We have added full support for multisig to the Console. One can now create a multisig address & use it to sign and send a transaction verified by several signatures.
Transactions with multi-signatures can also be generated off-line:

Tendermint Security Update
At 2:00 p.m. UTC Thursday, the Tendermint developer team released an unscheduled update to resolve several issues in the operation of nodes. Prior to that, nodes—as well as validators—had been vulnerable to DoS attacks.
In less than 30 minutes, we rolled out a node update v1.1.7, which uses Tendermint’s latest release with all security fixes.
We highly recommend that all owners of Minter nodes update their software.

Minter: What Is Next?
Hi, everyone! It is Daniil Lashin here, the lead developer at Minter.
Voting on the Network’s New Functionality
The Team and Validators have prepared several significant changes aimed to improve the network.
The first round lasts until June 23 and offers to add an option to “archive” the coins, allowing brands to re-use a particular ticker. This would substantially facilitate the onboarding of new customers and widen the blockchain’s possibilities.
The owner of the coin—i.e., creator address—will be the one to archive it. The creator rights, however, will be transferable. Archived coins will not be deleted, nor will their reserve be emptied. They will just change their name.
The voting also suggests setting the maximum number of validators to 64. Validators with small stakes (less than 1% of voting power) do not affect the decision-making process and decentralization of the network, but they slow it down drastically being equal participants of the consensus. The introduction of this limit would allow for the avoidance of extra loads with no losses.
The Team will proceed to develop the solution if the proposal is supported by a two-thirds validator majority.

Minter 1.2
Minter 1.2: Main Changes
Minter Blockchain Important News
On October 19, 2020, the network successfully upgraded to version 1.2. Since then, over 450,000 blocks have been generated. No critical issues have been detected. Thank you to all developers and validators who quickly updated their services!
Some news:
1. Golang security fix
On November 12, the Go language developer team released a vital update that eliminated a couple of vulnerabilities. One of the changes fixed the processing of large numbers that was causing applications to crash: crypto/rsa.VerifyPSS, crypto/rsa.VerifyPKCS1v15, and crypto/dsa.Verify might panic when provided crafted public keys and signatures.
We have re-compiled the v1.2.0 release with the latest version of Go (v1.15.5) so developers and validators can update their nodes. We suggest that you run tests on non-critical services before updating the main ones.
2. 1.2.1 Update
After the nodes moved onto v1.2, we have noticed quick increase in disk space consumption. After investigating, it became evident the problem was with the storage developed by Tendermint. Member of our core team submitted a pull request that was merged shortly afterwards. This fix will be included with Minter Node v1.2.1. To reduce the size of the base, it will be necessary to sync the node from scratch.
Full list of improvements:
-
- Increasing disk space issue resolved
- Minor Console bugs fixed
- Auto-load of minter-mainnet-3 genesis
Release Candidate: https://github.com/MinterTeam/minter-go-node/releases/tag/v1.2.1-rc5
We suggest that you run tests on non-critical services before updating the main ones.
3. Problem with Coin Owners
All coins that had been created using the most recent instructions were assigned an owner in network v1.2. Due to an error in genesis, however, some coins with other parameters (but with 100% of supply on one address) didn’t get an owner. A total of 64 coins have been affected.
We’re aware of the issue and will resolve it in one of the upcoming updates. That will require a simultaneous update of all validators.
Plans:
1. Blockchain security audit. We’ve prepared the node’s code for audit and plan to send out applications to several companies that could run it.
2. 2.0 development. We’re working on Minter 2.0 architecture and functionality and will soon publish a detailed document with denoscription.
3. Minter HUB development. Minter HUB is a cross-chain bridge with smart contracts (between Minter and Ethereum in the first place). The solution is unique in that all operations are made in a single transaction, which can be signed both from within Minter (e.g., exchange of any custom coin for one of the numerous ERC-20 tokens) and Ethereum (e.g., buying BIP for USDT).

Hi, everyone! Daniil Lashin here.
As 2020 nears its end, I’ve got some great news to share. Today is a very special day because we’re launching a public demo of Minter Hub. Hub is the next step in building the Internet of Money. It will interconnect Minter with other leading networks, starting with Ethereum.
You’ll be able to transfer literally any coin from Ethereum right to your BIP Wallet. They are: the ETH itself, stablecoins (USDT, USDC, …), wrapped BTC, tokenized assets (shares of companies, etc.), DeFi coins, and others.

