I talked about a batch of digital currency wallets, and this is the first time I have heard of "programmable hardware hot wallets". Recently contacted by OdailySealBlockIntroduced to hardware walletsChip-level encryption technology and programmable rules engine, hoping to improve the security of the hot wallet to the same level as the cold wallet, and at the same time more flexibly meet the needs of users.
First, let's see what are the programmable rules.

The original SealBlock is more like a small host
Then, I will take multi-signature as an example to briefly describe the whole transaction process.
When you enable SealBlock for the first time, you need to connect the wallet to the monitor, keyboard and mouse, and access to the local area network wifi. At the same time as the "master wallet" is created, the private key is encrypted and stored in the hardware.
When using SealBlock's multi-signature rules, each "owner" of the wallet needs to firstMetaMask(A Chrome plug-in type, open source Ethereum wallet) Click "Sign" in the "empty wallet" to verify the identity. The "main wallet" in SealBlock is always connected to the Internet. After "collecting" the information returned by MetaMask, it confirms that the signatures are true and valid, and then requests the private key in the hardware to execute the transaction.
The signing of the master wallet takes place in the secure enclosure of the Intel SGX chip in the SealBlock (a black box "from the outside"). At this time, the executor of the transaction opens the computer browser, enters the receiving address (allowed by the white list) and the amount of transfer currency. In addition, rules such as whitelists can only be set on the management interface and verified by multi-signature.
Rick Wang said that in addition to MetaMask, SealBlock will also support more wallets that meet the personal message signature method.
After introducing the whole transaction process, we can feel that compared toimToken、KcashWaiting for the hot wallet APP of to C, SealBlock is not "operation-friendly".
However, the target users of SealBlock are token funds, exchanges, project parties, mining farms, and traders with high security requirements. For these customers, SealBlock also provides an interface to connect to the software hot wallet in the customer's existing solution, so the "retrofit cost" is not large.
Currently, SealBlock is in the first phase of the demo stage, and some companies are invited to try out the wallet. The first batch of ten partners can enjoy free services for half a year. SealBlock has reached a cooperation with the SWFT Blockchain transfer platform to switch its software wallet (including temporary wallet and withdrawal wallet) to a hardware solution to prevent authorized administrators inside the exchange from forging multiple signatures. The chip cannot be tampered with.
At the same time, since SealBlock does not plan to target the C-end public, the current production method is still self-assembly + adding an operating system, and has not entrusted a factory to manufacture or sell it to the public.
Rick Wang said that SealBlock does not want to use hardware sales as its main profit model, but wants to start with hardware and provide customers with a complete set of security services that combine hardware and signature rules.
In addition to product upgrades and iterations, SealBlock's future plans also include the release of SDKs to facilitate developers to define more flexible digital signature rules based on SealBlock and deploy more credible nodes.
According to reports, SealBlock has opened its first round of financing. VeriClouds, which incubated SealBlock, is an account security company with experience in hardware encryption. It has been established for more than 3 years and has served companies such as JD.com and Oracle. It is a strategic partner with Alibaba Cloud and Intel. People's seed round investment.
The team currently has 9 people. Rick Wang, Ph.D. in information security, is a senior researcher in network security technology at Microsoft Research Institute. He has multiple invention patents such as hardware encryption and blockchain security. His research results have helped technology companies such as Microsoft, Amazon, Google, PayPal, and Facebook improve product security. CEO Richard Yu, with 12 years of experience in IT product sales and team management, has worked for HP, EMC, etc. CSO Ricardo Diaz, 22 years of experience in information security technology, 13 years of experience in Oracle management and business development.
Among overseas hardware wallets, Ledger, which entered the market earlier, can be called a representative. According toOfficial website introductionKushenKushen, Odaily also introduced the use of two-dimensional code to complete the communication between hot and coldBepal, Customized separate hardware for signatureCobowait.Bidunwait.
