swarm: release v0.4.1 (#1469)

* swarm/network/stream: remove old syncing test and replace it with two more granular tests, with the first one testing a full sync between two nodes (makes sure that when all subscriptions are established on all bins - all content is replicated from one node to the other), and a second test that adds a bigger amount of nodes to a star network topology, effectively making the pivot node have a depth > 0 to sync just certain content to the connected nodes (due to a star topology this test (always 1 hop) does not check that, for example, specific content is routed across multiple nodes, but assumes content should be only on the most proximate node)

* api, cmd/swarm-smoke, fuse, network, storage: fix data dir leak when using ephemeral filestore, pull test params to be easily adjustable

+## v0.4.1 (June 13, 2019)
+
+### Improvements
+
+* [#1465](https://github.com/ethersphere/swarm/pull/1465): network: bump proto versions due to change in OfferedHashesMsg
+* [#1428](https://github.com/ethersphere/swarm/pull/1428): swarm-smoke: add debug flag
+* [#1422](https://github.com/ethersphere/swarm/pull/1422): swarm/network/stream: remove dead code
+* [#1463](https://github.com/ethersphere/swarm/pull/1463): docker: create new dockerfiles that are context aware
+* [#1466](https://github.com/ethersphere/swarm/pull/1466): changelog for releases
+
+### Bug fixes
+
+* [#1460](https://github.com/ethersphere/swarm/pull/1460): storage: fix alignement panics on 32 bit arch
+* [#1422](https://github.com/ethersphere/swarm/pull/1422), [#19650](https://github.com/ethereum/go-ethereum/pull/19650): swarm/network/stream: remove dead code
+* [#1420](https://github.com/ethersphere/swarm/pull/1420): swarm, cmd: fix migration link, change loglevel severity
+* [#19594](https://github.com/ethereum/go-ethereum/pull/19594): swarm/api/http: fix bzz-hash to return ens resolved hash directly
+* [#19599](https://github.com/ethereum/go-ethereum/pull/19599): swarm/storage: fix SubscribePull to not skip chunks
+
+### Notes
+
+* Swarm has split the codebase ([go-ethereum#19661](https://github.com/ethereum/go-ethereum/pull/19661), [#1405](https://github.com/ethersphere/swarm/pull/1405)) from [ethereum/go-ethereum](https://github.com/ethereum/go-ethereum). The code is now under [ethersphere/swarm](https://github.com/ethersphere/swarm)
+* New docker images (>=0.4.0) can now be found under https://hub.docker.com/r/ethersphere/swarm
+
+## v0.4.0 (May 17, 2019)
+
+### Changes
+
+* Implemented parallel feed lookups within Swarm Feeds
+* Updated syncing protocol subscription algorithm
+* Implemented EIP-1577 - Multiaddr support for ENS
+* Improved LocalStore implementation
+* Added support for syncing tags which provide the ability to measure how long it will take for an uploaded file to sync to the network
+* Fixed data race bugs within PSS
+* Improved end-to-end integration tests
+* Various performance improvements and bug fixes
+* Improved instrumentation - metrics and OpenTracing traces
+
+### Notes
+This release is not backward compatible with the previous versions of Swarm due to the new LocalStore implementation. If you wish to keep your data, you should run a data migration prior to running this version.
+
+BZZ network ID has been updated to 4.
+
+Swarm v0.4.0 introduces major changes to the existing codebase. Among other things, the storage layer has been rewritten to be more modular and flexible in a manner that will accommodate for our future needs. Since Swarm at this point does not provide any storage guarantees, we have made the decision to not impose any migrations on the nodes that we maintain as part of the public test network, nor on our users. We have provided a [manual](https://github.com/ethersphere/swarm/blob/master/docs/Migration-v0.3-to-v0.4.md) for those of you who are running private deployments and would like to migrate your data to the new local storage schema.

