Steem is an experimental Proof of Work blockchain with an unproven consensus algorithm.
- Currency Symbol STEEM
- 1.000 STEEM block reward at launch
- Approximately 100% APR long term inflation rate
Steem was announced on Bitcointalk prior to the start of any mining.

The mining algorithm used by Steem requires the owner to have access to the private key used by the account. This means it does not favor mining pools.
./steemd --miner=["accountname","${WIFPRIVATEKEY}"] --witness="accountname" --seed-node="52.38.66.234:2001"
Make sure that your accountname is unique and not already used by someone else or your proof of work might not be accepted by the blockchain.
See here for Linux and here for OSX (Apple).
Specifies whether to build with or without optimization and without or with the symbol table for debugging. Unless you are specifically debugging or running tests, it is recommended to build as release.
Builds steemd to be a consensus only low memory node. Data and fields not needed for consensus are not stored in the object database. This option is recommended for witnesses and seed-nodes.
Allows content to be updated using a patch rather than a complete replacement. If you do not need an API server or need to see the result of patching content then you can set this to OFF.
Clears old votes from memory that are not longer required for consensus.
Builds steemd for use in a private testnet. Also required for correctly building unit tests
The unit test target is make chain_test
This creates an executable ./tests/chain_test that will run all unit tests.
Tests are broken in several categories:
basic_tests // Tests of "basic" functionality
block_tests // Tests of the block chain
live_tests // Tests on live chain data (currently only past hardfork testing)
operation_tests // Unit Tests of Steem operations
operation_time_tests // Tests of Steem operations that include a time based component (ex. vesting withdrawals)
serialization_tests // Tests related of serialization
If you have not done so, install lcov brew install lcov
cmake -D BUILD_STEEM_TESTNET=ON -D ENABLE_COVERAGE_TESTING=true -D CMAKE_BUILD_TYPE=Debug .
make
