Finishing_GRFT_Roadmap-4.png

The next large milestone for GRAFT is implementing checkpointing (a way to achieve finality and avoid various double spend exploits between the layers of the multi-layer blockchain).

We have been looking at checkpointing solutions from Dash, LOKI, and Ethereum Casper. All of them use slightly different approaches for validator quorum selection, conflicting checkpoints resolution, revision attacks, catastrophic crashes, etc. Our goal is to pick the best model for GRAFT by leveraging the work that’s been done on these other platforms.

In the next couple of weeks we will be working on putting together a proof-of-concept for GRAFT checkpointing, at which point we will publish the design to collect comments and proceed with full implementation.

On a separate subject, one of the community devs who was interested in helping Slava with Lyra has stepped up to continue Lyra development and has already built an impressive showcase app, which he’s planning to publish shortly. Little too early to “count the chickens”, but looking quite promising that Lyra development will continue.

The post Dev Update – Checkpointing appeared first on Graft Blockchain.

    • Hey guys. Can somebody help me? I wanted to have some fun and start mining Monero.  This is my config:    {     "autosave": true,     "donate-level": 2,     "cpu": true,     "opencl": true,     "cuda": true,     "pools": [         {             "url": "pool.hashvault.pro:3333"         },         {             "url": "pool.hashvault.pro:443",             "user": "-------------",             "keepalive": true,             "tls": true         }     ] }   I generated on website. Can you help me with user? What should I put there? A wallet address? (i have Coinomi wallet). Where to get it? Don't have any serious expectations about mining but i have a PC with two RTX 3060 so maybe i will dig something in free time just to be happy, even if it will be worth 1$ 🙂 Thank you in advance.

    • Dear Community,   Reading the "Getting Started" section in the Pool area and some threads on the Forum, I still have a little question.  Whom do you recommend mining solo?  The hash rate seems to be the same whether I do SOLO mining or not.  Thanks!

    • Update: Having applied the Script from the thread linked to above, I get another outcome. Is that as it is supposed to be??

    • Dear Community,    I would like to have these Hugepages supported now :-) I am thus referring to this thread here, which seems to be closed. I have tried the following to enable hugepages AND get them working until 1 GB.  See me output: Thanks so far! Bee *** Question: Why is HUGEpages 1 GIg not available?  How do I set the value correct?