-
-  To do so, attach the following notices to the program.  It is safest

+Swarm is a distributed storage platform and content distribution service, a native base layer service of the ethereum web3 stack. The primary objective of Swarm is to provide a decentralized and redundant store for dapp code and data as well as block chain and state data. Swarm is also set out to provide various base layer services for web3, including node-to-node messaging, media streaming, decentralised database services and scalable state-channel infrastructure for decentralised service economies.

 ## Building the source
 
-For prerequisites and detailed build instructions please read the [Installation Instructions](https://geth.ethereum.org/docs/install-and-build/installing-geth).
+Building Swarm requires Go (version 1.11 or later).
 
-Building `geth` requires both a Go (version 1.14 or later) and a C compiler. You can install
-them using your favourite package manager. Once the dependencies are installed, run
+To simply compile the `swarm` binary without a `GOPATH`:
 
-```shell
-make geth
+    $ git clone https://github.com/ethersphere/swarm
+    $ cd swarm
+    $ make swarm
+
+You will find the binary under `./build/bin/swarm`.
+
+To build a vendored `swarm` using `go get` you must have `GOPATH` set. Then run:
+
+    go get -d github.com/ethersphere/swarm
+
+    go install github.com/ethersphere/swarm/cmd/swarm
+
+## Running Swarm
+
+Going through all the possible command line flags is out of scope here, but we've enumerated a few common parameter combos to get you up to speed quickly on how you can run your own Swarm node.
+
+To run Swarm you need an Ethereum account. Download and install [Geth](https://geth.ethereum.org) if you don't have it on your system. You can create a new Ethereum account by running the following command:
+
+    geth account new
+
+You will be prompted for a password:
+
+    Your new account is locked with a password. Please give a password. Do not forget this password.
+    Passphrase:
+    Repeat passphrase:
+
+Once you have specified the password, the output will be the Ethereum address representing that account. For example:
+
+    Address: {2f1cd699b0bf461dcfbf0098ad8f5587b038f0f1}
+
+Using this account, connect to Swarm with
+
+    swarm --bzzaccount <your-account-here>
+
+    # in our example
+
+    swarm --bzzaccount 2f1cd699b0bf461dcfbf0098ad8f5587b038f0f1
+
+
+### Verifying that your local Swarm node is running
+
+When running, Swarm is accessible through an HTTP API on port 8500.
+
+Confirm that it is up and running by pointing your browser to http://localhost:8500
+
+### Ethereum Name Service resolution
+
+The Ethereum Name Service is the Ethereum equivalent of DNS in the classic web. In order to use ENS to resolve names to Swarm content hashes (e.g. `bzz://theswarm.eth`), `swarm` has to connect to a `geth` instance, which is synced with the Ethereum mainnet. This is done using the `--ens-api` flag.
+
+    swarm --bzzaccount <your-account-here> \
+          --ens-api '$HOME/.ethereum/geth.ipc'
+
+    # in our example
+
+    swarm --bzzaccount 2f1cd699b0bf461dcfbf0098ad8f5587b038f0f1 \
+          --ens-api '$HOME/.ethereum/geth.ipc'
+
+For more information on usage, features or command line flags, please consult the Documentation.
+
+
+## Documentation
+
+Swarm documentation can be found at [https://swarm-guide.readthedocs.io](https://swarm-guide.readthedocs.io).
+
+
+## Developers Guide
+
+### Go Environment
+
+We assume that you have Go v1.11 installed, and `GOPATH` is set.
+
+You must have your working copy under `$GOPATH/src/github.com/ethersphere/swarm`.
+
+Most likely you will be working from your fork of `swarm`, let's say from `github.com/nirname/swarm`. Clone or move your fork into the right place:
+
+```
+git clone git@github.com:nirname/swarm.git $GOPATH/src/github.com/ethersphere/swarm
 ```
 
-or, to build the full suite of utilities:
 
-```shell
-make all
+### Vendored Dependencies
+
+All dependencies are tracked in the `vendor` directory. We use `govendor` to manage them.
+

+### Testing
+
+This section explains how to run unit, integration, and end-to-end tests in your development sandbox.
+
+Testing one library:
+
+```
+go test -v -cpu 4 ./api
 ```
 
-## Executables
+Note: Using options -cpu (number of cores allowed) and -v (logging even if no error) is recommended.
 