Minter Hub
Minter Hub public demo announcement.
🚀 First Cross-Chain Transfers on Minter Mainnet!
Yesterday, as part of Minter Hub testing, the first transfers were sent from Minter to Ethereum and the other way around. It was the first step to launching a full-fledged Internet of Money that will allow to buy and sell any digital asset right within BIP Wallet. It will also let you create coins and loyalty points—traded against USDT, BTC, ETH, BIP, and any other asset by default—in minutes. Sending any mirrored coin (USDT, wBTC, wETH) will take minimum fees and a confirmation time of about five seconds.
Ethereum -> Minter:
1. Send
2. Receive
Minter -> Ethereum:

2. Receive
With Minter Hub, you’ll be able to transfer literally any coin from Ethereum to Minter. They are: the ETH itself, stablecoins (USDT, USDC, …), wrapped BTC, tokenized assets (shares of companies, etc.), DeFi coins, and others. Minter Hub validators will get 1% on the fees charged for moving coins from Minter to Ethereum and vice versa.
When running tests, we used the LASHIN coin, for which we issued an ERC-20 token on Ethereum. This clearly shows that mirroring can be done on either of the networks. Transfer of LASHIN and CHAIN from Minter to Ethereum and the other way around will be available to everyone once the UI development is finished. For these coins, the pairs will be launched on the Uniswap protocol, meaning anyone will be able to exchange them for USDT in a completely decentralized way.
For making these transfers happen, Minter Hub validators got 1% of the fees. The fee for sending transactions to Ethereum will be paid by the user separately (this functionality is underway).
A few technicalities
Minter Hub is based on Cosmos SDK and a modified Peggy solution that’s developed by the Cosmos team.
Minter Hub is supported by validators, here’s what they launch on their servers:
- Minter node
- Ethereum node
- Minter Hub node
- Ethereum Orchestrator, software that monitors the events on the Ethereum network and broadcasts them onto Minter Hub. It’s also responsible for sending withdrawal transactions to Ethereum.
- Minter Orchestrator, software that monitors the events on the Minter network and broadcasts them onto Minter Hub. It’s also responsible for sending withdrawal transactions to Minter.
Mirrored coins are locked on the MultiSig accounts of Minter Hub validators up until they are requested to be withdrawn.
Why is this one of the most important milestones in Minter’s history?
1. Minter becomes the easiest way to enter the crypto space. Fast and cheap transfers for most digital assets, interfaces that are easy to understand.
2. The bigger number of transactions and bigger gains for validators and delegators. With the arrival of Minter 2.0, the fees will be adjusted to the market, meaning that returns from the fees might surpass those from generating new blocks.
3. BIP holders get an opportunity to benefit from the exchange operations inside Minter carried out via the Uniswap protocol.
4. HUB holders get 1% on the fees charged for transferring coins from Ethereum to Minter and vice versa.
5. Last but not least: all Minter-powered coins become exchangeable with USDT, ETH, BTC, and other digital assets. All that in five seconds and at super-low fees.

⚛️ Cosmos SDK Security Patch by Minter Team
While developing Minter Hub, we located a critical bug in Cosmos SDK: a malicious actor could halt the operation of any public node with a 100-percent guarantee. We reported the issue in detail and informed Cosmos developers of our finding. Their team has released an update to eliminate this vulnerability:
https://github.com/cosmos/cosmos-sdk/releases/tag/v0.41.1
"This release includes two security patches, and does not introduce any breaking changes. It is highly recommended that all applications using v0.41.0 upgrade to v0.41.1 as soon as possible."
Our core team has been actively contributing to the Tendermint development since the very beginning: 6 issues, 1 global architecture proposal, 7 pull requests. And now we are excited to have the opportunity to help improve Cosmos SDK, too.
P.S.: Since Minter blockchain does not utilize Cosmos SDK, the identified problem does not affect it.

Binance Smart Chain @ Minter Hub
Transaction costs on the Ethereum network keep breaking new records: up to $100 for exchange operations and up to $20 for coin transfers.
That’s why the Minter Team has decided to additionally connect the Binance Smart Chain network as part of Minter Hub. This will make digital assets transferable not only between Minter and Ethereum, but between Minter and Binance Smart Chain as well. BSC will also provide Minter users with an opportunity to access even more digital assets.
BSC is based on EVM, which means we’ll be able to use what we’ve already developed for integration. At the moment, we’re running tests to see how compatible the current version of Minter Hub is with BSC.
