A brief history of Enterprise Ethereum Standards

The crosschain-id is a 32 byte hex string and with some bytes extracted from blockchain hash and some manually defined to characterize a blockchain. We also propose a registration and lookup service to retrieve blockchain metadata from the crosschain-id.

With the success of Bitcoin and Ethereum, various blockchains such as EOS, Ripple, Litecoin, Besu, Wanchain and the like have been developed and are growing at a fast pace.

There are also other private and consortium blockchains such as Hyperledger Fabric, Hyperledger Besu, Stellar, Corda, Quorum that only allow nodes with permitted identities to join the blockchain network. The growth of public and private blockchains imposes challenges for inter-chain interoperability, particularly when these chains are heterogeneous and incompatible.

CITF team noticed that there is a lack of unique identifier to charaterise and describe a blockchain. EIP provides a unique identifier to a blockchain to provide simple relay attack protection. This specification defines an integer for Chainid for a blockchain and sign the chainid into a transaction data and hence present attackers to send same transaction to different blockchains.

This specification will require blockchains to define a chainid and register the chainid in a public repository. The challenge of using an integer for chainid is that it is not broad enough to cover all blockchains and it does not prevent different blockchains using the same chainid.

Also, it does not address the issue for two forked blockchains having the same chainid. Hence there is need for a more robust blockchain identifier that will overcome these drawbacks, especially for crosschain operations where multiple chains are involved. A blockchain identifier crosschain id should be unique and satisfy the following requirements:.

We have considered various alternative specifications such as using a random unique hex string to represent a blockchain. A second alternative is simply using a genesis blockhash to represent a blockchain id for crosschain operations. The drawback of this is that this id does not have information about the property of the blockchain and it has problem when a blockchain is forked into two blockchain.

Crosschainid can be backward compatible with EIP The crosschain id contains a 4 byte segment to record the chainid based on EIP Collision of crosschain id: Two blockchains can contain the same crosschain id and hence making the mistakenly transfer assets to a wrong blockchain.

This security concern is addressed by comparing the hash of the crosschain id with the hash of the genesis block. If it matches, then the crosschain id is verified. If not, the crosschain id can be compared with the forked blockhash.

If none of the blockhash match the crosschain id hash, then the crosschain id cannot be verified. Preventing relay attack: Although crosschain id by itself is different from chainid and it is not signed into blockchain transaction, the crosschain id can still be used for presenting relay attack. An application that handles crosschain transaction can verified the crosschain id with its blockhash and decide whether the transaction is valid or not.

Any transaction with a non-verifiable crosschain id should be rejected. The crosschain-id are not required to be signed into blockchaid tx. For blockchains that do not cryptographically sign crosschain id into the blocks, the crosschain id cannot be verified with the blocks itself and have to be verified with external smart contract address and offchain utilities implemented based on the crosschain id specification.

The 16 bytes is the 16 least significant bytes, assuming network byte order. This is the Chain Id value that should be used with the blockchain when signing transactions. For blockchains that do not have a concept of Chain Id , this value is zero. Researve 0x00 as undefined chaintype. For all existing blockchains and for blockchains that do not have the concept of an owner , this field is zero.

Used to verify the integrity of the identifier. This integrity check is targeted at detecting Crosschain Identifiers mis-typed by human users. The value is calculated as the truncated SHA message digest of the rest of the identifier, using the least significant byte, assuming network byte order. Note that this checksum byte only detects integrity with a probability of one in This probability is adequate for the intended usage of detecting typographical errors by people manually entering the Crosschain Identifier.

EEA and OASIS Join Forces to Provide Nexus for Open Source Development of Ethereum Standards

Since inception, Ethereum has courted the attention of large companies. At the enterprise-level, no blockchain protocol offers the robust maturity and prospects of Ethereum-powered smart contracts. Sarson Funds has long covered the EEA and the powerful firms coordinating Ethereum best-practices across a diverse set of sectors. Thereafter, the EEA became a kind of standards organization for blockchain business, with an eye on a future state when the public blockchain might join with private implementations. With the start of the year behind us, many have already jumped into looking forward to what the crypto. Three Type of Wallets In the world of cryptocurrency, assets are not held in brokerage or bank accounts, but. The holidays have mostly come to a conclusion and everyone is getting back into the swing of the satoshies.