-The go-ethereum project comes with several wrappers/executables found in the `cmd`
-directory.
+Testing only some methods:
 
-|    Command    | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |
-| :-----------: | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-|  **`geth`**   | Our main Ethereum CLI client. It is the entry point into the Ethereum network (main-, test- or private net), capable of running as a full node (default), archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as a gateway into the Ethereum network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. `geth --help` and the [CLI page](https://geth.ethereum.org/docs/interface/command-line-options) for command line options.          |
-|   `clef`    | Stand-alone signing tool, which can be used as a backend signer for `geth`.  |
-|   `devp2p`    | Utilities to interact with nodes on the networking layer, without running a full blockchain. |
-|   `abigen`    | Source code generator to convert Ethereum contract definitions into easy to use, compile-time type-safe Go packages. It operates on plain [Ethereum contract ABIs](https://docs.soliditylang.org/en/develop/abi-spec.html) with expanded functionality if the contract bytecode is also available. However, it also accepts Solidity source files, making development much more streamlined. Please see our [Native DApps](https://geth.ethereum.org/docs/dapp/native-bindings) page for details. |

It can be used as a lightweight bootstrap node to aid in finding peers in private networks.                                                                                                                                                                                                                                                                 |
-|     `evm`     | Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow isolated, fine-grained debugging of EVM opcodes (e.g. `evm --code 60ff60ff --debug run`).                                                                                                                                                                                                                                                                     |
-|   `rlpdump`   | Developer utility tool to convert binary RLP ([Recursive Length Prefix](https://eth.wiki/en/fundamentals/rlp)) dumps (data encoding used by the Ethereum protocol both network as well as consensus wise) to user-friendlier hierarchical representation (e.g. `rlpdump --hex CE0183FFFFFFC4C304050583616263`).                                                                                                                                                                                                                                 |
-|   `puppeth`   | a CLI wizard that aids in creating a new Ethereum network.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           |

-## Running `geth`
-
-Going through all the possible command line flags is out of scope here (please consult our
-[CLI Wiki page](https://geth.ethereum.org/docs/interface/command-line-options)),
-but we've enumerated a few common parameter combos to get you up to speed quickly
-on how you can run your own `geth` instance.
-
-### Hardware Requirements
-
-Minimum:
-
-* CPU with 2+ cores
-* 4GB RAM
-* 1TB free storage space to sync the Mainnet
-* 8 MBit/sec download Internet service
-
-Recommended:
-
-* Fast CPU with 4+ cores
-* 16GB+ RAM
-* High Performance SSD with at least 1TB free space
-* 25+ MBit/sec download Internet service
-
-### Full node on the main Ethereum network
-
-By far the most common scenario is people wanting to simply interact with the Ethereum
-network: create accounts; transfer funds; deploy and interact with contracts. For this
-particular use-case the user doesn't care about years-old historical data, so we can
-sync quickly to the current state of the network. To do so:
-
-```shell
-$ geth console
+```
+go test -v -cpu 4 ./api -run TestMethod
 ```
 
-This command will:
- * Start `geth` in snap sync mode (default, can be changed with the `--syncmode` flag),
-   causing it to download more data in exchange for avoiding processing the entire history
-   of the Ethereum network, which is very CPU intensive.
- * Start up `geth`'s built-in interactive [JavaScript console](https://geth.ethereum.org/docs/interface/javascript-console),
-   (via the trailing `console` subcommand) through which you can interact using [`web3` methods](https://github.com/ChainSafe/web3.js/blob/0.20.7/DOCUMENTATION.md) 
-   (note: the `web3` version bundled within `geth` is very old, and not up to date with official docs),
-   as well as `geth`'s own [management APIs](https://geth.ethereum.org/docs/rpc/server).
-   This tool is optional and if you leave it out you can always attach to an already running
-   `geth` instance with `geth attach`.
+Note: here all tests with prefix TestMethod will be run, so if you got TestMethod, TestMethod1, then both!
 
-### A Full node on the Görli test network
+Running benchmarks:
 
-Transitioning towards developers, if you'd like to play around with creating Ethereum
-contracts, you almost certainly would like to do that without any real money involved until
-you get the hang of the entire system. In other words, instead of attaching to the main
-network, you want to join the **test** network with your node, which is fully equivalent to
-the main network, but with play-Ether only.
-
-```shell
-$ geth --goerli console
+```
+go test -v -cpu 4 -bench . -run BenchmarkJoin
 ```
 
