Account RecoveryIf a user’s account is compromised, they may change their keys using their private owner key.
In the event that the attacker is able to compromise the private owner key and change the
password on the account, the user has 30 days to submit a previously functional private key
through Steem’s industry-first stolen account recovery process, and regain control over their
account.		Steem

AppBaseAppBase enables different cores, or even different computers, to maintain
different parts of the Steem blockchain. This is significantly more efficient than requiring every
core, and every computer in the network maintain the entire blockchain. Modularizing the
blockchain enables it to take full advantage of the modular nature of computers. This is one
necessary step in the long process of creating a fully parallel, fully optimized blockchain.		Steem

Bandwidth Rate Limiting for Fee-less OperationsWhenever users perform blockchain operations such as token transfers, posting content, and
voting, it uses up a portion of their bandwidth. If a user exceeds their bandwidth allowance, they
must wait to perform additional actions until their bandwidth recharges.
Bandwidth limits adjust based on network use, so users have a higher bandwidth allowance
when the network usage is low. The amount of bandwidth that an account is allowed is directly
proportional to the amount of Steem Power a user has, so users can always increase their
bandwidth allowance by getting additional Steem Power.		Steem

ChainBaseChainBase has faster load and exit times, supports parallel access to the database and is more
robust against crashes than its predecessor. It also has less frequent database corruption, allows
instant “snapshotting” of entire database state, and can serve more RPC requests from the same
memory		Steem

Escrow SystemThe Steem blockchain provides a way for users to send coins to each other with a third party
designated as an escrow service. The user acting as the escrow service is able to determine if the
terms of the agreement have been met, and either allow the funds to be released to the receiver
or returned to the sender.		Steem

Hierarchical Private Key StructureThese private keys are the Posting, Active and Owner. The posting key allows accounts to post,
comment, edit, vote, resteem, and follow/mute other accounts. The active key is meant for
more sensitive tasks such as transferring funds, power up/down transactions, converting Steem
Dollars, voting for witnesses, placing market orders, and resetting the posting key. The owner
key is only meant for use when necessary. It is the most powerful key because it can change any
key of an account, including the owner key, and to prove ownership during an Account Recovery.		Steem

IPFS (InterPlanetary File System)InterPlanetary File System (IPFS) is a protocol and network designed to create a content-addressable, peer-to-peermethod of storing and sharing hypermedia in a distributed file system.[2] IPFS was initially designed by Juan Benet, and is now an open-source project developed with help from the community.

MultiSig (NEM version)NEM implements m of n multisignature, where m ≤ n. This means that m out of a total of n signatories must sign a transaction before it can be broadcast onto the blockchainNEM
31
MultiSigblockchain allows an authority to be split across multiple entities, so that multiple
users may share the same authority, or multiple entities are required to authorize a transaction in
order for it to be valid.		Steem; Zilliqa

Multiple Reward BeneficiariesFor any given post there may be a number of different people who have a financial interest in
the reward. This includes the author, possible co-authors, referrers, hosting providers, blogs that
embedded blockchain comments, and tool developers. Whatever website or tool that is used to
construct a post or comment will have the ability to set how rewards from that comment are
divided among various parties. This allows for various forms of collaboration, as well as a way
for platforms that are built on top of the Steem blockchain to collect a portion of the rewards
from their users		Steem

Native Name SystemThe Steem blockchain
uses each participant’s user name as their wallet address, which bolsters the user experience for
participants who attempt to send tokens because they can verify the addresses from their own

PoS (Proof-of-Stake)In PoS-based cryptocurrencies, such as Peercoin invented by Sunny King and Scott Nadal, the creator of the next block is chosen via various combinations of random selection and wealth or age.Peercoin; Ethereum
39
PoA (Proof-of-Authority)In PoA-based networks, transactions and blocks are validated by approved accounts, known as validators.[2] Validators run software allowing them to put transactions in blocks. The process is automated and does not require validators to be constantly monitoring their computers.Ethereum
40
PoI (Proof-of-Importance)At a high level, the primary inputs are:
Net transfers: how much has been ‘spent’ in the past 30 days, with more recent transactions weighted more heavily.
Vested amount of currency for purposes of creating blocks.
Cluster nodes: accounts that are part of interlinked clusters of activity are weighted slightly more heavily than outliers or hubs (which just link clusters but aren’t part of them).		NEM
41
PoR (Proof-of-Reputation)There have been several identity staked Proof-of-authority systems proposed which share some similarities to PoR, including one from Ethereum co-founder Gavin Wood [29]. Menlo One builds upon these and other works to implement a system which incentivises virtuous behavior, provides resistance against bad actors, and is fast enough for a modern web experienceMenlo One

pBFT - practical Byzantine Fault TolerancePractical Byzantine Fault Tolerance, in short pBFT. The protocol comes with several advantages from being computationally cheap, and hence incurring a small energy footprint to providing transaction finality that eliminates the need for confirmations.Zilliqa

Reward Pool of SteemThe rate that new tokens are generated was set to 9.5% per year starting in December 2016,and decreases at a rate of 0.01% every 250,000 blocks, or about 0.5% per year. The inflationwill continue decreasing at this rate until it reaches 0.95%, after a period of approximately 20.5years.Of the supply of new tokens created by the Steem blockchain every year, 75% of those tokenscompose the “rewards pool” which are distributed to content creators and content curators.15% are distributed to vested token holders, and 10% are distributed to Witnesses, the blockproducers cooperating inside Steem’s DPoS consensus protocol.Steem

SBD (Steem Blockchain Dollar)SBD tokens are designed to be pegged closely to one USD, so that users who receive them can
know approximately how much they are worth in “real dollar” terms. SBD tokens also offer a
relatively stable currency for users to hold if they are looking to preserve their account value
relative to USD		Steem
50
Security Time LocksThe Steem blockchain allows users to store their STEEM and SBD tokens in a savings account,
so that the funds may not be withdrawn until after a three day waiting period. In addition,
STEEM that is held in the 13 week vesting schedule may only be withdrawn at a rate of 1/13
per week, after an initial waiting period of seven days		Steem

Stealth AdressesThey allow and require the sender to create random one-time addresses for every transaction on behalf of the recipient. The recipient can publish just one address, yet have all of his/her incoming payments go to unique addresses on the blockchain, where they cannot be linked back to either the recipient's published address or any other transactions' addresses.Monero
