Memos in Stellar, Kin, and others

All you need to know about transaction memos Let’s jump straight to the point. Memos are pieces of text, hash, IDs or other data that are attached to transactions. They are entirely optional and have a number of different uses. Most importantly, custodial exchanges utilize memos as extensions of addresses. They rarely store the users’ funds in individual wallets, instead, they resort to assigning a single wallet to a number of people.

It has been tried and tested over the years, and has improved significantly since its’ launch.

Bitcoin SV

What is Bitcoin SV? Bitcoin Satoshi’s Vision (BSV) is the fork that formed after a conflict between two factions in the Bitcoin Cash (BCH) community. Craig Steven Wright and Calvin Ayre released Bitcoin SV in November 2018. As a rival to BCH, it aims to fulfill Satoshi Nakamoto’s original vision of Bitcoin’s whitepaper by maintaining a stable network, increasing capacity and instilling confidence among companies that utilize the BSV blockchain.

Ethereum Classic

What is Ethereum Classic? Ethereum Classic is a blockchain-based distributed computing platform featuring smart contract functionality. It was initially released as Ethereum in 2015 and continued as the original when some members of the Ethereum community rejected a hard fork made to restore the funds stolen in the infamous DAO hack. Ethereum Classic developers firmly believe in immutability and decentralization of the public ledger, and many of the users stick to the Code is Law principle.

Aion

What is Aion? Aion Network is a platform for building decentralized applications that was created in the fall of 2017 by Nuco, a team of former Deloitte executives. Its’ third-generation blockchain Aion-1 aims to manage robust applications and provide communication between separate blockchains. Federate, Scale, Spoke The main idea behind this platform is to solve the issue of limited operability between existing blockchains. Aion’s bridging mechanism allows an organization to send data and value between any AION-compliant public ledger and Ethereum, so that applications can operate across multiple chains.

Bitcoin cash

What is Bitcoin Cash? Bitcoin Cash (BCH) is a relatively recent hard fork of Bitcoin that was brought about in 2017 by a group of developers including Roger Ver, who felt like Bitcoin had become more of a digital investment rather than a transactional currency. They’ve increased the block size from 1MB to 32MB which allowed more transactions to be processed at a lower cost. What is a hard fork?

Dash

What is DASH? Dash (short for Digital Cash) is a fork of Bitcoin centered around anonymity and transaction speed. It was launched as Xcoin by Evan Duffield in 2014, later named Darkcoin, and finally rebranded to Dash in 2015. Mining & Masternodes Dash mining works similar to other cryptocurrencies where the foundation is a blockchain with a built-in Proof-of-Work (PoW) protocol and a decentralized public ledger. Governance of Dash is done through a form of decentralized autonomous organization (DAO), in which a number of “masternodes” perform standard hosting a copy of the blockchain, relaying messages, and validating transactions on the network.

Zcash

What is ZCash? Zcash is a decentralized cryptocurrency that was started as a fork of Bitcoin by Zooko Wilcox and his team in 2016. It is based on the Zerocash protocol developed by American and Israeli scientists and aims to provide enhanced privacy for its users compared to other cryptocurrencies such as Bitcoin. Strong Privacy Features There are two types of addresses that can be used to make transactions: a “t-address”, which is “transparent” and similar to a Bitcoin address, and a “z-address”, that is fully private and allows its users to shield a transaction from being visible to third parties in the blockchain.

Tezos

What is Tezos? Tezos is a self-amending smart contract platform that is the brainchild of Arthur and Kathleen Breitman. The Whitepaper was released in 2014, and three years later Tezos went on to have the biggest initial coin offering (ICO) by amount raised at the time. The project is now up and running, with its native cryptocurrency Tez or Tezzie (XTZ) having gained significant market capitalization. Baking & Governance From the start, Tezos was intended to be an evolving network, so token holders are allowed votes on pending protocol developments, for which there is a rigorous mathematical basis.
