TProof
TProof.io
Create Decentralized Proof of Timestamp: Ethereum-based certifications for digital content existing prior a certain point in time. TProof is studied to support any amount of certification, as it's primarily based on two mainstream platforms: Ethereum and Arweave. Ethereum is where the certification happens, storing the hash of your file at a given timestamp. That combination is represented in the form of an NFT, free to move and trade as you with. Arweave is where you can optionally upload your file, making it public (and eternal). This step is optional, and suits those use cases where you want not just the hash, but also the file to be visible all over the world. Either you are a company, or a Web3 project that needs to generate a cryptographic proof around a digital content, you can integrate our Smart Contract.Starting Price: 0.01Ξ hash-only -

stampd.io
stampd.io
Timestamping and NFT creation of issued documents can allow a public verification of the issue history which is permanently recorded on the public blockchains. There is absolutely no method of potential malicious amendment at a later stage. Blockchain stamping as well as NFT minting allows a public verification of the document’s date, authenticity, origin, integrity & content without publicly exposing the content itself. Content signed by the user before timestamping, can be undeniably claimed to have been in the user’s possession & knowledge at the time of the blockchain time stamping. A simple reference to the respective public blockchain ledger transaction ID can undeniably prove this with absolutely no doubt. NFT linked with the original content is owned by the originator (the one in control of the address initially receiving the NFT). The owner can transfer their rights to someone else by sending the NFT to a different address. -

Everscale
Everscale
Everscale's architecture demonstrates that when software algorithms are implemented alongside a blockchain's infrastructure, the software itself ceases to be a performance bottleneck, thereby allowing transaction throughput to scale in direct proportion to network bandwidth. As such, Everscale’s architecture satisfies the three fundamental properties of a blockchain, scalability, security and decentralization. At Everscale we are demonstrating that distributed systems research is applicable to blockchain. Furthermore, and much to our surprise, it can be implemented using a mechanism that has been part of Bitcoin since day one which can be used to postdate transactions using block height instead of a timestamp. To achieve high network performance, you need reliable servers with fast connections. At the same time, in order to achieve sufficient decentralization, these servers should be owned by as many owners as possible. -

It is powered by Ouroboros, the ground-breaking proof-of-stake consensus protocol. In many cases, blockchain assets you exchange on the basis of your research may not increase in value, and may decrease in value. Similarly, blockchain assets you exchange on the basis of your research may fall or rise in value after your exchange. -

Oasys
Oasys
Oasys architecture is built for game developers, offering a high-speed, zero gas fee experience to users by combining the best of public L1 and private L2 blockchain technology solutions. Oasys is a public blockchain specializing in games. It is launching with support from renowned game companies to revolutionize "Blockchain for the games." Oasys is an EVM-compatible protocol that adopts the Oasys Architecture. This unique architecture consists of a multi-layered structure, hub-layer, a highly scalable layer 1; and verse-layer, a special layer 2 using Ethereum's layer 2 scaling solution. Normal optimistic rollups establish the network through trust in a mechanism to verify fraudulent transactions by fraud-proof from an unspecified number of parties. In contrast, Oasys' Optimistic rollups establish the network through trust in two factors. Oasys eliminates the 7-day challenge period from optimistic rollups and allows transactions to be approved instantly. -

Dusk Network
Dusk Network
Dusk Network is a technology for securities. An open-source and secure blockchain (DLT) infrastructure that businesses use to tokenize financial instruments and automate costly processes. A distributed Financial Market Infrastructure (dFMI) should provide a clear and final settlement of transactions. Moreover, the settlement of transactions should be instant or near-instant (<15s). The popular proof-of-work consensus mechanism used by Bitcoin and Ethereum does not address these requirements. Therefore, we designed a more performant consensus called Succinct Attestation agreement that enables instant settlement of transactions within 15 seconds. Powered by zero-knowledge technology, organizations use the dusk networks to issue tokens that are governed by privacy-preserving smart contracts. Harnessing the power of DLT while respecting confidentiality agreements, and data protection legislation. -

Starknet
StarkWare
Starknet is a permissionless decentralized ZK-Rollup operating as an L2 network over Ethereum, where any dApp can achieve unlimited scale for its computation, without compromising Ethereum's composability and security. Starknet achieves scale, while preserving the security of L1 Ethereum by producing STARK proofs off-chain, and verifying those proofs on-chain. On Starknet, developers can easily deploy any business logic using Starknet Contracts. Starknet will provide Ethereum-level composability, facilitating easy development and compounding innovation. The STARK Prover powers the StarkEx scalability engine, and has already demonstrated the ability to process 600K transactions in a single proof on Mainnet. -

Terra
Terra
Anchor Protocol allows Terra stablecoin deposits to earn stable yield, powered by block rewards of leading proof-of-stake blockchains. Terra stablecoins offer instant settlements, low fees and seamless cross-border exchange - loved by millions of users and merchants. Mirror Protocol allows the creation of fungible assets, “synthetics”, that track the price of real world assets. Mirror synthetics are intended to be used as key building blocks in smart contracts, and to bring the world’s assets to the blockchain. Build smart contracts in Rust, Go, or AssemblyScript. Run on multiple chains, connected by the Cosmos IBC. Use Terra stablecoins, onchain swaps, layer 1 oracles as primitives. Expose dApp userbases to Terra's payment services in a permissionless fashion. Terra aims to make its stablecoins available to every developer on every blockchain. Now live on Ethereum and Solana, and coming to more soon. -
