1. A decentralized consensus system for tracking transferable digital objects, the system comprising: (5) (3)

i. a plurality of node computers, each node computer in said plurality of node computers including a processing unit, some amount of memory accessed by said processing unit, and a network interface operatively coupled to said processing unit and a wide area network connecting said plurality of node computers;

ii. each node computer within said plurality of node computers including a consensus system software application running on said processing unit of said node computer; and

iii. said consensus system software application adapted to: 1) load an initial ledger containing a first set of digital objects;

2) connect to peer nodes over said wide area network;

3) download block chain data from connected peer nodes, said block chain data including one or more data block chains, each data block chain within said one or more data block chains including a set of data blocks, each data block within said set of data blocks including a set of transactions and signed by one or more block signers within a set of block signers;

4) check validity of said block chain data using a set of consensus rules to determine whether data blocks within said set of data blocks follow a set of protocol rules;

5) where said block chain data includes more than one data block chain, determine a consensus data block chain based on a most committed stake metric, wherein said consensus data block chain includes a set of valid transactions and a set of valid data blocks;

6) pass said set of valid transactions and said set of valid data blocks to one or more connected peers over said wide area network, wherein said set of valid transactions and said set of valid data blocks are verified to follow said set of protocol rules; and

7) maintain a current ledger, said current ledger built from said initial ledger, said valid transactions and said valid data blocks.

2. The decentralized consensus system of claim 1, wherein: (0) (2)

i) each digital object within said first set of digital objects includes a balance and a collection of votes for a set of block signer candidates; and

ii) said consensus system software application is further adapted to: 1) determine an approval width for each said balance based on said collection of votes for said balance;

2) order said first set of digital objects based on said approval width;

3) determine a set of intermediary approvals, a summed approval and an approval height for each block signer candidate within said set of block signer candidates based said balance and said collection of votes;

4) from said set of block signer candidates, select a first block signer candidate with a highest summed approval;

5) from said set of block signer candidates, select a second block signer candidate with a next highest summed approval;

6) determine a set of mapped approval widths of said second block signer candidate; and

7) where a sum of said set of mapped approval widths is below a predetermined threshold, select said second block signer candidate to sign data blocks.

3. The decentralized consensus system of claim 1, wherein said consensus system software application is further adapted to reject a first block within said set of data blocks when said first block fails to follow said set of protocol rules. (0)

4. The decentralized consensus system of claim 1, wherein: (0) (2)

5. The decentralized consensus system of claim 1, wherein: (0) (2)

6. The decentralized consensus system of claim 1, wherein said consensus system software application is further adapted to: (0) (6)

i) generate a private and public pair including a private key and a public key;

ii) display a transaction that sends stake to said public key;

iii) build and sign a first new transaction transmitting a stake to a different user;

iv) broadcast said first new transaction to said connected peer nodes;

v) build and sign a second new transaction including a vote; and

vi) broadcast said second new transaction to said connected peer nodes.
