A brief overview of common standards in Bitcoin Cash: ticker symbol, currency code, units, logo, fees, formats

1. Bitcoin Cash Standards
An overview of standards in Bitcoin Cash
Bitcoin Cash Protocol
The Bitcoin Cash Protocol is documented on reference.cash.
Additional resources: bitcoincashresearch.org and cash.coin.dance.
Ticker symbol & currency code
The ticker symbol and de facto currency code for Bitcoin Cash is: BCH.
BCH is not compatible with ISO 4217, and while XBC is in conflict with European
Unit of Account 9, BCH is already widely adopted and accepted as a "standard".
A request has been submitted to ISO 4217 Maintenance Agency to recognize XCH
as a currency code for Bitcoin Cash on October 11, 2019.
Units
BCH is a standard in practice, but no formal agency for units is in place.
ABBREVIATION UNIT FRACTION
BCH bitcoin-cash 1
mBCH milli-bitcoin-cash 0.001
sat (plural: sats) satoshi (plural: satoshis) 0.000 00
Logo
The Bitcoin logo is tilted -20 degrees (instead of +20 degrees Bitcoin Core
uses). bch.info recommends a green logo (HTML color: #0AC18E). Example:
Transaction fees
Transaction fees are not standardized, but the recommended and most widely used
transaction fee setting is 1 sat/byte (one satoshi per byte).

2. URI scheme
The URI Scheme syntax for Bitcoin Cash is:
Syntax: bitcoincash:<address>[?[amount=<size>][&][label=<labe
l>][&][message=<message>]]
Sample: bitcoincash:qze75dks3vtgr3ezeg0jgkmezl2ttvp
ylyrk26dlsq?amount=0.02&label=URI%20Scheme%20Tes
t
IANA assignment
The URI Scheme syntax for SLP tokens on the Bitcoin Cash blockchain is:
Syntax: simpleledger:address?field1=param1&field2=param2
Sample: simpleledger:qze75dks3vtgr3ezeg0jgkmezl2ttv
pyly0dppclw7
IANA assignment
A proposal for a URI Scheme for Cash Accounts exists, but there is no
official IANA assignment. The syntax is similar to the bitcoincash URI Scheme.
Syntax: cashacct:<cashaccount>[?[amount=<size>][&][label=<lab
el>][&][message=<message>]]
Sample: cashacct:GeorgEngelmann#119777?amount=0.01&
label=0.01%20BCH%20for%20Georg%20Engelmann
Non-standard parameters such as op_return and op_return_raw have been
implemented in Electron Cash and other wallets.
CashAddr format
The CashAddr format is the standard address format for Bitcoin Cash
addresses. CashAddr was created to avoid confusion. Some wallets use
the CashAddr format while others use the Legacy format.
The specification is available on GitHub.
Payment requests
Payment Requests are requests for specific amounts typically used in merchant
transactions.
The specification is available on GitHub.
Cash Accounts

3. Cash Accounts are used to attach a human readable name to Bitcoin Cash
addresses. The Cash Accounts specification is available on GitLab.
For more information about Cash Accounts visit cashaccount.info.
CashShuffle
CashShuffle is a fully decentralized privacy enhancing protocol for Bitcoin Cash.
The CashShuffle specification is available on GitHub.
For more information about CashShuffle visit cashshuffle.com.
CashFusion
CashFusion provides high levels of privacy via a flexible scheme that allows an
arbitrary number of inputs and outputs of non-standard amounts. It provides
anonymous, trustless coordination with usually zero-knowledge of linkages
revealed to other players or the server. The CashFusion specification is available
on GitHub.
For more information about CashFusion visit: cashfusion.org.
CashChannels
CashChannels let users pre-approve future transactions, valued in any currency, to
another person or company.
The first draft of a CashChannels authentication template is available on GitHub.
Simple Ledger Protocol
Simple Ledger Protocol (SLP) is a simple token system. It is comparable with
Ethereum's ERC-20 Token Standard and provides greater integrity and
transparency than traditional forms of asset accounting and trading. Anyone can
use SLP to create their own token on the Bitcoin Cash blockchain. The
specifications are available on GitHub for SLP Type 1 and SLP NFT Type 1.
For more information about Simple Ledger Protocol visit simpleledger.cash.
Memo protocol
Memo protocol is a protocol for sending messages/attaching text on the Bitcoin
Cash blockchain.
The protocol specification is available on memo.cash.
Additional protocol codes have been implemented by Member and are available
on GitHub.
SmartBCH
Smart Bitcoin Cash (SmartBCH) is a sidechain for Bitcoin Cash and has an aim to
explore new ideas and unlock possibilities. It is compatible with Ethereum's EVM

4. and Web3 API and provides high throughput for DApps in a fast, secure, and
decentralized manner.
The SmartBCH documentation is available on docs.smartbch.org.
CashScript
CashScript is a high level language enabling basic smart contract functionality on
Bitcoin Cash. While these cash contracts are less powerful than Ethereum's smart
contracts, CashScript was in many ways inspired by Ethereum's development
ecosystem. Ethereum has always had one of the most accessible development
ecosystems in terms of tooling, and with CashScript we want to bring that
accessibility to Bitcoin Cash.
The CashScript documentation is available on cashscript.org.
CashID
CashID is an open protocol that allows secure authentication based on the public
key cryptography infrastructure that is currently present in the Bitcoin Cash
ecosystem.
The CashID specification is available on GitLab.
Bitcoin Cash
Bitcoin Cash (BCH) is a peer to peer electronic cash system. This means that
payments can be sent directly from one party to another without going through a
bank or third party. Peer to peer implies that either side can initiate a session and
has equal responsibility. Bitcoin Cash is fast, cheap, reliable, stable, simple and
secure. It is the most advanced form of cryptocurrency in the world. Enabling new
economies with low fee micro-transactions, large business transactions, and
permissionless spending.

Blockchain
A Blockchain is an ongoing chain of hash-based proof-of-work. Cryptocurrencies
are using a blockchain.

Cryptocurrency
A Cryptocurrency is a distributed network and online payment system using a
blockchain and strong encryption.

URI scheme

5. A URI scheme identifies a resource on the internet. There are URI schemes for
Bitcoin Cash and Simple Ledger Protocol allowing for clickable payment links and
payment handling in QR codes and other applications.
