Refers to keeping a reserve of bitcoin offline. Cold storage is achieved when Bitcoin private keys are created and stored in a secure offline environment. Cold storage is important for anyone with bitcoin holdings. Online computers are vulnerable to hackers and should not be used to store a significant amount of bitcoin.

confirmations::
Once a transaction is included in a block, it has one confirmation. As soon as _another_ block is mined on the same blockchain, the transaction has two confirmations, and so on. Six or more confirmations is considered sufficient proof that a transaction cannot be reversed.

A peer-to-peer network that propagates transactions and blocks to every bitcoin node on the network.
nonce::
The "nonce" in a Bitcoin block is a 32-bit (4-byte) field whose value is set so that the hash of the block will contain a run of leading zeros. The rest of the fields may not be changed, as they have a defined meaning.

off-chain transactions::
An off-chain transaction is the movement of value outside of the block chain. While an on-chain transaction—usually referred to as simply __a transaction__—modifies the blockchain and depends on the blockchain to determine its validity an off-chain transaction relies on other methods to record and validate the transaction.

Operation codes from the Bitcoin Script language which push data or perform functions within a pubkey script or signature script.

P2WSH::
The difference between P2SH and P2WSH (Pay-to-Witness-Script-Hash) is about the cryptographic proof location change from the scriptSig field to the witness field and the scriptPubKey that is also modified.
Paper wallet::
paper wallet::
In the most specific sense, a paper wallet is a document containing all of the data necessary to generate any number of Bitcoin private keys, forming a wallet of keys. However, people often use the term to mean any way of storing bitcoin offline as a physical document. This second definition also includes paper keys and redeemable codes.
Payment channels::
A Micropayment Channel or Payment Channel is class of techniques designed to allow users to make multiple Bitcoin transactions without committing all of the transactions to the Bitcoin block chain. In a typical payment channel, only two transactions are added to the block chain but an unlimited or nearly unlimited number of payments can be made between the participants.

Pooled mining::
pooled mining::
Pooled mining is a mining approach where multiple generating clients contribute to the generation of a block, and then split the block reward according the contributed processing power.
Proof-of-stake::
Proof-of-stake (PoS) is a method by which a cryptocurrency blockchain network aims to achieve distributed consensus. Proof of stake asks users to prove ownership of a certain amount of currency (their "stake" in the currency).

Proof-Of-Work::
Proof-of-Work::
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.
