Proof of Brain: Smart and Social Tokens

in #steem3 years ago

Token systems that reward users as they contribute to a token-based community system require
mechanisms for establishing and evaluating content’s social value: we call this “Proof-of-Brain.”

2 To differentiate it from the term for its blockchain, the correct spelling of Steem’s native digital token is
STEEM.

Steem provides a scalable blockchain protocol1
for publicly accessible and immutable content,
along with a fast and fee-less digital token (called STEEM)2 which enables people to earn the
currency by using their brain (what can be called “Proof-of-Brain”). The two building blocks
of this protocol, both blockchain and token, depend on each other for security, immutability
and longevity, and are therefore integral to each others’ existence. Steem has been successfully
operating for over a year, and has now exceeded both Bitcoin and Ethereum in number of
transactions processed.3
Compared to other blockchains, Steem stands out as the first publicly accessible database for
immutably stored content in the form of plain text, along with an in-built incentivization mechanism. This makes Steem a public publishing platform from which any Internet application may
pull and share data while rewarding those who contribute the most valuable content.
In the field of crypto-currencies, the unique properties of STEEM make it both “smart” and
“social”compared to others, such as bitcoin and ether. This stems from two new token features.
The first is a pool of tokens dedicated to incentivizing content creation and curation (called the
“rewards pool”). The second is a voting system that leverages the wisdom of the crowd to assess
the value of content and distribute tokens to it. These two unique properties when combined
are referred to as Proof-of-Brain, which is an entendre based on Proof-of-Work4
, meant to
emphasize the human work required to distribute tokens to community participants. Proof-ofBrain positions STEEM as a tool for building perpetually growing communities, which encourage
their members to add value to the community through the built in rewards structure.
In addition to these advancements in blockchain and token technology, Steem as a system
provides additional advanced features to enhance the user experience, such as Stolen Account
Recovery5
, escrow services, user promoted content, a reputation system, and savings accounts.
This is all done while providing users with three second confirmation times and zero fees on all
transactions. All of this allows it to support the mission of bringing smart and social currency to
publishers and community builders across the Internet.
