REAL-TIME PAYMENT BLOCKCHAIN

Upcoming GRAFT Network Difficulty Algorithm Update

The code release for the upcoming GRAFT network update, which includes ASIC resistance, enhanced difficulty adjustment algorithm, and minor bug fixes, is almost ready to go, and we are on track to release it on Monday, April 9th, with the actual switch scheduled to be triggered around April 16th (the block number will be announced later). Currently, we are conducting regression tests. The ASIC resistance code in conjunction with the new difficulty algorithm is supposed to minimize the possibility of hashrate attacks – when significant hashrate power (generated by ASIC or large GPU miner) is connected for relatively short period of time and making it difficult for other miners to compete and solve the blocks, until the existing algorithm adopts to a new hashrate and adjusts the network difficulty. This is how the existing algorithm reacts to sudden hashrate spikes in the mainnet: The following graph shows how the updated algorithm adjusts the difficulty much better after the simulated hashrate attacks: Although we think the upcoming network update will be sufficient to protect the blockchain from the majority of hashrate attacks, we are also working on original, even more enhanced version of the difficulty adjustment algorithm, which is supposed to provide even better, more “symmetrical” and balanced response to any hashrate fluctuations. Since such enhancements require significant testing, which is very time consuming, we are planning to include it in the next network update (the one after the upcoming update on April 6th), along with the merge of recent Monero changes. As usual, we will follow up with more details soon. Stay tuned!

About GRAFT Project

GRAFT is a blockchain based payment processing network the functions similarly to a credit card processing network with off-chain authorizations and in-network atomic swap based interchanges. The network is completely decentralized, able to work cross borders and adapting to local regulatory environment.

In addition to decentralization, GRAFT solves four biggest problems that exist in cryptocurrency at a point-of-sale today - privacy, speed, fees, and integration.

Economically, it’s a two layer (proof-of-work and proof-of-stake) blockchain with proof-of-stake based authorizations with participants able to benefit both for mining and staking

Finally GRAFT is open-platform, open-source, non-for profit community project. To support GRAFT Network, please donate BTC to: 39UBccrXeKBtoxeKXPqsXxPFnhzt6bueSY
