This block is called a PoS block. Coin-age - Coin age refers to the age of txn inputs. Coin age is equal to the number of coins sent times the average age on these coins. Age is measured in blocks. Age is reset to 1 block whenever a coin is sent AND whenever a coin provides a signature both mandatory and voluntary signatures count. Coin-age is used to calculate mandatory fees. Demurrage Fee - Chain Security is supported primarily through a demurrage tax on sent inputs. This tax proportional to average input age as measured in coin-years.
Active keys can avoid demurrage fees simply by remaining active. Dead keys must pay demurrage. The opportunity to evade demurrage motivates activity. Optional Fee - Fees are used to ration block space. Blocks select prioritize txns with high fees. If demurrage fees alone are insufficient to motivate txn inclusion, the user can add an optional fee to his txn. Fee Fund - Both optional fees and demurrage fees enter a fund, rather than being distributed directly to miners. Fees are added to the fund immediately, so there is a weak incentive to include high fee txns in blocks.
The PoW miner receives a distribution equal to 0. The first four mandatory signatories also receive 0. The PoS block miner receives 0. Use of a fund reduces volatility in mining reward. Root Private Key - The root private key has full spending and signing authority.

When significant balances are held, this key should be kept as an offline backup to guard against theft. Stake Signing Key - Private Key can delegate signing and sending authority to one other private key. The delegated key can sign blocks and has limited authority to send coins.
Authority to send coins is determined by two positive constants, t and k. The following txn rule limits the stake signing keys' spending authority:. Difficulty target periodically adjusted so that 1 PoW block arrives every 10 minutes. Each consecutive hash maps to an individual unspent output in the blockchain. This is essentially a lottery drawing two sets of five winners. The first five hashes map to mandatory signatures, the final five hashses map to voluntary signatures. Otherwise, the block is invalid and must be discarded. Otherwise, the message is dropped as spam.
These voluntary signatures can be inserted into any block within the next 6 blocks as special txns. These txns do not require fees. Block pairs that lose this race are orphaned. Unless attackers own a large share of stake, all types of PoW attacks are computationally infeasible. I think there are two types of known attacks: 1 Double-Spend 2 Denial of Service I consider approximations below.
The numbers are so favorable that consideration of exact statistics is not particularly interesting. Double spends rely on secrecy. In order to mine blocks in secret a PoW miner must select his 5 of his own public keys in the lottery. Even for extremely small hash aggregate rates, it is not practical to privately mine at a rate 10 billion times faster than all other miners combined.
An attacker who mines publicly could simply produce empty PoW blocks.

However, this would fail to deny service. The attacker cannot force the PoS miners to produce empty blocks. Therefore he cannot deny service regardless of how much hash rate he controls.

However, in a long secret chain, many stakeholders will have dead signatures. These dead stakeholders will not be able to sign the main chain, but not the attack chain. They will have a strong incentive to make sure the main chain wins because the attack chain will impose demurrage fees on them. This system introduces powerful incentives to maintain full nodes.
Many people argue that the lack of an incentive to maintain a full node is a problem in the bitcoin system.

Active keys must be maintaining full nodes. Otherwise they could not provide the voluntary signatures which prove their activity. Even very weak incentives are sufficient in this case. If almost all keys are associated with active nodes, then it is not necessary to motivate additional participation. This is costly for them. This means that the incentives to remain increase dramatically as participation falls.
This is equal to an annual of return of 2.
The alternative, inactivity, yields an annual return of I consider this a reasonable incentive level and participation rate. This is a very strong incentive and is almost certain to be sufficient, even if nodes are quite costly to maintain. Such individuals will likely use an online banking service which could store their limited spend key.
