Features

PIN - The Secure Metadata Layer
"Pins" can be added to any transaction and broadcast to the network. Pins cannot be changed without changing the input to the signature, which would invalidate the transaction. If the transaction is invalidated by a change to a pin, the block containing the invalid transaction will become invalidated as well, causing a cascading effect invalidating every block chained after it. This feature can be deployed to a variety of file storage, indexing, and retrieval applications.
Proof-of-Work "FLO" Chain Details
Initially, pins were limited to 140 bytes. Currently, 1040 bytes of data can be stored on the blockchain with a maximum block size of 1MB. Currently, 1040 bytes of data can be stored on the blockchain with a maximum block size of 1MB. If the blocks are consistently filled, the maximum block size may be increased. With a target time of 40 seconds, PIN is fast. In fact, it is 15x faster than Bitcoin, and 3.75x faster than Litecoin. To further assist with transaction throughput, the maximum ancestor limit for an unspent transaction output (UTXO) chain has been increased from the Bitcoin default of 25 up to 1250. This permits large amounts of information to be efficiently indexed.
Additional PoW Security for FLO
PIN does not allow reorganizations of 100 or more blocks, and uses a continuity of Proof-of-Work blocks to secure the blockchain. Once a transaction receives 100 confirmations (~1 hour), it cannot be tampered with or removed from the blockchain.
