Zcash, launched in 2016, stands out from Bitcoin and other cryptocurrencies due to its innovative use of zero-knowledge proofs, which enable fully encrypted transactions on a public blockchain. This groundbreaking technology allows for enhanced privacy and security, ensuring that transaction details such as sender, recipient, and amount remain confidential while still being verifiable. Another unique aspect of Zcash is the implementation of the Founders' Reward, a mechanism designed to incentivize and fund the project's early development. For the first four years, 20% of the block rewards were allocated to the project's founders, early investors, the Electric Coin Company (ECC) team, and advisors, supporting the ongoing development and sustainability of the Zcash ecosystem. This approach to funding and development distinguishes Zcash from other cryptocurrencies and showcases its innovative spirit. (GPT 4)
Between the launch of Zcash in 2016 and the halving in November 2020, 10.5 million ZEC were issued via the block reward. 8.4 million to miners and 2.1 million to founders. Here is a detailed breakdown of this early history of the Zcash block reward.

Initial Block Rewards and the Slow-Start Mechanism
When Zcash was launched, it introduced a unique "slow-start" mechanism. For the first 20,000 blocks, the block reward gradually increased from 0.000625 ZEC to 12.5 ZEC. This initial phase was designed to mitigate risks associated with potential software bugs or vulnerabilities by limiting the initial distribution rate of ZEC. Additionally, it aimed to allow a broader range of participants to start mining without giving insiders a significant advantage from the outset. By gradually ramping up the block rewards, the slow-start mechanism ensured that those interested in supporting the network could do so on more equal footing. During this period, a total of approximately 125,000 ZEC were issued.
Standard Reward Period - through December 2019
After the slow-start period, from block 20,001 to block 653,599, each block had a reward of 12.5 ZEC. This period lasted for 633,599 blocks, resulting in a total issuance of:
The Blossom Upgrade
On December 11, 2019, the Blossom network upgrade was implemented at block height 653,600. This upgrade halved the block reward from 12.5 ZEC to 6.25 ZEC and reduced block times from 150 seconds to 75 seconds. This period lasted until the first halving at block height 1,046,400. During this period, the total issuance was:
The Founders' Reward
From the launch until the first halving in 2020, Zcash implemented a Founders' Reward. The block rewards were distributed as follows:
- Miners: 80% of the block reward.
- Founders: 20% of the block reward, which was distributed among the stakeholders who supported the initial development of Zcash, including early investors, the Electric Coin Company (ECC) team, and advisors. The Zcash Foundation did not receive any part of the Founders' Reward during this period.
Conclusion (GPT4)
The Founders' Reward, while innovative, has been a subject of both praise and criticism within the cryptocurrency community. On the positive side, it provided crucial funding that enabled the rapid development and maintenance of the Zcash protocol, ensuring that the project could attract top talent and resources. This financial support allowed for continuous innovation and a robust development roadmap, contributing to Zcash's advancements in privacy technology. However, critics argued that the Founders' Reward made Zcash less decentralized and more "corporate," as a significant portion of the block rewards went to a small group of stakeholders. Some viewed this as contrary to the decentralized ethos of cryptocurrencies, believing it created an uneven distribution of wealth and influence. Despite these criticisms, the Founders' Reward played a pivotal role in establishing and sustaining Zcash, demonstrating a unique approach to funding and development in the cryptocurrency space.