-The `console` subcommand has the exact same meaning as above and they are equally
-useful on the testnet too. Please, see above for their explanations if you've skipped here.
 
-Specifying the `--goerli` flag, however, will reconfigure your `geth` instance a bit:
+### Profiling Swarm
 
- * Instead of connecting the main Ethereum network, the client will connect to the Görli
-   test network, which uses different P2P bootnodes, different network IDs and genesis
-   states.
- * Instead of using the default data directory (`~/.ethereum` on Linux for example), `geth`
-   will nest itself one level deeper into a `goerli` subfolder (`~/.ethereum/goerli` on
-   Linux). Note, on OSX and Linux this also means that attaching to a running testnet node
-   requires the use of a custom endpoint since `geth attach` will try to attach to a
-   production node endpoint by default, e.g.,
-   `geth attach <datadir>/goerli/geth.ipc`. Windows users are not affected by
-   this.
+This section explains how to add Go `pprof` profiler to Swarm
 
-*Note: Although there are some internal protective measures to prevent transactions from
-crossing over between the main network and test network, you should make sure to always
-use separate accounts for play-money and real-money. Unless you manually move
-accounts, `geth` will by default correctly separate the two networks and will not make any
-accounts available between them.*
+If `swarm` is started with the `--pprof` option, a debugging HTTP server is made available on port 6060.
 
-### Full node on the Rinkeby test network
+You can bring up http://localhost:6060/debug/pprof to see the heap, running routines etc.
 
-Go Ethereum also supports connecting to the older proof-of-authority based test network
-called [*Rinkeby*](https://www.rinkeby.io) which is operated by members of the community.
+By clicking full goroutine stack dump (clicking http://localhost:6060/debug/pprof/goroutine?debug=2) you can generate trace that is useful for debugging.
 
-```shell
-$ geth --rinkeby console
+
+### Metrics and Instrumentation in Swarm
+
+This section explains how to visualize and use existing Swarm metrics and how to instrument Swarm with a new metric.
+
+Swarm metrics system is based on the `go-metrics` library.
+
+The most common types of measurements we use in Swarm are `counters` and `resetting timers`. Consult the `go-metrics` documentation for full reference of available types.
+
+```
+# incrementing a counter
+metrics.GetOrRegisterCounter("network.stream.received_chunks", nil).Inc(1)
+
+# measuring latency with a resetting timer
+start := time.Now()
+t := metrics.GetOrRegisterResettingTimer("http.request.GET.time"), nil)
+...
+t := UpdateSince(start)
 ```
 
-### Full node on the Ropsten test network
+#### Visualizing metrics
 
-In addition to Görli and Rinkeby, Geth also supports the ancient Ropsten testnet. The
-Ropsten test network is based on the Ethash proof-of-work consensus algorithm. As such,
-it has certain extra overhead and is more susceptible to reorganization attacks due to the
-network's low difficulty/security.
+Swarm supports an InfluxDB exporter. Consult the help section to learn about the command line arguments used to configure it:
 
-```shell
-$ geth --ropsten console
+```
+swarm --help | grep metrics
 ```
 
-*Note: Older Geth configurations store the Ropsten database in the `testnet` subdirectory.*
+We use Grafana and InfluxDB to visualise metrics reported by Swarm. We keep our Grafana dashboards under version control at https://github.com/ethersphere/grafana-dashboards. You could use them or design your own.
 
