Adaptive Block Reward
Adaptive Reward based on historical data - emission formula slightly decreases block reward each block as a function of all coinbase transaction amounts previously generated. Reward for blocks 1-88,000 based on a speed factor per minute of 22, resulting in a reward ranging from 549.755797504 to 548.315910839. Reward for blocks 88,001 and greater based on a speed factor per minute of 25, resulting in a reward starting at 4,386.527155990 at block 88,001. Blocks 227001 and greater have a block time of 20 seconds, the reward was reduced to maintain a speed factor per minute of 25, resulting in a reward starting at 1414.513079344 at block 227001. Uncle blocks receive a total reward of 155% of what would have been the mined block reward for the same block; Reward is split 50% to Uncle, 105% to Mined Block. See the latest block coinbase transaction amount for the current block reward. Solo's emission schedule is slower than bitcoin and does not include disruptive halving events.
All project related infrastructure costs, bounties, marketing costs and listing fees have been paid out of personal funds, with no ICO and no crowd funding.
Premine and Early Contributions
Solo is a continuation of a side project started by NERVA developer angrywasp and included a zero block (premine) reward of ~70,368, representing 0.00038% of the total supply. At block 66001 a hard fork was activated, after this time the founder no longer participated in development. At the time of the fork ~36,318,207 coins had been minted representing ~0.196% of the total supply. As of block 256000 (April 17, 2019) current supply was ~689,220,912 representing 3.7% of the total supply. Current supply can be found using the command print_coinbase_tx_sum in the daemon command line.
Simple Extended Consensus Resolution, SECOR is a key feature of Solo. By activating SECOR, faster block times can be achieved without the use of Master Nodes, DAG or some other centralized solution. Faster block times result in more transaction throughput making the blockchain more scalable.
