A piece of data that requires significant computation to find. In bitcoin, miners must find a numeric solution to the SHA256 algorithm that meets a network-wide target, the difficulty target.
reward::
An amount included in each new block as a reward by the network to the miner who found the Proof-of-Work solution. It is currently 12.5BTC per block.

RIPEMD-160::
RIPEMD-160 is a 160-bit cryptographic hash function. RIPEMD-160 is a strengthened version of RIPEMD with a 160-bit hash result, and is expected to be secure for the next ten years or more.
ScriptSig or Signature Script, is the data generated by a spender which is almost always used as variables to satisfy a pubkey script.
secret key (aka private key)::
The secret number that unlocks bitcoin sent to the corresponding address. A secret key looks like +5J76sF8L5jTtzE96r66Sf8cka9y44wdpJjMwCxR3tzLh3ibVPxh+.

Segregated Witness::
Segregated Witness is a proposed upgrade to the Bitcoin protocol which technological innovation separates signature data from Bitcoin transactions. Segregated Witness is a proposed soft fork; a change that technically makes Bitcoin’s protocol rules more restrictive.
