` on Linux, `%appdata%\Bitcoin\` on Windows,
-or `~/Library/Application Support/Bitcoin` on Mac OS X).
-
-bitcoind must be running and must have finished downloading the blockchain **before** running *insight API*.
-
-
-* **Node.js v0.10.x** - Download and Install [Node.js](http://www.nodejs.org/download/).
-
-* **NPM** - Node.js package manager, should be automatically installed when you get node.js.
-
-
-## Quick Install
-  Check the Prerequisites section above before installing.
-
-  To install Insight API, clone the main repository:
-
-    $ git clone https://github.com/bitpay/insight-api && cd insight-api
-
-  Install dependencies:
-
-    $ npm install
-
-  Run the main application:
-
-    $ node insight.js
-
-  Then open a browser and go to:
-
-    http://localhost:3001
-
-  Please note that the app will need to sync its internal database
-  with the blockchain state, which may take some time. You can check
-  sync progress at http://localhost:3001/api/sync.
-
-
-## Configuration
-
-All configuration is specified in the [config](config/) folder, particularly the [config.js](config/config.js) file. There you can specify your application name and database name. Certain configuration values are pulled from environment variables if they are defined:
 
+The unspent outputs format now has `satoshis` and `height`:

+    "height": 300001
+  }
+]
+```
+The `timestamp` property will only be set for unconfirmed transactions and `height` can be used for determining block order. The `confirmationsFromCache` is nolonger set or necessary, confirmation count is only cached for the time between blocks.
 
+There is a new `GET` endpoint or raw blocks at `/rawblock/<blockHash>`:
+
+Response format:
+```
+{
+  "rawblock": "blockhexstring..."
+}
 ```
 
-Make sure that bitcoind is configured to [accept incoming connections using 'rpcallowip'](https://en.bitcoin.it/wiki/Running_Bitcoin).
+There are a few changes to the `GET` endpoint for `/addr/[:address]`:
 
-In case the network is changed (testnet to livenet or vice versa) levelDB database needs to be deleted. This can be performed running:
+- The list of txids in an address summary does not include orphaned transactions
-```util/sync.js -D``` and waiting for *insight* to synchronize again.  Once the database is deleted, the sync.js process can be safely interrupted (CTRL+C) and continued from the synchronization process embedded in main app.
+- The txids will be sorted in block order
+- The list of txids will be limited at 1000 txids
+- There are two new query options "from" and "to" for pagination of the txids (e.g. `/addr/[:address]?from=1000&to=2000`)
 
-## Synchronization
+Some additional general notes:
+- The transaction history for an address will be sorted in block order
+- The response for the `/sync` endpoint does not include `startTs` and `endTs` as the sync is no longer relevant as indexes are built in florincoind.
+- The endpoint for `/peer` is no longer relevant connection to florincoind is via ZMQ.
+- `/tx` endpoint results will now include block height, and spentTx related fields will be set to `null` if unspent.
+- `/block` endpoint results does not include `confirmations` and will include `poolInfo`.
 
-The initial synchronization process scans the blockchain from the paired bitcoind server to update addresses and balances. *insight-api* needs exactly one trusted bitcoind node to run. This node must have finished downloading the blockchain before running *insight-api*.
+## Notes on Upgrading from v0.2
 
-While *insight* is synchronizing the website can be accessed (the sync process is embedded in the webserver), but there may be missing data or incorrect balances for addresses. The 'sync' status is shown at the `/api/sync` endpoint.
+Some of the fields and methods are not supported:
 
-The blockchain can be read from bitcoind's raw `.dat` files or RPC interface.
+The `/tx/<txid>` endpoint JSON response will not include the following fields on the "vin"
-Reading the information from the `.dat` files is much faster so it's the
+object:
-recommended (and default) alternative. `.dat` files are scanned in the default
+- `doubleSpentTxId` // double spends are not currently tracked
-location for each platform (for example, `~/.bitcoin` on Linux). In case a
+- `isConfirmed` // confirmation of the previous output
-non-standard location is used, it needs to be defined (see the Configuration section).
+- `confirmations` // confirmations of the previous output
-As of June 2014, using `.dat` files the sync process takes 9 hrs.
+- `unconfirmedInput`
-for livenet and 30 mins. for testnet.
 
-While synchronizing the blockchain, *insight-api* listens for new blocks and
+The `/tx/<txid>` endpoint JSON response will not include the following fields on the "vout"
-transactions relayed by the bitcoind node. Those are also stored on *insight-api*'s database.
+object.
-In case *insight-api* is shutdown for a period of time, restarting it will trigger
+- `spentTs`
-a partial (historic) synchronization of the blockchain. Depending on the size of
-that synchronization task, a reverse RPC or forward `.dat` syncing strategy will be used.
 
-If bitcoind is shutdown, *insight-api* needs to be stopped and restarted
+The `/status?q=getTxOutSetInfo` method has also been removed due to the query being very slow and locking florincoind.
-once bitcoind is restarted.
 
-### Syncing old blockchain data manually
+Plug-in support for Flosight API is also no longer available, as well as the endpoints:
+- `/email/retrieve`
+- `/rates/:code`
 
-  Old blockchain data can be manually synced issuing:
+Caching support has not yet been added in the v0.3 upgrade.
 
-    $ util/sync.js
+## Query Rate Limit
 
-  Check util/sync.js --help for options, particulary -D to erase the current DB.
+To protect the server, flosight-api has a built it query rate limiter. It can be configurable in `flocore-node.json` with:
+``` json
+  "servicesConfig": {
+    "flosight-api": {
+      "rateLimiterOptions": {
+        "whitelist": ["::ffff:127.0.0.1"]
+      }
+    }
+  }
+```
+With all the configuration options available: https://github.com/bitpay/flosight-api/blob/master/lib/ratelimiter.js#L10-17
 
-  *NOTE*: there is no need to run this manually since the historic synchronization
+Or disabled entirely with:
-  is built in into the web application. Running *insight-api* normally will trigger
+``` json
-  the historic sync automatically.
+  "servicesConfig": {
-
+    "flosight-api": {
-
+      "disableRateLimiter": true
-### DB storage requirement
+    }
-
+  }
-To store the blockchain and address related information, *insight-api* uses LevelDB.
+  ```
-Two DBs are created: txs and blocks. By default these are stored on
+  
-
-  ``~/.insight/``
-
-Please note that some older versions of Insight-API store that on `<insight's root>/db`.
-
-This can be changed at config/config.js. As of June 2014, storing the livenet blockchain takes ~35GB of disk space (2GB for the testnet).
-
-## Development
-
-To run insight locally for development with grunt:
-
-```$ NODE_ENV=development grunt```
-
-To run the tests
-
-```$ grunt test```
-
-
-Contributions and suggestions are welcome at [insight-api github repository](https://github.com/bitpay/insight-api).
-
-## Caching schema
-
-Since v0.2 a new cache schema has been introduced. Only information from transactions with
-INSIGHT_SAFE_CONFIRMATIONS settings will be cached (by default SAFE_CONFIRMATIONS=6). There
-are 3 different caches:
- * Number of confirmations
- * Transaction output spent/unspent status
- * scriptPubKey for unspent transactions
-
-Cache data is only populated on request, i.e., only after accessing the required data for
-the first time, the information is cached, there is not pre-caching procedure.  To ignore
-cache by default, use INSIGHT_IGNORE_CACHE. Also, address related calls support `?noCache=1`
-to ignore the cache in a particular API request.
-
-## API
-
-By default, insight provides a REST API at `/api`, but this prefix is configurable from the var `apiPrefix` in the `config.js` file.
-
-The end-points are:
