+# FAQ for Kadena’s Public Blockchain
+
+[Kadena has released mainnet mining](https://medium.com/kadena-io/kadena-releases-mainnet-mining-and-announces-token-sale-e4a8866da56)
+to the public, inviting the mining community to begin solving blocks on the
+Kadena public blockchain. Kadena’s network has come alive with activity as
+miners from all over the world participate on the Kadena network.
+
+In addition to mainnet mining, Kadena also announced
+[Block Explorer](https://explorer.chainweb.com/), a tool that allows for
+real-time monitoring of Kadena’s parallel chains. View the propagation and
+braiding of blocks, or dive into any block for key details such as block height,
+PoW hash, neighbors, and payload.
+
+The Kadena network has experienced significant growth in its first few weeks:
+
+- Before the end of week one, the hash rate grew to over 500 GH/s through CPU
+  mining alone.
+
+- Before the end of week three, the network achieved a hash rate of over 4.0
+  TH/s with the introduction of GPU mining.
+
+Kadena will continue to listen to the community and make improvements that
+benefit the network’s health and accessibility.
+
+For those with general questions about participating in Kadena’s mainnet, read
+on for more information.
+
+## Where can I find more information about Kadena tokens?
+
+Read the
+[token economics breakdown](https://medium.com/kadena-io/the-kadena-token-economic-model-8090d7545eef)
+for more information on the Kadena token model.
+
+**What hashing algorithm does Kadena use?**
+
+Blake2s_256
+
+**Where can I find the latest release of binaries?**
+
+Our latest releases are always open-sourced on GitHub. Chainweb Node is
+[here](https://github.com/kadena-io/chainweb-node/releases) and Chainweb Miner
+is [here](https://github.com/kadena-io/chainweb-miner/releases). Make sure you
+are on the most up-to-date releases, or else it’s possible that your
+_miner/node_ will not work properly.
+
+**What kind of computer is required to run a Kadena public blockchain node?**
+
+As of publication, the minimum requirements are 2 cores and 2 GB RAM. However,
+our recommendation is to use 4 cores and 4 GB RAM.
+
+Currently, disk space is rarely an issue and a few gigs should be more than
+enough. Note that the amount of data in the blockchain will continually grow and
+will eventually consume a more significant amount of disk space. Please plan
+accordingly.
+
+**What is the target block time?**
+
+The target is to reach a new block height every 30 seconds and there are 10
+blocks (i.e. 10 chains) at every height.
+
+**How can I check my account details, including balance?**
+
+You can check your account details by sending a Pact local API request calling
+*coin.details *on any node.
+
+For more on how to do this, see:
+[Pact Local Queries](https://github.com/kadena-io/chainweb-node/wiki/Pact-Local-Queries)
+
+**How can I tell if a node is minable?**
+
+We recommend that you connect to our bootstrap nodes that are closest to your
+geography and turn on mining. You can find our list of bootstrap nodes
+[here](https://github.com/kadena-io/chainweb-node/wiki).
+
+You can also test if public nodes are minable by pointing your miner at any of
+the available nodes and see if it starts mining. This is easiest if you set the
+default log level to debug. For example:
+
+_./chainweb-miner cpu — cores 2 — node us-w2.chainweb.com:443 — miner-account
+<some account> — miner-key <some key> — log-level debug_
+
+**How come my balance doesn’t exist on all chains?**
+
+Kadena’s public blockchain architecture is unique in the fact that account names
+are not global entities. Account names, as a result, only exist for the chain(s)
+on which you create them. Consequently, you will also have a distinct balance on
+each chain. The easiest way to get your account on all chains right now is to
+mine.
+
+**Can my account name be different from my public key?**
+
+Our public blockchain supports
+[cross-chain transfers](https://github.com/kadena-io/chainweb-node/blob/5ba732d8d003d00afb68053bab6b2f549d6157bc/pact/coin-contract/coin.pact#L408)
+which allow you to unify your accounts across all chains, but there is always
+the possibility that if you wait, you will not be able to reserve the account
+name you want. We recommend reserving an account name at your earliest
+convenience.
