-| **`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 Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options) for command line options. |

 | `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://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI) 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://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) wiki page for details. |
 | `bootnode` | Stripped down version of our Ethereum client implementation that only takes part in the network node discovery protocol, but does not run any of the higher level application protocols. 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`). |
 | `gethrpctest` | Developer utility tool to support our [ethereum/rpc-test](https://github.com/ethereum/rpc-tests) test suite which validates baseline conformity to the [Ethereum JSON RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC) specs. Please see the [test suite's readme](https://github.com/ethereum/rpc-tests/blob/master/README.md) for details. |
 | `rlpdump` | Developer utility tool to convert binary RLP ([Recursive Length Prefix](https://github.com/ethereum/wiki/wiki/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`). |

-Binary Merkle Tree Hash is a hash function over arbitrary datachunks of limited size
-It is defined as the root hash of the binary merkle tree built over fixed size segments
-of the underlying chunk using any base hash function (e.g keccak 256 SHA3)
-
-It is used as the chunk hash function in swarm which in turn is the basis for the
-128 branching swarm hash http://swarm-guide.readthedocs.io/en/latest/architecture.html#swarm-hash
-
-The BMT is optimal for providing compact inclusion proofs, i.e. prove that a
-segment is a substring of a chunk starting at a particular offset
-The size of the underlying segments is fixed at 32 bytes (called the resolution
-of the BMT hash), the EVM word size to optimize for on-chain BMT verification
-as well as the hash size optimal for inclusion proofs in the merkle tree of the swarm hash.
-
-Two implementations are provided:
-
-* RefHasher is optimized for code simplicity and meant as a reference implementation
-* Hasher is optimized for speed taking advantage of concurrency with minimalistic
-  control structure to coordinate the concurrent routines
-  It implements the ChunkHash interface as well as the go standard hash.Hash interface
