OraclesIn cryptography, a random oracle is an oracle that responds to every unique query with a random response chosen uniformly from its output domain. They are typically used when the proof cannot be carried out using weaker assumptions on the cryptographic hash function.
Orphan"Orphan block" os also known as a “detached block” and refers to a valid block outside of the main chain. It can appear when two miners produce blocks simultaniously or when a block undergoes cyber attack.
Orphan blockA valid block which is not a part of the main chain, but which was instead part of a fork that was discarded.
Over The Counter (OTC)Over-the-counter (OTC) or off-exchange trading is done directly between two parties, without the supervision of an exchange. It is contrasted with exchange trading, which occurs via exchanges. A stock exchange has the benefit of facilitating liquidity, providing transparency, and maintaining the current market price. In an OTC trade, the price is not necessarily publicly disclosed.
OverboughtOverbought describes a period of time where there has been a significant and consistent upward move in price over a period of time without much pullback. This is clearly defined by a chart showing price movement from the “lower-left to upper-right” like the chart shown below.
OversoldThe term Oversold describes a period of time where there has been a significant and consistent downward move in price over a period of time without much pullback. Basically a move from the “upper-left to the lower-right.”
PPairTrading pair of two crytos. For instance, BTC/ETH.
Paper WalletPaper Wallet is a physical piece of paper you print out that stores your altcoins in a secure, offline environment. Paper wallets are inherently impervious to hacking and other forms of internet theft but vulnerable to acts of nature (fire and flood), burglary, and human error (simply losing your wallet). Basically, all a paper wallet contains is a printed public key and private key for a respective address. The data is NOT stored on a computer. Often a paper wallet has a QR code of the public and private keys to make it easy when you need to get the key values on your computer or phone — you just scan the paper instead of manually typing the keys out.
Paper WalletA physical document that contains one's private key or mnemonic phrase.
Peer to Peer (P2P)A network, in which computer systems are connected to each other via the Internet. Files can be shared directly between systems on the network without the need of a central server. In other words, each computer on a P2P network becomes a file server as well as a client.

Private KeyPrivate Key is a private address that is paired with your public key. Private keys allow you to spend your coins or take them out of your wallet for using. The private key looks very similar to a public key but it’s slightly longer. You can get your public key from a private key but you can not get a private key from a public key. It is the key to the balance of the address. Whoever holds the private key owns the value of the address.
Private Key / Secret KeyA tiny bit of code that is paired with a public key to set off algorithms for text encryption and decryption. It is created as part of public key cryptography during asymmetric-key encryption and used to decrypt and transform a message to a readable format. Public and private keys are paired for secure communication, such as email.

Public KeyPublic Key is like the bank account for your personal digital currency. It is where you store your coins. If you have multiple types of coins, you must have a separate wallet for each type. A wallet is a collection of public keys. So a wallet can contain one public key or one hundred. How much you decide to put in each is up to you and there is no cost. An example of a Bitcoin public key : 14euyjBip1t2aWax5ZSg5YGHR8WW34CnEj. Anyone can send you coins or you can transfer coins to other address as long as you have the private key.

StakingStaking in the cryptocurrency world means that the efficiency of the network is boosted by buying cryptocurrencies to verify transactions. As a reward for staking cryptocurrency, some companies offer incentives to buyers. These incentives are offered as interest. Staking also provides an alternative way of making money by holding coins. Asides from that, as the value of the coins keep on increasing so do the rewards.
StakingThe act of locking up one's coins or tokens to help verify transactions for cryptocurrencies with Proof of Stake consensus mechanisms. Stakers earn staking rewards for providing this service.