-### Configuration
+We have built a tool to help with automatic start of Grafana and InfluxDB and provisioning of dashboards at https://github.com/nonsense/stateth, which requires that you have Docker installed.
 
-As an alternative to passing the numerous flags to the `geth` binary, you can also pass a
-configuration file via:
+Once you have `stateth` installed, and you have Docker running locally, you have to:
 
-```shell
-$ geth --config /path/to/your_config.toml
+1. Run `stateth` and keep it running in the background
+```
+stateth --rm --grafana-dashboards-folder $GOPATH/src/github.com/ethersphere/grafana-dashboards --influxdb-database metrics
 ```
 
-To get an idea how the file should look like you can use the `dumpconfig` subcommand to
-export your existing configuration:
-
-```shell
-$ geth --your-favourite-flags dumpconfig
+2. Run `swarm` with at least the following params:
+```
+--metrics \
+--metrics.influxdb.export \
+--metrics.influxdb.endpoint "http://localhost:8086" \
+--metrics.influxdb.username "admin" \
+--metrics.influxdb.password "admin" \
+--metrics.influxdb.database "metrics"
 ```
 
-*Note: This works only with `geth` v1.6.0 and above.*
+3. Open Grafana at http://localhost:3000 and view the dashboards to gain insight into Swarm.
 
-#### Docker quick start
 
-One of the quickest ways to get Ethereum up and running on your machine is by using
-Docker:
+## Public Gateways
 
-```shell
-docker run -d --name ethereum-node -v /Users/alice/ethereum:/root \
-           -p 8545:8545 -p 30303:30303 \
-           ethereum/client-go
-```
+Swarm offers a local HTTP proxy API that Dapps can use to interact with Swarm. The Ethereum Foundation is hosting a public gateway, which allows free access so that people can try Swarm without running their own node.
 
-This will start `geth` in snap-sync mode with a DB memory allowance of 1GB just as the
-above command does.  It will also create a persistent volume in your home directory for
-saving your blockchain as well as map the default ports. There is also an `alpine` tag
-available for a slim version of the image.
+The Swarm public gateways are temporary and users should not rely on their existence for production services.
 
-Do not forget `--http.addr 0.0.0.0`, if you want to access RPC from other containers
-and/or hosts. By default, `geth` binds to the local interface and RPC endpoints are not
-accessible from the outside.
+The Swarm public gateway can be found at https://swarm-gateways.net and is always running the latest `stable` Swarm release.
 
-### Programmatically interfacing `geth` nodes
+## Swarm Dapps
 
-As a developer, sooner rather than later you'll want to start interacting with `geth` and the
-Ethereum network via your own programs and not manually through the console. To aid
-this, `geth` has built-in support for a JSON-RPC based APIs ([standard APIs](https://eth.wiki/json-rpc/API)
-and [`geth` specific APIs](https://geth.ethereum.org/docs/rpc/server)).
-These can be exposed via HTTP, WebSockets and IPC (UNIX sockets on UNIX based
-platforms, and named pipes on Windows).
+You can find a few reference Swarm decentralised applications at: https://swarm-gateways.net/bzz:/swarmapps.eth
 
-The IPC interface is enabled by default and exposes all the APIs supported by `geth`,
-whereas the HTTP and WS interfaces need to manually be enabled and only expose a
-subset of APIs due to security reasons. These can be turned on/off and configured as
-you'd expect.
+Their source code can be found at: https://github.com/ethersphere/swarm-dapps
 