+
+**Need more support?**

+# Kadena 1.1 Release Schedule/Chainweb Transfers Roadmap
+
+_**12/4/19 Update:** Thank you to one of our community members who has
+identified a potential security vulnerability. Coming back from the Thanksgiving
+holiday, our team investigated this yesterday and has confirmed that it needs to
+be addressed. Since we want to be cautious and diligent about preserving network
+stability and token value, we are moving the date of enabling token transfers to
+**December 17**. Please visit Kadena’s
+[Discord](https://discordapp.com/invite/bsUcWmX?source=post_page---------------------------)
+channel to share your comments and questions._
+
+As part of our ongoing efforts to keep the community informed, we are sharing
+the release schedule for Kadena 1.1, which enables coin transfers on the Kadena
+public blockchain. After the initial release, the transition from version 1.0.5
+to 1.1 will take place over three stages from December 2 to December 6, 2019,
+followed by a ramp-up period of transfer volume.
+
+## Kadena 1.1 Software Release (December 2):
+
+- Kadena 1.1 is required to operate the blockchain after the rollover is
+  complete.
+
+- It contains the necessary protocol changes to allow coin transfers on the
+  platform.
+
+- It also contains important improvements and fixes for the protocol, P2P layer,
+  transfer performance, and stability.
+
+## Soft Rollover Stage (December 2–5):
+
+- Kadena versions 1.0.5 and 1.1 are both fully operational and cross-compatible.
+
+- Both versions continue to mine empty blocks only (no transfers).
+
+- Miners are encouraged to update as soon as possible so we can address any
+  unforeseen issues with the upgrade in the soft rollover stage.
+
+## Hard Rollover Stage (December 5–6):
+
+- All Kadena versions 1.0.x will stop mining new blocks at 00:00 UTC December 5.
+  Miners will have to upgrade at this point to keep mining.
+
+- Kadena version 1.1 will continue to mine empty blocks as before.
+
+## Kadena 1.1 Transfers Enabled (December 6):
+
+- At the end of the hard rollover stage, the Kadena blockchain will start
+  accepting coin transfers and other coin-related operations.
+
+- We will provide documentation on methods for performing transfers.
+
+## Transfer Limit Ramp-up
+
+Building on the success of the limited beta release on October 30, the Kadena
+1.1 blockchain will gradually ramp up transfer throughput over the following
+weeks after December 6, so we can continue to address issues that might arise
+with the new functionality.
+
+On December 6, Kadena 1.1 will have a low gas limit that defaults to
+approximately 10 transfers per block. We plan to increase this limit
+periodically with close coordination with the mining community on an
+approximately weekly basis. Initial increases will result in block transfer
+limits of 25, 50, etc. We expect to continually release upgrades during this
+time to improve transfer handling and enable greater throughput.

+# Kadena and Rymedi Validate Quality of Medicinal Products on Blockchain
+
+[Kadena](http://www.kadena.io/), the first blockchain technology company to come
+out of JP Morgan’s Blockchain Center for Excellence, announced a strategic
+partnership with [Rymedi](https://www.rymedi.com/), providers of a data platform
+revolutionizing healthcare supply chains. Rymedi’s integration with Kadena’s
+blockchain provides immutable supply genealogy and multi-partner data access,
+extending existing client capabilities, ranging from tracking pharmaceutical
+supply chain in developing countries such as Mongolia and Kenya to assisting
+hemp/CBD growers and extractors looking to bring the safest products to market.
+
+By integrating Kadena’s blockchain into its existing platform, Rymedi further
+empowers consumers as well as supply chain members with vital data that’s
+previously been unavailable. By scanning a simple barcode with their cell
+phones, customers can get data about a product’s origin and journey. This
+validates purchasing and authenticity, especially useful in geographies and
+industries where fraud and quality concerns remain potentially life-threatening
+issues.
+
+“The partnership with Rymedi shows how blockchain technology can positively
+contribute to crucial aspects of the healthcare supply chain,” said Will
+Martino, Founder and CEO of Kadena. “Many times, illegitimate products can mean
+life-or-death for vulnerable communities. We look forward to being part of a
+solution that helps prevent the tampering of medicinal products.”
+
+David Stefanich, CEO of Rymedi shares, “With their deep experience in financial
+markets and transaction data, Kadena is a uniquely aligned partner for us. With
+several use cases already live around the world, we’re making plans to broaden
+our partnership and offer even more value to our customers across healthcare
+data-silos.”
+
+Blockchain’s capacity to guarantee quality in medicinal products allows everyone
+from suppliers to customers to have greater confidence. Kadena and Rymedi look
+forward to further collaborating on a data platform that ensures verifiable
+medicinal products while also discovering new solutions that can benefit
+communities across the globe.
