We’ve seen that Zcash is doing plenty to keep itself in contention in the privacy coin contest. The development history is good, they frequently inform the community of their progress, they are backed by a solid team with research experience, and their Github page is active.

Zcash is also hosting a conference in Montreal, called Zcon0, at the end of June, the details of which we will shortly receive.

For example, Monero is one of the hottest privacy coins. It utilizes a different system called ring signatures to ensure privacy, and it has the benefit of being on the market much longer than its competitors. Some believe Zcash’s Sapling upgrade will make scaling and mobile transactions possible, setting it up to overtake Monero. For that, we’ll have to wait until September. In the meantime, it will be interesting to see how the development of different privacy coins pans out.

Zcash is a cryptocurrency based on a decentralized Blockchain, aiming for making transactions more private than they are in the Bitcoin blockchain. ZEC (Zcash token) transactions, like Bitcoin’s, are published in a public Blockchain, but unlike Bitcoin Zcash allows users to selectively disclose private information.

Zcash provides two types of keys: a “view key” and a “spend key.” While the latter is used to spend funds, the former is used to allow some individuals to see private information about your transactions. View keys may be used for an audit or sharing information without disclosing it to the entire world.

Zcash also provides encrypted memo fields that offer an opportunity of delivering messages to the recipient of the transaction that only a view key holder can see. This can be used to deliver simple messages, or such things as payment code sand confidential or commercial information.

A STEEM wallet is an application that allows you to manage your STEEM, possibly in the form of STEEM Dollars, VESTS, or STEEM (STEEM Tokens). Some STEEM wallets offer integrated access to STEEM posts, and may also have built-in exchanges to assist with the different types of STEEM currency.

STEEM. STEEM is the foundational cryptocurrency of the Steemit network. STEEM can be exchanged for bitcoin or other cryptocurrencies via several prominent exchanges. In order to cast votes, however, you need to turn your STEEM into Steem Power (SP). This process is known as “powering up.” You can also convert STEEM into Steem Dollars.
Steem Power (SP). When you turn STEEM into SP, you are investing it in the network as equity. One unit of STEEM, vested as SP, equates to one vote. Those with the most SP to contribute have the greatest influence over which content is elevated to the top. Upvotes and downvotes, or “flags,” from users holding large amounts of SP are worth more than users with less SP. Additionally, around 90% of new STEEM that is created goes to users who hold a lot of SP, which creates an incentive for participants to invest their earnings back into the network. Rate limits are in place on converting SP back into STEEM, known as “powering down.”
Steem Dollars. Steem Dollars, valued at 1:1 with the US dollar, are a unit used to represent a short-term debt. Holding Steem Dollars is described in Steem’s whitepaper as a way of lending the community the value of one US dollar, which is designed to foster growth.

An SMT is a native digital asset on the Steem blockchain. SMTs can be launched by anyone to help monetize online content and create incentives to encourage desired user behavior.

SMTs are like Ethereum's ERC-20 tokens, but with certain built-in ‘Proof-of-Brain’ properties and a token distribution reward system designed specifically for digital content businesses.

Steem is explained as a fundamental unit of account on a platform called Steemit. Steemit is a Blockchain-based platform where users can publish content and vote on it like on every other social media platform, but with the difference that on Stemmit, they are rewarded with tokens. 

The Steem network gives new Steem units to publishers and voters every day. Steem can be exchanged either on Steem Power (SP) or Steem Backed Dollars (SPD). Steem Power is a token used to upvote content, which helps to get a revenue both for a voter (in SP) and for a publisher in (SPD) proportionate to how much Steem Power the voter has. Steem Powered Dollars represent an amount of Steem equal to 1 USD. SMD helps to protect content creators from the volatility of the Steem cryptocurrency by promising them that they’ll get a fixed amount of money, no matter how much Steem will cost when they cash out.