-HTTP based JSON-RPC API options:
+## Contributing
 
-  * `--http` Enable the HTTP-RPC server
-  * `--http.addr` HTTP-RPC server listening interface (default: `localhost`)
-  * `--http.port` HTTP-RPC server listening port (default: `8545`)
-  * `--http.api` API's offered over the HTTP-RPC interface (default: `eth,net,web3`)
-  * `--http.corsdomain` Comma separated list of domains from which to accept cross origin requests (browser enforced)
-  * `--ws` Enable the WS-RPC server
-  * `--ws.addr` WS-RPC server listening interface (default: `localhost`)
-  * `--ws.port` WS-RPC server listening port (default: `8546`)
-  * `--ws.api` API's offered over the WS-RPC interface (default: `eth,net,web3`)
-  * `--ws.origins` Origins from which to accept websockets requests
-  * `--ipcdisable` Disable the IPC-RPC server
-  * `--ipcapi` API's offered over the IPC-RPC interface (default: `admin,debug,eth,miner,net,personal,shh,txpool,web3`)
-  * `--ipcpath` Filename for IPC socket/pipe within the datadir (explicit paths escape it)
+Thank you for considering to help out with the source code! We welcome contributions from
+anyone on the internet, and are grateful for even the smallest of fixes!
 
-You'll need to use your own programming environments' capabilities (libraries, tools, etc) to
-connect via HTTP, WS or IPC to a `geth` node configured with the above flags and you'll
-need to speak [JSON-RPC](https://www.jsonrpc.org/specification) on all transports. You
-can reuse the same connection for multiple requests!
-
-**Note: Please understand the security implications of opening up an HTTP/WS based
-transport before doing so! Hackers on the internet are actively trying to subvert
-Ethereum nodes with exposed APIs! Further, all browser tabs can access locally
-running web servers, so malicious web pages could try to subvert locally available
-APIs!**
-
-### Operating a private network
-
-Maintaining your own private network is more involved as a lot of configurations taken for
-granted in the official networks need to be manually set up.
-
-#### Defining the private genesis state
-
-First, you'll need to create the genesis state of your networks, which all nodes need to be
-aware of and agree upon. This consists of a small JSON file (e.g. call it `genesis.json`):
-
-```json
-{
-  "config": {
-    "chainId": <arbitrary positive integer>,
-    "homesteadBlock": 0,
-    "eip150Block": 0,
-    "eip155Block": 0,
-    "eip158Block": 0,
-    "byzantiumBlock": 0,
-    "constantinopleBlock": 0,
-    "petersburgBlock": 0,
-    "istanbulBlock": 0,
-    "berlinBlock": 0,
-    "londonBlock": 0
-  },
-  "alloc": {},
-  "coinbase": "0x0000000000000000000000000000000000000000",
-  "difficulty": "0x20000",
-  "extraData": "",
-  "gasLimit": "0x2fefd8",
-  "nonce": "0x0000000000000042",
-  "mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000",
-  "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
-  "timestamp": "0x00"
-}
-```
-
-The above fields should be fine for most purposes, although we'd recommend changing
-the `nonce` to some random value so you prevent unknown remote nodes from being able
-to connect to you. If you'd like to pre-fund some accounts for easier testing, create
-the accounts and populate the `alloc` field with their addresses.
-
-```json
-"alloc": {
-  "0x0000000000000000000000000000000000000001": {
-    "balance": "111111111"
-  },
-  "0x0000000000000000000000000000000000000002": {
-    "balance": "222222222"
-  }
-}
-```
-
-With the genesis state defined in the above JSON file, you'll need to initialize **every**
-`geth` node with it prior to starting it up to ensure all blockchain parameters are correctly
-set:
-
-```shell
-$ geth init path/to/genesis.json
-```
-
-#### Creating the rendezvous point
-
-With all nodes that you want to run initialized to the desired genesis state, you'll need to
-start a bootstrap node that others can use to find each other in your network and/or over
-the internet. The clean way is to configure and run a dedicated bootnode:
-
-```shell
-$ bootnode --genkey=boot.key
-$ bootnode --nodekey=boot.key
-```
-
-With the bootnode online, it will display an [`enode` URL](https://eth.wiki/en/fundamentals/enode-url-format)
-that other nodes can use to connect to it and exchange peer information. Make sure to
-replace the displayed IP address information (most probably `[::]`) with your externally
-accessible IP to get the actual `enode` URL.
-
-*Note: You could also use a full-fledged `geth` node as a bootnode, but it's the less
-recommended way.*
-
-#### Starting up your member nodes
-
-With the bootnode operational and externally reachable (you can try
-`telnet <ip> <port>` to ensure it's indeed reachable), start every subsequent `geth`
-node pointed to the bootnode for peer discovery via the `--bootnodes` flag. It will
-probably also be desirable to keep the data directory of your private network separated, so
-do also specify a custom `--datadir` flag.
-
-```shell
-$ geth --datadir=path/to/custom/data/folder --bootnodes=<bootnode-enode-url-from-above>
-```
-
-*Note: Since your network will be completely cut off from the main and test networks, you'll
-also need to configure a miner to process transactions and create new blocks for you.*
-
-#### Running a private miner
-
-Mining on the public Ethereum network is a complex task as it's only feasible using GPUs,
-requiring an OpenCL or CUDA enabled `ethminer` instance. For information on such a
-setup, please consult the [EtherMining subreddit](https://www.reddit.com/r/EtherMining/)
-and the [ethminer](https://github.com/ethereum-mining/ethminer) repository.
-
-In a private network setting, however a single CPU miner instance is more than enough for
-practical purposes as it can produce a stable stream of blocks at the correct intervals
-without needing heavy resources (consider running on a single thread, no need for multiple
-ones either). To start a `geth` instance for mining, run it with all your usual flags, extended
-by:
-
-```shell
-$ geth <usual-flags> --mine --miner.threads=1 --miner.etherbase=0x0000000000000000000000000000000000000000
-```
-
-Which will start mining blocks and transactions on a single CPU thread, crediting all
-proceedings to the account specified by `--miner.etherbase`. You can further tune the mining
-by changing the default gas limit blocks converge to (`--miner.targetgaslimit`) and the price
-transactions are accepted at (`--miner.gasprice`).

-# Using the smartcard wallet
-
-## Requirements
-
-  * A USB smartcard reader
-  * A keycard that supports the status app
-  * PCSCD version 4.3 running on your system **Only version 4.3 is currently supported**
-
-## Preparing the smartcard
-
-  **WARNING: FOILLOWING THESE INSTRUCTIONS WILL DESTROY THE MASTER KEY ON YOUR CARD. ONLY PROCEED IF NO FUNDS ARE ASSOCIATED WITH THESE ACCOUNTS**
-
-  You can use status' [keycard-cli](https://github.com/status-im/keycard-cli) and you should get _at least_ version 2.1.1 of their [smartcard application](https://github.com/status-im/status-keycard/releases/download/2.2.1/keycard_v2.2.1.cap)
-
-  You also need to make sure that the PCSC daemon is running on your system.
-
-  Then, you can install the application to the card by typing:
-
-  ```
-  keycard install -a keycard_v2.2.1.cap && keycard init
-  ```
-
-  At the end of this process, you will be provided with a PIN, a PUK and a pairing password. Write them down, you'll need them shortly.
-
-  Start `geth` with the `console` command. You will notice the following warning:
-
-  ```
-  WARN [04-09|16:58:38.898] Failed to open wallet                    url=keycard://044def09                          err="smartcard: pairing password needed"
-  ```
-
-  Write down the URL (`keycard://044def09` in this example). Then ask `geth` to open the wallet:
-
-  ```
-  > personal.openWallet("keycard://044def09", "pairing password")
-  ```
-
-  The pairing password has been generated during the card initialization process.
-  
-  The process needs to be repeated once more with the PIN:
-
-  ```
-  > personal.openWallet("keycard://044def09", "PIN number")
-  ```
-  
-  If everything goes well, you should see your new account when typing `personal` on the console:
-
-  ```
-  > personal
-  WARN [04-09|17:02:07.330] Smartcard wallet account derivation failed url=keycard://044def09 err="Unexpected response status Cla=0x80, Ins=0xd1, Sw=0x6985"
-  {
-    listAccounts: [],
-    listWallets: [{
-        status: "Empty, waiting for initialization",
-        url: "keycard://044def09"
-    }],
-    ...
-  }
-  ```
-
-  So the communication with the card is working, but there is no key associated with this wallet. Let's create it:
-
-  ```
-  > personal.initializeWallet("keycard://044def09")
-  "tilt ... impact"
-  ```
-
-  You should get a list of words, this is your seed so write them down. Your wallet should now be initialized:
-
-  ```
-  > personal.listWallets
-  [{
-    accounts: [{
-        address: "0x678b7cd55c61917defb23546a41803c5bfefbc7a",
-        url: "keycard://044d/m/44'/60'/0'/0/0"
-    }],
-    status: "Online",
-    url: "keycard://044def09"
-  }]
-  ```
-
-  You're all set!
-
-## Usage
-
-  1. Start `geth` with the `console` command
-  2. Check the card's URL by checking `personal.listWallets`:
-
-```
-  listWallets: [{
-      status: "Online, can derive public keys",
-      url: "keycard://a4d73015"
-  }]
-```
-
-  3. Open the wallet, you will be prompted for your pairing password, then PIN:
-
-```
-personal.openWallet("keycard://a4d73015")
-```
-
-  4. Check that creation was successful by typing e.g. `personal`. Then use it like a regular wallet.
-
-## Known issues
-
-  * Starting geth with a valid card seems to make firefox crash.
-  * PCSC version 4.4 should work, but is currently untested

-//
-// This implementation of smartcard wallets have a different interaction process
-// to other types of hardware wallet. The process works like this:
-//
-// 1. (First use with a given client) Establish a pairing between hardware
-//    wallet and client. This requires a secret value called a 'pairing password'.
-//    You can pair with an unpaired wallet with `personal.openWallet(URI, pairing password)`.
-// 2. (First use only) Initialize the wallet, which generates a keypair, stores
-//    it on the wallet, and returns it so the user can back it up. You can
-//    initialize a wallet with `personal.initializeWallet(URI)`.
-// 3. Connect to the wallet using the pairing information established in step 1.
-//    You can connect to a paired wallet with `personal.openWallet(URI, PIN)`.
-// 4. Interact with the wallet as normal.

-// Before you touch the protocol files, you need to be aware of a breaking change
-// that occurred between firmware versions 1.7.3->1.8.0 (Model One) and 2.0.10->
-// 2.1.0 (Model T). The Ethereum address representation was changed from the 20
-// byte binary blob to a 42 byte hex string. The upstream protocol buffer files
-// only support the new format, so blindly pulling in a new spec will break old
-// devices!
-//
-// The Trezor devs had the foresight to add the string version as a new message
-// code instead of replacing the binary one. This means that the proto file can
-// actually define both the old and the new versions as optional. Please ensure
-// that you add back the old addresses everywhere (to avoid name clash. use the
-// addressBin and addressHex names).
-//
-// If in doubt, reach out to @karalabe.
-
-// To regenerate the protocol files in this package:
-//   - Download the latest protoc https://github.com/protocolbuffers/protobuf/releases
-//   - Build with the usual `./configure && make` and ensure it's on your $PATH
-//   - Delete all the .proto and .pb.go files, pull in fresh ones from Trezor
